Her team collates and analyses recorded measurements and checks for anomalies in switchgears and transformers. Maizan Binte Abdullah performing condition monitoring checks. (Photo was taken before circuit breaker) When Maizan joined SP 38 years ago, she was doing something quite different. Learning and Adapting After completing her post-secondary education, Maizan started as an apprentice in the Electro Mechanical Maintenance Fitting department at the Public Utilities Board (PUB). Subsequently, she was posted to the Meters section to conduct meter maintenance activities. Maizan (in blue attire) and her former colleagues from Meters section enjoying a durian feast together. When PUB corporatised in 1995, she moved to SP where she continued with the Meters section for the next 14 years. She would have thought that would be her home for the rest of her career. However in 2019, she was seconded to CM. This change to field work seemed to be unsurmountable, having been in a deskbound administrative role for more than 20 years. “Given my age, I was very worried that I may not be able to cope with the demands of the new role. However, I recognised that I needed to move out of my comfort zone and acquire new skills to remain relevant,” shared Maizan. After going through training and with strong support from her team and the management, Maizan is settling so well at CM that she became the team lead for North Zone in the same year. A lifelong learner, Maizan completed her part-time Diploma in Engineering (Power Engineering) programme at Singapore Polytechnic in May 2020 under SP’s sponsorship. She soldiered on despite having to juggle her new role and studies. “There were times when I felt overwhelmed and felt like giving up. I am glad I had the support from my family, my boss and colleagues who encouraged me to persevere. This experience has been very enriching, and I look forward to continue growing!” exclaimed Maizan. Growing despite COVID-19 With this mindset, Maizan and her team continued to learn new ways of working to carry out their duties during the Circuit Breaker period. Maizan and her colleagues use handheld detectors to detect for abnormalities in the network. This is to prevent faults from developing and causing power disruptions. “Due to the need to minimise contact, we had to stagger our working hours. This is a challenge as CM relies heavily on teamwork. We also had to wear a mask when doing checks in the substation, which is an enclosed space and often hot and humid,” shared Maizan. However, Maizan takes it in her stride. She performs daily check-ins with her team members via instant messaging and tele-conferencing. With a sparkle in her eyes, she said, “Work is never the same every day. I take this as an opportunity to grow – to be stronger and better in managing change and future crises.” — 27 July 2020 TAGS LIFELONG LEARNERPEOPLE OF SPRELIABILITYCONDITION MONITORING YOU MIGHT BE INTERESTED TO READ Guardians of the Grid Executive Engineer Mohamad Elmi Sha Bin Mohamad Nasir and his colleagues at SP Group's Distribution Control Centre are part of the unit that oversees Singapore’s electricity grid round the clock.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation The Doctor Is In: Grid Health Checks Prevent Issues RELIABILITY Reading the “pulse” of network equipment, Senior Engineer Dr Lai Kai Xian can tell whether insulation material within the equipment may be breaking down. Like any good physician, Dr Lai Kai Xian is skilled in being able to look, listen and feel. The key difference is that his patient is Singapore’s electricity network, and he diagnoses the grid’s health conditions and fixes these even before they become problems. The 35-year-old electrical engineer is one of eight specialists in the SP Group’s Condition Monitoring team who keeps a close eye on the 11,000 substations and over 28,000km of cables that make up the grid. They are supported by 44 technical officers and technicians who conduct regular health screenings of all equipment on the network, and recommend deeper investigations or treatment when necessary.  Condition Monitoring Senior Engineer Dr Lai Kai Xian uses devices that require various senses – hearing, sight and touch – to assess equipment health, much like a medical doctor. Technicians take the network’s temperature using thermal guns, and listen for abnormal sounds using sensors coupled with headsets that make high frequency sounds audible. Special probes listen for the “pulse” of the equipment, and normal sounds need to be distinguished from ones that could indicate a potential problem. Sounds called transient earth voltage signals could point to internal voids in liquid, air or solid insulation material that are wrapped around cables. These kinds of “partial discharge” summon more varied equipment to pinpoint the source of an abnormality, and allow for early intervention. “These markers tell you where more investigation is needed or where problems could potentially lie so they can be solved before they get any bigger,” explains Dr Lai. He had focused his PhD studies on condition monitoring, and thanks his parents for the opportunity to have done so in Australia. SeniorEngineer Dr Lai Kai Xian (left) with his parents (right) at the 2010 University of New South Wales graduation ceremony. He was awarded a Doctor of Philosophy in Electrical Engineering. Like any emergency room, the most critical cases are attended to first, and more tests can be ordered to make a more accurate diagnosis. It can sometimes make for an intense work day, he concedes. But until his first child arrives in October, the grid is his baby – indeed his personal hobbies include reading technical articles about power systems and new technologies. Condition monitoring affords the grid an additional layer of insurance over scheduled maintenance, making it even more reliable, says Dr Lai. According to Dr Lai, an average of 70 potential problems have been avoided each year over the last five years. And unlike scheduled maintenance work which may require a piece of equipment to be taken out of service to be checked, repaired, or replaced, this pre-emptive approach is non-invasive, requiring no shutdowns. In the long run, keeping the health of a piece of equipment in check also means it lasts longer, he says. More companies are now catching on to these benefits, says Dr Lai, adding that he had trouble finding a job specifically in condition monitoring until he joined SP, a big believer in “preventive medicine”. Online monitoring is also continuously leveraged by SP for the larger 400kV and 230kV substations that make up Singapore’s transmission network, with sensors transmitting real-time data to Dr Lai’s lab. New technologies that can make the grid more robust are also regularly assessed, adds Dr Lai, also a “doctor-on-call” for casual queries from other departments, thanks to friendships forged with colleagues through weekly badminton sessions. Getting to the root of the problem is one of the things he relishes most about his role in SP’s network reliability, especially since diagnosis can be as much of an art as a science, and prompts spirited debates. “You need to be able to look beyond the obvious with data.

Media Release Leveraging Digital Solutions to Future-Proof Singapore’s Energy Grid As part of Singapore’s energy transition, the Energy Market Authority (EMA), together with industry partners, have embarked on digital projects to future-proof the nation's energy grid infrastructure. There has been good progress in the development of Singapore’s first Grid Digital Twin and Distributed Energy Resource Management System, and they will continue to be developed over the next few years. These projects will serve to enhance the resilience and reliability of Singapore’s electricity grid and support the deployment of cleaner energy sources. Grid Digital Twin 2. Singapore embarked on the Grid Digital Twin in 2021 with the aim of enhancing Singapore’s grid resilience, reliability, and support the deployment of cleaner energy sources. The Grid Digital Twin, comprising two key models - Digital Asset Twin and Digital Network Twin - is a virtual replica of the physical grid network and infrastructural assets. Created in collaboration with Government agencies, industry players and academia, research and development for Singapore’s first Grid Digital Twin for the national power grid has demonstrated good progress. Digital Asset Twin 3. The Digital Asset Twin is a virtual replica of SP Group’s electricity network assets. Developed by the SP Group, in collaboration with Nanyang Technological University (NTU), the Digital Asset Twin aims to enable network operators to monitor and analyse the condition and performance of grid assets, in order to mitigate potential issues. When fully developed, it is envisaged that the Digital Asset Twin will also enable informed decisions for prioritised and timely renewal and maintenance of grid assets. 4. Through in-house digital development capabilities, SP Group has built the core of the asset dashboard as well as key Artificial Intelligence (AI) engines and algorithms to integrate with sensors in real time. The SP-NTU Joint Lab will provide components of an Asset Health system and cost-effective condition monitoring sensors. SP Group targets to deploy a pilot by 2025. As costs of sensors, digital and communication solutions reduce, they can potentially be applied to the large number of distribution assets, such as the 18,000 transformers across SP’s 12,000 substations. Digital Network Twin 5. EMA has also collaborated with partners such as S&TPPO, A*STAR’s Institute of High Performance Computing (IHPC), and TUMCREATE to develop the Digital Network Twin within the Singapore Integrated Transport and Energy Model (SITEM). With the development of the Digital Network Twin, it enables SITEM to make use of advanced modelling and simulation software to model the impact of additional Electric Vehicle (EV) demand on the grid and identify necessary infrastructure upgrades under different scenarios. This has provided insights to EMA and SP Power Grid (SPPG) on how substation capacity could be optimised to support EV charging. The Digital Network Twin is currently undergoing the next stage of translational research and development in order to deploy the developed solutions into an end-user software solution usable by EMA by 2025. The software solution will help to assess the impact of significant demand changes expected in the distribution grid as energy sector decarbonises. 6. A*STAR has also incorporated high-resolution electricity demand results obtained from the Digital Network Twin into a national-level energy systems model that aims to optimise Singapore’s long-term decarbonisation pathways. The effort has yielded positive initial outcomes through the identification of potential ways to reduce investment costs in the power sector over the next 30 years, as the nation seeks to achieve net zero emissions by 2050. EMA will also work with A*STAR and other partner agencies, through the Centre for Energy and Emissions Modelling (CE2M), to further improve long term power sector decarbonisation planning. 7. Through these initiatives, Singapore will have smarter and more efficient ways of monitoring and predicting the health of the nation’s grid assets and network. In addition, the Grid Digital Twin allows for a risk-free environment to study and test different scenarios. This will help future-proof Singapore’s power grid by ensuring that it is well-equipped to manage increasing electricity demand and changes in energy supply, while maintaining reliability in grid operations. Distributed Energy Resource Management System (DERMS) 8. Distributed Energy Resources (DERs) like solar generation systems, battery Energy Storage Systems (ESS), and Electric Vehicles (EVs) are likely to proliferate in the coming decades. This is because solar power generation and battery ESS are expected to become cheaper and more efficient, given ongoing research and development efforts as well as economies of scale. As such, it is increasingly vital to ensure that Singapore’s grid infrastructure is able to support the integration and deployment of cleaner energy sources.   9. To better optimise the management of small-scale DERs such as solar and EVs across the network, SPPG has embarked on pilot development for a Distributed Energy Resource Management System (DERMS). DERMS is a monitoring and control platform which aims to support SPPG’s network operators with real-time information and control capabilities to optimise DER connections. 10. SP Group has carried out a proof-of-concept in 2021, to explore use cases where monitoring and control of DERs could support network operations. From this first phase, monitoring and control solutions were trialled on test setup to gain first-hand experience and identify potential applications for Singapore’s context. 11. The next phase of the DERMS pilot is focused on solar forecasting and capabilities to prepare for increasing EV adoption, and will be test-bedded at selected SP substations. When fully developed, DERMS will be able to support network operators in the sustainable integration of solar and EV-related DERs into the network, while effectively managing reliability and system costs.

A digital twin is a virtual model of physical infrastructure, processes and systems that can carry out various functions such as intelligent data analysis, computer modelling and simulation and machine learning to support users in improving planning and decision-making processes. 2. The digital twin of Singapore’s national grid will comprise two key models: a. Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. Through in-house digital development capabilities, SP Group has built the core of the asset dashboard and the initial key AI engines and algorithms to integrate with sensors in real time. The SP NTU Joint Lab will provide components of an Asset Health system and break-through cost effective condition monitoring sensors. SP Group targets to deploy a pilot by 2025. As costs of sensors, digital and communication solutions reduce, these digital solutions can potentially be applied to the large number of distribution assets, such as the 18,000 transformers across 12,000 substations.  The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory[1]. b. Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)[2], the Network Twin is able to provide EMA and SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. EMA and agencies such as A*STAR’s IHPC, S&TPPO, and TUMCREATE, have developed the Singapore Integrated Transport and Energy Model (SITEM) to model the impact of additional Electric Vehicle (EV) demand on the grid and identify necessary infrastructure upgrades under different scenarios. SITEM has provided insights on how substation capacity can be optimised to support EV charging. The first prototype Network Twin was developed as part of the SITEM project by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project was funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).  IHPC is currently undertaking the next stage of translational R&D that aims to deploy the Network Twin into an end-user software solution usable by EMA engineers by 2025.  EMA will work together with A*STAR and other partner agencies in the Centre for Energy and Emissions Modelling (CE2M), which seeks to support long-term national decarbonisation planning. The initiative aims to develop a federated systems architecture that integrates the national energy system model, with sectoral models such as power and transport.  The modelling effort would better inform Singapore’s net-zero strategy, including our future power grid. 3. Key benefits of the Grid Digital Twin are: a. Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.  b. Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads. c. Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.

VOLTAGE DIP MANAGEMENT Introduction Why this guidebook? This guidebook aims to provide customers the knowledge and management of voltage dips. As most voltage dips are caused by electrical equipment failure from all stakeholders connected to the network, it can’t be totally eliminated. As such, this guidebook covers the preventive measures taken by different stakeholders to minimise the occurrence and impact of voltage dips. It includes techniques for voltage dip monitoring, mitigating measures and case studies from past experiences. With the principles, techniques and best practices outlined in this guidebook, we believe it will help Customers make informed decision in managing voltage dips depending on their risk appetite. Collectively, let us work together to prevent voltage dips in the network.

Voltage dip, as defined internationally (European Standard EN50160), refers to a sudden voltage reduction of more than 10% with duration between 10 milliseconds and 1 minute. (Fig 1) Voltage (Vrms p.u.) 1.0 0.9 Nominal Voltage Magnitude Fig. 1. Voltage Dip (RMS) Timeplot Duration Time (ms) 1.2 Causes of Voltage Dips Voltage dips are mainly caused by equipment failures at power grids, customer installations, power generation plants, or accidental damage to power cables. Voltage dips can also propagate from one part of the network to another part of the network and also across different utilities because they are interconnected. 1.3 Impact of Voltage Dips Unlike power outages, voltage dips do not interrupt the electricity supply. Instead, they result in a temporary voltage reduction. Voltage dips can have various impacts, ranging from momentary light dimming to lifts, escalators, and machines stopping, disrupting your operations. 1.4 Voltage Dips are unavoidable in the Network Knowing the causes of voltage dips, it is understandable that voltage disturbances are a natural part of the network and is unavoidable. Although it’s not possible to completely eliminate voltage dips, everyone can certainly work together to minimise the occurrence and mitigate its impact. 5 CHAPTER 02 Preventive Measures Against Voltage Dips This chapter provides the overview of the preventive measures taken by various stakeholders – the electricity regulator (EMA – Energy Market Authority), the transmission licensee (SPPA – Singapore Power Assets) and the connected customers to minimise voltage dips occurrences. 6 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS 2.1 Policies by EMA EMA aims to ensure a reliable and secure energy supply, promoting effective competition in the energy market and developing a dynamic energy sector in Singapore. EMA takes various stringent measures such as enforcing policies for various stakeholders to comply and regulatory actions on the errant stakeholders (which will be covered in section 2.1.2) to minimise the occurrence of voltage dips in the network. It believes that the occurrence of the voltage dips can be minimised through proper maintenance of equipment. Acknowledging that voltage dips is inevitable, EMA had also indicated in the Transmission Code that Customers whose operations cannot tolerate voltage fluctuations should install their own power quality devices, such as voltage stabiliser, uninterruptible power supply (UPS). 2.1.1 Policies for prevention of cable damages Voltage dips may arise from damages to underground cable system due to earthworks. Hence, EMA has set out policies to manage and safeguard cables from damages 1 . The Electricity Act (Chapter 89A) requires that the earthwork contractors must obtain cable plans from transmission licensee (SPPA) and engage a Licensed Cable Detection Worker (LCDW) to ascertain the location of high voltage electricity cables in the work area before starting earthworks. The contractors shall submit the Notification for Commencement of Earthworks (NCE) to SPPA at least 7 calendar days before they commence earthworks in the vicinity of any high voltage electricity cables. Upon receiving such notification, SPPA will issue a Letter of Requirements (LRe) for earthworks. All contractors are required to comply with SPPA’s LRe. EMA and SPPA have implemented the Registered Earthworks Supervisor (RES) scheme to enhance prevention of cable damages. The RES scheme aims to ensure site supervisors are competent in cable damage prevention measures and adhere to them as required under SPPA’s LRe. Only site supervisors who have passed the RES course, and are registered as a RES with SPPA, are allowed to supervise worksites in the vicinity of high voltage cables and medium/high pressure gas pipelines. Any non-compliance with SPPA’s LRe would result in demerit points being given to the RES. The RES will have his registration pass suspended or revoked if his total number of demerit points exceeds a specified threshold. EMA also encourages the contractors to refer to SS576:2019 (Code of Practice for Earthworks in the Vicinity of Electricity Cables) as a guide to best practices for earthworks near underground electricity cables to prevent cable damages. For cable damages due to negligence of a party, fines and penalties are imposed (maximum of S$1 million and/or a jail term of up to 5 years under the Electricity Act). Additionally, EMA has specific requirements for the transmission licensee and the connected customers on voltage dip prevention and the implementation details are provided in section 2.2 and section 2.3 respectively. 1 https://www.ema.gov.sg/Earthworks_Contractors.aspx, Accessed on 06/06/2023 7 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS 2.1.2 Regulatory actions on occurrence of voltage dips EMA investigates each voltage dip incident and enforces regulatory actions against any stakeholders who fail to uphold the integrity of their high voltage equipment. According to Section 85(1)(a) of the Electricity Act (Chapter 89A), any person who removes, destroys or damages any electrical plant or electricity cable which is part of a transmission system that belongs to or under the management or control of an electricity licensee shall be guilty of an offence and shall be liable on conviction to a fine not exceeding S$1 million or imprisonment for a term not exceeding 5 years or to both. EMA establishes performance standards and impose financial penalties on SPPA where voltage dips results from equipment failure that could have been prevented. In the event of any shortcomings, EMA will take regulatory actions against SPPA and mandates the implementation of measures to prevent recurrence. Furthermore, EMA possesses the authority to take regulatory measures against generating companies and connected customers if their equipment maintenance falls shorts, leading to adverse network effects. Regardless of whether a customer has maintained their high voltage electrical installation, a customer whose installation has caused three voltage dips within 24 months is required to engage an independent licensed electrical engineer to perform an audit and corrective actions. The Licensed Electrical Engineers (LEE) with three high voltage installations causing voltage dips within a 24-months period are also accountable to appear before an Inquiry Committee of three Professional Engineers appointed by EMA. Failure to ensure proper maintenance of these electrical installations could lead to the suspension of the LEE’s license. 2.2 Preventive Measures by SPPA SPPA has devised strategies to meet the stringent regulatory requirements regarding power quality and reliability of the grid through condition monitoring and preventive maintenance of the switchgears, transformers, cables, and other electrical equipment. Over years, the focus of condition monitoring specifically partial discharge monitoring, has shifted from onsite to online monitoring, substantially averting failures and potential voltage dips. To bolster the reliability of Singapore’s electricity network, equipment renewal program is in-placed. Network segmentation has also mitigated the impact of network faults. For the protection of high voltage cables, certain extra high voltage cables (230kV and 400kV) are securely housed within dedicated cable tunnels. Construction sites are regularly patrolled to ensure adherence to earthwork procedures. SPPA is also committed to knowledge-sharing through workshops, courses, and other educational programs aimed at enlightening customers and contractors on their responsibilities regarding power quality. The subsequent section elaborates on specific steps taken by SPPA to ensure power quality in Singapore. 8 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS 2.2.1 Condition monitoring and preventive maintenance Condition monitoring techniques such as partial discharge monitoring (PDM), ultrasonic scans and thermal infrared scans are performed on the network equipment. Online PDM is a permanent monitoring system offering continuous insulation condition status while electrical equipment is in operation, pre-emptively identifying potential defects before they fail. Within Singapore’s network, online PDM is primarily applicable to transmission equipment including high voltage gas insulated switchgears (400kV, 230kV, 66kV and selected 22kV), and gas insulated power transformers. A dedicated team at SPPA continually monitors and analyses data from the PDM system for anomalies. Equipment not fitted with online PDM are periodically checked through onsite condition monitoring. Portable PD sets are used for PD scans at cable sealing ends of transformers, line reactors, and switchgears, and at allaccessible compartments in the switchgears. Ultrasonic scans are performed on electrical equipment to detect any electrical discharges resulting from ionisation due to arcing or corona. The scanners can detect high frequency signals resulting from electrical discharges, the sound of which lies outside the normal human hearing range. Ultrasonic scans are used for power and distribution transformers, line reactors, medium and high voltage switchgears. Cable sealing ends of transformers and switchgears, main tanks of transformers, and all accessible compartments of the switchgears are examined using ultrasonic scanners. In addition to PD scans and ultrasonic scans, thermal infrared scans are also carried out periodically on the abovementioned equipment to detect any potential hotspots. Some other condition monitoring tests are the SF6 gas quality checks in gas insulated switchgears and dissolved gas analysis (DGA) of insulating oil in transformers. These tests ascertain the dielectric strength of the insulating material and potentially warn of any contamination. SPPA’s preventive maintenance program covers all network equipment under operation including the auxiliary systems (e.g., DC chargers, batteries, etc.) in the substations. The regular maintenance program generally involves examination, testing, servicing, replacement of parts, checks on operating mechanisms and contacts, oil change, etc., as applicable. OEM maintenance manual is adhered to in executing the maintenance activities. Fig. 2 - Portable Partial Discharge Detection Devices 9 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS 2.2.2 Renewal program for network equipment The equipment renewal program for Singapore’s electricity network prioritises replacements based on factors such as equipment performance, condition, age and substation criticality. Performance-based renewal ensures that the unreliable assets are timely replaced to prevent failures. Condition-based renewal makes sure that the assets with high potential of failure are replaced before they fail. Age-based renewal of assets ascertains that aging assets are retired from service before they enter the phase of high failure probabilities. 2.2.3 Splitting of the transmission network Singapore’s electricity transmission network is presently divided into four blocks – North-East, North-West, South-East and South-West, with the highest transmission voltage being 400kV. Division of the network in multiple blocks minimises the impacts of the voltage dips to a large extent. The voltage dip due to a fault at 66kV and below in one block hardly propagates to the other blocks. Moreover, a fault at 230kV in one block would result in much lesser voltage dip magnitudes in the other blocks. The transmission planning team in SPPA forecasts demand and generation determine the need for further splits or reconfiguration of the network. 2.2.4 Prevention of cable damage To address concerns regarding voltage dips resulting from cable damage during excavation, SPPA conducts regular briefings for stakeholders such as contractors, developers, consultants, and excavation workers. Stringent procedures require contractors to engage licensed cable detection workers (LCDW) for site scanning and risk assessment before commencement of any excavation works. Trial holes are manually dug without any heavy machinery with reference to the cable plan drawing to confirm the Fig. 3 - Cable detection Work and Cable Tunnels presence of cables. SPPA ensures that the appointed registered excavator operator (REO) and registered earthwork supervisor (RES) undergo mandatory training to ensure competency. Furthermore, SPPA representatives patrol the excavation area regularly, conduct spot checks, and pay special attention to the excavation works in the vicinity of the HV cables. In addition, some 230kV and 400kV cables are laid in cable tunnels under parts of Singapore to protect them from damage during earthworks. 2.2.5 Power Quality Monitoring for Voltage Disturbance Management Whenever voltage disturbances occurred in the network, it is important that these disturbances are recorded for post fault analysis and effective network management. SPPA had setup a Power Quality Monitoring System to continuously monitor the Transmission and Distribution network’s power quality performance. 10 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS 2.3 Preventive Measures by Customers Customers play a pivotal role too within the grid network and share responsibility for maintaining power quality. This section highlights the importance of customers taking proactive measures to minimise equipment failures and ensure seamless operation of their facilities. 2.3.1 Regular Equipment Maintenance In accordance with the Electricity Act (Chap. 89A), customers are obligated to appoint a licensed electrical worker (LEW) of appropriate class to oversee electrical installations and conduct scheduled inspections of their electrical installations. Inspections occur at least once a year, with higher risk environments or premises undergoing more frequent checks. The appointed LEW assesses operating conditions, identify any wear and tear, and recommends suitable inspection frequencies, establish maintenance schedules, and additional measures based on their assessment. 2.3.2 Voltage Dip Management Recognising that voltage dips are inherent and unavoidable, customers must proactively manage these occurrences. A structured PDCA (Plan-Do-Check-Act) approach aids in systematic voltage dip management: ACT Review and Improve PLAN Risk Assessment PDCA (Plan-Do-Check-Act) CHECK Monitoring and Evaluation DO Implement Solution Fig 4 - Continuous improvement of Voltage Dip Management 11 >> CHAPTER 2: PREVENTIVE MEASURES AGAINST VOLTAGE DIPS Plan (Priority Setting and Risk Assessment): • Identify and prioritise critical processes and equipment that are most sensitive to voltage dips and have a significant impact on operations or safety. • Perform a thorough risk assessment for these prioritised processes and equipment to understand potential vulnerabilities and the potential consequences of voltage dips. • Define clear criteria for determining the urgency and severity of voltage dip mitigating efforts based on the outcome of the risk assessment. • Establish a strategy for collaboration with relevant stakeholders, including licensed electrical workers (LEWs) and Original Equipment Manufacturers (OEMs), to gather expertise and insights to implement appropriate mitigating solutions. Do (Implement Solutions for Voltage Dip Ride-Through): • Based on the prioritised list of critical processes and equipment, implement appropriate mitigating solutions (in Chapter 5) that enhance the ride-through capability during voltage dip events. These solutions may include Uninterruptible Power Supplies (UPS), Dynamic Rotary UPS (DRUPS), Voltage Dip Restorers, DC compensators, etc. • Ensure that the chosen solutions are adequately sized and configured to match the specific requirements of each prioritised process or piece of equipment. • Implement Business Continuity Management (BCM) and Recovery plans, including clear procedures for responding to voltage dip events and minimising downtime. • Train relevant personnel to operate and respond swiftly to voltage dip situations, ensuring that they understand the recovery plans when operations are affected. Check (Continuous Monitoring and Evaluation): • Continuously monitor the performance of the implemented mitigating solutions, and their effectiveness in providing voltage dip ride-through capability. • Regularly review the recorded data on voltage dip events, analyzing the impact on critical processes and equipment that were prioritised in the planning phase. • Compare the actual outcomes with the criteria established during the planning phase to determine if the implemented solutions are meeting the expected goals. • Conduct periodic reviews with LEWs, OEMs, and internal stakeholders to gather feedback on the effectiveness of the solutions and identify any emerging issues or areas for improvement. Act (Investigate, Review, and Improve): • Analyse the data collected during the Check phase to identify patterns, trends, or any incidents that indicate potential weaknesses or areas for enhancement. • Investigate the root causes of any deviations from expected outcomes or incidents related to voltage dips. • Based on the findings from the investigation, update and refine the risk assessment, prioritysetting criteria, and mitigating strategies as needed. • Implement any necessary changes or enhancements to the voltage dip management and recovery By adopting this proactive approach, customers with voltage-sensitive equipment can significantly enhance their ability to withstand voltage dips, minimise disruptions, and maintain business continuity. 12 CHAPTER 03 Power Quality Monitoring Different equipment exhibits varying tolerance levels and vulnerabilities to power quality, it malfunctions when power quality falls beyond their tolerances. Accurate data on power supply quality during such events is crucial for investigation. Consequently, it’s imperative for companies with voltage-sensitive facilities to establish permanent power monitoring systems at strategic points to detect supply abnormalities. 13 >> CHAPTER 3: POWER QUALITY MONITORING 3.1 Objectives of PQ Monitoring The following objectives underpin the rationale for procuring and implementing a Power Quality Monitoring System: 1. Continuous Monitoring and Evaluation: The need to continuously monitor and evaluate the supply system is driven towards identifying disturbances and variations in power quality that could potentially disrupt the seamless operation of the plant. By gathering data on these disturbance events, we not only enhance the resilience of existing equipment to withstand disruptions but also gain insights to finetune mitigating strategies and improve the ride-through capabilities. 2. Evaluation of Power Quality Characteristics: The data garnered through monitoring serves as a means to assess the power quality attributes of the equipment situated within the facility. This encompasses vital considerations such as the interaction between harmonics generated by loads and power conditioning equipment. Additionally, the study of in-rush characteristics, exemplified by compressor motors and similar loads, comes into play due to their potential influence on the operation of backup generators. The evaluation extends to voltage transients linked to switching events within the facility or the equipment’s response to voltage fluctuations originating either from the grid or internally. Over an extended period, the accumulation of monitoring data facilitates the early identification of supply quality issues, such as an undue escalation in harmonics levels, which could potentially impact other plant equipment if not addressed promptly. 3. Effective Energy Management: Beyond power quality parameters, the data obtained also encompasses energy-related information. This information becomes instrumental in efficiently governing and managing energy consumption within the facility. This dual-purpose approach not only contributes to cost savings but also aligns with efforts to curtail carbon emissions. For these purposes, a permanent Power Quality Monitoring System equipped with real-time online monitoring and reporting is essential. This system can process disturbances and steady-state power quality data, send alerts via SMS or email, and facilitate swift response when abnormalities occur. 14 >> CHAPTER 3: POWER QUALITY MONITORING 3.2 PQ Monitor Fundamental Within the vast market of power quality (PQ) monitors, both fixed and portable variants, the process of selecting a suitable monitor can be a daunting task, often entangled with challenges and confusion. In this section, we aim to explain the essential technical aspects to aid your selection process. Fig 5. - PQ Monitor Samples When selecting a PQ monitor, a pivotal criterion is the PQ measurement standards employed in calculating voltage disturbances and steady-state electrical parameters. PQ monitors adhering to internationally recognised standards, such as “IEC61000-4-30 on Testing and measurement techniques – Power quality measurement,” are strongly recommended. This standard is categorized into Class-A (with stringent requirements) and Class-S (for general PQ measurements with less stringent requirements). Users should opt for the relevant Class that aligns with their PQ measurement objectives. In instances of voltage dip and swell disturbances, Class-A monitors adopt Urms(½), while Class-S monitors can use either Urms(½) or Urms(1). (Fig 6 illustrate Urms(1) and Urms(½) measurement method). Fig 6 - Urms(1) and Urms(½) Calculation Methology A PQ monitor’s core function entails capturing voltage disturbances (Dip, Swell, and Transient) when they manifest, alongside continuous measurement of crucial steady-state parameters: voltage, current, frequency, harmonics (THD, orders, inter-harmonics), unbalance, flicker, power factor, energy, power, etc. The monitor also encompasses additional measurements (e.g., rapid voltage changes, superharmonics) that gain relevance in specific environments or conditions within the plant. Given the nearly universal claim of compliance with IEC61000-4-30, distinguishing between PQ monitors can be challenging. To gauge superiority or suitability, it’s crucial to understand the calculation of “Mean” steady- 15 >> CHAPTER 3: POWER QUALITY MONITORING state parameter values as stipulated by the standard. However, the calculation methodology for Minimum and Maximum values remains unspecified, varying across monitor manufacturers. Thus, comprehending how these values (e.g., voltage, current, frequency) are calculated is essential for discerning their practical significance. (Refer to Fig 7 for 24hrs Voltage RMS plot) Fig 7 – 24Hrs Voltage RMS Plot (Min/Mean/Max) In Fig 7 above, the 10-min Min and Max voltage was computed based on Urms(½) (eg. voltage RMS is calculated per cycle at “every zero-crossing”) as defined in IEC61000-4-30. Based on this measurement method, this implied that the RMS voltage over the 10-min measurement interval as highlighted in the box do not exceed 1.002pu and below 0.972pu for the Max and Min value. Another key aspect to take note during PQ monitor selection is the sampling rate. Some suppliers emphasise higher rates, like 512 samples/cycle compared to 128 samples/cycle counterparts. If both monitors complied to IEC61000-4-30 Class-A, then the voltage measurement accuracy is the same at 0.1% regardless of sampling rate. If the voltage in your operating environment is “relatively clean” and sinusoidal (Fig 8 bottom blue waveforms), there is no “significant” different when measuring at 128 or 256 samples/cycles. However, if the voltage is ”noisy with many spikes” or “rapid fluctuation” in voltage waveform (Fig 8 top red waveforms), then the waveform captured will be different and steady-state measured values between the two sampling rates will likely be slightly more “significant”. Hence, it is important to establish the specification requirements needed for your operating environment. Fig 8 – 128 and 256 samples/cycle waveforms 16 >> CHAPTER 3: POWER QUALITY MONITORING Another frequent question on PQ monitor’s specification is how much memory/storage size is required. For permanent PQ monitors connected to servers for regular data downloads, a storage size accommodating about one month of trending and disturbance data suffices. However, for a portable PQ monitor that is placed on-site for investigation without communication link to server, it requires a much larger storage size especially when numerous disturbances are anticipated. Hence, it’s prudent to consult vendors regarding memory storage needs for specific data intervals such as for a 1-week trending data at fixed time interval setting of e.g., 10mins, and waveform captures, e.g., 15 cycles (300ms) and 50 cycles (1-second) including both 3-phase voltage and current. When we know how much trending and disturbance data storage size are, then we can calculate the minimum memory storage size is needed example for 1-month of trending data and a minimum numbers of disturbance waveforms (e.g. 20 disturbance waveforms). Permanent PQ monitoring systems are essential for any voltage-sensitive facilities, enabling proactive identification and resolution of conditions that could jeopardise operations. The selection of monitoring locations depends on the facility design, critical loads, power conditioning equipment and the specific objectives of the monitoring. Minimally, PQ monitoring should be installed at the power supply intake from network and outputs of power conditioning equipment. For sites with redundant or backup supplies, monitoring each feed is advisable. More extensive monitoring could be carried out to include critical loads, such as clean room air-conditioning, critical tools, and communications equipment. For less critical points, Class-S monitors can be installed to optimise PQ measurement coverage. In medium to extra high voltage power system, there are only 3 phases and “NO” neutral conductor. The voltage transformers (VTs) used for metering are generally phase-phase or phase-neutral/earth type (Fig 9). When connecting PQ monitor voltage input configuration to Phase-neutral VTs, the choice lies between Star (phase-neutral) or Delta (phase-phase) voltage input setting. The Star configuration highlights the “faulted” phase/phases in captured disturbance waveforms and is useful for fault investigation. Since medium/high voltage customers are connected to SPPA via 3-conductor cables, voltage dip magnitudes shared by SPPA based on phase-phase are more applicable as experienced by customer’s LV equipment due to “delta-star” transformation to low voltage. Fig 9 – Type of Voltage Transformers Connection 17 >> CHAPTER 3: POWER QUALITY MONITORING It is important that the PQ Monitor software offered is user-friendly. It should facilitate navigation and allow user customisation and configuration of measurements based on site conditions. Features like zoom functions (preferably with x and y axis independently), panning, measurements between markers, exporting screen captures and exporting data to text files are useful to enhance viewing, analysis and reporting capabilities. Beyond collecting PQ data, the PQ software is an important tool for data viewing and analysis. Hence, the software flexibility and capability also need to be considered when evaluating the PQMS system. 3.3 Other PQ monitor features While most PQ monitors available in the market proficiently capture voltage and current based on voltage threshold configurations, situations necessitating the investigation of transformer or motor in-rush or starting current episodes warrant a different approach. Here, the utilisation of current threshold settings for waveform recording becomes essential to ensure the consistent capture of in-rush current waveforms when the need arises. Fig 10 – Voltage and Current RMS Threshold Setting Another useful feature is “High-Speed” (HS) transient module to capture “high” frequency transient waveform (especially in low voltage (LV) network investigation). It’s worth noting that some monitors excel in High- Speed “detection” yet lack the ability to capture and record the waveform for subsequent analysis. There are many different HS transient modules available in the market, boasting sampling rates spanning from a few hundred Kilohertz (KHz) to tens of Megahertz (MHz),with the majority falling within the 1MHz and below range. 18 >> CHAPTER 3: POWER QUALITY MONITORING In Fig 11 below, the transient waveform frequency is about 600KHz as captured at 5MHz sampling rate. It’s important to recognize that employing a 1MHz HS module yields a fundamentally “different” captured waveform due to the incredibly short 1µs sampling interval, despite the actual duration of the one-cycle transient waveform being 1.8µs. However, this HS feature generally has limited application when monitoring the secondary side voltage of a medium or high voltage transformer (VT) due to VT’s frequency respond characteristic. Fig 11 – High-Speed Transient Voltage Waveform @5MHz 3.4 Other benefits of PQ monitoring After a PQ monitor recorded a voltage dip disturbance, one of the most common and often asked question pertains to determining the fault’s point of origin – whether it stemmed from upstream or downstream of the monitoring location. If the recorded current reading reflects a “significant” increase in magnitude, it is implied that the fault originated downstream of the measurement point. Conversely, the absence of a significant increase in current magnitude during the fault implied that the disturbance originated from upstream of the measurement point. (Refer to Fig 9 below for illustration). Fig 12 – Determine direction of fault based on current waveform 19 CHAPTER 04 Voltage Dip Mitigating Techniques This chapter provides the overview of the various voltage dip mitigating options and techniques that can be implemented at different level depending on customers risk appetite to minimise the impact of voltage dips. It is paramount to understand that when implementing any voltage dip mitigating solution, the solution can only protect against disturbances originated upstream, but it cannot mitigate against downstream disturbances. 20 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES 4.1 Voltage Dip Mitigating Options depending on Risk Appetite While voltage dip is unavoidable, its adverse effects can be mitigated through the deployment of solutions designed to counteract voltage dips. In this way, even if the supply voltage momentarily plummets, continuity of voltage supply to equipment or processes remains unscathed. Fig 13: Voltage Dip Mitigating Solutions at various Options level In the following sections (4.2 to 4.6), a more in-depth explanation will be provided on the type of voltage dip mitigating solutions at various options level. These solutions are tailored in accordance to the voltage sensitivity of the equipment and its criticality of operations. Furthermore, the level of mitigating solution pursued acts as a direct indicator of the identification of pivotal buildings, assembly lines, or equipment warranting voltage dip mitigating interventions. 21 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES 4.2 Option 1: Protection through Equipment Specification At Option 1 level, the focus shifts to the identification of voltage-sensitive equipment. During the procurement phase, voltage dip mitigating solutions are integrated into equipment specifications. Customers can specify upfront that the ride-through performance requirement to be compliant with reference to an industry standard, guidelines (e.g. SEMI F47, ITIC, IEC61000-4-34) or tailored to their specific requirements (eg. Samsung Power Vaccine). The important point here is that the required equipment immunity to power quality variations should be specified upfront and addressed at an early stage. Determining the requisite equipment immunity involves leveraging historical voltage dip records as shown in Fig 14. By understanding the various ride-through performance standards and checking against the past voltage dips statistics, it will help make an informed decision on which standard to specify to the OEM for those voltage sensitive equipment. Fig 14: Voltage Dip Records from 2020 to 2023 Voltage dip ride-through performance charts are used to show the capability of electrical equipment to withstand voltage dips. Different standards and specifications define the criteria for voltage dip ride-through performance. We delve into each of the specified standards and guidelines, exploring their respective voltage dip ride-through performance charts. 22 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES 4.2.1 SEMI-F47 SEMI is a global industry association that develops standards for the semiconductor manufacturing industry. Established in 1999, the SEMI F47 standard specifies the requirements for voltage dip immunity for semiconductor manufacturing equipment, with subsequent revisions, including the latest in 2004. The standard delineates permissible voltage dip depth and duration, ensuring equipment sustains uninterrupted operation. Due to its cost-effectiveness, this standard has since been widely adopted for non-semiconductor industry as well. In the Fig 15, the red line represents the SEMI 47’s voltage dip ride-through performance line, and the green highlighted zone shows the protection zone, indicating the acceptable operating region where the equipment can continue to function without disruptions during voltage dips. Based on the past voltage dips records, it was observed that there were 2 voltage dip incidents (highlighted in yellow), which are below the SEMI F47 ride-through curve. It’s worth noting that compliance with the SEMI F47 requirement does not ride through all voltage dips. Fig 15: SEMI F47 Voltage Dip Ride Through Performance Line 4.2.2 ITIC (CBEMA) Originating in the 1970s, the Computer Business Equipment Manufacturers Association (CBEMA) developed the CBEMA curve as a guideline for the power supply design. The main application was to describe the tolerance of mainframe computer business equipment to the magnitude and duration of voltage variations on the power systems. As the computer equipment start to evolve over the years, the Information Technology Industry Council (ITIC) was formed in 1994 to derive a curve as shown in Fig 16, accounting for the performance of single-phase, 120 V, 60 Hz computers and related technology peripherals. The latest revised ITIC curve was in 2000 and it now applies broadly to general power quality evaluation and various loads and devices containing solid-state components. Figure 16: ITIC (CBEMA) Curve 23 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES In particular to voltage dips events, the lower ITIC curve up to the “No-damage region” serve as a reference for specifying the ride-through requirement of the voltage sensitive equipment as shown in Figure 17. “No-damage region” specify conditions where voltage dip might occur but shouldn’t result in equipment damage. Based on the past voltage dips records, it was observed that there were 3 voltage dip incidents (highlighted in yellow) below the ITIC ride through curve. This underscores that even adherence to ITIC ride-through requirements does not ride through all voltage dips. Figure 17: ITIC Voltage Dip Ride Through Performance Line 4.2.3 IEC 61000 4-34 IEC 61000-4-34, a component of the International Electrotechnical Commission (IEC) 61000 series, serves as a comprehensive framework for electromagnetic compatibility (EMC) testing and standards. The most recent iteration, published in 2009, focuses on evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions, and voltage variations. For voltage dips events, IEC 61000-4-34 prescribed recommended test levels as illustrated in Fig 18 for the equipment in different electromagnetic environment classes, which is specified in IEC61000 2-4 (Annex B). It shows the voltage dip % magnitude and duration in cycles applied to the equipment to assess its immunity to such events to verify its compliance to the IEC 61000-4-34. Fig 18: Preferred test level and durations for voltage dips 24 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES Fig 19 shows the performance ride-through lines for the IEC 61000-4-34 Class 2 and Class 3. The protection zone, denoted in blue, corresponds to the IEC 61000-4-34 Class 3 standard. Notably, despite compliance with IEC 61000-4-32 Class 3 requirements, analysis of past voltage dip instances reveals an occurrence (highlighted in yellow) that remains below the stipulated standard. Thus, it is apparent that even adherence to IEC 61000-4-34 Class 3 specifications does not ride through all voltage dips. Figure 19: IEC 61000-4-34 Voltage Ride Through Performance Line 4.2.4 Samsung Power Vaccine The concept of “Power Vaccine” immunity levels was innovated by Samsung Semiconductor. Hence, the name “Samsung Power Vaccine”. Equipment adhering to the Samsung Power Vaccine specifications must be able to sustain uninterrupted operation, even when subjected to a 100% voltage dip magnitude up to 1 second. It’s important to note that its stringent requirement as compared to the other voltage dip ride-through performance standards, might potentially necessitate higher implementation costs due to the need for more energy storage to withstand the deeper voltage dips and endured over longer periods. Fig 20 shows the performance ride through line for the Samsung Power Vaccine. The protection zone, highlighted in orange, pertains to equipment aligning with the Samsung Power Vaccine. Based on the past voltage dips records, it is evident that if equipment conforms to the Samsung Power Vaccine requirements, its operation will not be affected at all. Fig 20: Samsung Power Vaccine Voltage Ride Through Performance Line 25 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES Overall, when adopting Option 1 which involves specifying the voltage dip ride-through performance for the voltage sensitive equipment, implemented during the procurement phase can be a seamless and cost-effective approach, as customers do not need to install external voltage dip devices. Understanding the various voltage dip ride performance requirement and analysing past voltage dip statistics will help to make better informed decision on which standard or guideline to follow. However, for existing equipment that were not originally mandated to adhere to any voltage dip ride-through performance standards, there are external voltage dip mitigating solutions available in the market to fortify equipment resilience and bring them in line with these requirements, as elaborated in subsequent sections. Where customer’s risk appetite is not able to tolerate any voltage dips, which are beyond any option 1 voltage dip ride-through protection zone, option 2 or above mitigating solutions will be required. 4.3 Option 2: Protection at Equipment level For Option 2, the mitigating solution is implemented at the incoming supply to the identified voltage sensitive equipment. Seeking advice from voltage dip mitigation providers is advisable to achieve the optimal solution for the voltage sensitive equipment. This category of voltage dip mitigating solutions includes static Uninterruptible Power Supplies (UPS), voltage dip restorers (eg. MiniDYSC) or DC Compensators. In various motor soft-starter applications, the Variable Speed Drive (VSD) is a prevalent choice due to its ability to effectively regulate the speed and torque of an electric motor by adjusting the frequency and voltage supply. However, it has been noted that in the event of a voltage dip, the VSD can become vulnerable points systems like chiller operations if they are not adequately protected or hardened against voltage dips. An example of a voltage dip mitigating device that is suitable to harden such equipment is the DC Compensator, which is installed at the DC link of the VSD. A DC Compensator grounded in power electronics-based functions to counterbalance the power loss due to voltage dip by compensating for voltage drops in the VSD’s DC link. The key components of a DC compensator are a charger, an energy storage (typically a capacitor bank) and the ride-through voltage regulator. Fig 21: Example of Option 2 voltage dip mitigating solution: DC Compensator During normal operation where the voltage supply to the VSD remains stable, the charger of the DC compensator continuously monitors the incoming AC voltage, ensuring it remains within acceptable thresholds and sustaining the capacitor bank’s charge. 26 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES In the event a voltage dip occurs in the AC supply, the ride-through voltage regulator of the DC compensator promptly detects the voltage drop and triggers the discharge process of the capacitor bank. Depending on the extent of the voltage drop, the capacitor bank rapidly releases its stored energy through power electronic switches, converting it into DC voltage. This DC voltage harnessed to offset the voltage drop in the VSD’s DC link. This compensation mechanism effectively maintains a relatively stable voltage in the VSD’s DC link during the voltage dip. As a result, the VSD is empowered to deliver an uninterrupted supply of adequate voltage or frequency to the connected motor, enabling seamless motor operation at the desired speed without being impacted by the voltage dip. The DC compensator offers varied energy storage options such as ultracapacitors, capacitor banks and batteries. Under the ultracapacitor option, in scenarios where voltage dip leaves 40% remaining voltage (a 60% dip), the compensator can restore the voltage back to nominal levels for up to 2 seconds. In instances of 0% remaining voltage (100% dip), it can compensate for the voltage drop for up to 0.5 seconds. For comprehensive protection against complete outage and prolonged voltage dips (up to 1 minute), battery-based energy storage becomes the preferred choice as it can compensate up to 15 minutes full outage. However, this option will be the most costly and additional space is required to store the batteries. Overall, a DC compensator with ultracapacitor emerges as a cost-effective solution in maintaining stable voltage levels in variable speed drives during voltage dips. This contributes to the reliability and performance of the connected motors and its associated systems. Notably, its smaller footprint, relative to Dynamic Sag Corrector (DYSC), due to the absence of DC to AC converter and ease of installation, marks an advantage. Its parallel installation to the VSD facilitates implantation without disrupting ongoing operations and its ultracapacitor system is sufficient to compensate for the full voltage loss for up to 0.5 seconds during severe voltage dip incidents. 4.4 Option 3: Protection at Process/Line level Option 3 entails the implementation of the mitigating solution at the process or line supply level, typically at the LV subswitchboard. This approach targets the critical process or line of the manufacturing operation, as well as the points where voltage-sensitive equipment are connected. This category of voltage dip mitigating solutions includes static Uninterruptible Power Supplies (UPS) or voltage dip restorer (e.g., ProDYSC). An example of a voltage dip mitigating device for deployment at the LV sub-distribution panel is the Dynamic Sag Corrector (DYSC). The DYSC is a power electronics-based device, generally leverages the unaffected healthy phase of the voltage during voltage dips, or alternatively employs an extended energy storage system, often capacitors for longer interruption, to compensate for the power loss to the loads during the voltage dip incidents. The key components of a DYSC include the controller, static switch, power electronics converter and the option for an extended energy storage system. Figure 22: Example of Option 3 voltage dip mitigatingn solution: DYSC 27 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES During stable voltage supply, the DYSC continuously monitors the voltage waveform at its input through the voltage sensor in the controller. When the input voltage is within the acceptable range, the DYSC operates through the static switch mode, allowing voltage to pass through without compensation. When the DYSC detects a voltage dip below a predetermined threshold, the voltage sensor control circuit initiates corrective action. The power electronics converter, which consists of thyristors or IGBTs, will switch into position and starts injecting electrical energy from unaffected voltage phase or from the extended energy storage system (if present). This energy is then supplied to the loads. The controller ensures precise timing and synchronization of voltage correction with the voltage dip, thus minimising the impact on connected equipment. Once the voltage dip event has passed, and input voltage returns to the acceptable range, the DYSC reverts to the static switch mode, allowing unimpeded power flow. The DYSC offers both standard and extended capacity option. Under the standard option, it can compensate for voltage drops from 87% to 50% remaining voltage, restoring voltage to nominal levels up to 5 seconds during voltage dip incidents. For instances of 0% remaining voltage (a 100% dip), compensation can extend up to 50ms for standard capacity and 200ms for the extended capacity option. It is important to note that even with the extended energy storage, there is a limit to the duration of dip it can compensate. Hence if it is deemed necessary to protect against severe and long voltage dip duration (>50% dip and > 200ms dip duration), statis UPS maybe the suitable option. Overall, the DYSC proves to be a valuable asset in modern power distribution systems, offering dynamic and swift responses to voltage dips. This ensures the seamless operation of sensitive equipment and preventing potential damage or disruptions caused by these temporary voltage drops. Key advantages include its compact footprint and independence from battery-based energy storage to compensate for power loss during voltage dip occurrences. Depending on the load capacity requirements, MegaDYSC rating can be rated up to 1.6MVA (3Phase,400V), ProDYSC up to 140kW (3Phase, 400V) and MiniDYSC up to 12KW (Single phase, 240V). By selecting the appropriate DYSC rating, it can also serve as a voltage dip mitigation solution for LV main switchboards (Option 4) or even down to equipment-level applications (Option 2) 4.5 Option 4: Protection at Building level For option 4, the solution can only protect against disturbances originated upstream of the building premises. It cannot mitigate against downstream disturbances within the building premises. Option 4 involves implementing the mitigating solution at the building level, typically at the LV main switchboard. This strategy targets critical operations within the entire plants or the points where voltage-sensitive equipment is connected. Voltage dip mitigating solutions at this level include static Uninterruptible Power Supplies UPS, rotary UPS (flywheel) or Dynamic Voltage Restorer (MegaDYSC). An example of a voltage dip mitigating device that can be installed at the LV main distribution panel is the Static UPS. It uses batteries as an energy storage to provide backup power to electrical equipment during power outages or grid network fluctuations. Key components of a static UPS include batteries, an inverter, and UPS, consisting of the rectifier, charging, and monitoring system. The UPS continuously monitors incoming power supply from the grid network for any voltage or frequency irregularities When the grid network delivers stable power within the acceptable voltage and frequency ranges, the UPS permits power to flow directly through to the connected equipment without intervention. Upon detecting a dip or interruption in the grid power supply, such as a voltage drop or an outage, the UPS immediately activates its internal battery system, which remains charged and prepared to provide backup power when needed. The UPS seamlessly switches the power source from the grid to the battery-powered inverter, typically within milliseconds, to 28 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES avoid any interruption to the connected equipment. The UPS supplies power to the connected equipment from its battery system, compensating for the power dip or outage in the grid network. The backup power enables equipment to continue operating without disruption, safeguarding against data loss, equipment damage, or downtime. Once the grid power stabilizes or returns, the UPS detects the improvement and seamlessly switches the power source back to the grid supply, once again to avoid any interruption. While operating on the grid power, the UPS simultaneously recharges its internal batteries to ensure that the batteries are ready for the next power dip or outage. Overall, a static UPS acts as a buffer between the grid power supply and the connected equipment, providing continuous and reliable power during power dips or outages. When sized appropriately, it ensures the smooth operation of critical equipment and protects against any voltage disturbance including interruptions. When coupled with a step-up transformer and appropriately sized for sensitive loads, it can also be used as a voltage dip mitigation at the MV main switchboard (option 5 level). Fig 23 - Example of Option 4 voltage dip mitigation solution: Static UPS with battery 4.5 Option 5: Protection at Plant level Similarly for option 5, the solution can only protect against disturbances originated upstream of the plant network. It cannot mitigate against downstream disturbances within the plant network. In Option 5, the voltage dip mitigating solution is implemented at the high voltage (HV) supply intake level to the entire plant as shown in Fig 24. This approach typically overprotects the plant, protecting both sensitive and non-sensitive loads. HV devices can be expensive due to the high component cost of HV equipment such as the HV switchgear and transformers. Another consideration would be the footprint requirement of these devices, which can be substantial. Nevertheless, this solution offers a one-off connection. Importantly, the solution protects against voltage dips originating from the supply network but not from those occurring within the plant network. Such voltage dip mitigating solutions include Rotary (Flywheel) UPS, Static (Battery) UPS or Dynamic Rotary (Flywheel with diesel engine) UPS. An example of voltage dip mitigating solution installed at the HV (e.g. 22kV) main switchboard is the Rotary Uninterruptible Power Supply (UPS). This system combines mechanical and electrical components to provide continuous and reliable power to critical loads when a voltage dip occurs. The key component of a rotary UPS is a high-speed flywheel, which acts as an energy storage device. The flywheel is connected to an electric motor/generator set, commonly known as a motor-generator (MG) set. 29 >> CHAPTER 4: VOLTAGE DIP MITIGATING TECHNIQUES During normal operation when the utility voltage supply is stable, the motor-generator set operates as a motor. It draws electrical energy from the grid and converts it into mechanical energy to spin the flywheel at high speeds. As the flywheel rotates, it stores kinetic energy. In the event of a voltage dip from the grid, the flywheel takes over as the primary source of energy. It releases the stored kinetic energy which is converted back into electrical energy by the motor-generator set, now operating as a generator. As the flywheel slows down, it releases the stored energy, allowing the generator to produce electricity. This energy conversion process is rapid, typically within a few milliseconds, allowing the critical load to receive continuous power without interruption. The rotational energy of the flywheel bridges the gap between the loss of utility power and the startup and stabilisation time of an alternative power source, such as a diesel generator. The rotary UPS system also incorporates power electronics, such as inverters and rectifiers, to regulate the voltage, frequency, and waveform of the electrical output, ensuring compatibility with the critical load’s requirements. Overall, a rotary UPS provides reliable power backup by utilising kinetic energy stored in a high-speed flywheel, enabling it to compensate for power loss or voltage fluctuations from the grid network. Fig 24: Example of Option 5 voltage dip mitigating solution: Rotary UPS (RUPS) with Flywheel 30 CHAPTER 05 Voltage Dip Case Studies 31 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES Case Study 1: Chillers In this case study, we examine the impact of voltage dips on chiller operations. Chillers are one of the most common equipment used in all industries from commercial buildings to manufacturing plants. The chiller system consists of compressor, condenser and cooler with motors that are controlled by voltage-sensitive variable speed drives It plays a crucial role in various industries, providing chilled air and water for critical processes. Any interruption in chiller operation due to voltage dips can disrupt plant operations, leading to the loss of process cooling water. In high-tech industries like semiconductors and data centers, uninterrupted chiller operation is vital. In data center operations, chiller stoppage can result in a rapid rise in temperature within server racks, eventually causing server shutdowns and related issues. The customer faced an issue where their chiller tripped and stopped during a voltage dip incident. Investigation revealed that the failure might have been caused by relay dropouts in the control circuit of the chiller system during voltage dip. Relays were commonly used for the starters of the condenser pump motors. Additionally, it was noted that the control board in the microcomputer also had an auxiliary relay, which potentially be a weak point when the voltage dip occurred. The customer requested SPPA to conduct voltage dip tests on their chiller’s control circuit together, including the microprocessor in the circuit. It was discovered that the relay contacts operated when voltage dipped by about 30%, leading to the motor’s tripping. After identifying the chiller’s control circuit’s vulnerability to voltage dip, the customer decided to install a voltage dip mitigating device for the control circuit to evaluate its effectiveness. Subsequent voltage dip tests were conducted at various dip magnitudes and durations, demonstrating that the installed dip mitigating device effectively protected the control circuit from tripping. It successfully rode through dip tests according to SEMI F47 which met customer’s requirement. (Note: Implementation of SEMI F47 guidelines does not assure full immunity against all disturbances. For more stringent dip ride through requirements, customer may consider higher guideline like Samsung Power Vaccine or customized guidelines.). Fig 25 – Voltage Dip Testing – Supply/Load Voltage and Current Waveforms 32 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES Case Study 2: Exhaust Air Fans Exhaust air fans (EAF) are commonly used in many high-tech manufacturing plants, particularly in controlled indoor environments or clean rooms. These fans must operate continuously to maintain the controlled environment within the clean room. Typically, these fans are usually driven by Variable Speed Drives (VSDs) to provide optimal airflow, soft starting and precise speed control. A customer noticed that the air pressure monitored by the EAF’s sensor fell below specified levels during voltage dip incidents. According to the operation requirements, the air pressure within the EAF should not drop to zero because doing so would compromise air quality in the controlled clean room environment, necessitating the disposal of affected products. During voltage dip incidents, the VSD would “trip” and cause the exhaust air fan to slow down and stop. Subsequently, the exhaust air-pressure sensor would trigger an alarm after detecting zero pressure. Although the VSD was configured to restart automatically after the fan had stopped, this still resulted in the problematic zero air pressure situation, leading to products scrapping. Voltage dip tests were conducted jointly with the customer to explore mitigating solution for the VSD to prevent this zero air pressure scenario. Fig 26 – Air Pressure of Exhaust Air Fan During voltage dips tests, the EAF air pressure was monitored using the plant’s Facility Management Control System. When the VSD was set to auto-restart, it was observed that the monitored air pressure dropped to zero. The customer consulted the VSD supplier, who suggested changing the VSD setting from auto-restart to a “flying” restart. With this adjustment, the VSD would rapidly increase the fan’s speed to normal before it came to a complete stop during the voltage dip. During subsequent voltage dip test with the VSD set to “flying” restart, the air pressure sensor recorded pressure drops, but the pressure did not drop to zero and production is not affected. Since the VSD had this “flying” restart built-in, the customer decided to enable this function as a mitigating measure against voltage dip incidents. The customer was highly satisfied with this dip mitigating solution as it incurred minimum costs and effectively prevented production losses. 33 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES Case Study 3: Flywheel UPS Many customers use flywheel Uninterruptible Power Supply (UPS) to protect their voltage sensitive equipment from voltage dip disturbances that could disrupt plant operations. However, in one case, a customer faced an unexpected issue where the entire plant’s supply was disrupted when all their flywheel UPS units were activated, despite no observable voltage drip disturbances during this activation. Intriguingly, there was a minor voltage drop of about 3% during this incident. This incident puzzled us as we were aware that the customer’s plant is equipped with multiple voltage dip mitigating devices that have successfully handled more severe drops, some as low as 7-8%. During investigation with the customer, it was revealed that the flywheel UPS units were activated due to frequency threshold violation. These frequency thresholds were set at ±1% (49.50hz and 50.5hz) by their OEM during commissioning of the UPS units. The customer explained that all the flywheel UPS were intermittently cutting in and out over a short duration, and when their stored energy was depleted, the plant was left without power because the flywheel UPS units had earlier disconnected the grid’s incoming circuits when they were activated. Although the voltage fluctuation was relatively small, the system frequency had indeed dropped below 49.50hz and the disturbance originated from a power generation plant. Upon further discussion, it became clear that the customer’s equipment was not sensitive to frequency fluctuations. Consequently, the customer was advised to either “disable the frequency threshold setting (if possible) or “de-sensitise” it by adjusting it to a higher, less restrictive value. This change would prevent the flywheel UPS units from activating unnecessarily due to minor frequency variations and avoid disruptions caused by frequency threshold violations. Fig 27 – Voltage RMS and Frequency Plot 34 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES Case Study 4: Under/Over Voltage Relay In this case, a customer reported a significant disturbance in half of their plant due to a voltage dip event, which coincided with a single-phase cable fault occurring on the same distribution network to which the customer was connected. The customer shared that their equipment recorded a “very high” voltage swell and a “severe” voltage dip during this incident. The root of the issue lay in the customer’s electrical setup, specifically the presence of Neutral-Resistor- Ground (NGR) connection installed at the transformer star point. In the event of a single-phase fault, such as the cable fault mentioned, fault current flows through the NGR, causing the two healthy phases voltages to “swell” at the neutral-star point. However, this process doesn’t lead to significant fluctuations in line voltages, with variations typically remaining below 10%. (Fig 28 for phase and line voltage disturbance waveform). The problem arose from the under/over voltage relay, which had activated during the event, resulting in an outage for half of the plant. The suspicion was that the customer’s voltage relay setting was based on phase voltage, as the recorded voltage disturbance magnitude closely matched the phase voltage values captured by SPPA. This misalignment occurred because the customer’s distribution transformers are “Delta- Star” configuration, where the LV supply did not experience voltage “swell/dip” for this single-phase fault, as the transformer primary voltages are Line-Line. Fig 28 – Phase and Line Voltage Waveform of A Single-phase Fault 35 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES To address this issue, the customer was advised to consult with their electrical plant designer to determine the correct relay settings. Additionally, it was recommended that for over/under voltage relay protection schemes at customer’s installation, the relays should be placed as close to the equipment or processes they are intended to protect. This would minimise unnecessary disruptions to other equipment. If the relays needed to be installed at the incoming feeders or main incoming switchboard, the relay’s magnitude and duration settings should be configured based on ”back-up” value, considering more serious dip magnitudes and longer durations. This adjustment would ensure that downstream protection relays had sufficient time to operate in the event of a disturbance. Fig 29 – Example of a ABB Over/Under Voltage Relay Photo and Connection Diagram 36 >> CHAPTER 5: VOLTAGE DIP CASE STUDIES Case Study 5: Other observations and suggestions a) Intelligent Drive Restart Planning in Plants Enable “Auto-Restart” and “Flying-Restart” of Multiple Drives in a Plant Customer considering implementing “auto” or “flying” restart for their drives in their plant should be aware of the potential issues that can arise. For example, enabling all their drives to “flying” restart simultaneously after a voltage dip incident might result in a collective in-rush current surge that can overload the upstream breaker at the sub or main distribution switchboard and cause it to trip. Once the “in-rush” characteristic is understood, a strategic plan can be developed to configure the drives to “flying” restart, “auto” restart and manual restart setting. For those drives that are configured to “auto” restart, it is crucial to implement a “delayed staggering” timing approach. This means that some drives will restart immediately after the incident, while others restart at a short delay, such as 5 minutes ,and still others after a longer delay, like 10 minutes. This staggered approach helps prevent over-current conditions and breaker tripping. b) Replace faulty protection part with the correct type and characteristics A customer reported an issue with one of the escalators stopping during a voltage dip incident, while the others remained unaffected. Investigation revealed that the escalator’s Miniature Circuit Breaker (MCB) has tripped due to overcurrent. Further investigation reviewed that although the MCB rating was the same as those used in other escalators, the MCB that tripped was the “incorrect” type, labelled as “Type-B”. In contrast, the MCBs in the other escalators were “Type-C”. Type-B MCBs are designed to trip at fault currents of 3-5 times rated current (In), while Type-C MCBs are designed to trip at 5-10 timesrated current (In). It was discovered that the maintenance crew had previously replaced the MCB with the “incorrect” Type-B when it failed. This case highlights the importance of training and reminding maintenance staff to use the correct type of characteristics of protection devices when replacements are necessary. Using the wrong type of protection device can lead to unexpected interruptions in the equipment operation during voltage disturbances.

Centrehttps://www.spgroup.com.sg/about-us/media-resources/news-and-media-releases/SP-Group-Opens-Singapore-s-First-Smart-Energy-Town-Showcase-at-MyTengah-Experience-Centre News Release SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centre Singapore, 19 October 2020 – SP Group’s (SP) MyTengah Experience Centre, an interactive showcase of SP’s smart energy solutions that will be deployed in Singapore’s first smart energy town at Tengah, will be open to the public from 20 October 2020. SP will bring Singapore’s first large-scale residential centralised cooling system to Tengah. Located at the HDB Hub in Toa Payoh, the MyTengah Experience Centre will give future Tengah residents and visitors a first-hand look and feel of living in the A.I.-enabled, eco-friendly, smart energy town. It provides visitors with an immersive experience of the benefits of the smart energy innovations that will be installed and integrated across more than 20,000 residential, commercial and community facilities. These innovations include the centralised cooling system, digital display boards of energy consumption at residents’ blocks, charging stations for electric vehicles, and a digital platform that enables a near real-time monitoring of these solutions. Mr Stanley Huang, Group Chief Executive Officer of SP Group said, “SP wants to create a lowcarbon, smart energy Singapore. Tengah will be the model for low-carbon smart energy towns in Singapore. The MyTengah Experience Centre brings to life the benefits that residents will enjoy with our smart energy solutions, which will enable residents to integrate sustainability into their everyday lives.” Residential Centralised Cooling In collaboration with the Housing & Development Board (HDB), SP will bring Singapore’s first largescale residential centralised cooling system1 to Tengah. Air-conditioning accounts for a quarter of an average Singaporean household’s electricity consumption2 . With SP’s centralised cooling system, Tengah residents can enjoy as much as 30 per cent energy savings. Chilled water will be centrally produced from interconnected modular chiller plants built on the HDB roof tops before it is distributed to residential and commercial units for air-conditioning. To maximise the limited space available in Tengah, SP is also testing both conventional and vertical solar panels, known as Building Integrated Photovoltaics (BIPV). The solar energy generated from these sources will then be used to power the centralised cooling system to meet the township’s cooling needs. The centralised cooling system will also be serviced by SP, bringing greater convenience to the Tengah residents. Smart Energy Solutions In addition to centralised cooling system, SP will be installing other smart energy solutions across Tengah. These include digital sustainability displays called Eco Boards at the housing blocks’ lift lobbies to drive community awareness and help residents be more mindful of their block’s utilities’ consumption and impact on the environment. These boards will also provide residents with green tips to lower their electricity and water consumption and promote sustainable behaviour through utilities-savings competitions between blocks. SP will also be implementing EV charging solutions in Tengah, with both fast and overnight chargers augmented by renewables and energy storage systems. At Tengah’s neighbourhood centre, drivers will be able to charge their EVs quickly at SP’s innovative Fast-Charging Hubs while attending to their errands. Digital Platform SP Group is rolling out OneTengah, a digital platform which integrates all the capabilities such as centralised cooling, battery energy storage systems, EV-charging stations, as well as data and analytics from other platforms within Tengah. The OneTengah platform will enable town council and facility operators to make use of energy management control and A.I.-enabled insights to monitor the town’s energy resources. They will also have complete visibility of systems in Tengah at an aggregated town or block cluster level. On a single dashboard, they can better monitor system performance and be alerted of anomalies, for quick actions to be taken to enhance the experience of living and working in Tengah. SP has also created a sustainable lifestyle app called myTengah app for an eco-friendly and hasslefree lifestyle. With the app, Tengah residents can access their household utilities consumption, intelligently control their centralised cooling usage, make smart decisions to lower their carbon footprint and integrate sustainability into their everyday lives. To visit the Tengah Experience Centre, simply walk in and register on site or make an appointment3 via the myTengah app, which can be downloaded on both the Apple App and Google Play stores. For more information on Tengah, please visit mytengah.sg. -Ends- Annex Testimonials from Future Tengah Residents “Initially, I was uncertain about centralised cooling because it is a new concept and I did not fully understand how it works. An SP Sustainability Ambassador personally and patiently explained to me how it works, with chilled water that is generated from highly energy-efficient modular chiller plants. SP Group then invited me for a sneak preview of the MyTengah Experience Centre. I saw the actual CCS chilled water indoor unit and was able to see how it will look like exactly in my future home, including the actual piping and fittings. I am now convinced and looking forward to saving more money in the long run.” - Mr Steven Ang, 64, future resident who signed up for centralised cooling for his new Tengah home “The MyTengah Experience Centre is such a cool and exciting place. It’s impressive and the fact that we can experience augmented reality elements, it’s the highlight for me as it showcases the intricate details and helps me visualise what has been planned for Tengah.” - Ms Beverly Tan, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah “Sustainability to me is the harmonious co-existence of man and nature. It is about achieving an equilibrium and balance. The MyTengah Experience Centre showcases the solution that can make this happen. To me, it’s also about savings and with CCS, we can save up to 30 per cent in our energy consumption. It is so economical.” - Mr Shaun Wong, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah About SP Group SP Group is a leading utilities group in the Asia Pacific, driving a low-carbon, smart energy future for its customers.

SP will bring Singapore’s first large-scale residential centralised cooling system to Tengah. Located at the HDB Hub in Toa Payoh, the MyTengah Experience Centre will give future Tengah residents and visitors a first-hand look and feel of living in the A.I.-enabled, eco-friendly, smart energy town. It provides visitors with an immersive experience of the benefits of the smart energy innovations that will be installed and integrated across more than 20,000 residential, commercial and community facilities. These innovations include the centralised cooling system, digital display boards of energy consumption at residents’ blocks, charging stations for electric vehicles, and a digital platform that enables a near real-time monitoring of these solutions. Mr Stanley Huang, Group Chief Executive Officer of SP Group said, “SP wants to create a lowcarbon, smart energy Singapore. Tengah will be the model for low-carbon smart energy towns in Singapore. The MyTengah Experience Centre brings to life the benefits that residents will enjoy with our smart energy solutions, which will enable residents to integrate sustainability into their everyday lives.” Residential Centralised Cooling In collaboration with the Housing & Development Board (HDB), SP will bring Singapore’s first largescale residential centralised cooling system1 to Tengah. Air-conditioning accounts for a quarter of an average Singaporean household’s electricity consumption2 . With SP’s centralised cooling system, Tengah residents can enjoy as much as 30 per cent energy savings. Chilled water will be centrally produced from interconnected modular chiller plants built on the HDB roof tops before it is distributed to residential and commercial units for air-conditioning. To maximise the limited space available in Tengah, SP is also testing both conventional and vertical solar panels, known as Building Integrated Photovoltaics (BIPV). The solar energy generated from these sources will then be used to power the centralised cooling system to meet the township’s cooling needs. The centralised cooling system will also be serviced by SP, bringing greater convenience to the Tengah residents. Smart Energy Solutions In addition to centralised cooling system, SP will be installing other smart energy solutions across Tengah. These include digital sustainability displays called Eco Boards at the housing blocks’ lift lobbies to drive community awareness and help residents be more mindful of their block’s utilities’ consumption and impact on the environment. These boards will also provide residents with green tips to lower their electricity and water consumption and promote sustainable behaviour through utilities-savings competitions between blocks. SP will also be implementing EV charging solutions in Tengah, with both fast and overnight chargers augmented by renewables and energy storage systems. At Tengah’s neighbourhood centre, drivers will be able to charge their EVs quickly at SP’s innovative Fast-Charging Hubs while attending to their errands. Digital Platform SP Group is rolling out OneTengah, a digital platform which integrates all the capabilities such as centralised cooling, battery energy storage systems, EV-charging stations, as well as data and analytics from other platforms within Tengah. The OneTengah platform will enable town council and facility operators to make use of energy management control and A.I.-enabled insights to monitor the town’s energy resources. They will also have complete visibility of systems in Tengah at an aggregated town or block cluster level. On a single dashboard, they can better monitor system performance and be alerted of anomalies, for quick actions to be taken to enhance the experience of living and working in Tengah. SP has also created a sustainable lifestyle app called myTengah app for an eco-friendly and hasslefree lifestyle. With the app, Tengah residents can access their household utilities consumption, intelligently control their centralised cooling usage, make smart decisions to lower their carbon footprint and integrate sustainability into their everyday lives. To visit the Tengah Experience Centre, simply walk in and register on site or make an appointment3 via the myTengah app, which can be downloaded on both the Apple App and Google Play stores.

An SP Sustainability Ambassador personally and patiently explained to me how it works, with chilled water that is generated from highly energy-efficient modular chiller plants. SP Group then invited me for a sneak preview of the MyTengah Experience Centre. I saw the actual CCS chilled water indoor unit and was able to see how it will look like exactly in my future home, including the actual piping and fittings. I am now convinced and looking forward to saving more money in the long run.” - Mr Steven Ang, 64, future resident who signed up for centralised cooling for his new Tengah home “The MyTengah Experience Centre is such a cool and exciting place. It’s impressive and the fact that we can experience augmented reality elements, it’s the highlight for me as it showcases the intricate details and helps me visualise what has been planned for Tengah.” - Ms Beverly Tan, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah “Sustainability to me is the harmonious co-existence of man and nature.

TNP PHOTO: CHONG JUN LIANG Nearly 1,000 households have signed up for the centralised cooling system (CCS) in the upcoming “forest town” of Tengah, where some 8,000 Build- To-Order (BTO) flats have been launched so far. Home owners who opt for the energy-efficient system will save around 15 per cent to 20 per cent in upfront costs compared with current market rates, and up to 30 per cent in life cycle costs, energy utilities provider SP Group, which runs the system in Tengah, said yesterday. The CCS is one of many smart features that will be implemented in Tengah, which is billed as a “smart energy” town powered by artificial intelligence. Under the CCS, chilled water will be piped to homes from centralised chillers installed on the rooftops of selected Housing Board (HDB) blocks. This is more energy-efficient than conventional air-conditioning systems, said SP Group. The system will be powered by solar energy generated by vertical and horizontal solar panels on the rooftops of HDB blocks. Residents will be able to monitor and control their home energy usage via the MyTengah app, which will be run by SP Group. They will be able to locate electric vehicle charging points via the app, and earn points to be exchanged for rewards by taking part in sustainable activities. A digital dashboard will be installed at the lift lobby of each block, which tracks its utilities consumption and impact on the environment. These eco-boards will also provide residents with tips on how to reduce electrical and water consumption, on top of promoting “sustainable behaviour through utilities-savings competitions between blocks”, said SP Group. Future residents and the public can now visit the new MyTengah Experience Centre at the HDB Hub at Toa Payoh Central. There, they can learn more about the CCS and other ecofriendly solutions that will be implemented in Tengah. Advance booking is recommended, though walk-ins are allowed, subject to capacity. The 97 sq m experience centre can take around 16 visitors at any one time. Mr S. Harsha, managing director of sustainable energy solutions in Singapore for SP Group, said Tengah will be the first town to have a large-scale centralised cooling system, in line with national sustainability efforts. There are plans to provide predictive air-conditioning maintenance services for home owners using the data collected, he said. “This is part of the end-toend service SP Group hopes to provide, on top of the regular maintenance of the centralised chillers,” said Mr Harsha. 98 PER CENT OPT IN Around 98 per cent of the households introduced to the CCS by SP Group staff opted in, although Mr Harsha noted that they were not able to contact all 8,000 households because of the Covid-19 restrictions. Payment will be made only on the day owners collect the keys to their new homes, with airconditioning units by Daikin pre-installed, said SP Group. The group declined to reveal the exact cost of the CCS. ngmich@sph.com.sg Searchhttps://www.spgroup.com.sg/search?tag=centralised-cooling-system Search SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centrehttps://www.spgroup.com.sg/about-us/media-resources/news-and-media-releases/SP-Group-Opens-Singapore-s-First-Smart-Energy-Town-Showcase-at-MyTengah-Experience-Centre News Release SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centre Singapore, 19 October 2020 – SP Group’s (SP) MyTengah Experience Centre, an interactive showcase of SP’s smart energy solutions that will be deployed in Singapore’s first smart energy town at Tengah, will be open to the public from 20 October 2020.

These include digital sustainability displays called Eco Boards at the housing blocks’ lift lobbies to drive community awareness and help residents be more mindful of their block’s utilities’ consumption and impact on the environment. These boards will also provide residents with green tips to lower their electricity and water consumption and promote sustainable behaviour through utilities-savings competitions between blocks. SP will also be implementing EV charging solutions in Tengah, with both fast and overnight chargers augmented by renewables and energy storage systems. At Tengah’s neighbourhood centre, drivers will be able to charge their EVs quickly at SP’s innovative Fast-Charging Hubs while attending to their errands. Digital Platform SP Group is rolling out OneTengah, a digital platform which integrates all the capabilities such as centralised cooling, battery energy storage systems, EV-charging stations, as well as data and analytics from other platforms within Tengah. The OneTengah platform will enable town council and facility operators to make use of energy management control and A.I.-enabled insights to monitor the town’s energy resources. They will also have complete visibility of systems in Tengah at an aggregated town or block cluster level. On a single dashboard, they can better monitor system performance and be alerted of anomalies, for quick actions to be taken to enhance the experience of living and working in Tengah. SP has also created a sustainable lifestyle app called myTengah app for an eco-friendly and hasslefree lifestyle. With the app, Tengah residents can access their household utilities consumption, intelligently control their centralised cooling usage, make smart decisions to lower their carbon footprint and integrate sustainability into their everyday lives. To visit the Tengah Experience Centre, simply walk in and register on site or make an appointment3 via the myTengah app, which can be downloaded on both the Apple App and Google Play stores. For more information on Tengah, please visit mytengah.sg. -Ends- Annex Testimonials from Future Tengah Residents “Initially, I was uncertain about centralised cooling because it is a new concept and I did not fully understand how it works. An SP Sustainability Ambassador personally and patiently explained to me how it works, with chilled water that is generated from highly energy-efficient modular chiller plants. SP Group then invited me for a sneak preview of the MyTengah Experience Centre. I saw the actual CCS chilled water indoor unit and was able to see how it will look like exactly in my future home, including the actual piping and fittings. I am now convinced and looking forward to saving more money in the long run.” - Mr Steven Ang, 64, future resident who signed up for centralised cooling for his new Tengah home “The MyTengah Experience Centre is such a cool and exciting place. It’s impressive and the fact that we can experience augmented reality elements, it’s the highlight for me as it showcases the intricate details and helps me visualise what has been planned for Tengah.” - Ms Beverly Tan, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah “Sustainability to me is the harmonious co-existence of man and nature. It is about achieving an equilibrium and balance. The MyTengah Experience Centre showcases the solution that can make this happen. To me, it’s also about savings and with CCS, we can save up to 30 per cent in our energy consumption. It is so economical.” - Mr Shaun Wong, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah About SP Group SP Group is a leading utilities group in the Asia Pacific, driving a low-carbon, smart energy future for its customers.

The 38-year-old Principal Engineer is part of the team designing and building the first centralised cooling system (CCS) for a residential estate in Singapore – in the Tengah eco-town. Instead of individual compressor units mounted on aircon ledges, Mr Liu is tasked to build a centralised system which circulates chilled water to and from each flat to cool air within the flat, thus delivering air-conditioning service to 19,000 households in the estate. The first homes will be ready in 2023. “It is definitely a challenge because we have to work with many other parties to overcome the space constraints,” says Mr Liu. In his previous posting in SP Group, Mr Liu worked at an underground district cooling system that serves the Marina Bay central business district. But this time, Mr Liu has to deal with space constraints of a different kind. “In HDB flats, it’s not cost-efficient to have large underground spaces, so we have to think out of the box and find space for our cooling equipment,” Mr Liu shares. Eventually, the project team decided to place the CCS equipment on the HDB block roof, which would allow precious ground space to be used by the community. HDB flat rooftops would host the CCS equipment which service a cluster of HDB blocks. This arrangement would optimise the cooling output of the CCS equipment, achieving both energy efficiency and supply reliability. Mr Liu is proud that he plays a part in transforming the energy sector to meet climate goals.

We are helping to improve lives by the meaningful transformation of the power industry. This brings me a lot of satisfaction as an engineer,” he says. Reaping benefits from economies of scale In a CCS, a few interconnected centralised plants produce chilled water which is piped to individual households. “Colder” chilled water produced at the centralised plants is circulated to the indoor air-conditioner (known as chilled water fan coil unit or FCU) in each flat. The FCU recirculates the air within the flat and cools the air. In the process, the chilled water is “warmed” up. The warmer water is then returned to the centralised plants to be chilled again and repeat the process. Because the centralised chilled water plants are 30 per cent more energy efficient by design than individual split units found typically in households, CCS is more economical for air-conditioning of flats. Mr Liu Yue is the deputy lead for the construction of the centralised cooling system that will deliver air-conditioning service to 19,000 households in Tengah eco-town. PHOTO: SP GROUP Air-conditioned comfort with lower emissions Air-conditioning is ubiquitous in tropical Singapore. According to the Department of Statistics, about 80 per cent of Singapore households own air-conditioners, and from NEA household electricity consumption profile, air-conditioning contributes about 24 per cent of the average household electricity consumption. With rising incomes and warming temperatures, air-conditioning ownership and the use of air conditioners are set to rise. Worldwide, the use of air-conditioners results in the emission of nearly two million tonnes of carbon dioxide every year, or about 4 per cent of the global share. There is therefore an increasing need to reduce carbon footprint from more energy efficient air-conditioning systems. The reduction in electricity consumption from CCS will contribute towards Singapore’s ambitious carbon footprint reduction commitments. Singapore aims to accelerate its timeline to reduce greenhouse gas emissions, peaking emissions in 2030 and achieving net-zero emissions by 2050. While Singapore’s carbon emissions represent a small percentage of the global share (0.13 per cent in 2020), Singapore’s per capita emissions are very high, about twice the global average at 12 tonnes annually. If Singaporeans can reduce their carbon emissions significantly, it would demonstrate how people can meaningfully counteract climate change without severely lowering their standard of living. Mr Liu is energised by his contribution to help Singapore meet its climate goals. “The CCS we are building will enable Tengah residents to lower their carbon footprint through an energy-efficient cooling system. Just by living in the estate, each resident has already started the sustainability journey. This is a huge motivating factor to every engineer working on the Tengah project. “We started from ground zero and had our fair share of roadblocks in the journey. With all the hard work we put in, it is very rewarding to see everything come to fruition. I am glad to be able to play a part in pioneering the most futuristic town in Singapore towards smart and sustainable living. I guess it's my way of leaving my mark – a green one,” adds Mr Liu. Energy-efficient cooling for a warming world Leading the effort for more efficient cooling systems, SP Group will be implementing various types of cooling systems in different capacities, both in commercial and residential buildings. Its flagship district cooling system in the Marina Bay CBD network will be expanding to cool 28 commercial buildings by 2026. The savings in electricity consumption is estimated to reduce about 20,000 tonnes of carbon emissions annually, equivalent to removing 17,672 cars off the road. SP Group is establishing Singapore’s largest industrial district cooling system for STMicroelectronics at the Ang Mo Kio Technopark. By the time it is operational in 2025, it will reduce carbon emissions by up to 120,000 tonnes annually. SP Group is also constructing a distributed district cooling network in Tampines, where seven existing buildings will be retrofitted by 2025. Transitioning the world into a decarbonised future Beyond its role as the national grid operator, SP Group actively pursues sustainability initiatives as a key part of Singapore’s climate strategy. Its climate initiatives include a nationwide electric vehicle (EV) charging network, deploying rooftop solar energy generation, and smart electricity metering to monitor and reduce usage. SP Group has also exported these technologies to overseas markets where there is demand for sustainable energy solutions. SP Group has provided expertise to build district cooling and heating systems, smart metering and solar power generation in cities in China, Thailand and Vietnam.

Home owners who opt for the energy-efficient system will save around 15 per cent to 20 per cent in upfront costs compared with current market rates, and up to 30 per cent in life cycle costs, energy utilities provider SP Group, which runs the system in Tengah, said yesterday. The CCS is one of many smart features that will be implemented in Tengah, which is billed as a “smart energy” town powered by artificial intelligence. Under the CCS, chilled water will be piped to homes from centralised chillers installed on the rooftops of selected Housing Board blocks. This is more energy-efficient compared with conventional air-conditioning systems, said SP Group. The system will be powered by solar energy generated by vertical and horizontal solar panels on the rooftops of HDB blocks. Residents can also monitor and control their home energy usage via the MyTengah app, which will be run by SP Group. They will be able to locate electric vehicle charging points via the app as well, and accumulate points by participating in sustainable activities that can be exchanged for rewards. A digital dashboard will be installed at the lift lobby of each housing block, which tracks the block’s utilities consumption and impact on the environment. These eco-boards will also provide residents with tips on how to reduce electrical and water consumption, on top of promoting “sustainable behaviour through utilities-savings competitions between blocks”, said SP Group. From today, future residents and members of the public can visit the new MyTengah Experience Centre at HDB Hub in Toa Payoh Central to learn more about the CCS and other eco-friendly solutions that will be implemented in Tengah. Visitors will be able to see the setup of the air-conditioning system in a home setting and learn how the system operates through various interactive displays. Advance booking is recommended, although walk-ins are allowed, subject to capacity limits. The 97 sq m experience centre can take around 16 visitors at any one time. Mr S Harsha, managing director of sustainable energy solutions in Singapore for SP Group, said that Tengah will be the first town in Singapore to have a large-scale centralised cooling system, in line with national sustainability efforts. There are plans to provide predictive air-conditioning maintenance services for home owners using the data collected, he said. “This is part of the end-to-end service SP Group hopes to provide, on top of the regular maintenance of the centralised chillers,” he added. Around 98 per cent of the households that were introduced to the CCS by staff from SP Group opted in, although Mr S Harsha noted that they were not able to contact Salesman Lim Kwok Mun and his wife Susan Lee checking out the air-conditioning system at the MyTengah Experience Centre at HDB Hub in Toa Payoh yesterday. From today, future residents and members of the public can visit the centre to learn more about Tengah’s eco-friendly solutions.

Payment will be made only on the day home owners collect the keys to their new homes, with air-conditioning units by Daikin pre-installed in their homes, said SP Group. The group declined to reveal the exact cost of the CCS. When completed, Tengah could comprise around 30,000 public housing units and 12,000 private ones. Salesman Lim Kwok Mun, 71, and his wife Susan Lee, 68, a housewife, were drawn to the greenery in Tengah and decided to apply for a three-room BTO flat in Plantation district last year. Said Mr Lim: “The idea of a centralised cooling system is very cool; it’s like a hotel where you go in and everything is managed for you. “We are quite adventurous and want to keep up with technology, so we want to make our retirement home a smart home.” ngmich@sph.com.sg KEEPING UP WITH TECH The idea of a centralised cooling system is very cool; it’s like a hotel where you go in and everything is managed for you.

Energy Town Showcase at MyTengah Experience Centrehttps://www.spgroup.com.sg/about-us/media-resources/news-and-media-releases/SP-Group-Opens-Singapore-s-First-Smart-Energy-Town-Showcase-at-MyTengah-Experience-Centre News Release SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centre Singapore, 19 October 2020 – SP Group’s (SP) MyTengah Experience Centre, an interactive showcase of SP’s smart energy solutions that will be deployed in Singapore’s first smart energy town at Tengah, will be open to the public from 20 October 2020. SP will bring Singapore’s first large-scale residential centralised cooling system to Tengah. Located at the HDB Hub in Toa Payoh, the MyTengah Experience Centre will give future Tengah residents and visitors a first-hand look and feel of living in the A.I.-enabled, eco-friendly, smart energy town. It provides visitors with an immersive experience of the benefits of the smart energy innovations that will be installed and integrated across more than 20,000 residential, commercial and community facilities. These innovations include the centralised cooling system, digital display boards of energy consumption at residents’ blocks, charging stations for electric vehicles, and a digital platform that enables a near real-time monitoring of these solutions. Mr Stanley Huang, Group Chief Executive Officer of SP Group said, “SP wants to create a lowcarbon, smart energy Singapore. Tengah will be the model for low-carbon smart energy towns in Singapore. The MyTengah Experience Centre brings to life the benefits that residents will enjoy with our smart energy solutions, which will enable residents to integrate sustainability into their everyday lives.” Residential Centralised Cooling In collaboration with the Housing & Development Board (HDB), SP will bring Singapore’s first largescale residential centralised cooling system1 to Tengah. Air-conditioning accounts for a quarter of an average Singaporean household’s electricity consumption2 . With SP’s centralised cooling system, Tengah residents can enjoy as much as 30 per cent energy savings. Chilled water will be centrally produced from interconnected modular chiller plants built on the HDB roof tops before it is distributed to residential and commercial units for air-conditioning. To maximise the limited space available in Tengah, SP is also testing both conventional and vertical solar panels, known as Building Integrated Photovoltaics (BIPV). The solar energy generated from these sources will then be used to power the centralised cooling system to meet the township’s cooling needs. The centralised cooling system will also be serviced by SP, bringing greater convenience to the Tengah residents. Smart Energy Solutions In addition to centralised cooling system, SP will be installing other smart energy solutions across Tengah. These include digital sustainability displays called Eco Boards at the housing blocks’ lift lobbies to drive community awareness and help residents be more mindful of their block’s utilities’ consumption and impact on the environment. These boards will also provide residents with green tips to lower their electricity and water consumption and promote sustainable behaviour through utilities-savings competitions between blocks. SP will also be implementing EV charging solutions in Tengah, with both fast and overnight chargers augmented by renewables and energy storage systems. At Tengah’s neighbourhood centre, drivers will be able to charge their EVs quickly at SP’s innovative Fast-Charging Hubs while attending to their errands. Digital Platform SP Group is rolling out OneTengah, a digital platform which integrates all the capabilities such as centralised cooling, battery energy storage systems, EV-charging stations, as well as data and analytics from other platforms within Tengah. The OneTengah platform will enable town council and facility operators to make use of energy management control and A.I.-enabled insights to monitor the town’s energy resources. They will also have complete visibility of systems in Tengah at an aggregated town or block cluster level. On a single dashboard, they can better monitor system performance and be alerted of anomalies, for quick actions to be taken to enhance the experience of living and working in Tengah. SP has also created a sustainable lifestyle app called myTengah app for an eco-friendly and hasslefree lifestyle. With the app, Tengah residents can access their household utilities consumption, intelligently control their centralised cooling usage, make smart decisions to lower their carbon footprint and integrate sustainability into their everyday lives. To visit the Tengah Experience Centre, simply walk in and register on site or make an appointment3 via the myTengah app, which can be downloaded on both the Apple App and Google Play stores. For more information on Tengah, please visit mytengah.sg. -Ends- Annex Testimonials from Future Tengah Residents “Initially, I was uncertain about centralised cooling because it is a new concept and I did not fully understand how it works. An SP Sustainability Ambassador personally and patiently explained to me how it works, with chilled water that is generated from highly energy-efficient modular chiller plants. SP Group then invited me for a sneak preview of the MyTengah Experience Centre. I saw the actual CCS chilled water indoor unit and was able to see how it will look like exactly in my future home, including the actual piping and fittings. I am now convinced and looking forward to saving more money in the long run.” - Mr Steven Ang, 64, future resident who signed up for centralised cooling for his new Tengah home “The MyTengah Experience Centre is such a cool and exciting place. It’s impressive and the fact that we can experience augmented reality elements, it’s the highlight for me as it showcases the intricate details and helps me visualise what has been planned for Tengah.” - Ms Beverly Tan, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah “Sustainability to me is the harmonious co-existence of man and nature. It is about achieving an equilibrium and balance. The MyTengah Experience Centre showcases the solution that can make this happen. To me, it’s also about savings and with CCS, we can save up to 30 per cent in our energy consumption. It is so economical.” - Mr Shaun Wong, 23, visitor invited for a preview of the MyTengah Experience Centre, applying for a new home in Tengah About SP Group SP Group is a leading utilities group in the Asia Pacific, driving a low-carbon, smart energy future for its customers.

SP will bring Singapore’s first large-scale residential centralised cooling system to Tengah. Located at the HDB Hub in Toa Payoh, the MyTengah Experience Centre will give future Tengah residents and visitors a first-hand look and feel of living in the A.I.-enabled, eco-friendly, smart energy town. It provides visitors with an immersive experience of the benefits of the smart energy innovations that will be installed and integrated across more than 20,000 residential, commercial and community facilities. These innovations include the centralised cooling system, digital display boards of energy consumption at residents’ blocks, charging stations for electric vehicles, and a digital platform that enables a near real-time monitoring of these solutions. Mr Stanley Huang, Group Chief Executive Officer of SP Group said, “SP wants to create a lowcarbon, smart energy Singapore. Tengah will be the model for low-carbon smart energy towns in Singapore. The MyTengah Experience Centre brings to life the benefits that residents will enjoy with our smart energy solutions, which will enable residents to integrate sustainability into their everyday lives.” Residential Centralised Cooling In collaboration with the Housing & Development Board (HDB), SP will bring Singapore’s first largescale residential centralised cooling system1 to Tengah. Air-conditioning accounts for a quarter of an average Singaporean household’s electricity consumption2 . With SP’s centralised cooling system, Tengah residents can enjoy as much as 30 per cent energy savings. Chilled water will be centrally produced from interconnected modular chiller plants built on the HDB roof tops before it is distributed to residential and commercial units for air-conditioning. To maximise the limited space available in Tengah, SP is also testing both conventional and vertical solar panels, known as Building Integrated Photovoltaics (BIPV). The solar energy generated from these sources will then be used to power the centralised cooling system to meet the township’s cooling needs. The centralised cooling system will also be serviced by SP, bringing greater convenience to the Tengah residents. Smart Energy Solutions In addition to centralised cooling system, SP will be installing other smart energy solutions across Tengah. These include digital sustainability displays called Eco Boards at the housing blocks’ lift lobbies to drive community awareness and help residents be more mindful of their block’s utilities’ consumption and impact on the environment. These boards will also provide residents with green tips to lower their electricity and water consumption and promote sustainable behaviour through utilities-savings competitions between blocks. SP will also be implementing EV charging solutions in Tengah, with both fast and overnight chargers augmented by renewables and energy storage systems. At Tengah’s neighbourhood centre, drivers will be able to charge their EVs quickly at SP’s innovative Fast-Charging Hubs while attending to their errands. Digital Platform SP Group is rolling out OneTengah, a digital platform which integrates all the capabilities such as centralised cooling, battery energy storage systems, EV-charging stations, as well as data and analytics from other platforms within Tengah. The OneTengah platform will enable town council and facility operators to make use of energy management control and A.I.-enabled insights to monitor the town’s energy resources. They will also have complete visibility of systems in Tengah at an aggregated town or block cluster level. On a single dashboard, they can better monitor system performance and be alerted of anomalies, for quick actions to be taken to enhance the experience of living and working in Tengah. SP has also created a sustainable lifestyle app called myTengah app for an eco-friendly and hasslefree lifestyle. With the app, Tengah residents can access their household utilities consumption, intelligently control their centralised cooling usage, make smart decisions to lower their carbon footprint and integrate sustainability into their everyday lives. To visit the Tengah Experience Centre, simply walk in and register on site or make an appointment3 via the myTengah app, which can be downloaded on both the Apple App and Google Play stores.

TNP PHOTO: CHONG JUN LIANG Nearly 1,000 households have signed up for the centralised cooling system (CCS) in the upcoming “forest town” of Tengah, where some 8,000 Build- To-Order (BTO) flats have been launched so far. Home owners who opt for the energy-efficient system will save around 15 per cent to 20 per cent in upfront costs compared with current market rates, and up to 30 per cent in life cycle costs, energy utilities provider SP Group, which runs the system in Tengah, said yesterday. The CCS is one of many smart features that will be implemented in Tengah, which is billed as a “smart energy” town powered by artificial intelligence. Under the CCS, chilled water will be piped to homes from centralised chillers installed on the rooftops of selected Housing Board (HDB) blocks. This is more energy-efficient than conventional air-conditioning systems, said SP Group. The system will be powered by solar energy generated by vertical and horizontal solar panels on the rooftops of HDB blocks. Residents will be able to monitor and control their home energy usage via the MyTengah app, which will be run by SP Group. They will be able to locate electric vehicle charging points via the app, and earn points to be exchanged for rewards by taking part in sustainable activities. A digital dashboard will be installed at the lift lobby of each block, which tracks its utilities consumption and impact on the environment. These eco-boards will also provide residents with tips on how to reduce electrical and water consumption, on top of promoting “sustainable behaviour through utilities-savings competitions between blocks”, said SP Group. Future residents and the public can now visit the new MyTengah Experience Centre at the HDB Hub at Toa Payoh Central. There, they can learn more about the CCS and other ecofriendly solutions that will be implemented in Tengah. Advance booking is recommended, though walk-ins are allowed, subject to capacity. The 97 sq m experience centre can take around 16 visitors at any one time. Mr S. Harsha, managing director of sustainable energy solutions in Singapore for SP Group, said Tengah will be the first town to have a large-scale centralised cooling system, in line with national sustainability efforts. There are plans to provide predictive air-conditioning maintenance services for home owners using the data collected, he said. “This is part of the end-toend service SP Group hopes to provide, on top of the regular maintenance of the centralised chillers,” said Mr Harsha. 98 PER CENT OPT IN Around 98 per cent of the households introduced to the CCS by SP Group staff opted in, although Mr Harsha noted that they were not able to contact all 8,000 households because of the Covid-19 restrictions. Payment will be made only on the day owners collect the keys to their new homes, with airconditioning units by Daikin pre-installed, said SP Group. The group declined to reveal the exact cost of the CCS. ngmich@sph.com.sg Searchhttps://www.spgroup.com.sg/search?tag=centralised-cooling-system Search SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centrehttps://www.spgroup.com.sg/about-us/media-resources/news-and-media-releases/SP-Group-Opens-Singapore-s-First-Smart-Energy-Town-Showcase-at-MyTengah-Experience-Centre News Release SP Group Opens Singapore’s First Smart Energy Town Showcase at MyTengah Experience Centre Singapore, 19 October 2020 – SP Group’s (SP) MyTengah Experience Centre, an interactive showcase of SP’s smart energy solutions that will be deployed in Singapore’s first smart energy town at Tengah, will be open to the public from 20 October 2020.

The 38-year-old Principal Engineer is part of the team designing and building the first centralised cooling system (CCS) for a residential estate in Singapore – in the Tengah eco-town. Instead of individual compressor units mounted on aircon ledges, Mr Liu is tasked to build a centralised system which circulates chilled water to and from each flat to cool air within the flat, thus delivering air-conditioning service to 19,000 households in the estate. The first homes will be ready in 2023. “It is definitely a challenge because we have to work with many other parties to overcome the space constraints,” says Mr Liu. In his previous posting in SP Group, Mr Liu worked at an underground district cooling system that serves the Marina Bay central business district. But this time, Mr Liu has to deal with space constraints of a different kind. “In HDB flats, it’s not cost-efficient to have large underground spaces, so we have to think out of the box and find space for our cooling equipment,” Mr Liu shares. Eventually, the project team decided to place the CCS equipment on the HDB block roof, which would allow precious ground space to be used by the community. HDB flat rooftops would host the CCS equipment which service a cluster of HDB blocks. This arrangement would optimise the cooling output of the CCS equipment, achieving both energy efficiency and supply reliability.

We are helping to improve lives by the meaningful transformation of the power industry. This brings me a lot of satisfaction as an engineer,” he says. Reaping benefits from economies of scale In a CCS, a few interconnected centralised plants produce chilled water which is piped to individual households. “Colder” chilled water produced at the centralised plants is circulated to the indoor air-conditioner (known as chilled water fan coil unit or FCU) in each flat. The FCU recirculates the air within the flat and cools the air. In the process, the chilled water is “warmed” up. The warmer water is then returned to the centralised plants to be chilled again and repeat the process. Because the centralised chilled water plants are 30 per cent more energy efficient by design than individual split units found typically in households, CCS is more economical for air-conditioning of flats. Mr Liu Yue is the deputy lead for the construction of the centralised cooling system that will deliver air-conditioning service to 19,000 households in Tengah eco-town. PHOTO: SP GROUP Air-conditioned comfort with lower emissions Air-conditioning is ubiquitous in tropical Singapore. According to the Department of Statistics, about 80 per cent of Singapore households own air-conditioners, and from NEA household electricity consumption profile, air-conditioning contributes about 24 per cent of the average household electricity consumption. With rising incomes and warming temperatures, air-conditioning ownership and the use of air conditioners are set to rise. Worldwide, the use of air-conditioners results in the emission of nearly two million tonnes of carbon dioxide every year, or about 4 per cent of the global share. There is therefore an increasing need to reduce carbon footprint from more energy efficient air-conditioning systems. The reduction in electricity consumption from CCS will contribute towards Singapore’s ambitious carbon footprint reduction commitments. Singapore aims to accelerate its timeline to reduce greenhouse gas emissions, peaking emissions in 2030 and achieving net-zero emissions by 2050. While Singapore’s carbon emissions represent a small percentage of the global share (0.13 per cent in 2020), Singapore’s per capita emissions are very high, about twice the global average at 12 tonnes annually. If Singaporeans can reduce their carbon emissions significantly, it would demonstrate how people can meaningfully counteract climate change without severely lowering their standard of living. Mr Liu is energised by his contribution to help Singapore meet its climate goals. “The CCS we are building will enable Tengah residents to lower their carbon footprint through an energy-efficient cooling system. Just by living in the estate, each resident has already started the sustainability journey. This is a huge motivating factor to every engineer working on the Tengah project. “We started from ground zero and had our fair share of roadblocks in the journey. With all the hard work we put in, it is very rewarding to see everything come to fruition. I am glad to be able to play a part in pioneering the most futuristic town in Singapore towards smart and sustainable living. I guess it's my way of leaving my mark – a green one,” adds Mr Liu. Energy-efficient cooling for a warming world Leading the effort for more efficient cooling systems, SP Group will be implementing various types of cooling systems in different capacities, both in commercial and residential buildings. Its flagship district cooling system in the Marina Bay CBD network will be expanding to cool 28 commercial buildings by 2026. The savings in electricity consumption is estimated to reduce about 20,000 tonnes of carbon emissions annually, equivalent to removing 17,672 cars off the road. SP Group is establishing Singapore’s largest industrial district cooling system for STMicroelectronics at the Ang Mo Kio Technopark. By the time it is operational in 2025, it will reduce carbon emissions by up to 120,000 tonnes annually. SP Group is also constructing a distributed district cooling network in Tampines, where seven existing buildings will be retrofitted by 2025. Transitioning the world into a decarbonised future Beyond its role as the national grid operator, SP Group actively pursues sustainability initiatives as a key part of Singapore’s climate strategy. Its climate initiatives include a nationwide electric vehicle (EV) charging network, deploying rooftop solar energy generation, and smart electricity metering to monitor and reduce usage. SP Group has also exported these technologies to overseas markets where there is demand for sustainable energy solutions. SP Group has provided expertise to build district cooling and heating systems, smart metering and solar power generation in cities in China, Thailand and Vietnam.

The 38-year-old Principal Engineer is part of the team designing and building the first centralised cooling system (CCS) for a residential estate in Singapore – in the Tengah eco-town. Instead of individual compressor units mounted on aircon ledges, Mr Liu is tasked to build a centralised system which circulates chilled water to and from each flat to cool air within the flat, thus delivering air-conditioning service to 19,000 households in the estate. The first homes will be ready in 2023. “It is definitely a challenge because we have to work with many other parties to overcome the space constraints,” says Mr Liu. In his previous posting in SP Group, Mr Liu worked at an underground district cooling system that serves the Marina Bay central business district. But this time, Mr Liu has to deal with space constraints of a different kind. “In HDB flats, it’s not cost-efficient to have large underground spaces, so we have to think out of the box and find space for our cooling equipment,” Mr Liu shares. Eventually, the project team decided to place the CCS equipment on the HDB block roof, which would allow precious ground space to be used by the community. HDB flat rooftops would host the CCS equipment which service a cluster of HDB blocks. This arrangement would optimise the cooling output of the CCS equipment, achieving both energy efficiency and supply reliability.

Home owners who opt for the energy-efficient system will save around 15 per cent to 20 per cent in upfront costs compared with current market rates, and up to 30 per cent in life cycle costs, energy utilities provider SP Group, which runs the system in Tengah, said yesterday. The CCS is one of many smart features that will be implemented in Tengah, which is billed as a “smart energy” town powered by artificial intelligence. Under the CCS, chilled water will be piped to homes from centralised chillers installed on the rooftops of selected Housing Board blocks. This is more energy-efficient compared with conventional air-conditioning systems, said SP Group. The system will be powered by solar energy generated by vertical and horizontal solar panels on the rooftops of HDB blocks. Residents can also monitor and control their home energy usage via the MyTengah app, which will be run by SP Group. They will be able to locate electric vehicle charging points via the app as well, and accumulate points by participating in sustainable activities that can be exchanged for rewards. A digital dashboard will be installed at the lift lobby of each housing block, which tracks the block’s utilities consumption and impact on the environment. These eco-boards will also provide residents with tips on how to reduce electrical and water consumption, on top of promoting “sustainable behaviour through utilities-savings competitions between blocks”, said SP Group. From today, future residents and members of the public can visit the new MyTengah Experience Centre at HDB Hub in Toa Payoh Central to learn more about the CCS and other eco-friendly solutions that will be implemented in Tengah. Visitors will be able to see the setup of the air-conditioning system in a home setting and learn how the system operates through various interactive displays. Advance booking is recommended, although walk-ins are allowed, subject to capacity limits. The 97 sq m experience centre can take around 16 visitors at any one time. Mr S Harsha, managing director of sustainable energy solutions in Singapore for SP Group, said that Tengah will be the first town in Singapore to have a large-scale centralised cooling system, in line with national sustainability efforts. There are plans to provide predictive air-conditioning maintenance services for home owners using the data collected, he said. “This is part of the end-to-end service SP Group hopes to provide, on top of the regular maintenance of the centralised chillers,” he added. Around 98 per cent of the households that were introduced to the CCS by staff from SP Group opted in, although Mr S Harsha noted that they were not able to contact Salesman Lim Kwok Mun and his wife Susan Lee checking out the air-conditioning system at the MyTengah Experience Centre at HDB Hub in Toa Payoh yesterday. From today, future residents and members of the public can visit the centre to learn more about Tengah’s eco-friendly solutions.

Registration Number: 199406577N | SP Power Limited and its subsidiaries CHAIRMAN'S MESSAGE 2022 “I believe that with the strong partnership forged with our stakeholders, we will remain committed to creating greater value for our customers and empowering the future of energy together.” The past year has been a test of resilience, agility and unity. Reflecting on SP Group’s performance, it has been a remarkable year on several counts. Despite unprecedented challenges and constraints posed by the pandemic, supply chain disruptions and a labour crunch, we concluded the year with a record electricity supply interruption performance, exceeded targets for gas operations and workplace safety, and attained an all-time high employee engagement. As a provider of essential energy services, SP Group has been steadfast in ensuring reliable and secure supply of electricity and gas for our customers, amidst change and transformation around us. With the gradual easing of safe management measures, we have doubled our efforts in asset maintenance and renewal works to ensure long-term network reliability. Recognising climate change imperatives, we have stepped up efforts in developing sustainable energy solutions. We have expanded our low-carbon footprint in Singapore and overseas, providing energy solutions through district cooling, electromobility and renewable energy investments. The difficult operating environment has not deterred us from continued investment in building capabilities as we pursue technology, people development and process innovation, and maintain a strong financial position to meet future needs. MANAGING RELIABLE NETWORKS Our teams work round the clock to run robust operations of the grid, delivering reliable power and gas supply to more than 1.6 million commercial, industrial and residential customers in Singapore. - 2 - SP GROUP ANNUAL REPORT 2022 CHAIRMAN'S MESSAGE 2022 Efforts spanning asset planning, renewal and maintenance have contributed to a record network reliability performance. On average last year, a customer experienced a record low 6.6 seconds of electricity interruption and 11.9 seconds of gas interruption. In the past year, we completed 18 renewal projects, and replaced 140km of cables, 263 transformers and 1,044 switchgear panels in our electricity distribution infrastructure. We invest in infrastructure and technology such as artificial intelligence and machine learning. This enables us to conduct comprehensive real-time monitoring, trend analysis and diagnostics so as to predict and manage future network problems before they occur. Forty critical distribution substations have been installed with online condition monitoring equipment, with another 99 more in the pipeline. In anticipation of growth in electricity demand, electrification and renewable and distributed energy deployment, there is a need for a - 3 - SP GROUP ANNUAL REPORT 2022 CHAIRMAN'S MESSAGE 2022 high-fidelity digital replica of Singapore’s future electricity grid. SP is developing a Grid Digital Twin, an innovative in-house creation to better plan, operate and maintain the national power grid through modelling, simulations, condition monitoring and asset health analysis. We draw on up-to-date information from over 12,000 substations across our entire electricity network. As part of our gas asset renewal and maintenance programme, we concluded an open tank inspection for a gas holder and successfully completed the renewal of two town gas offtake stations. Another seven stations are scheduled for completion in the next three years. Our Technical Officer performing condition monitoring of our electricity asset We carried out projects to lay more than 70km of durable polyethylene pipes to replace ageing ductile iron pipelines, thereby reducing the risk of gas leakage. Another key milestone was the completion of the in-line inspection operations for a subsea gas pipeline connecting Indonesia to Singapore to ensure integrity of the pipeline. We have adopted new technologies such as the implementation of a new gas enterprise asset management system. These initiatives will optimise operational effectiveness and enable us to better assess the condition of our assets in order to facilitate timely replacement and minimise unplanned interruption. SP is driving the national rollout of smart meters to help customers optimise their energy efficiency. We have installed 648,000 advanced electricity meters for businesses and households. Under the project awarded by PUB in 2021 to supply, install and manage smart water meters, we are making steady progress in rolling out 309,100 smart water meters under the first phase of PUB’s Smart Water Meter Programme. With these meters, commercial and residential customers can track their electricity and water consumption, better understand their usage patterns and achieve better efficiency. - 4 - SP GROUP ANNUAL REPORT 2022 CHAIRMAN'S MESSAGE 2022 UPHOLDING SAFETY STANDARDS We carried out projects to lay more than 70km of durable polyethylene pipes to replace ageing ductile iron pipelines, thereby reducing the risk of gas leakage.

The digital twin of Singapore’s power grid will comprise two key models: Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory3   Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)4, the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).   Key benefits of the Grid Digital Twin are: Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.   Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads.   Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.   Grid Digital Twin comprising the Asset Twin and Network Twin (Image Credit: Energy Market Authority) KEY VISUAL FOR ASSET TWIN Overview of Asset Health and Criticality Index for the Distribution Network (Image Credit: SP Group-NTU Joint Laboratory) KEY VISUAL FOR NETWORK TWIN Dashboard for analysing electric vehicle charging impact on the distribution grid using the Network Twin (Image Credit: Institute of High Performance Computing and TUMCREATE) 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources.   The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: Asset Twin1 for the health management of grid assets (such as substations, transformers, cables); and Network Twin2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for different needs (such as installation of electric vehicle chargers, and connection of solar photovoltaic systems and energy storage systems). Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network.   In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

The digital twin of Singapore’s power grid will comprise two key models: Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory3   Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)4, the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).   Key benefits of the Grid Digital Twin are: Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.   Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads.   Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.   Grid Digital Twin comprising the Asset Twin and Network Twin (Image Credit: Energy Market Authority) KEY VISUAL FOR ASSET TWIN Overview of Asset Health and Criticality Index for the Distribution Network (Image Credit: SP Group-NTU Joint Laboratory) KEY VISUAL FOR NETWORK TWIN Dashboard for analysing electric vehicle charging impact on the distribution grid using the Network Twin (Image Credit: Institute of High Performance Computing and TUMCREATE) 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources.   The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: Asset Twin1 for the health management of grid assets (such as substations, transformers, cables); and Network Twin2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for different needs (such as installation of electric vehicle chargers, and connection of solar photovoltaic systems and energy storage systems). Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network.   In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

The digital twin of Singapore’s power grid will comprise two key models: Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory3   Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)4, the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).   Key benefits of the Grid Digital Twin are: Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.   Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads.   Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.   Grid Digital Twin comprising the Asset Twin and Network Twin (Image Credit: Energy Market Authority) KEY VISUAL FOR ASSET TWIN Overview of Asset Health and Criticality Index for the Distribution Network (Image Credit: SP Group-NTU Joint Laboratory) KEY VISUAL FOR NETWORK TWIN Dashboard for analysing electric vehicle charging impact on the distribution grid using the Network Twin (Image Credit: Institute of High Performance Computing and TUMCREATE) 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources.   The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: Asset Twin1 for the health management of grid assets (such as substations, transformers, cables); and Network Twin2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for different needs (such as installation of electric vehicle chargers, and connection of solar photovoltaic systems and energy storage systems). Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network.   In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources. 2 The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: • Asset Twin 1 for the health management of grid assets (such as substations, transformers, cables); and • Network Twin 2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) 3 Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network. 4 In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations. 5 Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.” 6 Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.” 7 When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.

ANNEX FACTSHEET ON THE SINGAPORE POWER GRID DIGITAL TWIN A digital twin is a virtual model of physical infrastructure, processes and systems that can carry out various functions such as intelligent data analysis, computer modelling and simulation and machine learning to support users in improving planning and decision-making processes. 2 The digital twin of Singapore’s power grid will comprise two key models: a. Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory 3 . b. Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO) 4 , the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO). 3 The SP Group - NTU Joint Lab was established between SP Group and NTU in 2020, to explore energy-related projects in the areas of asset management and network operations. 4 MESMO is one of two primary simulation technologies that is used in the Singapore Integrated Transport Energy Model (SITEM) project.

SATURDAY, NOVEMBER 23, 2013 Careers in Engineering Packing a lot of power Principal engineer Chan Hong Jiang relishes the unpredictable challenges that he faces in his job at Singapore Power by suresh nair PRINCIPAL engineer Chan Hong Jiang enjoys challenges and switches on when there is a major blackout. Thankfully, it is not often that power outages occur here and Singapore has one of the fewest and shortest power outages of cities worldwide, as rated by international industry indices, thanks to Singapore Power’s world-class electricity and gas transmission, distribution and market support services. “When a power outage occurs, the immediate concern is to restore the supply to affected customers safely and quickly,” says Mr Chan, 32, who has worked for seven years with Singapore Power, which covers over a million Singapore industrial and domestic customers. His team looks after the operations and maintenance of electricity distribution networks in the southern region of Singapore, which covers the Orchard Road shopping belt, Sentosa and the Central Business District area. The daily work, which he calls an unpredictable challenge, includes maintenance, repair and renewal of power equipment such as switchgear, transformers and power cables of various voltages from 400V up to 66kV deployed in the various electrical substations. “We also have to respond expeditiously to any power outages or incidents that occur at any time and restore electrical supply to affected customers,” he adds. “I have been here seven years, there is never a typical day at work. I’m always learning and growing in my job.” He relishes “bigger challenges” in national and regional projects, citing the National Day Parade (NDP) 2010 and Guangzhou 2010 Asian Games which “gave me the chance to hone my technical skills”. His role in the technical support committee for NDP 2010 was to ensure there were no power outages in the vicinity of the surrounding parade area and to have quick restoration of power supply in the event of any supply failure. Going to Guangzhou for a week for the Asian Games was “another breathtaking challenge” after China Southern Power Grid wanted condition monitoring work on the power supply infrastructure for the Guangzhou Asian Games. “I was part of the team carrying out cable diagnostic tests on the Guangzhou power network. During the trip, we shared our experience in condition monitoring with our counterparts and I also learnt about their work processes and network equipment. This was indeed an eyeopening experience.” Mr Chan studied at Raffles Institution and Victoria Junior College, after which he earned a degree in electrical engineering at the National University of Singapore. He joined SP Power- Grid soon after graduation and was posted to the Regional Network South as an executive engineer. His work philosophy is delivering quality work without looking at the clock. He says: “I think one key quality is the willingness to go the extra mile to ensure that the work carried out is up to mark. Any slip-up will not only affect the company’s performance, but could also potentially affect a very large customer base or in the worst case, cause a safety hazard to the public.” We also have to respond expeditiously to any power outages or incidents that occur at any time and restore electrical supply to affected customers. I have been here seven years, there is never a typical day at work. I’m always learning and growing in my job. — Mr Chan Hong Jiang, principal engineer, Singapore Power He is appreciative that his wife, Candy Ho, 29, a financial planner, supports his “unpredictable and challenging work hours”. “Occasionally I have to work at night and during weekends to handle emergency repairs or electricity supply shutdowns which take place only when the customer premises are empty,” he says. “My wife is very understanding and offers a lot of encouragement and support. This spurs me on to complete my work quickly and safely so that I can go back to my family as soon as possible.” His role model is his 62-year-old father, Mr Chan Teck Chua, whose work attitude, despite minimal education, was exemplary as an auxiliary salesman. “My father, a quiet and humble man, has been a good role model for me,” he says. “Although he did not receive much education and did not have a well-paying job, he worked very hard and lived frugally to provide for the family, something which he did very well and with much pride. I am trying to do the same for my wife and, in the future, for my kids.” Mr Chan’s work philosophy is delivering quality work without looking at the clock. PHOTO: CHONG JUN LIANG
