SP Energy HubAnnual ReportReliabilitySustainabilityInnovation All charged up for a career in engineering RELIABILITY When Executive Engineer Lim Kai Herng took up SP’s Mid-Term scholarship 5 years ago, he was motivated by a huge sense of pride, knowing that his work will help ensure reliable power supply to all residents and businesses in Singapore. The 27-year-old now leads a team of technical officers and technicians to maintain and renew high-voltage equipment and power cables. We caught up with Kai Herng to learn about his role, responsibilities, and motivations at SP. Tell us more about your current role. As a Distribution Network engineer, my work entails equipment maintenance and renewal. We are also the first responders on the ground when there is a power disruption. Executive Engineer Lim Kai Herng guides his colleague, Engineer Lim En Ping, as they carry out switching work at a substation. What is your most memorable achievement to date? When I first started as an engineer, my team and I were tasked to upgrade the existing 6.6kV network equipment at the western part of Singapore. Some of them are at least 20 to 30 years old and did not have in-built remote control and monitoring functions. With advancements in technology, we are now able to retrofit existing equipment to “send” information to our control centre. With the upgrade, power supply can be restored more quickly in the event of disruption. The team successfully completed this project in early 2020 – it is a milestone that I am very proud of! What are some of your biggest challenges at SP and how did you overcome them? As electricity and gas networks are critical infrastructure, close customer engagement for timely equipment and network maintenance becomes even more important. One of the key challenges is the rounds of discussions and negotiations with customers to schedule electricity supply shutdowns, for maintenance works to take place. In order to minimise disruption and inconvenience to customers we need to offer flexible solutions such as staggering shutdown times or providing alternate electricity supply during maintenance work.  Kai Herng cited the importance of strong camaraderie and teamwork. “It is no doubt a  heavy responsibility, but our unwavering focus on keeping Singapore lit keeps us going!”   This article was first published in BrightSparks Magazine February 2021.

This charge varies for different load requirements and is categorised as follows: [a) Development Without Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from both the High Tension [HT) and LT networks, which includes the cost of service cables. For individual consumers without substations, the cost of LT service cable for the same capacity may vary widely depending on their locations with respect to the nearest LT mains. These consumers are not the sole beneficiaries of the extension of the LT network. To achieve a greater degree of equity in terms of cost for these general consumers, a standard cost approach is adopted by grouping consumers with similar supply requirements. The average global cost per kVA is determined based on past statistics. For example, this category of consumers which comprises mainly landed residential owners applying for the same applied load, will pay the same standard connection charge regardless of the location of their premises from the existing LT network. [b) Development With Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from the HT network and the cost of service cable. The cost of tapping supply from the HT network refers to the cost of cables and consumables used in setting up a new distribution substation. It excludes the cost of shared network assets such as switchgear, transformer and HT network cables. The cost is spread to all new consumers proportionally on a per kVA basis. For consumers with substations, their supply intake point is usually adjacent to the substation, which requires a service cable of approximately 15m in most instances. Therefore, the standard cost of service cable is computed based on a length of 15m. Consumers shall pay the additional cost for service cable exceeding 15m. In addition, consumers shall also pay for those dedicated assets, such as switchgear and transformers, which are serving them and do not benefit others.

For longer lengths, additional charges shall apply. Standard charges are only applicable to consumers who are connected to the shared network. Standard charges are not applicable to consumers where the network extension is unlikely to be shared by others. Some of these include supply to HDB premises, premises involving installation of bigger capacity cable in order to overcome the excessive voltage drop, temporary work sites, public installations and offshore island premises. These consumers will be required to pay for the full connection network cost, based on user-pay principle, as they are the main beneficiaries. B2 Service Connection Charges for HT, EHT and UHT Supply Consumers taking HT, EHT and UHT supply shall pay the cost of the service connections to their intake equipment including cables, associated equipment and facilities to effect the connection of consumers’ equipment to SPPA’s substation/network. The service connection shall cater for single contingency. Consumers requesting for additional level of contingency that exceeds the single contingency standard are required to pay for the full cost of such provision. B3 Dedicated Network/Substation The developer or consumer shall pay the full cost of all associated equipment and facilities under a dedicated network/substation scheme for which the network capacity is intended to serve the developer’s development or consumer’s premise(s) exclusively. A substation comprises land, building, electrical equipment and associated cables. A substation which serves a development or premise has to be provided and paid for by the developer or consumer. As the capacity of electrical equipment is lumpy, the substation may have excess capacity. The developer or consumer will carry the cost of this excess capacity which cannot be avoided. As this substation is required to serve mainly the development’s or consumer’s load, it is considered a dedicated substation. To reduce cost, a developer or consumer can choose to let SPPA bear the cost of the electrical equipment and associated cables, thus making the network/substation a nondedicated one. In return, SPPA must be allowed to allocate the excess capacity to other consumers. Even after the excess capacity is allocated, SPPA shall return the capacity to the developer or consumer if his demand grows later provided existing allocated capacity to other consumers can be diverted. The latter provision shall also apply to the decommissioning of the substation. At present, most substations provided by developers or consumers are non-dedicated substations.

These are consumers who choose to buy electricity from SP Group at the regulated tariff. 7 The Uncontracted Capacity Charge (UCC) applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity. UCC applies to: (a) Normal customers without embedded generation; (b) Customers with embedded generation who require top-up supplies and opt to summate their kW output from embedded generation and kW demand from the network (i.e Summation Scheme) for determining maximum demand; and (c) Customers with embedded generation who require top-up supplies and opt to cap their power demand in kW drawn from the network (i.e Capped Capacity Scheme or Extended Capped Capacity Scheme). The UCC applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the contracted capacity and shall be limited to 20% of the Contracted Capacity. 8 For Capped Capacity Scheme (CCS), the Uncontracted Standby Capacity Charge (USCC), at 5 times of Contracted Capacity Charge, applies in the event that the demand in kW (measured by the power meter) drawn from the network exceeds 120% of the contracted capacity for a duration of more than 10 seconds continuously. 9 For Extended Capped Capacity Scheme (ECCS), the 2-tier Uncontracted Standby Capacity Charge (USCC) applies as follows: • Tier 1: 5 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 120% and up to 200% of the contracted capacity for a duration of more than 100 seconds continuously. • Tier 2: 12 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 200% of the contracted capacity for a duration of more than 10 seconds continuously. 10 For both CCS and ECCS, the consumer shall at its own expense, install and maintain Load Limiting Device, in accordance with requirements that the Transmission Licensee may stipulate from time to time. * Based on power factor of 0.85 Notes On Use-of-System Charges Effective from 1 April 2018 1 Supply Categories The Use-of-System [UOS) Charges shall be paid for electricity transmission services at each metered intake supply point in accordance with the voltage at which a consumer receives the electricity supply. The UOS Charges are applicable for the following categories of supplies : • Low Tension [LT) Supplies at 400V/230V Supply to Low Tension-Small Consumer Supply to Low Tension-Large Consumer • High Tension [HT) Supplies at 22kV and 6.6kV Supply to High Tension-Small Consumer, whose Contracted Capacity is less than 1,700 kW per month at each metered intake supply point. Supply to High Tension-Large Consumer, whose Contracted Capacity is at least 1,700 kW per month at each metered intake supply point. • Extra-High Tension [EHT) Supplies at 66kV Supply to Extra-High Tension Consumer • Ultra-High Tension [UHT) Supplies at 230kV Supply to Ultra-High Tension Consumer • Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. 2 Low Tension Supplies 2.1 Low Tension Small Consumer LT supplies [in kWh) to all non-contestable LT consumers are metered on a monthly basis. A flat per kWh UOS rate is levied at each metered intake supply point. These are consumers who choose to buy electricity from SP Group at the regulated tariff. 2.2 Low Tension Large Consumer LT Supplies to these contestable consumers are metered on energy (kWh) on a halfhourly time-of-day basis. The respective per kWh charges shall be levied at a “Peak” and an “Off-peak” period for the energy supplied at each metered intake supply point. 2.2.1 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 2.2.2 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3 High Tension, Extra-High Tension and Ultra-High Tension Supplies For HT (i.e. HT Small and HT Large), EHT and UHT Supplies, UOS Charges shall be levied at each metered intake supply point as follows : a. Contracted Capacity Charge; b. Peak Period Charge; c. Off-peak Period Charge; d. Reactive Power Charge; e. Uncontracted Capacity Charge, and f. Uncontracted Standby Capacity Charge (applicable to consumers with embedded generation who opt to cap their power demand drawn from the network). 3.1 Contracted Capacity Charge 3.1.1 The Contracted Capacity Charge is a monthly charge payable in any month for the Contracted Capacity at each intake supply point of a consumer. The Contracted Capacity shall be the supply capacity (in kW), which is requested by the consumer for that intake supply point. For the avoidance of doubt, and without prejudice to paragraph 3.1.3 herein, the consumer shall not be allowed to reduce the declared Contracted Capacity upon the signing of the Consumer Connection Agreement / Supply Agreement, notwithstanding the fact that the energisation of the new supply has still not taken place. 3.1.2 For a new connection, consumers are subject to a binding period of 5 years from the target date or the commissioning date for SPPA’s plant and equipment, except for the service cable, whichever is later. During the 5-year binding period, no reduction to the Contracted Capacity is allowed. For new HT, EHT and UHT connections, the minimum Contracted Capacity for each intake supply point is as follows : HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 1,700 kW, 12,751 kW, 25,501 kW, 85,000 kW. During the first year of the 5-year binding period, requests for intermediate incremental steps of Contracted Capacity may be made before the full Contracted Capacity is implemented. The first step shall be at least one quarter ( 1 /4) of the consumer’s requested full Contracted Capacity at each intake supply point. 3.1.3 After the initial 5-year binding period, the consumer may, by giving at least 10 business days’ notice in writing, reduce his Contracted Capacity at each intake supply point subject to the following minimum values: HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 850 kW, 6,375 kW, 12,750 kW, 42,500 kW. Any such reduction in Contracted Capacity shall be subject to a 1-year binding period from the effective date of the revised Contracted Capacity, i.e. the consumer shall not be entitled to make any further reduction in the Contracted Capacity within one year following any such reduction.

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. Every single case is different, requiring both tools and thinking. That is the challenge that I love.” — 13 June 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks Lighting the way: Following in his father’s footsteps to keep S’pore’s power grid running 24/7 How this technical officer and robot SPock hunt hazards to protect Singapore’s power tunnels

Impacting people’s lives Singapore Power engineer Thiruchelvam Ranjan loves what he does because the outcome is tangible and necessary At a glance n n n About 2,400 technical professionals required by 2020. Electricity sales are expected to grow by more than 30 per cent over the next decade. Less than 1 minute per customer a year is the average interruption time, making Singapore’s electricity grid one of the most reliable in the world. by wong sher maine In hIs six years with singapore Power (sP), Mr Thiruchelvam Ranjan has held three job portfolios. he has also added a significant achievement to his resumé — he was part of a team that set up a substation — and is being groomed for leadership. The sP scholar and principal engineer says: “I underwent a rigorous graduate development programme during which I was posted to various departments. Besides giving me an understanding of many aspects of the organisation, these rotations also helped me to feel the pulse on the ground, understand the culture of the organisation, and build a strong social network.” The 32-year-old became interested in the power sector during his final year at the national University of singapore, where he earned a bachelor’s degree in engineering, specialising in electrical engineering. he says: “Power is an important and necessary part of everyone’s lives. singapore’s economy and all modern day activities are enabled by electricity, and our networks are amongst the most reliable worldwide.” his career choice was partly inspired by his engineer father. “My father made me realise the impact engineers make on people’s lives,” says Mr Ranjan. “Also, as a young child I would often see him take things apart and put them back together. In today’s world where it’s easier to replace than repair, he made me appreciate and take good care of what I had.” his mother also played a crucial role in shaping who he is today. “Mum was a teacher, and she taught me to question everything. This is something which I constantly apply when I was a student and now as an engineer.” Under sP’s graduate development programme, he has enjoyed a diverse range of jobs. he started off as a network management engineer helping to ensure that the network delivering power to customers is in tip-top condition. Then, in risk management, he learnt to effectively manage sP’s risk exposures. he is currently a project engineer within sP PowerGrid’s network development division where he works on developing singapore’s electricity network, installing and renewing network infrastructure to meet the increasing power demands and connecting new customers to the grid. One of his professional highlights was when he helped to set up the 66kV Rangoon substation, to meet growing demand and strengthen the power network in the central part of singapore including areas like Toa Payoh and Bishan. “We conduct voltage tests, equipment My colleagues comprise a mixture of industry veterans and young talents, but they all have one thing in common — a deep rooted sense of pride in what they do. They have inspired me to always give my best at work, because what I do impacts lives. — Mr Thiruchelvam Ranjan (right), principal engineer, Singapore Power functionality and safety checks before the substation goes live. Each successfully commissioned project adds to the reliability of singapore’s power network, and I am proud to have contributed to this effort.” he adds: “As an sP engineer, no two work days are identical. The challenges I have had to handle include managing network projects, addressing customers’ concerns and responding to power outages.” he was selected to attend the 2013 Young LEADERs! programme conducted by Business Leadership Centre of the Temasek Management services Group, where he honed his strategic thinking and business leadership skills. he is now in charge of organising sP Family Day 2014. he says: “This is a massive event with a lot of logistical and manpower planning involved. I look forward to the challenge of providing an enjoyable and memorable experience for 10,000 staff and their loved ones.” his experience and accomplishments at sP stand him in good stead for a Professional Engineer certification, which is the profession’s highest standard of competence. Mr Ranjan says: “The experience and knowledge that I have gained from working in sP will be instrumental towards achieving this goal.” he loves what he does because the outcome is tangible and necessary. “Every day, the work we do and projects we handle help to grow singapore’s network and connect customers to the grid, powering their activities at home, work and play. In many ways, PhoTo: Wee TY what we do at sP is an integral part of nation building and enhancing lives.” Mr Ranjan is in good company. “My colleagues comprise a mixture of industry veterans and young talents, but they all have one thing in common — a deep rooted sense of pride in what they do.
