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.

Media Release SP Group to Green Electricity Substations for a More Sustainable Future Rooftop solar panels to be installed at 37 substations by 2025, generating enough electricity to power 4,500 four-room Housing Development Board flats for a year This is the latest in a series of green initiatives to maximise substation infrastructure for sustainable outcomes Singapore, 8 November 2022 – SP Group (SP) announced that it will be installing rooftop solar panels at 37 electricity substations by 2025, with a total installed capacity of 15.7 megawatt-peak (MWp). This is the latest green initiative by SP to optimise substations with low-carbon capabilities and achieve our national sustainability targets. When completed, the combined solar power capacity of 15.7 megawatt-peak (MWp) will deliver up to 21,000 megawatt-hour (MWh) of renewable electricity into Singapore’s electricity network annually – enough to power more than 4,500 four-room Housing Development Board (HDB) flats for a year. The substations were selected for their suitability to install solar panels and generate solar energy. The rooftop solar installation will be done across three phases. The first phase of six substations with a combined solar power capacity of 7.1 MWp will be completed by end2023 – with the very first substation at West Jurong Island to have its rooftop solar system operational by July 2023. This will be followed by the second batch of 12 substations with a combined capacity of 6 MWp by mid-2024 and the final batch of 19 substations with a combined capacity of 2.6 MWp to be completed by end-2025. Each substation will have an installed capacity not exceeding 1 MWac (Megawatt of AC Power). The initiative is part of the Singapore’s plans to incorporate more renewable energy in its energy mix and will contribute towards EMA’s target of installing at least 2 gigawatt-peak (GWp) of solar deployment by 2030 1 . It will also support Singapore’s long-term ambitions to achieve net-zero emissions by 2050. Mr Ngiam Shih Chun, Chief Executive of the Energy Market Authority (EMA), said, “Solar is Singapore’s most viable renewable energy source. As part of our efforts to tackle climate change and decarbonise the power sector, we will need to maximise solar deployment on all available land and space in Singapore. With SP Group’s deployment of solar panels on its network of power substations, this brings about an intuitive use of the limited space available in addition to other innovative deployments such as on temporary vacant land and water bodies.” Mr Stanley Huang, Group CEO, SP Group, said, “In supporting the energy transition, we are keen to leverage our electricity substations and roof spaces to contribute clean energy for Singapore. We will continue to work closely with EMA to optimise our existing electricity infrastructure and assets to provide reliable and efficient electricity supply, and to support developments to meet Singapore’s sustainability targets.” SP has been working on various green initiatives to leverage electricity substations for sustainable outcomes. In August this year, EMA and SP jointly announced a pilot to test the viability of installing a thermal energy storage system at the George Street substation. The pilot also includes the installation of additional chillers to support future expansion of the Marina Bay district cooling network, bringing sustainable cooling to more buildings. This is a first move to locate an ice thermal storage facility outside a district cooling plant. - End - 1The Future of Singapore’s Energy Story – EMA About SP Group SP Group is a leading utilities group in the Asia Pacific, empowering the future of energy with low-carbon, smart energy solutions for its customers.

SP Group partners BCG Energy on solar project in Vietnam � MON, AUG 02, 2021 - 1:20 PM YONG JUN YUAN �junyuany@sph.com.sg �@JunYuanBT SP Group (SP) and BCG Energy, a wholly-owned subsidiary of Bamboo Capital JSC, have formalised a joint venture (JV) to invest in rooftop solar and other renewable energy projects in Vietnam. In a press statement on Monday, SP said that it will own 49 per cent of the JV, while the wholly-owned subsidiary of Bamboo Capital JSC will own 51 per cent. The JV will have an initial target of 500 megawatts (MW) of rooftop projects by 2025, contributing to Vietnam's target of having 30 per cent of its electricity generated through renewable energy sources by 2030. As part of the JV's rst rooftop solar project, it will work with Vinamilk, Vietnam's largest dairy production company, to install a combined 25MW of rooftop solar power across nine factories and seven farms. The installation will generate 35,000 megawatt-hour of clean electricity annually, enough to power approximately 20,000 households in Vietnam. It also amounts to a reduction of 32,000 tonnes of annual carbon emissions, equivalent to taking approximately 7,000 cars o the road. The JV will also acquire 28MW of operational rooftop solar assets across eight commercial and industrial sites located in South and Central Vietnam. BCG Energy chief executive o cer Tuan Pham noted that Vietnam completed and connected more than 100,000 rooftop systems to its grid and that there is strong growth potential in this market segment in Vietnam as it develops. "We believe this will promote the use of clean energy in manufacturing companies and contribute to the sustainable growth of the economy," he said. SP chief executive o SP as it steps into the Vietnamese market. cer Stanley Huang noted that the partnership is a key milestone for "Our combined expertise and ambition in renewable and sustainable energy solutions will o er customers more options and encourage their transition to clean energy sources," he said. The announcement comes after both sides signed a memorandum of understanding (MOU) in May this year to invest in renewable energy projects in Vietnam. The MOU provided an exclusive right for SP to acquire up to 49 per cent of Skylar Joint Stock Company (Skylar), a subsidiary of BCG Energy which specialises in the development and deployment of solar assets.

BUILDINGCAREERS / Employer branding key to firm’s success BY REICO WONG C OMPANIES are known to devote much attention and resources to building up their identity and reputation among their business partners and clients, but many often neglect the other side of the coin – branding themselves within the company. After all, employees can be said to be a corporation’s most important stakeholders, without whom it would not be possible to carry out the company’s business. And, given today’s tight labour market where there’s a fierce battle for talent, developing a strong internal brand, or employer brand, can go a long way in helping companies attract and retain top personnel, said human-resource experts. Specifically, companies that invest in positioning themselves as an employer keenly interested in the development and welfare of its employees, and carry out these promises, have seen success. SP Services is a case in point. Mr Melvin Wong, 28, an assistant manager at SP Services’ project-management office, said that he is motivated to stay on with the company after 2 1 /2 years because the management actively creates training and development opportunities for its staff, not just leaving it to chance. While he joined the company as an executive in the firm’s business-development arm, Mr Wong was given the opportunity to move to the regulatory-affairs department just eight months later. He spent 1 1 /2 years there learning about macro issues affecting the company, such as regulatory policies laid down by the Government, and managing corporate profits and losses. Then, just last month, he joined the company’s project-management team on rotation. “Supervisors will have regular sit-down sessions with staff, ask you what you see yourself doing in three to five years’ time, and groom you for it if it’s aligned with organisational goals,” said Mr Wong. “I’m deeply appreciative of this as not all companies have the appetite to let staff explore opportunities laterally. Most prefer to hire individuals with experience in a particular role.” He added that his company strongly encourages work-life balance, and is “very open” to staff coming in slightly later, if necessary, as long as they deliver on their work. “It’s a big relief that they are so flexible as I’m very busy preparing for my wedding in December,” said Mr Wong, who also manages to find time to pursue hobbies like ballroom dancing after work. Besides that, SP Services has in place a strong telecommuting scheme. Its field team starts its assignments from home, instead of having to report to the office first. Technicians and meter readers, for example, receive their assignments through personal digital assistants, saving at least two hours each day in travelling time. A range of employee-support programmes has also been rolled out, including financial assistance for renovation, and subsidies for children’s education, gym memberships and personal-development courses. Mrs Jeanne Cheng, managing director of SP Services, said these are all part of the company’s strategy to help staff feel happy, fulfilled and cared for. “A company’s identity, image and reputation are reflected not only through its products and services. It has to start from within and resonate first with its employees,” she said. “Employees who feel a sense of belonging, ownership and pride will make it their personal mission to be ambassadors of the organisation – not because it is their job, but because they truly feel they are part of the company and want to make a valuable contribution.” This ultimately translates into better customer service, increased customer satisfaction and confidence, and strengthens brand equity, Mrs Cheng added. Mr Josh Goh, assistant director of corporate services at human-resource firm The GMP Group, noted that company culture plays a critical role in establishing an attractive employer brand. “Having a strong corporate reputation does not equate to a strong employer brand,” he said. “Internal practices and policies should be reviewed regularly so that they are kept up-to-date with changing times.” Ms Shauna Li, principal consultant at BrandHub, pointed out that employer branding is not just the responsibility of the human-resource department. The human-resource team needs to have strong connection with the operations team and to have deep understanding of both operational requirements and employee needs. Managers also need to be roped in to ensure that employee-centric policies are carried out and that flexibility is given, she said. “Keeping in touch with company alumni is also very important in terms of word-of-mouth referrals about the company to future employees and potential clients,” said Ms Li. “Opportunities for current staff to interact with alumni is important so that they can learn more about the history of the firm and develop a stronger sense of belonging.” reicow@sph.com.sg Branding: 品 牌 推 广 工 作 pĭn pái tuī guăng gōng zuò Work-life balance: 工 作 与 生 活 的 平 衡 gōng zuò yǔ shēng huó de píng héng Sense of belonging: 归 属 感 guī shŭ găn Referrals: 介 绍 jiè shào THIS SPONSORED PAGE IS BROUGHT TO YOU BY THE GMP GROUP

Electrical Installation An electrical installation refers to any electrical wiring, fitting or apparatus used for the conveyance and control of electricity in any premises. A solar PV system installed within such premises forms part of the consumer’s electrical installation and should comply with the requirements stipulated in the Electricity Act (Cap. 89A), the Electricity (Electrical Installations) Regulations and the Singapore Standard CP5 Code of Practice for Electrical Installations. 1 The point of connection refers to the point at which the solar PV system is connected directly or indirectly to SP PowerAsset’s substation. December 2022 3 Solar PV – User Guide for Non-Residential Consumers All electrical work for an electrical installation, including a solar PV system, must be undertaken or carried out by a Licensed Electrical Worker (LEW). Such electrical work includes new wiring, rewiring and extensions which have to be tested before the supply is turned on. When consumer needs any electrical work to be done at his premises, he is advised to check that the person whom he intends to engage to undertake or perform the electrical work has a valid electrical worker licence issued by the Authority. It is an offence for a person: i. To carry out or caused to be carried out any electrical work unless he holds a valid electrical worker licence; or ii. To engage knowingly any person who is not a licensed electrical worker to carry out any electrical work. For more details, you may wish to refer to ELISE website for the list of LEW. Electrical Installation Licence LEW will need to apply for an Electrical Installation Licence for the installation if the usage or operation of an electrical installation exceeds 45 kVA of approved load for non-domestic purposes and for multi-metered premises. Electrical installations are licensed to ensure that owners/users of certain electrical installations engage a LEW to take charge of and maintain their electrical installations for reason of safety. A grid-connected solar PV system forms part of the consumer’s electrical installation. A new solar PV system will be covered under the existing electrical installation licence upon connection to the installation by the LEW taking charge of the electrical installation. Safety requirements Currently under the electrical installation licensing scheme, the consumer’s appointed LEW is required to carry out safety inspection and certification of the electrical installation, including the solar PV system, according to the conditions specified under the electrical installation licence. Solar PV systems require regular inspection and maintenance to ensure that the system remains efficient and safe for operation. In most cases, equipment manufacturers will provide maintenance guidelines for their specific components. It is important to ensure that the maintenance requirement is carried out according to the recommendation and certified by the LEW. December 2022 4 Solar PV – User Guide for Non-Residential Consumers 4. Connection Requirements If you intend to connect and operate your solar PV system in parallel to the power grid, your appointed LEW will have to complete the online Application Form and submit the following documents to SPS via Singapore Power (SP) eBusiness Portal: • Document Checklist and Declaration of Compliance to SP PowerGrid’s (SPPG) Technical Requirements • Application for Net Export Rebate Form • Letter of Consent • PQ Compliance Report • Inverter(s) Specifications • Solar Panel(s) Specifications • Inverter(s) Type Test Reports (Harmonics, Flicker, DC Injection) • Single Line Diagram (from PV system to Point of Common Coupling (PCC) • PSO Data Form (only applicable for solar PV system 1 MWac and above) • Certificate of Compliance (only applicable for licensed installation who are eligible to appoint their LEW to commission the solar PV system) • Commissioning Declaration (only applicable for licensed installation who are eligible to appoint their LEW to commission the solar PV system) Thereafter, your appointed LEW will have to consult SPPG on the connection scheme and technical requirements. For High Tension and above (6.6kV and above) consumers with embedded IGS / generation, you will need to choose one of the 3 backup schemes (full or partial) required: (1) Summation Scheme; (2) Capped Capacity Scheme; or (3) Extended Capped Capacity Scheme You will need to sign a Supplemental Agreement with the Transmission Licensee to reflect your choice of backup scheme for the service connection.

Market Settlement The process required and the amount of payment received for selling excess solar electricity back to the grid depends on the size of the solar PV system and contestability status of the consumer. An overview of the available payment schemes can be found on EMA’s website. Consumers with embedded solar PV systems will be given ‘net settlement’ of the energy component. This means that consumers are either charged for their net consumption or paid for their net generation within each trading period. 5.1 Solar PV system below 1 MWac Non-contestable consumers (NCCs) For Low Tension (LT) NCCs with less than 1 MWac embedded solar PV systems, the solar energy produced is first offset by their consumption of that premise. Should there be excess solar energy to be exported back to the grid, they will receive payment (the prevailing low-tension electricity tariff minus grid charge) from SP Services (SPS) by way of credit adjustment to the monthly electricity bill. The quarterly revised low-tension electricity tariffs can be found on SP Group’s website (www.spgroup.com.sg). Contestable consumers (CCs) For CCs who wish to be paid for the excess electricity sold to the grid, they can register with SPS under the Enhanced Central Intermediary Scheme (ECIS). Under this simplified arrangement, they will be paid the weighted average nodal price through SPS, for the selling of excess solar electricity back to grid. SPS will act as a central intermediary, by passing through the payment and relevant market charges to consumers. Such consumers can either choose (a) to install a meter to accurately measure the solar electricity generated, or (b) to estimate their solar generation. For option (a), consumers will need to install the relevant metering arrangement at each generation point. More details on the meters can be found in Section 8, AMI Meter Charges. For option (b), the solar generation will be estimated based on the Solar Generation Profile (SGP) 2 for the calculations of the relevant payment and market charges. Consumers need not install any meters. For CCs who do not wish to be paid for the excess electricity sold to the grid, they do not need to register with EMC as Market Participant or with SPS under the ECIS. They 2 The SGP is approved by the Energy Market Authority (“EMA”) and is based on factors such as Singapore's historical average solar irradiance from 7am to 7pm. This is standardised for all consumers with embedded solar PV systems and will be updated by EMA as new information becomes available. December 2022 10 Solar PV – User Guide for Non-Residential Consumers will not be eligible for the ‘net settlement’ scheme and also not be subjected to the applicable market charges. 5.2 Solar PV system 1 MWac and above but below 10 MWac There are various options for CCs to sell excess electricity back to the grid: i. Register with SPS under the Enhanced Central Intermediary Scheme. Under this simplified arrangement, they will be paid the weighted average nodal price through SPS, for the selling of excess solar electricity back to grid. SPS will act as a central intermediary, by passing through the payment and relevant market charges to consumers. Such consumers can either choose (a) to install a meter to accurately measure the solar electricity generated, or (b) to estimate their solar generation. For option (a), consumers will need to install the relevant metering arrangement at each generation point. More details on the meters can be found in Section 8, AMI Meter Charges. For option (b), the solar generation will be estimated based on the SGP for the calculations of the relevant payment and market charges. Consumers need not install any meters. ii. Register with the EMC as Market Participant. Under this existing arrangement, the CCs are required to register with the Energy Market Company (EMC) as Market Participant (MP); and to register their Solar Generation Facility, in order to receive payment for the selling of the excess solar electricity back to the grid. They will be paid nodal price for the selling of excess solar electricity back to the grid, and are subjected to the applicable market charges. Such consumers can either choose (a) to install a meter to accurately measure the solar electricity generated, or (b) to estimate their solar generation. For option (a), consumers will need to install the relevant metering arrangement at each generation point. More details on the meters can be found in Section 8, AMI Meter Charges. For option (b), the solar generation will be estimated based on the SGP for the calculations of the relevant payment and market charges. Consumers need not install any meters.

Register with EMC as Market Participant (IGS non-exporting). For consumers with embedded solar PV systems below 10 MWac who are not eligible for option (i) or (ii) and will not be selling any electricity back to the grid, they can undergo a streamlined market registration process and pay EMC an estimated fixed charge determined by EMA. This fixed charge will be based on the SGP and the historical average rates of the respective charges. For options (i) and (ii), CCs would need to register their load and generation accounts under the same entity with SPS. A summary of the market payments and charges for the respective options can be found in the table below.

For example, on a rainy or cloudy day, they will be consuming more electricity from the grid as their solar PV system may be generating little or no electricity. However, as the SGP is a fixed output throughout the year, it would indicate that the solar installation is still generating. Hence, before deciding on the type of backup scheme and whether to opt for SGP or meters, consumers should assess their consumption profile and operational needs. They should also consider carefully the costs and benefits, including the risks and uncertainties due to weather variability. Reactive Power Currently in the Transmission Code, High-Tension consumers would be required to implement power factor correction measures, if deemed necessary by the Transmission Licensee, to maintain a power factor of no less than 0.85. This is because a load with high reactive power will require more current-carrying capacity from the grid. For solar consumers who opt for SGP, there may be instances where they are penalised due to differences between active power output based on the SGP and active power output based on actual generation. This affects the calculation of gross load, on which reactive power penalties are determined. Hence, consumers who opt for SGP may risk incurring reactive power penalties when actual generation values differ from SGP values. If so, consumers can opt out of the SGP and install physical meters to accurately measure the active power output. 6. Intermittency Pricing Mechanism Given the intermittent nature of solar PV, reserves from conventional power sources are required to ensure system stability. For example, cloud cover or shadows may cause solar PV output to drop quickly, which requires the need for reserves to make up for the shortfall. Without the back-up through reserves sources, consumers are exposed to the risk of power disruptions, which happened in other countries with large amounts of intermittent generation. December 2022 15 Solar PV – User Guide for Non-Residential Consumers To ensure the sustainable growth of solar, a balance has to be struck between the benefits of solar generation and the intermittency costs it imposes on the system. Hence, it is appropriate to consider a mechanism, Intermittency Pricing Mechanism (IPM), to allocate the fair share of reserves costs to solar. Upon its implementation, the IPM will apply to all IGS, except for certain groups which the EMA had previously indicated that would not be subject to the IPM. The groups include: a. Residential consumers with embedded solar PV systems below 1 MWac; and b. Non-residential consumers with embedded solar PV systems connected to the system on or before 31 January 2018, unless (i) they retrofit their IGS systems such that re-commissioning by SP PowerGrid would be required in the process; or (ii) 25 years from the commissioning date of their existing IGS systems, whichever occurs earlier. More details on the IPM can be found in EMA’s Consultation Paper. 7. Monitoring Requirements With the expected increase in solar PV systems in Singapore, the Power System Operator (PSO) would need to manage the intermittent nature of such sources to ensure that the security and reliability of the power system is not compromised. Most importantly, PSO also needs to ensure that sufficient reserve capacity is available to respond to sudden fluctuations in solar output. Hence, PSO shall require solar PV systems with an installed capacity of 1 MWac and above at each site/facility to provide the Active Power output (AC-side) of its solar PV system(s), sampled at one-minute intervals and solar irradiance from sensor installed in close proximity to the PV panels. For more detailed technical requirement, please contact EMA at EMA_PSO_EMS@ema.gov.sg. Localised Network Limit As there may be physical constraints of each network ring, there could be a limit to the amount of solar PV systems that the network circuit can support. Therefore, depending on the limitations in that area, the permissible capacity of solar PV systems in each location may differ. Hence, parties who wish to invest in solar PV systems should check if there are possible network constraints in their preferred locations, before making their investment decisions.

AMI Meter Charges This section is only applicable to consumers who register their embedded solar PV systems with SPS under the Central Intermediary Scheme, or with EMC as a Market Participant. The owner of the generation facility (i.e. solar PV system) is the Meter Equipment Service Provider (MESP) for the meter installation associated with it.
