Media Release Singapore Power Sets Up Singapore Institute Of Power And Gas To Provide Training To The Power And Gas Sector Singapore Power (SP) will set up the Singapore Institute of Power and Gas (SIPG) to provide training courses for the Power and Gas sector.   The setting up of SIPG is part of the industry-led efforts by SP, with support from the Government, to establish a one-stop training centre to meet the needs of the Power and Gas Sector.   SP has taken the initiative to follow up on the Power Sector Manpower Taskforce (PSMT)’s recommendations and support the manpower training needs in the Power and Gas Sector. Earlier in April 2014, a Memorandum of Understanding (MOU) was signed between key players in the Sector to come together on the Centralised Training Institute initiative. This was the precursor to the formation of SIPG.   Mr Quek Poh Huat, Senior Adviser of Singapore Power Limited expressed that: “The setting up of SIPG signals the importance that the industry places on the training of its workforce, and reflects the strong commitment of industry players to work together to provide relevant courses for the Sector. SIPG will place emphasis on retaining the expertise in the industry and transferring the know-how to the next generation of professionals. SIPG will also have the potential to develop into a regional training centre and sharing our knowledge with other countries in the region.”   The setting up of the SIPG is strongly supported by the government. The Energy Market Authority (EMA) will be co-funding the initial set-up of SIPG with a grant. This will go towards the setting-up and development of the initial courses for the industry, as well as in providing supporting facilities such as training equipment and tools.   Mr Chee Hong Tat, Chief Executive of EMA said: “The setting up of SIPG received strong support from power industry players. EMA will continue to work with the industry to build up a strong Singaporean core of technical professionals for the power sector.”   Targeted Launch Date for Courses SIPG plans to launch the first courses for the industry in 2015. The courses will be based on the National Energy Competency Framework which has been established by EMA. The courses will cover technical and in-depth training programmes on Power Plant Operations and Asset Management. Broad-based overview programmes for the industry are also being developed in consultation with the industry.   Issued by: Singapore Power Limited 10 Pasir Panjang Road #03-01 Mapletree Business City Singapore 117438 Co.

THE STRAITS TIMES BRANDED CONTENT How this real-life Captain Planet is combating climate change Principal engineer Xcel Lai and his colleagues at SP Group (SP) are helping the nation achieve decarbonisation one solar panel at a time Part of principal engineer Xcel Lai’s job is to identify and optimise underutilised spaces so that solar panels can be deployed to generate renewable energy. PHOTO: SP GROUP PUBLISHED MAY 3, 2023, 4:00 AM SGT While great strides have been made to advance the adoption of solar energy, there is still tremendous work to be done and hurdles to overcome. To tackle climate change and decarbonise the power sector, Mr Xcel Lai, a principal engineer at SP Group (SP) and a member of the company’s Sustainable Energy Solutions team, works with commercial and industrial customers to maximise solar deployment on their properties by identifying and tapping underutilised spaces to generate sustainable, renewable energy for business needs. Mr Lai’s latest project involves installing rooftop solar panels on 37 electrical substations across Singapore, which will generate low-carbon energy of 15.7 megawatt-peak (MWp) annually – enough to power more than 4,500 four-room HDB flats a year. This is one of SP’s latest green initiatives to optimise substations with low-carbon capabilities and contribute towards national sustainability targets. “Green energy is transformational and central to the future of energy. My job is to figure out how to safely and optimally shift our energy supply from our traditional energy sources to more sustainable sources,” shares the 33-year-old. A substation is a part of the power grid infrastructure which enables energy transmission and converts high voltage to low voltage for the end-user. For Mr Lai, the project to “green” the 37 substations exemplifies what it takes for Singapore to progress in her energy journey. The solar panels are slated to be installed on all 37 substations by 2025. This in turn will contribute to Singapore’s ambition to achieve net-zero carbon emissions by 2050. The Energy Market Authority aims to install at least two gigawatt-peak of solar deployment by 2030, equivalent to the annual electrical needs of 350,000 households. Engineering the urban solar roofscape The concept of harvesting the sun’s energy from Singapore’s rooftops sounds straightforward. However, it is not just a matter of mounting solar panels on any available space. In land-scarce Singapore, rooftops may not always be designed to house solar panels. Typically, a project to install solar panels starts with a site feasibility study. Mr Lai visits the site to assess and plan how to install the photovoltaic system which transforms sunlight into electrical energy. “I get to access the usually-hidden service and logistics areas, which can look surprisingly different from what the public sees,” he says. “There are many considerations during a site survey – from the irradiance and shading which is affected by the surrounding buildings and the sun’s angle, to the type and weight-bearing ability of the roof surface. We also need to ensure that the installation conforms to the Singapore Civil Defence Force’s fire safety regulations,” Mr Lai adds. The space also has to be large enough for an efficiently scaled operation. These technical challenges aside, Mr Lai is excited about the prospect of overcoming these constraints to unlock the viability of solar energy at scale. “Carbon neutrality is an achievable goal and Singapore is moving decisively towards this. It is only a question of how fast we are able to transition. This is where my colleagues and I at SP have a chance at making a meaningful contribution to our industry and the planet. While the path to net-zero is an uphill task, we hope to be part of the solution that reduces the pollution, metaphorically speaking.” Sustainability has become a priority for many companies today. Mr Lai and his colleagues from the SP's energy services unit are identifying solutions that would help businesses embed sustainability practices into their operations to accelerate their decarbonisation efforts. These include solar photovoltaic systems, microgrids and battery energy storage systems. Mr Lai shares that it is only a matter of time before Singapore deploys solar panels over most surfaces that are suitable here. PHOTO: SP GROUP Investing in reliable energy generation As a country with limited natural resources, solar energy holds a lot of promise as a source of sustainable energy for Singapore. “Singapore has an abundance of solar energy. Solar energy is clean and has the potential to be integrated into our infrastructure,” says Mr Lai. “It’s our best bet as a green energy solution.” What happens when it rains and gets cloudy? “We can “collect” energy in an energy storage system when the sun is out, and use the stored energy after the sun sets, or during cloudy, rainy days.” SP is supporting the growth of the Energy Storage System (ESS) capacity to manage intermittency from solar energy. Such a system provides quick response when solar installations are affected by cloud cover, making it a reliable source of power. In the future, with more mature battery technology in ESS, solar energy will prove to be even more viable and reliable. Towards a climate-friendly future The sector is going through a massive transformation and it is not enough just to react to the changes. This is why SP is continuing to scale up on solutions that support the Singapore Green Plan 2030. “We are picking up the pace to meet our energy goals. It’s only a matter of time that we will deploy solar panels over most surfaces that are suitable in Singapore,” says Mr Lai. Recently, SP partnered with AIMS APAC REIT (AA REIT) to install photovoltaic systems on six of AA REIT’s industrial, logistics and warehouse properties. This will be one of the largest rooftop solar installations by any Singapore-listed real estate investment trusts. The panels can collectively produce 14,500 Megawatt-hours of renewable energy and avoid over 5,900 tonnes of carbon emissions a year, which is equivalent to taking almost 6,490 cars off the road. Besides solar energy generation, SP is also paving other critical pathways to achieve net-zero carbon emissions, including electric vehicle (EV) charging, centralised district cooling and smart metering. SP has also exported these solutions to overseas markets, including China, Thailand and Vietnam to help countries meet climate goals.

Exempted Wholesaler (Generation) Licence Exempted Generation Licence Application for the wholesaler or generation licence can be made on EMA’s website: http://www.ema.gov.sg/Licensees_Electricity_Licences.aspx 3. 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 Residential Consumers All electrical work for an electrical installation, including a solar PV system, must be undertaken or carried out by a Licensed Electrical Workers (LEWs). 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 All electrical installations used exclusively for domestic purposes except multi-metered premises are exempted from this requirement. Safety requirements Solar PV system requires 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 a LEW. December 2022 4 Solar PV – User Guide for Residential Consumers 4.

Market Settlement An overview of the available payment schemes can be found on EMA’s website. Non-contestable consumers (NCCs) Currently for residential NCCs with solar PV system, 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 tariff can be found at the SP Group website (www.spgroup.com.sg). Contestable consumers (CCs) With the introduction of the Open Electricity Market “OEM”, residential CCs with solar PV system less than 10 MWac, is eligible to sell his excess output through SPS under the Enhanced Central Intermediary Scheme (ECIS). SPS will act as a central intermediary, by passing through the payment and relevant market charges to consumers. Excess solar electricity sold back to the grid will be paid the weighted average nodal price. December 2022 7 Solar PV – User Guide for Residential 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 7, 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. 6. 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_EMA@ema.gov.sg. 7. AMI Meter Charges This section is only applicable to residential consumers who register their embedded solar PV systems under the ECIS and chose to install an AMI meter. 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. However, consumers with embedded generation facility (with installed capacity of less than 10 MWac) may choose to engage SPPG to provide, install and maintain the generation meter. The fees applicable for providing such services by SPPG are shown in the table below: 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.
