SP Group Sustainability Review FY2019/2020 SP GROUP Sustainability Review FY2019/2020 Scope of Review This is the annual sustainability review published by SP Group for the financial year 1 April 2019 to 31 March 2020. The scope of this review covers SP Group’s Singapore-based operations. Sustainability Strategy SP Group’s mission is to deliver reliable and efficient utilities services to enhance the economy and the quality of life of our consumers. This mission is rooted in our value system of commitment, integrity, passion and teamwork. Sustainability is central to our mission and guides us to achieve our mission in a responsible and committed manner. As a leading energy utilities company, we anchor our sustainability strategy around the United Nation’s Sustainable Development Goal (SDG) 7 – to ensure access to reliable, sustainable and modern energy for all. For more information, please refer to https://www.un.org/sustainabledevelopment/energy/ 7.1 Enhance energy access SDG 7 has three key targets: 7.2 Increase renewable energy 7.3 Promote energy efficiency Industry collaboration in energy technology and investment in energy infrastructure are identified as key enablers to meet these targets. We aspire to be a leading utilities company in a low-carbon future and providing energy that is reliable and sustainable is central to this long-term strategy. We recognise that to enable this clean transition, we need to invest in innovative technologies and infrastructure. We also understand that our actions need to extend beyond our own operations, to those of our customers who can create a large share of the impact through their choices and decisions. With this in mind, we have identified three strategic areas that support our actions towards the achievement of SDG 7: (1) Network Reliability, (2) Innovation and (3) Customer Empowerment. Mission: Deliver reliable and efficient utilities services to enhance the economy and the quality of life Network Reliability Value System: Commitment, Integrity, Passion, Teamwork customer empowerment Innovation 02 SP GROUP Sustainability Review FY2019/2020 In addition to helping customers reduce their carbon footprint, SP Group is committed to reducing the environmental impact from our business operations. In 2019, an extensive data collection exercise was completed to calculate the greenhouse gas (GHG) emissions following the principles in the Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (revised edition). FY2019/2020 emissions Absolute, tonnesCO 2 e Intensity, kgCO 2 e/MWh sold Scope 1 25,966 0.54 Scope 2, location based 355,110 7.38 The bulk of SP Group’s GHG emissions in Scope 2 resulted from the dissipated energy emissions from technical losses via the distribution network and the transmission system in Singapore. While these emissions are inherent in the operations of the network, SP Group is committed to identifying opportunities to reduce the emissions from other key business activities that we operate and can influence. Value Add 30 Vision 2030 Reduce Carbon 30 We have set ourselves a “30-30-30” target to add at least 30 per cent value to our customers and reduce our carbon footprint by 30 per cent, by 2030. With FY2018/2019 as the baseline year where applicable, selected performance indicators will be measured and tracked in relation to our material topics of network reliability, innovation and customer empowerment. Our SAIDI performance for electricity network improved to 0.56 minute as compared to 0.87 minute in the previous year More than 29,000 tonnesCO 2 e avoided from our various low carbon solutions offered to our customers In FY2019/2020, our System Average Interruption Duration Index (SAIDI) for electricity network improved to 0.56 minute as compared to 0.87 minute in the previous year. Commonly used as a reliability indicator by electricity companies, SAIDI measures the average outage duration experienced by each customer served. Our improvement reflects the continuous efforts we have put in place to ensure our customers are provided with reliable electricity supply. We have also facilitated the switch for 46 per cent of residential customers and 43 per cent of small business customers in the Open Electricity Market, enabling them to enjoy savings of 20 per cent to 30 per cent off the regulated tariff. Customers also have the option of a non-standard price plan to buy electricity from the wholesale electricity market. The various initiatives that have resulted from our focus on innovation have helped to reduce the carbon footprint of our customers through avoided emissions. In FY2019/2020, the carbon dioxide (CO 2 ) emissions avoided amounted to more than 29,000 tonnes carbon dioxide equivalent (tonnesCO 2 e), which was 19 per cent more than the baseline year of FY2018/2019. 03 SP GROUP Sustainability Review FY2019/2020 Contributing to SDG 7 Targets SDG targets by 2030 Material topic Our key contributions 7.1 Energy Access Ensure universal access to affordable, reliable and modern energy services.

We understand that people and businesses rely on us to provide consistent and reliable power. SP Group aims to deliver a high reliability rate with near-zero downtime. Network reliability will continue to be a key topic to SP Group as we strive to deliver excellence in our service provision and operations. Management Approach Network Maintenance Singapore has one of the best electricity and gas network systems in the world. Despite all our efforts, supply interruption is inevitable. They occur due to various reasons including network failure, damage by third parties, faulty equipment at customer sites or issues with the source of the supply. Electricity Network To minimise occurrence of power failure, SP Group carries out regular maintenance measures. One of the measures is online condition monitoring which checks the network around the clock. Any anomalies detected will trigger a response for the team to carry out rectification works to ensure the continued well-being of the equipment. In 2019, to enhance speed and accuracy in predicting anomalies, we have implemented online condition monitoring for newly installed 230kV and 400kV cable joints, and for all 230kV, 400kV and new 66kV switchgears. We are in the process of doing the same for all 22kV source station’s switchgears, to be completed by 2022. We also carry out physical monitoring every six to nine months. This measures the voltage and equipment condition when the checks are being conducted. If a power failure occurs, we take remediation actions to minimise the impact and downtime. Implemented online condition monitoring for newly installed 230kV and 400kV cable joints, and for all 230kV, 400kV and new 66kV switchgears to enhance speed and accuracy Employees work 24/7 at SP Group’s distribution control centre, the nerve centre of Singapore’s power grid, to ensure supply reliability. 05 SP GROUP Sustainability Review FY2019/2020 SP Group’s mobile generator crew is on standby 24/7. 1. Remote switching 2. Manual switching 3. Mobile generators 4. Cable jointing When a power fault is detected, this first course of action disconnects the affected equipment from the network and reconnects it to an alternative supply source. In 2019, we implemented remote switching capabilities for all 6.6kV distribution networks substations, enabling quicker restoration should a supply interruption occur. This is conducted when remote switching is unable to restore power supply. Power faults in low-voltage networks, such as damage to overground boxes that are used to transmit electricity to customers, are usually resolved through manual switching. These generators are deployed when power faults are reported and are used to provide temporary electricity supply while network issues are being resolved. This is conducted when switching is unable to resolve the power fault and the mobile generators cannot access the substation where the fault has occurred. Manual switching 06 SP GROUP Sustainability Review FY2019/2020 Gas Network SP Group owns and operates the gas network to supply gas to industrial, commercial and residential customers. The high pressure gas transmission system transports the main fuel source for Singapore’s power generation plants. A whole-of-life approach to asset management is adopted to manage risk and ensure that the gas network is developed, maintained and operated in a safe manner. The gas network is monitored round the clock in a system control centre. A Supervisory Control and Data Acquisition (SCADA) system is deployed on the transmission system to avail remote monitoring and operations capability, which enables immediate response to incidents. When incidents occur, response is centrally managed to ensure that performance recovery is quick and directed, and disruption to customers is minimised. SP Group checks the gas regulators regularly to ensure optimal gas supply pressure for customers. Regular inspections and maintenance are conducted on our assets to maintain reliability. An asset renewal programme tracks asset performance and replaces deteriorating assets efficiently. Patrol and leak survey of the pipelines are conducted to detect third party activities and gas leaks respectively. Dedicated planning of assets, selection of materials, project management and strict testing requirements are in place to maintain the integrity of the gas network. This enables continual good performance to existing consumers and supply to new consumers. International Collaboration In ensuring a more secure, accessible and sustainable energy future, SP Group is an active member of several international and regional working groups which benchmark and share best practices on grid operations. Participants at the 2019 HAPUA Council meeting.

In Southeast Asia, SP Group represents Singapore in the Heads of ASEAN Power Utilities Authorities (HAPUA). HAPUA’s key objectives include strengthening regional energy security through interconnection development and enhancing the quality and reliability of the electricity supply system. SP Group is the Chair of the Working Group #3 to focus on the areas of Distribution, Power Reliability and Quality. 07 SP GROUP Sustainability Review FY2019/2020 SP Group continues to invest in infrastructure to uphold network reliability. Initiatives Energy Access – SDG 7.1 Investing in Network Infrastructure Upgrades Planning and investing in network infrastructure upgrades is key to ensuring consumers have reliable and safe access to electricity. As part of our accelerated gas mains renewal programme, we have replaced more than 70km of aging ductile iron pipelines with more durable polyethylene pipes. This significantly reduces the risk of gas leaks and improves gas safety. We have embarked on the upgrading of two key operational systems, for gas network monitoring and control, and to support all gas market activities in Singapore. The final connection of our transmission network in the north of Singapore was also completed, enhancing the security and reliability of supply serving Liquefied Natural Gas (LNG) customers in the area. Commissioned a new 400kV substation to support more industrial capacity We have a long-term asset renewal strategy – based on the performance, condition and age of our equipment – to ensure that our electricity network remains resilient. We commissioned a new 400kV substation to support more industrial capacity and renewed one of two 230kV interconnections between Singapore and Malaysia. We have also replaced 606 switchgear panels, 158 transformers and 253km of cables in the distribution network. In 2012, we commenced an underground transmission cable tunnel project to support SP Group’s long-term plan of securing reliable and efficient electricity supply for Singapore. The project will allow us to install, repair and replace aging assets, and upgrade our network efficiently, with minimal inconvenience to the public. We have since installed and commissioned seven transmission cable circuits in our cross-island underground cable tunnels that were completed in 2019. These circuits, spanning close to 138km, are part of our long-term plan to replace aging assets and meet Singapore’s future electricity needs. 08 SP GROUP Sustainability Review FY2019/2020 Smart Grid Index In 2018, we launched the world’s first Smart Grid Index (SGI) to help utilities measure and advance in key dimensions of grid development. The SGI received strong endorsement from industry experts and stakeholders. Covering seven key aspects of an electricity grid – 1) supply reliability; 2) monitoring and control; 3) data analytics; 4) integration of Distributed Energy Resources (DER); 5) green energy; 6) security, and 7) customer empowerment and satisfaction – the SGI allows utilities to understand their strengths and areas they can improve in. Today, the SGI measures and benchmarks grid smartness across 75 utilities from 35 countries. In 2019, utilities in Asia Pacific nations made significant improvements in the rankings with an overall improvement of 10 percentage points from 2018. Improvements were most notable in areas of integration of DER, security, and customer empowerment and satisfaction. For further details on the benchmarking scores, please refer to https://www.spgroup.com.sg/what-we-do/smart-grid-index. SECURITY & SATISFACTION CUSTOMER EMPOWERMENT Best Practices by Dimensions GREEN ENERGY MONITORING & CONTROL DER INTEGRATION DATA ANALYTICS SUPPLY RELIABILITY Performance Network reliability is an important contributor to the economy and SP Group aims to ensure minimum disruption to electricity and gas supply for all businesses and households. There are two key indicators that our industry measures when assessing performance on network reliability: i) SAIDI, a system index of average duration of interruption in the power supply indicated in minutes per customers, and ii) System Average Interruption Frequency Index (SAIFI), a system index of average frequency of interruptions in the power supply. In FY2019/2020, our SAIDI for the electricity network improved by over 35 per cent. FY2018/2019 FY2019/2020 Electricity SAIDI (min) 0.87 0.56 SAIFI 0.0307 0.0366 Gas SAIDI (min) 0.0932 0.2637 SAIFI 0.0014 0.0019 To ensure minimal service disruption to our gas network, we have been actively replacing aging ductile iron pipelines with more durable polyethylene pipes to improve our gas SAIFI and SAIDI performance. Future Outlook To meet the 30-30-30 targets and minimise customer supply interruption, we actively invest in infrastructure, technology and engineering capabilities to uphold high performance standards. We continually look for innovative and cost-effective ways to deliver faster and better services and empower our staff with the knowledge they need to increase productivity and bring value to our customers and stakeholders. 09 SP GROUP Sustainability Review FY2019/2020 Innovation Why This is Material Singapore has pledged to reduce its Emissions Intensity by 36 per cent from 2005 levels by 2030. It has recently committed to enhance its nationally determined contribution to the absolute peak emissions level of 65 million tonnes of CO 2 equivalent around 2030. By 2050, Singapore aims to halve the amount of emissions it produces from its 2030 peak, with the view to achieve net-zero emissions as soon as viable in the second half of the century. Innovation and new technologies are central to facilitating this transition. SP Group can be a key facilitator and enabler for this change. Our investments in climate-friendly innovations will not only power a greener tomorrow for our business, they benefit the entire ecosystem, including organisations and individuals trying to reduce their own footprint. Management Approach SP Group takes an active approach to keep at the forefront of new technologies. Our approach has been to tap the global innovation ecosystem for exposure, test new solutions and build new capabilities to enable us to deliver value-added solutions to customers. SP has been actively engaging the global innovation ecosystem through programmes such as the Free Electrons Global Accelerator. In partnership with nine other global utilities, SP Group invites promising energy-related start-ups to apply for the accelerator programme which runs annually. Into its fourth edition in 2020, Free Electrons received a total of more than 850 start-up applications from 86 countries. Since 2017, Free Electrons has received more than 2,300 applications and investments were made in more than 100 pilot programmes while more than S$30 million has been invested in start-ups. SP Group invests in venture capital funds globally to access the innovation ecosystems and keeps abreast of market and technology developments. Our venture capital funds provide SP Group with deal flow access to start-ups globally including Asia, US and Europe. Through this innovation ecosystem, SP Group has been identifying relevant and promising technologies to run pilots. This approach allows us to validate the technologies and performance in our local environment, and build new capabilities as we partner start-ups and organisations to develop new solutions. By 2050, Singapore aims to halve the amount of emissions it produces from its 2030 peak, with the view to achieve net-zero emissions as soon as viable in the second half of the century Since 2017, Free Electrons has received more than 2,300 applications from innovative energy startups. More than 100 pilot programmes were initiated between the utilities and start-ups. More than S$30 million has been invested in the start-ups. Free Electrons utilities and start-up participants in Berlin, Germany. 10 SP GROUP Sustainability Review FY2019/2020 Initiatives Energy Access – SDG 7.1 Electric Vehicle Charging The switch to low-carbon electric vehicles (EVs) is seen as an increasingly viable route for the decarbonisation of the transportation sector globally. With our geographic size, economic landscape and existing infrastructure, Singapore is well-placed to adopt green mobility, and SP Group aims to drive this change. Over the past two years, SP Group has been partnering organisations to set up EV charging stations across the island, in line with the government’s longerterm plan to build 28,000 electric vehicle charging points by 2030. In 2019, the high-speed EV charging network was increased to 200 points across Singapore, including 52 direct current fast chargers. Locating the charging points can be done via the SP Utilities app. Through the app, users can start and stop charging, and pay for the electricity used. This allows for greater convenience to users to access the largest fleet of EV charging points in Singapore. Renewable Energy – SDG 7.2 Solar Panels SP Group has installed solar photovoltaic (PV) panels at our headquarters and district offices and developed storage systems to harness and deploy energy efficiently. This experience enables us to work with partners in the community and industrial customers to achieve similar sustainable outcomes. The Integrated Energy Solutions system includes features like the SP Group’s direct current fast charging points offer our customers a convenient and quick way to charge their electric vehicles. “ We are very pleased to work with SP Group on the enabling infrastructure for EVs at Paya Lebar Quarter. We see EVs as representing a better environmental solution for cars in Singapore and are already seeing demand from our Paya Lebar Quarter office tenants for EV charging stations.” - Mr Richard Paine, Managing Director of Paya Lebar Quarter energy storage capabilities, energy sensors and a real-time digital platform to monitor, analyse and optimise energy usage. Machine learning models were also deployed to better monitor the panels’ condition to reduce the need for regular inspections. One such digital system was developed at the local SembCorp Marine Tuas Boulevard Yard that optimises energy consumption and harnesses solar energy for significant savings. The system is paired with 4.5 MegaWattpeak (MWp) solar panels, the largest single solar rooftop at a shipyard in Southeast Asia. It will provide up to 30 per cent of electricity consumed by the yard’s steel structure fabrication workshop during peak load. 11 SP GROUP Sustainability Review FY2019/2020 Green Hydrogen While renewable energy such as solar and wind has been at the forefront of clean energy solutions, alternative clean fuels such as hydrogen gas has the potential to offer consumers a viable option for accessing clean energy. With water and energy as the bi-products, hydrogen gas as a fuel offers plenty of potential, more so for Singapore, which has limited renewable options. In 2019, SP Group installed a hydrogen energy system at our training centre at Woodleigh Park in partnership with Marubeni Corporation and Tohoku University. The system generates green hydrogen through electrolysis powered by solar energy. This has helped us convert the training centre into the first zero-emission building in Southeast Asia that is powered by green hydrogen. Since October last year, the building, which consumes about 2,000 kilowatt hours of electricity a month – equivalent to the monthly usage of five four-room Housing Board flats – has been able to operate independently from the national grid. Waste to Energy Waste generation in Singapore has increased seven fold over the past 40 years, putting immense pressure on Singapore’s only landfill at Pulau Semakau which will be full by 2035. With land being a scarce resource, there is urgent need to explore alternatives for waste disposal. SP Group and Gardens by the Bay announced plans to pilot a zero-waste solution at the Gardens. This solution offers an effective alternative to incineration using compact gasification technology to convert waste into thermal energy and biochar. As a result, waste is reduced to only five per cent of its original volume and emissions are reduced by up to 20 per cent. The smart-waste management system could enable sustainable zero-waste districts to be viable in Singapore, bringing the country closer towards a circular economy. In addition to tackling the waste issue, this technology will also allow us to explore efficient alternative solutions to generating energy and reducing our reliance on fossil fuels. SP Group harnesses renewable energy to create clean energy solutions for customers. SP Group installed a hydrogen energy system at our training centre at Woodleigh Park in partnership with Marubeni Corporation and Tohoku University SP Group and Gardens by the Bay announced plans to pilot a zero-waste solution at the Gardens. As a result, waste is reduced to only five per cent of its original volume and emissions are reduced by up to 20 per cent. The smart-waste management system is deployed at Gardens by the Bay. 12 SP GROUP Sustainability Review FY2019/2020 Renewable Energy Certificates Platform In 2018, SP Group launched the world’s first blockchain-powered Renewable Energy Certificate (REC) marketplace. The marketplace enables the trading of RECs – for renewable energy producers to sell, and for consumers wishing to use green energy to purchase. In 2019, an agreement was signed with the International REC Standard Foundation for SP Group to be the first authorised local issuer of I-RECs in the Asia Pacific. This international accreditation means consumers can be assured of the integrity of each REC transaction. With the one-stop digital REC platform, SP Group is removing barriers so that big and small consumers can achieve their green targets seamlessly and securely. Energy Efficiency – SDG 7.3 Smart Building Solutions SP Group actively explores new technologies to support the energy needs of buildings and districts. With 75F, a building intelligence provider harnessing Internet of Things and machine learning, we are A sample of an REC that is issued to consumers. In 2018, SP Group launched the world’s first blockchain-powered Renewable Energy Certificate marketplace offering a micro-climate control solution that can save up to 30 per cent in energy consumption while improving occupant comfort. This solution has been deployed at DBS Asia Hub at Changi Business Park since February 2020. Tenancity was launched in 2019 to provide offices, malls and campuses with an energy-efficient solution in both tenant and common spaces. As part of this product, the consumption insights were also offered for the landlord and tenants to know about unusual deviations from benchmarks, anomalies in usage, and water leakage detection. This allows customers to take concrete steps to save energy and water. The first project was in Changi Airport where smart electricity and water meters were deployed for all tenants in Terminal 3. Data was aggregated through a wireless mesh network, becoming one of the first to integrate smart electricity and water meters in a wireless network within a building. Through the implementation of an energyefficient solution, coupled with advanced meters and operational analytics within the tenant premises, we are able to improve operational efficiency in Changi Airport Group’s utilities billing processes. Since then, similar projects have been undertaken at HDB Connection One and Nanyang Technological University. SP Group is also working with the newly set up Singapore Eco Office from the Ministry of the Environment and Water Resources and Temasek Holdings to transform Tampines into an Eco Town. This is part of the Singapore Government’s plans to rejuvenate and transform mature towns and make them more sustainable. SP Group’s micro-climate control solution allows customers to save up to 30 per cent in energy consumption while improving occupant comfort. 13 SP GROUP Sustainability Review FY2019/2020 District Cooling and Energy Saving Solutions At Marina Bay Sands, SP Group operates the world’s largest underground district cooling system. Here, chillers centrally produce chilled water during off-peak periods, store the chilled water using a thermal energy storage system, and supply the chilled water for air conditioning use at the buildings in the Marina Bay area. If renewable energy that is used to power the chillers suddenly fluctuates, the lithium ion battery will immediately discharge energy to balance the supply, hence overcoming the challenge of inconsistent renewable energy in a cost-effective way. For the innovative efforts, SP Group was presented with the 2019 Minister for National Development’s R&D Merit Award at the Urban Sustainability R&D Congress 2019. Performance SP Group’s low-carbon initiatives have enabled our customers to avoid more than 29,000 tonnesCO 2 in FY2019/2020, equivalent to planting more than 1.4 million rain trees 1 or taking more than 6,300 cars off the road for a year 2 . Measuring this progress against the target of helping our customers reduce their carbon footprint, these initiatives have achieved 19 per cent increase in the CO 2 avoided since 2018. Future Outlook SP Group recognises that Singapore lacks land to scale up renewable energy systems. However, we plan to work with our neighbouring countries on cross-border power supply. Building transmission lines to connect the countries and using renewable energy credits to facilitate power trading can allow Singapore to use clean power even if it cannot produce it. Furthermore, we will continue to work on our strategic areas for innovation to provide our customers with low-carbon solutions. SP Group’s low carbon initiatives have enabled customers to avoid more than 29,000 tonnesCO 2 in FY19/20, equivalent to planting more than 1.4 million rain trees or taking more than 6,300 cars off the road for a year SP Group operates the world’s largest underground district cooling system that supplies chilled water for air conditioning to buildings in the Marina Bay area. 1 One mature rain tree absorbs 0.0201 tonnesCO 2 a year - data from My Carbon Footprint study by South Pole 2 From US EPA Greenhouse Gas Equivalencies Calculator 14 SP GROUP Sustainability Review FY2019/2020 Customer Empowerment Why This is Material The transition towards a clean energy economy will largely be driven by end-user consumption. Given that SP Group provides electricity and gas transmission and distribution services to consumers in Singapore, customer education and empowerment will support Singapore’s target to transition to a low-carbon future. Beyond this, empowerment of customers can result in energy and cost savings for the customers of SP Group, increasing value to them. Management Approach SP Group’s customers are at the core of our business strategies. Our initiatives for the community and our customers are aligned with our mission – to deliver reliable and efficient utilities services to enhance the economy and the quality of life. Public education is an important aspect of our management approach. SP Heart Workers, the staff volunteers of SP Group, organise interactive workshops and training for members of the community on issues of energy efficiency and safety. In 2019, we engaged students from the Nanyang Polytechnic School of Interactive and Digital Media to develop a series of gas safety awareness videos. These videos were part of a gas safety campaign that we rolled out in September last year. Empowerment Through Technology To provide greater convenience to our customer base, we have embarked on a digital transformation journey. This has resulted in digital products that power internal business units and energy technology products that are available to customers. With energy technology as a tool to drive sustainability, the primary goals are to: 1) inform, 2) enable and 3) add value. Inform Timely data, information and recommendations on your energy use. Enable Take actions through direct control and automation with AI recommendations. Add Value Providing economic value while contributing to sustainability. 15 SP GROUP Sustainability Review FY2019/2020 Initiatives Energy Access – SDG 7.1 Open Electricity Market In 2018, the electricity market in Singapore opened up, allowing residential consumers to choose their utilities package from new retailers in the market. Regardless of their choice of whether to remain with SP Group at the regulated tariff, or switch to another electricity retailer, SP Group is committed to helping consumers make the right decisions which enable them to save energy and cost. Typical savings are between 20 per cent to 30 per cent off the regulated tariff. To demonstrate our commitment, we have rolled out a price comparison feature on the SP Utilities app, whereby customers can see various price plans at a glance. This makes it easier for consumers to select price plans that best suit their consumption needs. Energy Efficiency – SDG 7.3 SP Group has facilitated the switch for many of our customers to enable them to save 20 per cent to 30 per cent off the regulated tariff Smart Technology SP Group is increasingly shifting its focus to use data science and artificial intelligence (AI) to deliver efficient energy solutions to our customers. We refer to this as an “Energy Brain”. This “Energy Brain” uses intelligence gathered from a large volume of consumption data from both residential homes and businesses to provide customers with data-driven solutions. Beyond this, we are increasing customer empowerment by installing advanced electricity meters for all households, allowing residents to access their half-hourly electricity usage through our SP Utilities app. These advanced meters allow residents to gain a better picture of their consumption patterns, enabling them to implement reduction and efficiency measures in a meaningful manner. SP Group uses data science and artificial intelligence to deliver efficient energy solutions to customers. 16 SP GROUP Sustainability Review FY2019/2020 Energy Efficiency – SDG 7.3 Environmental Awareness In March 2020, SP Group launched the enhanced Carbon Footprint calculator, called My Carbon Footprint. It enables everyone in Singapore to be more aware of the environmental impact of their daily actions. First launched in December 2019, the initial version allows users to view the carbon emissions resulting from their electricity consumption. The calculator that is available on the SP Utilities app allows everyone in Singapore to measure their environmental impact from their daily lifestyle choices according to their household profile, mode and duration of commute, frequency of holiday travel, spending habits and food consumption. Approximately 13 per cent of SP Utilities app users had participated in GreenUP and completed over 1.3 million activities In addition, SP Group has launched initiatives that allow A screengrab of My Carbon Footprint. consumers to adopt a more sustainable lifestyle through their daily actions. GreenUP, also available on the SP Utilities app, aims to educate and empower customers to go green in a fun and interactive way. As of 31 March 2020, approximately 13 per cent of SP Utilities app users have participated in GreenUP and completed over 1.3 million activities cumulatively since its launch in September 2019. The Energy Savings Challenge was rolled out through various platforms including the SP Utilities app. A partnership between the National Environment Agency and SP Group, the Challenge was first launched in 2017 as a call to households to reduce their electricity use by 1 per cent by practising simple energy saving habits as a way of life to contribute to a sustainable environment. With the GreenUP feature on the SP Utilities app, users can participate in challenges and earn rewards. 17 SP GROUP Sustainability Review FY2019/2020 Performance Customer Empowerment As of 31 March 2020, 46 per cent of households and 43 per cent of eligible businesses have switched to buying electricity from a retailer of their choice. They have since enjoyed savings of about 20 per cent to 30 per cent off the regulated tariff. Customers also have the option of buying electricity from the wholesale electricity market. Under this arrangement, customers buy at the wholesale electricity price which varies every half an hour depending on the prevailing demand and supply situation in Singapore’s wholesale electricity market. SP Group has installed 480,000 smart meters to businesses and households as of March 2020 Customers are empowered with their utilities consumption data via the SP Utilities app. With more than 900,000 app downloads, customers are submitting their meter readings, viewing their bills and paying directly via the SP Utilities app. Customers can pay with all credit cards from over 380 banks and enjoy rebates and rewards offered by banking partners for payment through the app. We have processed over 800,000 unique transactions through the app since 2019, giving customers greater convenience. SP Group has also installed 480,000 smart meters to businesses and households as of March 2020 and will continue to roll these out incrementally over the next five years. Future Outlook SP Group’s overarching goal is to empower everyone with the knowledge and tools to foster a low-carbon future for all. We will continue to harness digital technology to provide our customers with the information and means to lower their electricity consumption and adopt a more sustainable lifestyle. SP Group enables a low-carbon and sustainable future for Singapore. 18 Sustainability Review FY2019/2020 2 Kallang Sector Singapore 349277 T. +65 6916 8888 F. +65 6304 8188 https://www.spgroup.com.sg/

Media Release New learning centre opens in Toa Payoh to empower children who learn differently SP Group donates S$300,000 to support students from lower-income families with undiagnosed learning challenges, advancing DAS’ “Going Beyond Dyslexia” initiative SINGAPORE, 22 FEBRUARY 2025 — The Dyslexia Association of Singapore (DAS) officially opened its second largest learning centre at Toa Payoh today, expanding support for students who learn differently. This brings the total number of centres providing interventional services across Singapore to 12, reflecting DAS’ growing commitment to empowering struggling learners, including those without formal diagnosis, to achieve their true potential. Mr Chee Hong Tat, Minister for Transport, Second Minister for Finance and Adviser to Bishan-Toa Payoh Grassroots Organisations, graced the event as the guest-of-honour. The DAS Bursary Fund also received a S$300,000 boost from SP Group, extending vital support to learners from lower-income families, who do not have a formal diagnosis of special educational needs such as dyslexia but are impacted similarly by learning differences, to access intervention services. Since April 2024, DAS has taken the transformative step towards inclusive education by opening up its services to enroll students without formal diagnosis of a learning difference, with many coming from lower-income families and requiring financial assistance. This effort to extend support beyond formal diagnosis exemplifies the “Going Beyond” culture at DAS to constantly strive to make a greater impact on the lives of individuals with dyslexia. While dyslexia affects approximately 4 to 10 per cent of any population, the proportion of struggling learners as a whole is significantly higher, at about 20 per cent. Of every 10 students assessed for dyslexia at DAS, three do not receive a dyslexia diagnosis, yet half of them would benefit from targeted intervention and resources to bridge their learning gaps. One such student is eight-year-old Nur Evren Elveera, a Primary 2 student at Zheng Hua Primary School, who faced early challenges in writing and pronunciation. Concerned with her learning difficulties, her parents sought an assessment at DAS, where it was confirmed that while she does not have dyslexia, she would benefit from structured literacy support. Through proactive intervention, including DAS’ IReaCH Programme and additional tutoring, Evren has developed strategies to improve her reading and spelling. Her journey highlights the importance of accessible learning support for all children who face learning challenges, regardless of formal diagnosis. “The new Toa Payoh Learning Centre represents another step forward in our commitment to building an inclusive society where every learner can thrive, regardless of their family’s financial circumstances. Embracing our “Go Beyond” spirit, we are broadening our support for more children navigating learning challenges. We are extremely grateful to SP Group and all our donors for their unwavering support in advancing our cause,” said Mr Lee Siang, CEO of DAS. Mr Stanley Huang, Group CEO of SP Group, said, “As we work towards uplifting lives and fostering an inclusive community, we recognise that early and targeted intervention is instrumental in establishing a strong foundation for young learners with special education needs. SP Group is committed to empowering their sustained and holistic development, so that they can gain skills and opportunities to thrive. Our partnership with DAS aims to level the playing field for children and youth who learn differently, providing them hope and confidence to realise their potential.” Located at Block 240 Toa Payoh Lorong 1 and just a short walk from Braddell MRT Station, the DAS Toa Payoh Learning Centre aims to better serve students residing in central, central-east and north-east Singapore. Spanning close to 330 sqm with 11 classrooms, the centre will help to ease capacity constraints at existing DAS centres. Besides adjoining classrooms that can be used for large meetings, other facilities include a staff pantry with self-service facilities, virtual assistants and a library. Offering the Main Literacy Programme, along with Chinese, Preschool, PREP 2 PSLE, Science, Specialist Teaching and Maths programmes, the DAS Toa Payoh Learning Centre is supported by a team of highly-skilled Educational Therapists, Speech and Language Therapists and Specialist Psychologists. The DAS Main Literacy Programme (MLP) is part-funded by the Ministry of Education (MOE). Apart from SP Group, other key donors for the various DAS programmes not funded by MOE with contributions of above S$100,000 in the financial year 2024-2025, include Singapore Teochew Foundation, Lim Hoon Foundation, UOB, Ishk Tolaram Foundation and World Vision. DAS also received an in-kind contribution of LED lighting from Signify for the new Toa Payoh Learning Centre .

Media Release SP Develops Future Energy Leaders Through First Energy Managers Programme And Industry Scholarships Singapore, 2 November 2018 – Singapore Institute of Power and Gas (SIPG), as the centralised training institute for the power and gas sectors, announced today the successful completion of its first Energy Managers Programme (EMP). The pioneer cohort of 19 energy sector professionals was recognised in a ceremony during Singapore International Energy Week 2018, witnessed by Dr Tan Wu Meng, Senior Parliamentary Secretary, Ministry of Trade and Industry and Ministry of Foreign Affairs. The programme, which is under the SkillsFuture Leadership Development Initiative, is designed to build a pipeline of strong leaders for the energy sector as they address issues and opportunities in today’s transforming and disruptive landscape. Building on its inaugural run, SIPG is opening its programme to participants from ASEAN utilities and other international companies in the energy value chain, curating a broader range of experiences, perspectives and real-world applications. Mr Peter Leong, Principal of SIPG, said, “We customised this programme to help energy industry managers hone their well-rounded leadership skills through blended learning in the classroom and field trips to companies in Singapore and overseas. They have personally benefitted from networking with peers from across the value chain. They have also gleaned insights on driving advancement and innovation amidst the rapid industry disruption, in order to serve all consumers better.” Spanning five months from February this year, the programme’s first participants were emerging leaders from generation companies and SP Group. Through workshops, dialogues with senior leaders from the energy sector and government, as well as a learning trip to China, the participants were exposed to pertinent challenges the industry faces, in Singapore and around the region. They also gained valuable insights from individual coaching sessions and working on action projects. Mr Neo Bing Hui, Senior Operations Engineer, YTL PowerSeraya Ltd, said, “The Energy Managers Programme (EMP) has helped broaden my views of the industry in general, providing a different perspective of how challenges can be viewed in the energy sector. After going through EMP, I have gleaned more insights on my leadership style and how I can effectively improve communication with my team mates. I am excited to start applying what I've learnt from this programme.” The pressing need to inspire the energy sector to groom the next generation of energy leaders is why the Energy Market Authority is supporting the programme. Its Chief Executive, Mr Ngiam Shih Chun, said: “For the energy sector to embrace new opportunities and challenges, there is a need to engage and develop tomorrow's energy leaders. They will need to be agile and adopt a growth mindset to lead their organisations forward. EMA supports SIPG in playing a crucial role in providing a programme to grow our future energy leaders.” Nurturing engineering talent In developing future engineering talent, SP Group also awarded two Energy-Industry Scholarships to students from institutions of higher learning – Ms Choo Wei Ming, 19, from Ngee Ann Polytechnic and Mr Muhammad Syahiran bin Jamal, 20, from Singapore Polytechnic. SP Group’s Chief Human Resource Officer, Mr Ng Seng Huwi, presented the scholarships to Wei Ming and Muhammad Syahiran, at a ceremony during the Youth@SIEW event earlier today. The scholarship serves to nurture talent for the energy sector and support students with a passion for engineering in achieving academic and career aspirations. They will join SP Group when they complete their studies. About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

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.

General Information 1 1.1 Introduction General Information 1.1.1 SP Services Ltd (SPSL), SP PowerAssets Ltd (SPPA) and SP PowerGrid Ltd (SPPG) are subsidiaries of Singapore Power Ltd. SPSL provides support services for the electricity market. It receives requests for electricity service connection; offers terms and conditions of service connection; arranges for service connection energisation/turnon; and collects transmission charges, security deposits and charges for other services on behalf of SPPA. SPSL also bills customers for consumption. SPPA is the Transmission Licensee and owner of the transmission and distribution network. SPPG, the managing agent for and on behalf of SPPA, develops, operates and maintains the transmission and distribution facilities. 1.1.2 The supply of electricity and electrical installation practices are governed by the Electricity Act and its subsidiary legislation. 1.1.3 “Customer” and “consumer” shall have the same meaning in this handbook. 1.2 Connection Voltages and Supply Frequency 1.2.1 In Singapore, customers’ installations are connected at the following voltages: (a) Transmission voltage of 66kV and 230kV (b) Distribution voltage of 230V, 400V, 6.6kV and 22kV (may vary within ± 6%) 1.2.2 The supply voltages are classified in the following categories: (a) Low Tension (LT) refers to 230V, single-phase and 400V, 3-phase (b) High Tension (HT) refers to 22kV and 6.6kV (c) Extra-High Tension (EHT) refers to 66kV (d) Ultra-High Tension (UHT) refers to 230kV 1 1.2.3 The following connection schemes are provided, according to customers’ load requirements. It shall apply to new and existing customers, including customers who are revising their Contracted Capacity. The power factor shall be based on 0.85. (a) Low Voltage, 50 Hz: • 230V, single-phase, up to a maximum of 23kVA, 100A • 400V, 3-phase, 4-wire system, up to a maximum of 5000kVA per substation (b) 22kV, 50 Hz, 3-phase, 3-wire system for a Contracted Capacity: • between 1,700kW and 12,750kW for 2 HT 22kV services • between 12,751kW and 25,500kW for 4 HT 22kV services (c) 66kV, 50 Hz, 3-phase, 3-wire system for a Contracted Capacity: • between 25,501kW and 84,999kW for service connection from the nearest feasible 66kV substation • between 85,000kW and 169,999kW for service connection from the nearest feasible 66kV source station (d) 230kV, 50Hz, 3-phase, 3-wire system for connection with minimum Contracted Capacity of 85,000kW 1.2.4 Where the customer requires a connection voltage and/or frequencies that differ from those specified above, the customer is required to provide, install and maintain the necessary transformation equipment. 1.3 Submission of Application 1.3.1 SPSL serves as a one-stop customer service centre. It receives all application forms on behalf of SPPA, and responds to all applications made by the Licensed Electrical Worker (LEW), who acts as the customer’s agent for connection to the transmission system. SPSL may, in its sole and absolute discretion, deal with the customer directly. 1.3.2 Customers applying for their installations to be connected to SPPA’s transmission system must submit their applications through their LEWs. Every application must be accompanied by all supporting documentation requested by SPSL, including a letter of consent as shown in Appendix 1. The applications must be submitted via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. A user manual can also be downloaded from the website. 1.3.3 For data centre developments, customers will need to include IMDA acknowledgement email as part of application submission. Please refer to Singapore Power (SP) eBusiness Portal for more information. 1.3.4 For developments in the conception or planning stage for a new connection or an upgrade / increase in Contracted Capacity to an existing connection, the customer is advised to seek consultation regarding SPPA’s requirements. This includes considerations such as the provision of a substation, modifications to an existing 2 substation/connection, and lead time required for service connection, which is subject to network availability and includes any network reinforcement that may be necessary to support the intended load connection. The Consultation Form must be submitted by the customer’s LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. A user manual can also be downloaded from the website. 1.4 Provision of a Substation 1.4.1 Direct service connection from SPPA's LT network to the customer’s installation is available for a small load requirement not exceeding 280kVA (400A). However, the provision of a direct service connection is dependent on the available network capacity in the vicinity. If there is insufficient capacity, the customer is required to provide a substation for the connection. 1.4.2 For a larger load requirement exceeding 280kVA (400A), the customer has to provide a substation for SPPA to install necessary equipment to cater for the load. 1.5 Domestic Premises and Load Requirement not exceeding 45kVA 1.5.1 For premises where the electricity meter has already been installed by SPPA and no extension or rewiring work is required, customer may submit for an opening of utilities account to SPSL directly. Turn on of electricity service connection will happen on customer’s requested turn on date, subject to availability of appointment slots. 1.5.2 For premises where there is no electricity meter or where extension or rewiring work is required, the customer has to engage a LEW and submit an application for load connection. 1.6 Meter 1.6.1 All meters required for measuring a customer’s electricity consumption and demand (where applicable) are provided and maintained by SPPA. The customer has to provide meter boards, compartments, kiosks, etc. as SPPA requires them for the installation of its metering equipment. 1.6.2 Master- And Sub-Metering (a) A “Master-meter” is a meter measuring the consumption for all units and common areas in a building or cluster of buildings, which are used or occupied by multiple consumers. For master-metering scheme, the common services load must be at least 10% of the total load for the premise. (b) A “Sub-meter” is a meter measuring the consumption for a unit in a building or cluster of buildings used or occupied by multiple consumers, whose electricity is taken through a Master-meter. (c) A master and sub-metering scheme is applicable for multi-tenanted premises. Under this scheme, the electricity supply is metered at the intake point and each tenant’s supply is also separately metered and billed under the appropriate tariff. The owner/ developer/ landlord shall be billed for the difference in the consumption between the consumption metered at the intake point and the 3 summated consumption of the tenants. Where the owner/ developer/ landlord takes supply at high tension and is responsible for stepping down the supply to 230V/ 400V for distribution to tenants, a rebate of 2.5 % on the summated consumption of the tenants will be granted.

Securing of network capacity is achieved by confirmation of Contracted Capacity in Customer Connection Agreement or approval of Revision of Contracted Capacity by the Transmission Licensee. 7 2.3.2 For data centre developments, customers will need to include IMDA acknowledgement email as part of application submission. Please refer to Singapore Power (SP) eBusiness Portal for more information. 2.4 Processing of Application 2.4.1 Generally, SPSL responds to applications within 10 business days. 2.4.2 The responses are made according to the following customer categories: (a) Contestable Customer • A Consumer Connection Agreement, containing the service connection charge payable, the offer letter and the standard terms and conditions with respect to the distribution service connection. • If a substation is required, a letter stipulating the requirements will be forwarded to the customer. It will be followed by an Agreement subsequently after the substation plans are endorsed. (b) Non-Contestable Customer • A Quotation, containing service connection charge payable and the conditions of service with respect to the distribution service connection. • If a substation is required, a letter stipulating the requirements will be forwarded to the customer. A Supply Agreement including the service connection charge payable and the terms & conditions with respect to the distribution service connection, is offered after the substation plans are endorsed. 2.5 Commencement of Work 2.5.1 SPPG commences work only when the Agreement has been signed and received by SPSL, together with payment of service connection charges. 2.6 Type of Premises 2.6.1 Multi-Metered Premises (a) Multi-metered premises are premises where the landlord/ MCST (i.e. a mastermetered consumer or directly connected consumer) receives bulk intake service connection from SPPA, and transforms/ reticulates the supply to all the tenants (i.e. sub-metered consumers) within the premises. Any application for new or modified connection (includes upgrading) for the bulk intake to the multi-metered premises must be made by the landlord through its LEW. (b) A master-metered consumer means a consumer that is responsible for the common usage of a master-metered installation, which is connected to the transmission system. 8 (c) A master-metered installation means an installation in which supply is received by a master-metered consumer and sub-metered consumers (d) A master-metered installation shall have an independent address and its own dedicated access. (e) A sub-metered consumer means a consumer, other than a master-metered consumer, that receives supply in a master-metered installation via the electrical system owned by a master-metered consumer. 2.6.2 The landlord/ MCST or HDB, in the case of HDB premises, must ensure that the total applied load requirement for service connections to the multi-metered premises meet the total existing and future load requirements for all tenants. All tenants applying for any upgrading of load must do so through their master-metered consumer. In this regard, the master-metered consumer must approve the load of all tenants within the premises. 2.6.3 If the landlord’s existing approved load is insufficient to cater for the tenants’ load requirement, the landlord, as a master-metered consumer, must submit an application to SPSL for modification (upgrading) of service connection to the existing premises. In this case, the existing service cables are amalgamated with the new intake. Hence, there will not be separate direct connections to the tenants of such premises. 2.7 Premises in Private Housing, Industrial Estates, Commercial Developments Requiring Provision of Low Tension (LT) Distribution Network 2.7.1 For connection to premises where several parcels of land are to be sold or leased individually, one or more substations must be provided by the developer. Where the individual parcels of land are to be sold prior to development of these substations, details of the substation requirements and approved load must be included in the sales agreement by the future land parcel’s owner or lessee. 2.7.2 The developer must provide the development’s total load requirement and include the breakdown of the individual premises’ load requirement (as specified in the sales agreement) and the communal load requirement, if applicable. 2.7.3 In the case of landed housing estate development, the LEW must liaise with relevant Authorities, applicant’s appointed Architects/Civil & Structural Qualified Person and owner of the house for the siting of proposed overground distribution boxes on turfed areas. SPPA will provide and install the LT distribution network and service connection cables for the development. 2.7.4 Premises Involving Temporary Connection with Provision of Substation: (a) Special terms and conditions apply in such cases for temporary connection to construction worksites and other temporary premises. The term granted for temporary connection is usually 24 months. (b) Where there is a need for the provision of a temporary substation, the customer must provide the site and construct the structure of the substation according to the requirements of SPPA. 9 (c) There will be a need to install the necessary cables and equipment to facilitate the temporary connection to the distribution network. The customer pays outright costs for the cables and a monthly hiring charge for the use of the equipment during the term for temporary connection. 2.7.5 Developers are advised to connect residential developments to the LT distribution network. Opting for a HT supply intake setup will subject the landlord/MCST to the following: (a) Monthly Contracted Capacity charges (b) Operating costs associated with HT equipment setup 2.8 Provision of Substation 2.8.1 When an application for load connection necessitates the provision of a substation (Appendices 9 and 10), a site must be provided and a substation constructed by the customer at its own cost. 2.8.2 The customer can either choose his substation to be a dedicated or non-dedicated one (Appendix 35). If the customer opts for a dedicated substation, he has to inform SPPG when he applies for connection. Otherwise, it shall be assumed that the substation would be non-dedicated. 2.8.3 The substation is to be sited at an inconspicuous location, away from the main entrance of the development and major public roads. It is recommended to harmonise, blend and integrate the substation with the overall design of its development. The siting of the substation must ensure continuous and unobstructed vehicular access to the substation and the associated lead-in pipes at all times, to facilitate equipment delivery, operational activities, maintenance and cabling works by SPPG. 2.8.4 SPPG’s officers and vehicles will have full and unrestricted access to the substation at all times (Appendix 15). 2.9 Service Connection Cables 2.9.1 Generally, SPPA supply, install and maintain customer service cable. However, if the customer’s switchroom is not abutting to SPPA’s switchroom or at different level to the substation building, or service cable to be installed in cable tray/ ladder, or the cable termination to the customer switchboard is not via bottom entry, the customer shall supply, install and maintain the service cable. In the event that customer supplies the service cable, the customer’s LEW shall ensure that the service cable complied with SPPA cable specification, and submit cable sample and specification to Distribution Engineering Section for approval prior to procurement. The general type of cables for service connection is shown in Appendix 36. 2.9.2 For service cable that is supplied, installed and maintained by SPPA, customer shall provide UPVC lead-in pipes from intake point to 300mm beyond boundary line or the roadside drain abutting public road at a depth not exceeding 2.0m from the finished road level.

This practice is encouraged as incorporating SPPA’s requirements in a developer’s preliminary proposal would expedite the application process at a later stage. 2.11.2 To initiate the connection consultation process, the customer has to submit the online Consultation Form through an LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. 2.12 Application for Transmission Connection 2.12.1 The following are steps in the application for service connection: (a) The customer submits the online Application Form 2 through an LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg, together with a letter of consent (Appendix 1) and IMDA acknowledgement email (for data centre applications only). (b) A connection proposal, duly endorsed by the PSO, is given to the customer. It outlines the connection scheme, connection voltage, connection equipment and facilities required of the customer and the estimated connection charges. 2 The 5-year load projection provided by the Customer in the CS1 application form is for planning purpose. Securing of network capacity is achieved by confirmation of Contracted Capacity in Customer Connection Agreement or approval of Revision of Contracted Capacity by the Transmission Licensee. 11 SPPG endeavours to respond to the customer within 60 business days and 100 business days for 66kV connections and 230kV connections respectively. 2.12.2 Where the application requires the provision of an EHT substation, the customer must adhere to the general requirements (Appendix 16). 2.12.3 Once customer acknowledges acceptance of SPPG’s connection proposal, SPPG proceeds to execute the Consumer Connection Agreement through SPSL. The Agreement contains an Offer Letter, the standard terms and conditions associated with the connection and an estimation of the connection charges. 2.13 Lead-Time for Application of Transmission Connection 2.13.1 The timely provision of electricity supply to a development involves the joint efforts of SPSL, SPPG, and the customer and their agents, such as the LEW. While SPSL and SPPG will make every effort to engineer and implement the connection scheme, it is at the same time essential for the new customers and their agents to co-operate via timely submission of applications and plans, timely acceptance of the terms and conditions of connection and compliance with the necessary SPPA or Transmission Code requirements. It is the responsibility of the customers to manage and direct their agents to ensure that their agents comply with the necessary SPPA or Transmission Code requirements. 2.13.2 As a guide for the customer and their agents, the typical lead-times for the events leading to the energisation of 66kV service connections, for a service cable length of approximately 2km, are listed in the box below. The actual lead time for energisation may vary for each connection, depending on the actual service cable length and the progress of intermediate events leading to completion of service connection works. Customers will be informed accordingly either at the point of application or at any time a review is required. For 230kV service connections, the customer will be informed of the lead-time only at the point of application. 2.13.3 Estimated Lead Time for Energisation of 66kV Service Connection Events New 66kV connection from SPPA’s nearest existing substation From day of execution of consumer connection agreement to energisation of service connection 26 Months 1 Notes: 1 Lead time is based on a service cable length of approximately 2km and is subject to change based on length of service connection cables. Note that this lead time excludes the Major Infrastructure consultation and approval process. In respect of Paragraph 1.2.3 where a new or existing customer needs to be connected to a source substation, the customer needs to consult SPPG at least 3-5 years in advance to cater for advanced planning and longer service connection cables where required. 12 2.14 Technical Requirements of Distributed Generation and New Extra / Ultra High Tension Connection 2.14.1 The details of technical requirements at the electricity supply network Point of Common Coupling (PCC) for Distributed Generation (DG) and New Extra / Ultra High Tension (EHT/UHT) connection are highlighted in Appendix 46. 2.14.2 The Consumer shall ensure that multiple sources of transmission, and/or distribution, systems are not connected in parallel at any time, and that any switching between circuits is undertaken on “black changeover” or “break before make” basis. 2.14.3 Some of the requirements are covered in the Transmission Code issued by Energy Market Authority (EMA).
