Media Release New Residential Demand Response Pilot to Empower Households to Reduce Electricity Consumption during Demand Peaks The Energy Market Authority (EMA) and SP Group (SP) will pilot a Residential Demand Response (R-DR) programme to empower households equipped with smart meters to actively reduce electricity consumption during demand peaks in the power system. Targeted to be launched by second half of 2024, this pilot is the first-of-its-kind in Singapore to call upon households to make a significant difference for a more resilient and sustainable energy future. With system peak demand forecasted to increase at a compound annual growth rate of up to 6.5% over the next five years, reducing electricity consumption temporarily during peak demand periods, otherwise known as Demand Response (DR), helps to keep the power system running smoothly and more efficiently by making use of demand-side resources in addition to supply-side (such as large conventional power plants) to balance electricity demand and supply.  For commercial and industrial companies, EMA has seen about a 1.5 times increase in demand-side resources, totaling to about 100MW since the launch of EMA’s regulatory sandbox[1]. With smart meters progressively being deployed to residential and non-residential consumers, more consumers will soon be able to contribute to DR, by using these smart meters to monitor their electricity consumption, making electricity management simpler and more rewarding. Consumers can keep track of their weekly carbon emissions and adjust their electricity consumption habits accordingly to help reduce emissions, thereby minimising their environmental impact. As of September 2023, SP has installed more than 834,000 smart electricity meters across residential and non-residential premises. The residential demand response pilot will use the SP mobile application (SP app) to send alerts to participating households to temporarily reduce or defer their electricity consumption. Households can take action by deferring the use of home appliances such as washing machines or dishwashers, or lower the temperature or even switch off air-conditioning. Participants will in turn enjoy benefits such as financial incentives. On the pilot for households, Mr Ngiam Shih Chun, Chief Executive of EMA, said: “The demand response pilot helps to involve households in lowering electricity demand during peak periods. This can help create a more sustainable and efficient energy ecosystem for everyone.” Mr Stanley Huang, Group Chief Executive Officer of SP Group, said: “Partnering EMA on this pilot, SP Group will empower consumers with digital solutions to be more energy efficient and reduce carbon emission. Enhanced features on our SP App will provide consumers with timely and useful information on their utilities usage and patterns. Insights from this data are aimed at nudging consumers to make adjustments easily to reduce their consumption." [1] In 2022, EMA launched a two-year regulatory sandbox for commercial and industrial companies to optimise their energy consumption. Participating companies will have to manage their electricity demand when activated and receive payments as an incentive for reducing their electrical demand on the national power grid. -- End -- About the Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

Media Release SP Group donates $850,000 for preventive outreach to isolated youths, run by Youth Guidance Outreach Services Cyber Outreach initiative aims to prevent them from becoming “hidden youth”. SINGAPORE, 5 DECEMBER 2025 – SP Group (SP) is donating S$850,000 to Youth Guidance Outreach Services (YGOS), to support its Cyber Outreach initiative, providing rehabilitation and prevention programmes for youths who may be addicted to online gaming and face the risk of social isolation. Through early intervention, the initiative aims to prevent them from becoming “hidden youth” – individuals who are disconnected from school, family, and the community and isolate themselves at home. This builds on SP Group’s past contributions to YGOS’ outreach programmes, bringing its total contributions to S$1.6 million. The initiative was launched today by Mr Xie Yao Quan, Advisor for Jurong Central GROs. Mr Xie witnessed the presentation of SP’s donation to YGOS, which was made through Community Chest. Extensive social isolation among youths can lead to poor physical health, strained family relationships, increased risks of psychological issues and even suicidal behaviours[1]. According to the Ministry of Manpower’s 2024 Labour Force Survey[2], around 17,000 youth, aged 15 to 24, in Singapore were not in school, employed nor undergoing any form of training in 2023. This represents 4.1 per cent of youth in Singapore who may be at risk of becoming “hidden youth”. This year, the government reaffirmed its commitment to preserve social mobility and strengthen safety nets – building a nation that prioritises youths and future generations. In his first parliamentary address as Prime Minister, Lawrence Wong[3] cited growing concerns among young people on intensified competition and social stratification, highlighting similar global trends such as "躺平 (tang ping)" in China, "hikikomori" in Japan and "quiet quitting" in the West. He emphasised Singapore’s commitment to defy these trends. Mr Xie said, “The world our youth face today is changing faster than ever – shaped by technology, global challenges, and evolving social norms. As a community, we must respond with understanding and action by creating safe spaces, strengthening family bonds, and offering various pathways for learning and growth. Together, we can help young Singaporeans feel valued and supported in building their future.” Mr Stanley Huang, Group CEO of SP Group, added, "Our youth today are the foundation and future talent pipeline for our nation’s growth and development. We are committed to empowering them with the right support and resources to thrive in an increasingly complex digital world. By effectively engaging them where they are, we can connect with them in ways that resonate with their interests, and foster a sense of self-worth and belonging. This in turn can help build their confidence, hone their social skills and prepare them for a smooth transition into young adulthood.” “We believe that early intervention is critical in supporting youths before challenges escalate. With the launch of our Cyber Outreach, a dedicated team to run the programme, and through our ongoing initiatives, we aim to extend sphere of connections and mentoring efforts. These will help us go further in creating a stronger and more supportive ecosystem – where every youth feels safe, seen, and empowered to do their best”, said Wilson Tan, Executive Director of YGOS. One of the youths who has benefitted from the intervention programme is 14-year-old Joey Chung. Joey was constantly immersed in online activities as she felt unseen and unheard. Before joining YGOS, she often hid behind the screen – a common behaviour among hidden youths who turn to gaming or online spaces to feel safe. At YGOS, Joey found something different: a genuine connection with a community that values her for who she is, beyond just a username. “I usually play Roblox with my online friends through a masked identity,” she said. “But here, I feel supported and can be myself. The mentors here actually care, listen and encourage me to express my doubts and concerns, and share about things that bring me joy.” A highlight of the event today was a gaming tournament attended by youths between the ages of 13 and 24 years old and community partners. About 120 participants, including a team from SP’s gaming interest group, competed in Mobile Legends: Bang Bang, a multiplayer online battle arena mobile game. By bringing the youths together to interact in person on a common interest in a safe, environment, the event aims to foster genuine connections and build a sense of community. Beyond the tournament, the youths explored educational and interactive booths hosted by YGOS, REACH Community Services and Fei Yue Community Services. These booths offered various outreach services such as how YGOS’ Cyber Outreach team connects with hidden youths online to draw them out of isolation. In 2023, SP contributed $750,000 to YGOS to launch the first-of-its-kind mobile youth engagement outpost with an electric vehicle, and to enable the full refurbishment of its youth centres in Woodlands and Ang Mo Kio to expand service delivery and outreach programmes.

Media Release Singapore’s First Centralised Power Plant Simulator & Structured Genco Training Programme 1. Workforce training on operations for Singapore’s power generation companies (Gencos) will now be centralised and standardised with the launch of Singapore’s first Centralised Power Plant Simulator (CPPS). 2. Developed by the Singapore Institute of Power and Gas (SIPG) – the Centralised Training Institute for Power and Gas sectors – in partnership with the Energy Market Authority (EMA) and Gencos, the CPPS courses mark the first time that Gencos operating in a competitive environment have come together to collectively design and level training standards for the sector. This ensures a consistent level of training, which plays a critical role in ensuring a secure and stable supply of electricity for Singapore. 3. Six courses integrated with CPPS training have been co-developed by SIPG and Gencos comprising Keppel Merlimau Cogen O&M, PacificLight Power, Sembcorp Cogen, Senoko Energy, Tuas Power and YTL PowerSeraya. Spanning basic to advanced levels, the training programme establishes a consistent standard for skills training, such as in power plant operations, process controls, and management of common equipment alarms and malfunctions in a controlled environment separate from actual day-to-day plant operations, ensuring the safety of participants as well as plant and system reliability. 4. A simulated environment also ensures that the workforce could be trained in scenarios which are rare in the power sector but can lead to plant shutdowns. A unique feature of the CPPS courses is that various Gencos have committed to provide trainers who are industry practitioners, who will be able to impart valuable knowledge and skills to the participants. 5. As part of the launch of the CPPS, SIPG has introduced a structured training programme consisting of two new Power Generation Certificate Programmes with certificates recognised by all Gencos. Certificates will be issued upon the completion of the CPPS courses, as well as other Power Generation courses offered by SIPG. 6. Minister of State (MOS) for Trade and Industry Low Yen Ling officiated the launch of the CPPS at SIPG today. In her opening speech, MOS Low commended key industry partners for the strong collaboration to bolster the competency of its workforce. 7. Mr Chia Soo Ping, Principal of SIPG, said: “As the energy landscape continues its dynamic and transformative journey, SIPG is focused on cultivating competencies and technological know-how needed for the industry to keep pace with change. The Gencos’ collaborative and structured approach promotes sharing and adoption of best practices. The Centralised Power Plant Simulator training reaps efficiencies and optimises the pooling of resources and expertise across all Gencos in Singapore to strengthen the overall resilience of the workforce for the energy sector.” 8. On the launch of the CPPS, Ms Violet Chen, EMA’s Industry Ecosystem Development Director, said: “We are heartened by the collective effort of SIPG and Gencos to strengthen the training of its workforce. The Power sector will continue to play a critical role in keeping the lights on and gas flowing for Singapore as we step up efforts to advance Singapore’s energy transition towards a sustainable future.”

News Release Daikin and SP Group Form New Joint Venture to Build Singapore’s Largest Industrial District Cooling System Singapore, 18 May 2022 – Daikin Singapore ("Daikin") and SP Group (“SP”) announced the formation of a new joint venture (JV), in conjunction with an earlier announcement by STMicroelectronics (ST) and SP to establish Singapore’s largest industrial district cooling system for ST’s Ang Mo Kio TechnoPark. The JV will build the district cooling system (DCS) which will have a cooling capacity of up to 36,000 refrigerant tonnes(RT). When completed in 2025, it will help ST achieve 20 per cent savings in cooling-related electricity consumption annually and support ST’s target of achieving carbon neutrality by 2027. Daikin and SP also signed a separate Memorandum of Understanding (MOU) to explore the potential of district cooling in other Southeast Asian countries, starting with Indonesia. Under the MOU, Daikin and SP will combine their expertise, experience and resources to bring this sustainable cooling solution to the various markets to help lower their energy consumption and reduce their carbon footprint. The expanded collaboration between both companies signifies their commitment to empower smart, low-carbon cities across the region, and to support Singapore’s sustainability ambitions under the Singapore Green Plan 20301. “We are excited to collaborate with SP Group, and we look forward to working together closely towards greater environmental sustainability”, said Mr Yoshihiro Mineno, Daikin Industries, Ltd. Moving towards a greener, cleaner future This project aligns with Daikin’s mission to build upon Singapore's ongoing roadmap for greener buildings as well as the longer-term vision for a Singapore Smart-city that includes sustainability in its advocacy. The JV will be 70 percent owned by SP and 30 percent by Daikin. It will build the new district cooling plant for ST Ang Mo Kio (AMK) Technology Park. By centralising chilled water production, the new facility is designed to optimise chiller efficiency and deliver a 24/7 chilled water supply to meet ST’s wafer fabrication needs. In addition, Daikin will be deploying one of its most efficient 2,000-tonne HFO Chiller for this project. HFO or Hydrofluro-Olefins is the new generation of synthetic refrigerants with zero ozone depletion effect and is designed to significantly reduce the Global Warming Potential2. Group Chief Executive Officer of SP Group, Stanley Huang, said, “We are honoured to partner Daikin in this joint venture to provide district cooling to STMicroelectronics at AMK TechnoPark. We look forward to a broader collaboration in Southeast Asia with Daikin.” Reducing carbon footprint and moving towards sustainability In line with the nation’s green vision, Daikin hopes to achieve net-zero by the year 2050 by reducing greenhouse gas emissions and is constantly working towards this goal. The company plans on achieving this by making conscious changes in its entire value chain: life cycle of products, manufacturing, work processes through solution propositions, innovative technologies, and the use of IoT and AI. The ultimate goal here is to contribute toward a cleaner, safer environment to combat climate change issues and move towards a sustainable future. Daikin Singapore has been working with a keen focus on lowering its carbon footprint. As such, the company plans on leveraging its latest chiller software and optimisation expertise3 for this project. Daikin is also planning to launch other green initiatives, including a solution that uses chemical-free water treatment4 that leverages applied electrochemistry and an intelligent controller to enhance system performance, providing a sustainable and scalable solution to large building HVAC systems and industrial chiller circuits, but also saves energy, water, maintenance and chemical costs in cooling water management. Daikin fully supports our national directions and is keen to play an active role in this journey, especially in going Green, Smart and Sustainable in the Living Environment. With this project, we are excited to take another step towards our goals for a sustainable smart nation,” said Mr Liu Shaw Jiun, Daikin Airconditioning Singapore Pte Ltd. Daikin and SP first collaborated back in 2020 to bring Singapore’s first large-scale residential centralised cooling system to the upcoming Tengah HDB Town. Both companies will continue to explore future opportunities to help create energy-saving models and help Singapore and the rest of Southeast Asia move towards a resilient, sustainable future 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.

About Daikin Singapore In the beginning, Daikin Singapore has placed its strategic focus on HDB, building a stronger sales channel by developing Daikin Proshop and thereby differentiating itself from its competitors. With more than 50 years of history in Singapore, Daikin also drove expansion by launching differentiated products such as Remote Monitoring System (RMS), which provides energy optimization and predictive analytics. In Applied Product equipment (AP), which is mainly used in the commercial or industrial sector, it expanded sales by focusing on highly efficient products like magnetic-chiller products and airside using EC motors. Its services business was solely related to the repair and supply of spare parts and since with the acquisition of BMS Engineering, the company has started to focus on Indoor Air Quality (IAQ) and Eco-Friendly Maintenance, where it aims to support green building projects. Daikin will then optimize AC equipment and other building equipment implementation before moving towards providing a full suite of services by adding Energy Management to its portfolio to manage equipment for the whole building. The expansion of Daikin technology and know-how in the cooling industry has enabled Daikin to scale up their green projects to build District Cooling Networks for Tengah and now STMicroelectronics Website: https://www.daikin.com.sg - Ends - 1https://www.greenplan.gov.sg/splash 2https://iopscience.iop.org/article/10.1088/1757-899X/905/1/012070/pdf 3https://www.daikin.com.sg/building-solutions/bms/water-sideoptimisation 4https://www.daikin.com.sg/building-solutions/environmental-solutions/chemical-free-water-treatment

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

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

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

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

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

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

As a player in the EV ecosystem, we want to assure all our partners that Strides’ Electrification-as-a-Service has a suite of solutions to meet their needs. We look forward to our collaboration with SP Group, which will go a long way towards powering our fleet of EVs, which include the electric taxis that are coming our way.” Strides’ EaaS is a suite of end-to-end solutions that include the provision and maintenance of a wide range of electric vehicles, charging infrastructure and a digital management platform. Strides and SP aim to jointly develop innovative solutions that deliver a seamless user experience and help companies and fleet owners accelerate their sustainability plans. SMRT recently announced its plans to convert its entire taxi fleet to 100% electric within the next five years. The first batch of 300 electric taxis is slated to arrive in Singapore progressively from July this year. The electrification of the entire taxi fleet is part of SMRT’s growth strategy in green businesses under its urban mobility services arm, Strides Mobility. SP had earlier signed partnerships with the Goldbell Group, Grab and Schneider Electric to support the charging needs of their EV fleets. In recent months, SP announced a partnership with Chevron to install chargers at four Caltex service stations, and added chargers at locations such as Paya Lebar Quarter, Great World City and Orchid Country Club.
