Media Release SP GROUP AND I-REC HELP CORPORATES ACHIEVE GREEN TARGETS SP’s digital REC platform facilitates greater access to green energy Singapore, 31 October 2019 – SP Group (SP) is the first authorised local issuer of International Renewable Energy Certificates (I-RECs) in Asia Pacific. This independent accreditation by the globally recognised International REC Standard Foundation (I-REC Standard) means consumers can be assured of the integrity of each REC transaction. SP has also enhanced its digital REC trading platform to provide a one-stop solution for buyers and sellers around the globe – regardless of size, business or location – to gain greater access to green energy. In 2018, more than 1,000,000 GWh of renewable energy certificates (RECs) were issued globally, amounting to more than 20 times of Singapore’s annual energy consumption. The challenge to achieving green targets Singapore has a target to increase solar penetration to 350 MWp by 2020 and to reach 2 GWp by 2030 1 . Companies have also set targets to consume renewable energy and reduce carbon emission. In urban places faced with limited land to produce energy from natural resources and inconsistent solar energy, corporates find it a challenge to access sufficient green energy supply. RECs as a solution RECs are a recognised way of achieving renewable energy targets and a credible means to report that the consumed energy comes from renewable energy sources. With each megawatt-hour of green energy produced, one REC is recorded and uniquely numbered and tracked. A buyer can purchase the REC and show proof that he or she consumed green energy. The latest example of using RECs is the sponsorship by SP Group of RECs matching the electricity consumed for the Singapore International Energy Week (SIEW) 2019. SP’s sponsorship means the electricity consumed at SIEW is matched with an equivalent amount of green energy produced. 1 Energy Market Authority of Singapore Media Release – The Future of Singapore’s Energy Story (29 October 2019) 1 I-REC accreditation provides security and integrity assurance SP, as an authorised I-REC local issuer, ensures that a vigorous and transparent attribute tracking system is in place and adherence to best practices. This avoids double counting, double certificate issuance and double attribute claiming. Jared Braslawsky, Secretary General of the International REC Standard Foundation, said: “Reliable information and robust tracking systems are key to ensuring the reliability and integrity of RECs around the world. The I-REC Standard empowers consumers to take responsibility not just for the energy they consumed but also for the origin of the energy consumed. With the support of SP Group, there is a neutral and unprejudiced market facilitator who can play a crucial role in strengthening consumers’ sustainability efforts.” One-stop platform provides ease and convenience SP’s digital REC platform, first introduced in 2018, was designed by its in-house digital engineers to digitally link up buyers and sellers of RECs, making it easier for the trading of RECs. However, sellers had to deal with multiple manual processes to enable the trading of RECs. The enhanced platform provides a seamless one-stop solution which automates the entire process of buying and selling RECs. Speaking at SP’s I-REC Forum in conjunction with the SIEW 2019, May Liew, Head of Sustainability & Open Innovation, SP Group, said: “SP is removing barriers so that big and small organisations can achieve their green targets seamlessly and securely. With our one-stop digital REC platform, they not only have the assurance that the electricity they consume comes from renewable sources, they can also buy and sell RECs without the hassle of dealing with multiple manual processes to issue and verify the RECs.” -Ends- 2 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

Free N95 masks in kits for every home BY ADRIAN LIM E VERY household here will receive three N95 face masks, as part of a nation-wide push to get individuals to think about being prepared for emergencies, such as haze crises and flu pandemics. The 3M brand foldable masks are packed in a “Stay Prepared” kit that will also contain instructions in four languages on how to put them on, and useful emergency contact numbers. A total of 1.2 million kits will be delivered to homes between today and next Monday. The initiative is led by Temasek Cares, a non-profit philantrophic arm under Temasek Holdings, in partnership with Singapore Power and Singapore Post. Temasek Cares will be pumping in $4 million from its $40 million war chest, called the Temasek Emergency Preparedness Fund, for the mask distribution programme. The fund was set up earlier this year to help Singaporeans prepare and deal with emergencies. Last month, a $1.5 million project to train 60 therapists to help children deal with traumatic situations, such as accidents, was also launched. Richard Magnus, chairman of Temasek Cares, said the kits will give households an “initial stock” of masks to encourage them to plan their own contingencies. “It’s a habit of mind we want to prompt... Last June, there was a severe haze that impacted Singapore... we need to be prepared,” said Mr Magnus. The Asean Specialised Meteorological Centre expects this year’s haze to be worse than last year’s. This is because of lower than usual rainfall expected from now till October in parts of the region and the El Nino weather pattern, which is linked to drought, said reports. Being prepared earlier will also prevent a repeat of last June, when people scrambled to stock up on face masks. An additional 17,000 kits will also be delivered to over 140 charity homes, and another 300,000 have been prepared on standby for needy families. Mary Abishagam, 57, a senior administrative assistant with Singapore Power, said she will be volunteering an extra three hours every day, on top of her regular work, to help pack the kits for delivery. “It’s going to be challenging, but we will manage... We are getting people prepared and not many people have thought of keeping masks in their homes,” she said cheerily. Members of the public who wish to get more information about the delivery of the kits can call a hotline, 1800-738-2000, from today until May 24, between 8am and 8pm daily. adrianl@sph.com.sg

IMPORTANT POINTS TO NOTE 3.1. AVOID LAST MINUTE SUBMISSIONS Suppliers are encouraged to familiarise themselves with the SPSRM System when they are granted access by way of a User ID and password. Early bid submissions are strongly encouraged. Last minute submissions may induce panic and this increases risk of failure to submit on time. Moreover, if Suppliers encounter any issues while submitting their bids and need to seek our assistance (Contact Us), there may not be sufficient time for us to provide help. Bid submissions after the submission deadline will not be accepted. __________________________________________________________________________________ 3.2. DO NOT LOG IN AT MULTIPLE LOCATIONS WITH A USER ID Do not log in at multiple locations* with a User ID at the same time. *The following are examples of multiple locations login: e.g.1: At two or more computers and logged in at all respective computers’ browser e.g.2: On a single computer but logged in at two or more different browsers (e.g. Chrome and Safari) Multiple logins with a single User ID may trigger the security feature to lock down the User ID, preventing activities within SPSRM. The time-out for the User ID to be unlocked may take up to 15 minutes from the last activity performed with the User ID. __________________________________________________________________________________ 3.3. ALWAYS CLOSE ALL BROWSER WINDOWS AFTER LOGGING OUT OF SRM Suppliers are recommended to close all browser windows after logging out of SRM. This will ensure the session’s cookies/cache is fully cleared. __________________________________________________________________________________ 3.4. UPDATING DOCUMENT CONTENT (REFRESH) The Refresh button may be used to update content in a particular area or the entire document. For faster update processing, it is recommended to use the Refresh button if it is available within the window (avoid using the browser’s refresh function). The Refresh button may be displayed in icon or in text: __________________________________________________________________________________ Page 7 of 78 S SRM User Guide Version 1.04 (Apr 2022) 3.5. AVOID USE OF BROWSER’S CLOSE BUTTON Note: Use the browser’s Close button only if there is no Close button within the window. Using the browser’s Close button may terminate the system’s processing prematurely. As the processing was interrupted, the system may not recognise the activity has been completed and this will lock the SPSRM document that was closed with the browser’s Close button. It may take up to 15 minutes for the lock to time out. To prevent this, use the Close button within the window if available. The pop-up box on the right will be displayed in two scenarios: i. The document in edit mode is already opened in another browser window. Solution: Check through the browser windows for the same document and continue with the required activities at that window. ii. The document was previously closed with the browser’s Close button. Solution: Check that there was no other opened browser window for the document. If so, wait for 15 minutes for the lock to time out before proceeding with the required activities again. __________________________________________________________________________________ Page 8 of 78 S SRM User Guide Version 1.04 (Apr 2022) 3.6. VERIFY TRANSACTION WAS SUCCESSFUL To detect unexpected error/failure, for important transactions, please verify the transaction was successful. For example: Response submission, please refresh the RFx List and check that the Response Number column against the RFx has a number and the Response Status is “Submitted”. Successful submissions will have RFx Response number with “Submitted” status __________________________________________________________________________________ 3.7. SYSTEM MESSAGES System messages are displayed at the top of the screen. __________________________________________________________________________________ 3.7.1. Error messages Error messages are indicated with the red icon . All errors in the document must be resolved before submission is allowed.

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.

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.

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.

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.
