News Release UOB and SP Group partner to offset 100% or more of household electricity carbon emissions for UOB EVOL cardholders Cardholders can now achieve their sustainability goals seamlessly and conveniently when they charge their utilities bills to their card Singapore, 23 November 2022 – UOB EVOL cardholders will now be able to offset 100 per cent or more of their household electricity carbon footprint for free when they charge SP Group’s (SP) utilities bills to their credit card, via a new exclusive feature jointly launched by UOB and SP this month. With this new feature, when customers charge SP utilities bills to their UOB EVOL card, UOB will fund and contribute 2 per cent of the billed amount to purchase My Green Credits on the SP app on behalf of the customer. My Green Credits is an affordable and convenient way for customers to get on the sustainability movement by greening their energy consumption through the purchase the amount of “green credits” in the form of Renewable Energy Certificates (RECs)1. For example, when customers charge a $90 utilities bill to their UOB EVOL card, they will receive $1.80 worth of complimentary My Green Credits from UOB, equivalent to 2% of the billed amount. My Green Credits is purchased at a cost of S$0.12 per 25 kWh, which will translate to offsetting 375 kWh (kilowatt hour) or equivalent to an average national 4-room HDB flat’s electricity usage. This is equivalent to offsetting 100 per cent of the home’s electricity carbon footprint (see Annex for illustration). New UOB EVOL cardmembers paying their SP bills via the SP app will automatically enjoy the complimentary My Green Credits, while existing cardholders who are using the SP app to pay their bills before 10 November 2022 will simply need to do a one-time re-add of their EVOL card as a payment method to be eligible. My Green Credits will be automatically reflected within the customer’s SP app, with no additional effort required from them when bill payments are made. This benefit is available for both one-time and recurring SP bills payments. UOB EVOL card is the first in the market to partner with SP Group, Singapore’s national grid operator and leading sustainable energy solutions provider in the region, to offer customers complimentary My Green Credits when they use their EVOL Card to make utilities payment. This feature is applicable to all existing and new EVOL cardholders. The My Green Credits purchased will go towards supporting sustainable energy project developments in the region for the generation of green energy. 1Renewable Energy Certificates (RECs) are tradable green energy attributes that represent units of electricity generated from renewable energy generation facilities. These facilities comply with and are registered under internationally recognised standards, such as the I-REC standard, and are eligible to be issued RECs for every unit of electricity generated. A credit card that supports the green initiative UOB EVOL card is designed to appeal and serve the needs of younger customers, particularly their increasing focus on sustainability. The UOB EVOL Card is Southeast Asia’s first credit card to use bio-sourced materials to minimise ecological footprint. The EVOL Card is made of 84 percent polylactic acid (PLA) and created from renewable sources which are safe for incineration process. An EVOL Card that has expired and discarded is biodegradable in an industrial facility. Each EVOL card cuts down the use of plastic by 84 per cent and reduces carbon footprint by 10 grams per card. EVOL card also has a strong partnership with over 30 green partners to increase customers’ awareness of sustainability in their daily spending. This new card feature is another innovative initiative to further help them contribute to sustainable efforts seamlessly and conveniently. Ms Jacquelyn Tan, Head of Group Personal Financial Services, UOB, said “We understand that every customer has unique needs, preferences and goals, and this drives us to do right by them, to serve them in a way that meets their needs. Our wide suite of credit cards provides a comprehensive range of benefits and rewards to cater to different groups of customers on their differing needs. Through our partnership with SP, we are happy to further support the younger generation’s sustainability goals with our UOB EVOL card. This also shows UOB’s commitment towards sustainability, as we empower customers to work with us to tackle climate change and to forge a more sustainable future together.” Mr Luke Tang, Head of Strategy and Sustainability, SP Group, said “We are pleased to partner UOB to catalyse behaviour that promotes sustainability and the use of renewable energy certificates on the SP App to green household electricity consumption. As younger customers chart their sustainability journeys, we look forward to empowering them with green platforms and resources and collectively accelerate Singapore’s progress towards net zero.” The SP app was launched by SP as the first sustainability lifestyle app in Singapore. It aims to incorporate green solutions and initiatives to provide users with insights and solutions to manage their utilities and to reduce their carbon footprint. In addition to My Green Credits, users can also use the app to manage their utilities, reduce electricity consumption and contribute to Singapore’s sustainability targets to achieve a low-carbon future. On another sustainable front, as part of the UOB EVOL Card My Green Credits launch, SP supported National Parks Board’s (NParks) OneMillionTrees movement to plant a million more trees across Singapore by 2030 through NParks’ registered charity and IPC, Garden City Fund’s Plant-A-Tree programme. UOB and SP will plant 50 trees in April 2023, bringing us closer to realising our vision of becoming a City in Nature, a key pillar of the Singapore Green Plan 2030. Strategic partnership to create better solutions for customers This year marks the fourth year of partnership between UOB and SP, with joint efforts to empower customers on their green goals. Previous collaborations include the purchase of RECs through SP as part of a National Day promotion in 2021 for the EVOL card. UOB has also launched an API with SP in 2020, to allow UOB customers to instantly use their UNI$ to off-set their utility bills. Moving forward, UOB will work with SP to launch another new feature in the first quarter of 2023 that allows UOB cardholders to use their UNI$ to redeem for My Green Credits via the SP mobile app. They can choose which local or international renewable energy projects that they would like to support with the My Green Credits redeemed. Under the My Green Credits initiative, SP is supporting various green projects ranging from a solar farm in Vietnam, to a wind farm in Thailand, to a solar rooftop system in Singapore, to help reduce emissions and impact on the environment. In line with Singapore’s strong push to electrify its vehicle population, ecosystem, UOB and SP also have plans to provide promotional offers to customers who use their UOB cards to pay for electric vehicles (EV) charging at SP EV charging points. Over the past 2 years, UOB has been building up a suite of sustainable future solutions to make it simpler for customers to create impact with their everyday choices. The Bank has an established sustainable investing approach which set standards for its Singapore and regional footprint by curating a suite of sustainable investments across funds, bonds and structured products.

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.

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.

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.

GAS TRANSPORTATION TARIFFS (for Shippers with customers off-taking natural gas at high pressure) (W.E.F. 1 Apr 25) 1 Introduction 1.1 Under the Gas Network Code, PowerGas is the Gas Transporter and is responsible for maintaining the reliability and safety of the gas transportation network in Singapore. PowerGas’ transportation business is regulated by the Energy Market Authority (EMA). The transportation tariffs levied by PowerGas are approved by the EMA. 1.2 PowerGas charges transportation tariffs for the transport of gas through its network. PowerGas’ transportation tariffs are levied on Shippers and not the end-users. End-users’ transportation charges imposed by Shippers are commercial arrangements between both parties. 2 Natural Gas Transmission Tariffs 2.1 There are two gas transmission networks, namely Transmission Network 1 and Transmission Network 2. Transmission Network 1 refers to the natural gas transmission network conveying both piped natural gas and regasified LNG from West Natuna (Indonesia) and the LNG Terminal. Transmission Network 2 is the natural gas transmission network conveying both piped natural gas and regasified LNG from South Sumatra (Indonesia), Attap Valley (Malaysia) and the LNG Terminal. 2.2 Transmission tariffs consist of capacity and usage charges (refer to Section 3 below for details). These charges are applicable to Shippers off-taking gas at high pressure. The same charging structure also applies to Shippers with Small Transmission Customers (i.e. with load less than or equal to 5 bbtud). 3 Transmission Charging Structure 3.1 Shippers book capacity with PowerGas to transport gas from designated injection points to off-take points. Shippers pay entry and exit charges based on their respective booked capacity. In addition, a usage charge is levied on the volume of gas transported. 3.2 Arising from EMA’s notification to the industry dated 21 March 2024, a GSC of 22 cents/mmBtu for PNG Injection Points or GSC of 3 cents/mmBtu for LNG Injection Points is imposed on PNG and LNG gas users respectively with effect from 1 Apr 25 to recover the cost associated with Strategic Capacity (as defined in EMA's Policy Paper issued to the industry dated 30 Sep 2019). The Transporter will collect the GSC from all Shippers as an agent for and on behalf of SLNG. The GSC will be reviewed from time to time as directed by EMA and will be included as an uplift in the usage charge. Details of the transmission charges are shown in Table 1 of the Appendix. 3.3 These transmission charges do not include specific cost items which need to be determined on a case-by-case basis for inclusion into the final transmission charges. 3.4 For Shippers with Small Transmission Customers (i.e. requiring gas at high pressure, but with load of less than or equal to 5 bbtud), the transportation charges as shown in Table 2 of the appendix shall apply. 3.5 Shippers will have to pay Overrun Charges in the event they off-take gas above their booked capacity. These Overrun Charges are necessary to encourage the efficient use of the gas network. There are two types of Overrun Charges: • Authorised Capacity Overrun Charge: If a Shipper applies for additional capacity above the booked capacity (i.e. capacity overrun), the Authorised Capacity Overrun Charge, equivalent to 1.25 times the Transmission Capacity Charge rate, shall be applied on that additional capacity. 2 • Unauthorised Capacity Overrun Charge: If a Shipper does not apply for Authorised Capacity Overrun for utilisation of additional capacity above the booked capacity, it will pay 2 times the Transmission Capacity Charge rate for that additional capacity utilised. 4 Appendix – Table of Charges Transmission Network 1 (locational) Transmission Network 2 (locational) Table 1: Transmission Charges (Exclusive of GST) Entry Capacity Charge per annum ($/MMBtu/hr) Exit Capacity Charge per annum ($/MMBtu/hr/km) Transmission Usage Charge ($/MMBtu) 891.91 57.94 0.0087 1,503.65 (Attap Valley Injection Point) 1,093.61 (Sakra Injection Point) 43.07 0.0132 New Pipeline – utilised 276.51 276.51* 0.0034 New Pipeline – excess 232.31 232.31* 0.0041 GSC for PNG Injection Point N.A.
