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. This includes its first UOB Personal Financial Services (PFS) secured loans green product framework, serving as the foundation of its Go Green home and car loans. The framework leverages insight from Morningstar Sustainalytics, a leading global provider of ESG research, ratings, and data. In November 2022, UOB also will be availing a digital doorway to sustainable banking on the UOB TMRW app, allowing customers to easily access green deals, investments and banking products on mobile. Through the app, customers will also receive eco-friendly tips for the holiday festivities, and personalised insights to bank and live more sustainably in 2023.   ANNEX: Illustration of offsetting customers’ carbon footprint with UOB EVOL Card

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.”

General Information 1.1 Purpose of this Document PowerGas is licensed by the Energy Market Authority (“Authority”) to be the Gas Transporter (“Transporter”) which owns, operates, and maintains the piped gas network in Singapore. SP PowerGrid (“SPPG”) is licensed by the Authority to be the Gas Transporter Agent to operate and maintain the piped gas network in Singapore on behalf of PowerGas. SPPG’s gas business is to plan, design, operate and maintain gas network assets in a manner that supports the delivery of safe, reliable, efficient, and quality services to customers. Under the Gas Transporter Licence, the Gas Transporter has to develop separate fees and charges for separate gas transportation services such as connection services and transportation services. This document sets out the connection policy and procedure for Natural Gas supply. 1.2 Singapore Gas Transportation System PowerGas owns an extensive gas transmission and distribution network throughout Singapore. The network is generally buried underground and transports natural gas to the western and northern parts of Singapore, and town gas to the whole of Singapore. The gas assets comprise the transmission network (operating at higher pressures), which forms the main reticulation backbone and the distribution network (operating at lower pressures). • Town gas is manufactured in Senoko Gasworks and delivered to approximately 900,000 customers in Singapore. The customers are made up of industrial, commercial, and residential gas users. Residential customers consist mainly of gas users from HDB, condominiums and landed premises. The town gas transmission network operates at 3 barg whereas the distribution network operates at pressure regimes ranging from 1 kPa to 50 kPa. Natural gas is supplied to about 200 customers and is imported from four sources (two submarine pipelines from Indonesia, one submarine pipeline from Malaysia and internationally through the Liquefied Natural Gas Terminal). Under the Gas Network Code, Gas Shippers/Retailers represent the customers that are connected to the natural gas networks. These natural gas customers are typically commercial or industrial and include all power stations. The natural gas transmission network operates mainly at two pressure regimes, 28 barg and 40 barg, and the distribution network operates at pressure regimes ranging from 3 barg to 6 barg.

Charges 4.1 Connection Policy The cost to connect a customer’s gas installation or gas fitting to the Transporter’s gas pipeline network varies from case-to-case, due to the proximity of the customer’s location and the cost of the materials and services required for the gas connection. Where possible, the Transporter will envisage to propose the most cost-effective connection to the applicant. 4.2 Connection Charge The connection charge payable for all gas connection applications is the sum of the project cost less the deductible cost, subject to a minimum connection charge of zero. The description of each of the cost components are shown below. (1) Project cost All costs related to the provision of gas connection from the Transporter’s gas pipeline network to the GSIV, including the Meter Installation (where applicable). (2) Deductible cost The Transporter’s investment value based on the committed gas demand from the applicant for the new gas connection. For distribution connections, the investment value is derived based on the net present value of the 5-Year revenue of the average consumption for each consumption category (see Appendix 8). For transmission connections, the connection charges are calculated individually on a case-bycase basis. In addition, a Last Mile Connection Charge (“LMCC”) will be levied to recover the cost of the “last mile” connection of the gas installation to the GSIV from the applicant. The natural gas transmission/distribution connection deductible cost, LMCC and unit rates used in the determination of the transmission/distribution pipeline estimated capital investment shall be reviewed and adjusted when deemed necessary by the Transporter. The Transporter reserves the right to review the connection charge paid for any new connection and seek reimbursement for the first 5 years under-recovered revenue from the Shipper/Retailer if the actual gas consumption after 5 years of operation is more than 10% below the projected gas demand declared during application.
