4 | The T OP STORIES SP Group acquires rooftop solar assets in China Business Times | Tuesday, April 11, 2023 By Natalie Chen HM nataliechen@sph.com.sg SP Group announced on Monday (Apr 10) that it has acquired up to 150 megawatts-peak (MWp) of rooftop photovoltaic (PV) assets from China’s Shanghai Unisun New Energy. In a press release, SP Group – an energy utilities group and sustainable energy solutions provider – said that the solar assets will generate more than 150 gigawatt-hours (GWh) of green electricity annually. This will help China avoid more than 88,000 tonnes in carbon emissions each year. The 150 MWp of rooftop PV assets are solar panels which convert light to electricity. The two companies have already completed the acquisition of the first 80 MWp of distributed PV projects for a total equity consideration of S$34 million. These assets are installed at over 50 industrial sites in Fujian, Jiangsu, Zhejiang, and Guangdong, covering the food and beverage, automobile and textiles industries. The transaction for the remaining 70 MWp is likely to be completed by the middle of this year. SP Group said the acquisition is in line with its strategy towards sustainable development and decarbonisation of the industrial sector, reducing energy consumption and carbon footprint of manufacturing facilities. “The acquisition is part of SP Group’s long-term commitment to support China’s clean energy expansion and strengthen our sustainable energy portfolio”, said Michael Zhong, SP Group China managing director. “We look forward to accelerating the green energy transition and sustainable development for industrial parks, districts, and townships across China through deeper partnerships and value-added innovations”. SP Group recently formed alliances with China Southern Network Financial Leasing, CGN International Financial Leasing and CIMC Capital, to jointly invest and develop sustainable energy projects in new energy development, energy storage systems and integrated energy managements. China has pledged to peak carbon emissions by 2030 and achieve carbon neutrality by 2060, as announced by President Xi Jinping in September 2020. According to a report by the International Energy Agency in September 2021, the pace of China’s emissions reductions will be an important factor in global efforts to limit global warming to 1.5 deg C.

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

News Release SP GROUP EXPANDS MARINA BAY DISTRICT COOLING NETWORK WITH NEW PARTNERSHIPS • 8 Shenton Way, IOI Central Boulevard Towers, 80 Anson Road, Marina Bay Sands Integrated Resort Expansion and NS Square, will be connected to the world’s largest underground district cooling network • Sustainable cooling solution helps Marina Bay avoid almost 20,000 tonnes of carbon emissions annually Singapore, 20 April 2022 – SP Group (SP) announced that it will be providing its energy efficient district cooling services to five upcoming new and retrofit developments – 8 Shenton Way (formerly AXA Tower), the commercial component of 80 Anson Road (formerly Fuji Xerox Towers), IOI Central Boulevard Towers, Marina Bay Sands Integrated Resort Expansion and NS Square – through its Marina Bay District Cooling Network. Marina Bay is planned as a sustainable live-work-play district, and all developments are served by a comprehensive underground network of common services tunnels that houses the district cooling system. 1 The addition of the five developments will further expand the world’s largest underground district cooling network, bringing the total number of buildings served by SP’s Marina Bay operations to 28. SP’s sustainable cooling solution will help the Marina Bay district reduce its carbon emissions by 19,439 tonnes annually while providing the same cool comfort. This is equivalent to removing 17,672 cars off our roads. At an appreciation event held earlier today which marked the expansion of the Marina Bay District Cooling network, Mr Desmond Lee, Minister for National Development and Minister-in-charge of Social Services Integration, presented certificates of appreciation to 1 District cooling in Marina Bay provides centralised cooling to developments in the area. There are two district cooling plants in Marina Bay, both situated underground and seamlessly integrated with the surrounding developments, providing greater reliability of services and allows more efficient use of energy across the district. SP Group operates the district cooling network in Marina Bay. 1 the building owners of the five buildings – City Developments Limited (CDL), IOI Properties, Marina Bay Sands Singapore, NS Square, and Perennial Holdings – affirming their commitment to the sustainable development of our city centre. Through subscribing to district cooling, the new developments will enjoy reliable cooling comfort with the network achieving zero supply interruptions since the Marina Bay District Cooling operations started in 2006. Without the need to invest in their own chillers, the new developments will enjoy a lower initial investment cost compared to a conventional air-conditioning system. The savings on equipment, operating and maintenance costs will also reduce the total cost of ownership by up to 15 per cent. Having centralised chiller plants also frees up prime space for other commercial or lifestyle purposes, potentially increasing asset yield for building owners. SP’s Group Chief Executive Officer, Mr Stanley Huang, said, “SP Group is the largest district cooling solutions provider in Singapore. With the expanded infrastructure in place, we are pleased to extend the same reliable and sustainable solution to other buildings in Singapore’s core financial district and look forward to welcoming more partners to this network. Together, we can accelerate the development of greener buildings and cities to achieve Singapore’s ambitious sustainability targets.” In addition to the energy savings and the reduction in carbon emissions, developments will also benefit from the centralisation of ownership and maintenance of their cooling systems under a district cooling operator, ensuring optimal operations at all times. SP as the district cooling operator is responsible for meeting the industry sustainability standards. Under the latest BCA Green Mark 2021 (GM: 2021) green building certification scheme, buildings supplied by an external district cooling system (DCS) plant have a dedicated pathway to demonstrate their energy efficiency performance, allowing for a more seamless certification experience. With the inclusion of these new customers, SP will be increasing the capacity of its Marina Bay district cooling network to 70,000 refrigerant tons (RT). It will also add more than two 2 kilometres of underground insulated pipes to the network to cater to the additional demand and cooling capacity. To further enhance the reliability of the network, SP is exploring installing thermal storage tanks in the neighbouring Central Business District to increase the network’s energy storage capacity. These auxiliary chilled water tanks will enable the existing network to significantly reduce its peak load consumption and support future expansion of the cooling network beyond the Marina Bay vicinity. Additional energy storage capacity will also facilitate the incorporation of more renewable energy sources to the grid by mitigating the intermittency of renewables while maintaining grid stability and reliability. The deployment of energy storage systems, such as thermal storage tanks, is in line with government’s energy storage target and vision of a clean and efficient energy future. SP continues to actively engage with potential customers to further expand the Marina Bay district cooling network. It is currently studying the feasibility of M Hotel Singapore, a hotel under the CDL Group, being the first brownfield hotel development to incorporate district cooling in its operations. In addition to the Marina Bay district cooling network, SP is also collaborating with the Housing and Development Board (HDB) to deploy Singapore’s first residential centralised cooling system for up to 22,000 households at the upcoming Tengah housing estate by 2023. SP will also be developing Singapore’s first brownfield, sustainable cooling solution for a town centre at Tampines.
