News Release SP Group building the first large-scale underground substation in Southeast Asia Singapore, 6 April 2021 – SP Group (SP) is constructing the first large-scale underground substation in Southeast Asia. Located at Labrador, SP will build its 230kV1 electrical substation underground to optimise space in land-scarce Singapore for urban growth and development. Group Chief Executive Officer of SP Group, Stanley Huang, said: “In our business of enabling a low carbon, smart energy future, we are building sustainable and resilient infrastructure. Taking a holistic approach, we are constructing this substation underground, freeing up space above for a 34-storey development. This is in line with Singapore’s urban renewal plans and our own SDG2 goals of ensuring access to reliable, sustainable and modern energy for all and tapping on innovation to build sustainable infrastructure.” Substations are part of essential infrastructure that power homes, offices, industries and public services. By freeing up prime land spaces for residential, commercial or recreational purposes, land use and resources can be optimised. By going underground, the Labrador substation alone will free up three hectares of prime land space, or the equivalent of four football fields. When in service, the substation will serve the electricity needs of nearby towns such as Alexandra, Clementi, Keppel, Pasir Panjang, and the Science Park district. Typically, building a substation underground would be more resource-intensive and require specialised engineering capabilities as compared to above-ground. This is due to complexities in construction and the need to use materials and equipment that are suitable for subterranean environment. For example, detailed engineering studies and suitable construction methods are implemented to control the impact to the surrounding buildings and infrastructure. In addition, the equipment in the substation must be of low-fire risk, with cooling systems installed to prevent the build-up of heat in the equipment. The long-term benefits of building substations underground outweigh the costs. In addition to optimising land resources for other purposes, underground substations have a lower risk of being exposed and damaged. This will enhance asset and network security. Mr. Huang added: “Leveraging our extensive experience in constructing the underground electricity cable tunnels that span across Singapore, we will be able to deal with the complexities of building this underground substation. With the learnings and experience gathered from this project, we can explore the possibilities of housing more substations underground.” The Labrador underground substation is part of the Urban Redevelopment Authority’s underground Master Plan 2019. The electricity substation at Labrador and the commercial building are scheduled for completion in 2024. SP today announced that it has awarded the building contract of the substation to main contractor Hyundai Engineering & Construction Co. Ltd. 1 Electrical transmission substations range between 66kV to 400kV. When running at full capacity, one 230kV substation can power up to eight towns, each the size of Toa Payoh. 2 United Nation’s Sustainable Development Goals -Ends- About SP Group SP Group is a leading utilities group in the Asia Pacific, enabling a low-carbon, smart energy future for its customers.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Powering Tengah, Singapore’s First AI-enabled, Eco-friendly, Smart Energy Town SUSTAINABILITY Speakers and moderator at the virtual Ecosperity Conversations on “Sustainable Districts for a Sustainable City”. Photo credits: Temasek How can we enhance livability, sustainability and resilience of our cities through urban planning and urban innovation? This was explored at the first virtual Ecosperity Conversations session held by Temasek on 24 June 2020. SP Group’s S Harsha, Managing Director of Singapore Markets in Sustainable Energy Solutions joined Dr. Limin Hee, Director of Research at Singapore’s Centre for Liveable Cities, Frederick Teo, Director and Soh Hui Qing, Associate Director of Sustainability and Stewardship Group at Temasek. They exchanged ideas on how district-level projects could be testbeds for the national roll-out of sustainable energy solutions. Citing the collaboration between SP Group and the Housing Development Board at Tengah, Harsha opined that the careful integration of “eco-innovations” can transform this new town into an AI-enabled and sustainability-focused eco-town of the future. These “eco-innovations” include the world’s first large-scale residential Centralised Cooling System (CCS); vertically deployed building-infused photovoltaic systems; electric vehicle fast charging hubs coupled with battery energy storage systems; and digital solutions designed for residents and municipal operators. Here are some interesting Q&As captured during Harsha’s interaction with the audience: How do you promote CCS, given that it is just an option to the residents? Harsha: We’ve been engaging Tengah residents fairly early in their home purchase journey. We talk to them during the lease signing and even unit selection phase. Since August last year, we’ve engaged close to 2,000 dwelling units and we continue to see a high interest level towards CCS. It’s very encouraging and we are aiming for at least 80% of our residents to opt for CCS! We have limited rooftop space on HDB blocks. How can one free up space to harness renewable energy? Harsha: One of the early innovations we are bringing into Tengah is the building-integrated photovoltaics whereby solar panels will be deployed vertically on the crown of the HDB blocks. They’re not going to be as efficient as the RC rooftop solar panels but we will give it our best shot to harness as much renewable energy as possible and route it back to CCS. Are you also implementing other circular economy concepts in Tengah? Harsha: We’re exploring the possibility of implementing our zero-waste gasification system which piloted at Gardens by the Bay in Tengah’s residential context. This gasification system converts waste into thermal energy and biochar (carbonised biomass). The process also emits a lot of synthesis gas that can be used for thermal heating. Instead of Sembawang Hot Springs, perhaps we can have our own Tengah Hot Springs? Well, that’s a crazy idea I have at the back of my mind. Graphic recording of the webinar.

This can be achieved through the collective efforts of residents, municipal operators, and businesses as they advance towards sustainability together. — 6 August 2020 TAGS #SUSTAINABILITY #ECOSPERITY #TENGAH YOU MIGHT BE INTERESTED TO READ SP Group launches Tengah’s First Public EV Chargers, Expanding Singapore’s Green Mobility Network SP Group secures district cooling and heating energy management project at Chengdu Future Medical City SP inks MOU with Wuhou government to develop an integrated energy management project in the Wisdom Valley

THE STRAITS TIMES BRANDED CONTENT Purpose-driven tech: Meet the UX designer on a mission to help the planet and the community Whether she is enabling consumers to visualise their personal carbon footprint or doing user research to encourage volunteering, SP Group’s Director of User Experience Priscilla Liu strives to make a positive impact Ms Priscilla Liu, who heads the User Experience team at SP Group, is optimistic about helping consumers understand the difference they can make on a personal level in combating climate change. PHOTO: SP GROUP PUBLISHED MAR 8, 2023, 4:00 AM SGT Can one less plastic bag or a night without air-conditioning actually make a difference in climate change? This is a question that prompted Ms Priscilla Liu to find ways for everyone to chip in to counter the effects of climate change. “On a smaller level, we all know there are some things we should or should not do. But climate change is a concept of such a big scale that people are sceptical that one person’s action can really affect anything. And that is the problem we are trying to solve,” shares Ms Liu, Director of User Experience at SP Group (SP). One way is to let individuals measure and see the tangible impact of his or her actions. That’s what Ms Liu and SP’s team of digital experts set out to do when designing the SP app. The app’s 1.4 million registered users can see almost in real time how their daily habits affect their electricity consumption. “Typically, we get our utilities bill at the end of the month – by then, it’s too late to change our behaviour,” explains Ms Liu. “But with the SP app, smart metering shows electricity consumption information that refreshes every half hour. It’s easier to link what activity consumes how much energy and motivate changes to behaviours.” Climate-friendly features on the SP app Ms Liu also takes pride in another climate-oriented feature in the SP app – GreenUP. Through gamification, it encourages users to learn more about sustainability and take steps to incorporate it into their daily life. Users can collect points known as “leaves”, accumulate them to grow a virtual plant, and enjoy tiered rewards and discounts with partner merchants. “GreenUP began as a project to encourage users to take small steps towards a greener lifestyle. It is now one of the features with the highest engagement rate on the SP app,” says Ms Liu, “If we all take small steps to behave sustainably, that can have a significant cumulative effect.” Another feature on the SP app is My Carbon Footprint, which helps consumers calculate their carbon emissions to quantify their personal carbon footprint and suggest ways to reduce it. For example, it can propose Green Goals for users to reduce their consumption of energy and water. The Green Goals feature is calibrated according to the average consumption in the consumer’s district, benchmarked against the national consumption, and weighted according to the profile of the household. This way, the consumer benefits from a detailed and realistic analysis of their consumption patterns. Ms Liu’s team is responsible for presenting the consumption data in a visually engaging and easily understandable manner. This helps consumers appreciate their individual contribution within the larger community and national efforts for climate action. “Sustainability is everyone’s responsibility. We hope that through good digital design, we are able to increase engagement and encourage more consumers to take steps in reducing their carbon footprint,” says Ms Liu. These climate-conscious actions will contribute towards Singapore’s goal of net zero carbon emissions by 2050. Ms Liu is confident that Singapore can meet the target. “If there’s one thing that Singapore is good at, it’s meeting targets,” she says. Working and volunteering for a higher purpose Ms Priscilla Liu (first row, seventh from left) and fellow volunteers from SP Heart Workers and Yio Chu Kang Zone 2 RC preparing to distribute bags of daily essential items to 150 families and seniors during Hari Raya last year. PHOTO: SP GROUP When Ms Liu first joined SP Group more than six years ago, she had already accumulated skills and expertise in user experience (UX) at various multinational companies, including an Australian bank and a real estate group. “I was attracted to how SP Group made the decision to go into sustainability before it was trendy. The energy industry is complex and there are many uncertainties to consider, so it is quite bold of them to venture into areas like electric vehicle charging and solar energy as a forerunner back then. “Also, after many years of building apps to sell things, I wanted to do something more meaningful in my career. SP Group gave me the opportunity to work on something that makes a positive impact,” says Ms Liu. Besides her work responsibilities on the UX team, Ms Liu is also the Chairperson for SP Heart Workers, SP Group’s corporate volunteering programme. Activities organised under this programme include charity drives, social events and activities for the elderly, as well as packing and delivery of learning tools for children. During one of the events, staff volunteers from SP were paired with elderly folks to shop for groceries with SP-sponsored vouchers at the supermarket. “Usually, they buy items that they can keep for a longer time, such as canned food. And they also tend to pick cheaper items. But one time, I remember vividly that this auntie took a box of chocolates, which was out of the norm. At the checkout she told us, ‘This chocolate is for the volunteers.’ It was a really touching moment for me,” recalls Ms Liu. Ms Liu has also put her UX skill set to good use for SP Heart Workers. “We do ‘user research’ – we get feedback from volunteers and improve the volunteering activities with each iteration. We also ensure each programme has clear objectives and desired outcomes are achieved, so that our efforts are meaningful and well received by those we volunteer with, and colleagues have an overall positive experience and are encouraged to volunteer more.” Join ST's Telegram channel and get the latest breaking news delivered to you. � E-paper � Facebook � Instagram � Twitter � LinkedIn � Podcasts � RSS Feed � Telegram � Youtube � TikTok • SINGAPORE • ASIA • WORLD • OPINION • LIFE • TECH • SPORT • VIDEOS • PODCASTS • MULTIMEDIA • BUSINESS About Us Terms & Conditions Need help?

MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 OCTOBER TO 31 DECEMBER 2022 Singapore, 30 September 2022 – For the period from 1 October to 31 December 2022, electricity tariff (before 7% GST) will decrease by an average of 1.4% or 0.42 cent per kWh compared with the previous quarter. This is due to lower energy costs compared with the previous quarter. For households, the electricity tariff (before 7% GST) will decrease from 30.17 to 29.74 cents per kWh for the period 1 October to 31 December 2022. The average monthly electricity bill for families living in HDB four-room flats will decrease by $1.55 (before 7% GST). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA).

Sembcorp Industries and SP Group to jointly develop environmental sustainability platform Felicia Tan Published on Tue, Oct 27, 2020 / 8:10 AM GMT+8 / Updated 6 days ago A- A A+ Sembcorp Industries (Sembcorp) and SP Group are collaborating to develop an environmental sustainability platform to help corporates and consumers achieve their sustainability goals. Through the platform, both Sembcorp and SP Group will provide consultancy services encompassing physical and digital solutions across energy, water and waste management to enable corporates to achieve their greenhouse gas emissions (GHG) reduction targets. This comes amid accelerating momentum for climate change. In 2015, Singapore has also pledged to reduce emission intensity by 36% from levels in 2005 in 2030 and to stabilise emissions with the aim of peaking in the same year. The platform, a one-stop global solution, aims to include a market place that trades renewable energy certificates (RECs) and carbon credits as well as provide carbon consulting services. See also: Sembcorp Industries launches fund to support community development with initial injection of $1.5 mil RECs are a way of achieving green targets and a credible means for buyers to track that their consumed energy comes from renewable energy sources. Carbon credits are tradable certificates that allow buyers to offset their GHG by supporting projects aimed at reducing GHG emissions. Carbon consulting services include analysis, advisory and strategy development to assist corporates in achieving their carbon emission reduction targets. The launch of the platform will take place in 1Q2021. “This platform complements SP Group’s full suite of sustainable energy solutions that enable individuals and corporates to achieve a low-carbon, smart energy future. We contribute through deep experience and a strong track record of serving our strong base of 1.6 million industrial, commercial and residential customers in Singapore and the region, as well as operating the world’s first blockchain-powered RECs platform,” says Stanley Huang, Group CEO of SP Group. Wong Kim Yin, Sembcorp’s group president and CEO adds, “Our partnership with SP is timely as more customers pivot towards low-carbon energy goals. We are well positioned to add value through our strong global energy expertise, digital innovation and renewables portfolio. This offering, together with the 2,600MW renewable energy assets we have developed across key markets, enables Sembcorp and our customers to contribute actively towards a sustainable future.” Shares in Sembcorp closed 3 cents higher or 2.1% up at $1.48 on Oct 26.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Soaring beyond legal limits SUSTAINABILITY From the courtroom to the boardroom, former litigation lawyer Lydia binte Yahaya left private practice to be part of SP Group’s in-house legal counsel team in 2018. It’s a new playing field for Lydia, viewing her role as “more than just a lawyer”. Conducting contractual negotiations on behalf of the organisation and advising on corporate risks are all in a day’s work. One of the most rewarding aspects of her job is to champion sustainable business practices, a cause that is close to her heart. With growing awareness of her own carbon footprint, Lydia supports food products that are sustainably sourced and has joined in the #sustainablefashion movement. Now, she never leaves home without her metal straws, including one for her bubble tea indulgence! Lydia Binte Yahaya, Deputy Director of Legal and Corporate Secretariat at SP Group offers legal guidance and support for Electricity and Gas businesses, Sustainable Energy Solutions and corporate functions.  The 34-year-old overcame the steep learning curve when she switched from private to in-house practice. At SP, she is exposed to the workings of an operating business, where her legal expertise will help protect the interests and reputation of the company. “When I was working in a law firm, the deliverables are more specific. For example, your primary role can be to prepare court documents and provide legal advice to clients. Now, I have to put on both commercial and legal hats. The experience made me appreciate legal services as an integral part of a commercial entity.” “Assisting in some of the cases have also allowed me to engage different departments across SP. It made me realise that any issue faced in an organisation requires a synergistic approach, from working with colleagues handling core operations to corporate functions such as finance and communications. We can produce desired outcomes with strong teamwork.” Lydia and her colleagues have made significant inroads in moving the needle towards a more sustainable future. Her sustainability work portfolio includes managing potential investments in renewable energy projects, and collaborations with regional partners. In the process, she gained knowledge and insights that have strengthened her commitment to do her part for a greener economy.   On making her mark in a conventionally male-dominated industry, Lydia keeps her focus on “bringing value to the table”. “I am very grateful that there is no stereotyping in my organisation. We have several female management leaders at the helm and personally, I am inspired by my Chief Legal Officer who never fails to amaze me with her ability to juggle multiple hats and keep things under control. I’ve learnt the importance of being sharp in analysis and thought processes, and communicating effectively across all levels. Trust and respect will naturally follow.”   Lydia’s love for travelling and adventure has brought her to places such as Iceland, Morocco and Russia. “Travel widens one’s perspective like no other. It stimulates my mental and emotional well-being as I experience new cultures, meet new people and witness new landscapes!” Her wish, just like many of us, is to see the end of COVID-19 so that she can resume her travels and fuel her wanderlust!
