Advisory COVID-19: SUSPENSION OF MANUAL READING OF UTILITIES METERS Singapore, 7 April 2020 – While you stay home, SP Group will continue to provide essential services such as operating the national power grid and delivering electricity and gas supply to you. Our officers also continue to be on standby 24/7 to attend to any electricity/gas supply disruption. To protect you and our staff, our meter readers will not be visiting your premises to check your electricity, water and gas meters to record your monthly utilities consumption during the Circuit Breaker period, in line with safe distancing measures outlined by the Singapore government. The earliest appointment to close a utilities account will be available from 2 June onwards. We advise all customers to minimise scheduling appointments to open a utilities account during this period. For those without advanced electricity meters, your April and May utilities consumption will be based on an estimated amount and the difference will be adjusted in your subsequent bills.

Taking Heart Deloitte donates $30,000 to HCA Hospice Care SINGAPORE’s largest home hospice provider, HCA Hospice Care, has received a donation of $30,000 from Deloitte Singapore. The funds were raised through a two-month internal campaign leading up to last Thursday’s JP Morgan Corporate Challenge, in which 892 runners registered under Deloitte. For every $1,000 raised for HCA Hospice Care, a staff member ran the race in a special costume – like the three little pigs and the big bad wolf. The $30,000 will go to HCA’s Star PALS programme, which provides home palliative care for children under the age of 19. Under the initiative, HCA’s teams visit these children’s homes to care for them and their families, both medically and emotionally. Separately, Deloitte’s participation also contributed $53,520 to the JP Morgan Corporate Challenge’s official beneficiary, Operation Smile. Million-dollar S’pore Power boost for Community Chest IN 2013, Singapore Power raised $1.05 million for Community Chest through the company’s Heartware Fund. The money will go towards Community Chest’s home help service programmes, which provide a range of practical assistance efforts for the elderly, such as the delivery of warm meals and transportation of elderly beneficiaries to hospitals for medical appointments. Contributions to the Heartware Fund are raised through donations from Singapore Power staff, business partners and the public. Singapore Power matches its staff donations to the fund dollar for dollar. Recycling efforts raise vouchers for needy students FOR the students who participated in the Recycling Helps @ South East campaign, their recycling efforts weren’t just good for the environment; they were also instrumental in raising funds for the needy. The initiative was jointly launched by NTUC FairPrice Foundation and South East Community Development Council. For every 5kg of recyclables collected by the students, FairPrice Foundation donated a set of $25 in FairPrice vouchers to a student from a less privileged family studying in schools within South East District. Through the efforts of 13 participating schools, over 2,000kg of used plastic bottles, paper and cans were collected for the cause. As a result, a total of $10,000 worth of vouchers were raised, benefiting 400 students from less privileged families.

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 April to 30 June 2022 Singapore, 31 March 2022 – For the period from 1 April to 30 June 2022, electricity tariff (before 7% GST) will increase by an average of 9.9% or 2.49 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost arising from significantly higher global gas and oil prices exacerbated by the conflict in Ukraine. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff. For households, the electricity tariff (before 7% GST) will increase from 25.44 to 27.94 cents per kWh for 1 April to 30 June 2022. The average monthly electricity bill for families living in HDB four-room flats will increase by $8.73 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic consumers). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The tariffs shown in Appendix 2 have been approved by EMA.   Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.   Q2 2022 TARIFF (before 7% GST) Appendix 2 ELECTRICITY TARIFFS FROM 1 APRIL 2022 Appendix 3 AVERAGE MONTHLY ELECTRICITY BILLS OF DOMESTIC CUSTOMERS TARIFF WEF 1 APRIL 2022 (before 7% GST)
