Media Release SP GROUP AND I-REC HELP CORPORATES ACHIEVE GREEN TARGETS SP’s digital REC platform facilitates greater access to green energy Singapore, 31 October 2019 – SP Group (SP) is the first authorised local issuer of International Renewable Energy Certificates (I-RECs) in Asia Pacific. This independent accreditation by the globally recognised International REC Standard Foundation (I-REC Standard) means consumers can be assured of the integrity of each REC transaction. SP has also enhanced its digital REC trading platform to provide a one-stop solution for buyers and sellers around the globe – regardless of size, business or location – to gain greater access to green energy. In 2018, more than 1,000,000 GWh of renewable energy certificates (RECs) were issued globally, amounting to more than 20 times of Singapore’s annual energy consumption. The challenge to achieving green targets Singapore has a target to increase solar penetration to 350 MWp by 2020 and to reach 2 GWp by 2030 1 . Companies have also set targets to consume renewable energy and reduce carbon emission. In urban places faced with limited land to produce energy from natural resources and inconsistent solar energy, corporates find it a challenge to access sufficient green energy supply. RECs as a solution RECs are a recognised way of achieving renewable energy targets and a credible means to report that the consumed energy comes from renewable energy sources. With each megawatt-hour of green energy produced, one REC is recorded and uniquely numbered and tracked. A buyer can purchase the REC and show proof that he or she consumed green energy. The latest example of using RECs is the sponsorship by SP Group of RECs matching the electricity consumed for the Singapore International Energy Week (SIEW) 2019. SP’s sponsorship means the electricity consumed at SIEW is matched with an equivalent amount of green energy produced. 1 Energy Market Authority of Singapore Media Release – The Future of Singapore’s Energy Story (29 October 2019) 1 I-REC accreditation provides security and integrity assurance SP, as an authorised I-REC local issuer, ensures that a vigorous and transparent attribute tracking system is in place and adherence to best practices. This avoids double counting, double certificate issuance and double attribute claiming. Jared Braslawsky, Secretary General of the International REC Standard Foundation, said: “Reliable information and robust tracking systems are key to ensuring the reliability and integrity of RECs around the world. The I-REC Standard empowers consumers to take responsibility not just for the energy they consumed but also for the origin of the energy consumed. With the support of SP Group, there is a neutral and unprejudiced market facilitator who can play a crucial role in strengthening consumers’ sustainability efforts.” One-stop platform provides ease and convenience SP’s digital REC platform, first introduced in 2018, was designed by its in-house digital engineers to digitally link up buyers and sellers of RECs, making it easier for the trading of RECs. However, sellers had to deal with multiple manual processes to enable the trading of RECs. The enhanced platform provides a seamless one-stop solution which automates the entire process of buying and selling RECs. Speaking at SP’s I-REC Forum in conjunction with the SIEW 2019, May Liew, Head of Sustainability & Open Innovation, SP Group, said: “SP is removing barriers so that big and small organisations can achieve their green targets seamlessly and securely. With our one-stop digital REC platform, they not only have the assurance that the electricity they consume comes from renewable sources, they can also buy and sell RECs without the hassle of dealing with multiple manual processes to issue and verify the RECs.” -Ends- 2 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

TAKING HEART SP Group donates S$1.35m to support 450 disadvantaged ITE students It will send students on work-study stints in power grids, sustainable energy, new tech. BY MEGAN CHEAH SINGAPORE utility group SP Group is donating S$1.35 million to support 450 engineering school students in the Institute of Technical Education (ITE) through the inaugural SP Group Engineering Study Awards. The funds will be disbursed monthly to the students, who come from low-income families, over the next 3 years, the group said Launched on Tuesday (Apr 12), the new awards will complement existing book prizes for ITE’s electrical engineering students offered by the group. The group is working with ITE to send students on work-study stints in areas such as power grids, sustainable energy, and new technologies. It also links students up with SP Group’s engineers, who serve as mentors. The group noted that more than 16 per cent of its 3,600 staff are ITE alumni. Among them, close to 60 per cent went on to pursue further education and attained diplomas or degrees. Stanley Huang, group chief executive officer (CEO) of SP Group, said the group is committed to encouraging youth to pursue their career aspirations regardless of their socio-economic background. “ITE has provided many of our technical officers and technicians a strong foundation to grow their engineering capabilities,” he added. ITE CEO Low Khah Gek said the study award will enable students with financial needs to take on fewer part-time jobs and Left and above: ITE students and SP Powergrid staff. The funds from the SP Group Engineering Study Awards will be disbursed monthly to 450 ITE students over the next 3 years. PHOTOS: SP GROUP focus on their education. One such award recipient is Jackie Lim, a first-year Nitec mechatronics and robotics student who works part-time at a supermarket to help with his family’s expenses. “I am happy to receive the study award, because it means I do not need to keep thinking about having to work more hours and can instead focus more time on school,” said Lim. For over 20 years, SP Group has awarded more than 450 education scholarships, sponsorships and book prizes, amounting to S$10 million, to students with a passion for engineering across all tertiary education institutions. megancheah@sph.com.sg

Free N95 masks in kits for every home BY ADRIAN LIM E VERY household here will receive three N95 face masks, as part of a nation-wide push to get individuals to think about being prepared for emergencies, such as haze crises and flu pandemics. The 3M brand foldable masks are packed in a “Stay Prepared” kit that will also contain instructions in four languages on how to put them on, and useful emergency contact numbers. A total of 1.2 million kits will be delivered to homes between today and next Monday. The initiative is led by Temasek Cares, a non-profit philantrophic arm under Temasek Holdings, in partnership with Singapore Power and Singapore Post. Temasek Cares will be pumping in $4 million from its $40 million war chest, called the Temasek Emergency Preparedness Fund, for the mask distribution programme. The fund was set up earlier this year to help Singaporeans prepare and deal with emergencies. Last month, a $1.5 million project to train 60 therapists to help children deal with traumatic situations, such as accidents, was also launched. Richard Magnus, chairman of Temasek Cares, said the kits will give households an “initial stock” of masks to encourage them to plan their own contingencies. “It’s a habit of mind we want to prompt... Last June, there was a severe haze that impacted Singapore... we need to be prepared,” said Mr Magnus. The Asean Specialised Meteorological Centre expects this year’s haze to be worse than last year’s. This is because of lower than usual rainfall expected from now till October in parts of the region and the El Nino weather pattern, which is linked to drought, said reports. Being prepared earlier will also prevent a repeat of last June, when people scrambled to stock up on face masks. An additional 17,000 kits will also be delivered to over 140 charity homes, and another 300,000 have been prepared on standby for needy families. Mary Abishagam, 57, a senior administrative assistant with Singapore Power, said she will be volunteering an extra three hours every day, on top of her regular work, to help pack the kits for delivery. “It’s going to be challenging, but we will manage... We are getting people prepared and not many people have thought of keeping masks in their homes,” she said cheerily. Members of the public who wish to get more information about the delivery of the kits can call a hotline, 1800-738-2000, from today until May 24, between 8am and 8pm daily. adrianl@sph.com.sg
