SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Mobile Generators: Powering Continuity RELIABILITY Mohamed Nasir bin Mohamed Ismail, Technical Officer, Electricity Operations (center) together with Ismet Imran bin Chuma'ing, Senior Technician, Electricity Operations (left) and Mohammad Najib bin Jalil, Technical Officer, Electricity Operations (right) from SP Group's Mobile Generator Unit. When an electrical glitch hit Kian Teck Avenue in Jurong last month, a team from SP Group’s Mobile Generator Unit was charged and ready to roll. In minutes, a mobile generator mounted on a 30-ft trailer left a facility in Pasir Panjang for the site of the incident. The generator carried some 2,000 litres of diesel, enough to power up a housing estate for around eight hours, and up to 40 metres of cable to hook up to a low-voltage (LV) board, which distributes electricity. “We need to always be prepared to provide temporary power,” says Mr Mohamed Nasir bin Mohamed Ismail, 42, a technical officer who is part of the unit. Readiness is key for the Mobile Generator Unit. This begins at 7.30am with a daily “warm up”, conducted by the 10 men on the morning shift. During the one-hour ritual, all the operational mobile generators – the larger ones mounted on fourteen 30-ft trailers, and the smaller ones on seven 20-ft lorries – are started and tested to ensure they are ready to be deployed. The team members also conduct cable insulation tests and checks on their toolboxes and personal protection gear. This enables them to act swiftly and safely, in the event of an electricity disruption. The men, who work on three shifts round the clock, are deployed by SP Group’s Electricity Service Centre in teams of three – a leader, an assistant, and a driver. Mr Nasir, the leader of his team, has been with SP for 21 years, joining right after he completed his National Service in 1998. He studied mechanical engineering at the ITE and plays the role of synchroniser, ensuring that the voltage and frequency of the mobile generator matches that of the grid network. Mr Nasir, who has both a Class 4 and Class 5 driving license, doubles up as a driver, and says navigating these massive vehicles is an exercise that requires both practice and courage. The trailer-mounted mobile generators cannot travel through tunnels, including those on expressways like the MCE, CTE or KPE. The 60km/h speed limit also keeps them in the slowest lanes most of the time. The trailer-mounted generators are part of a fleet of 22 vehicles of different sizes and capacities used for power restoration. “You need to know the quickest alternative route around traffic or restrictions. Outage in Ang Mo Kio and leaving from Pasir Panjang? Alexandra, Farrer, Adam, Braddell, then join the CTE after the tunnel,” Mr Nasir rattles off. The narrow roads in some estates and parked vehicles can also pose problems for the 13 metres by 2.6 metres by 4.3 metres trailers, and it is up to the two men with the driver to recce for a spot to hunker down – which must also be close enough to an electrical room to hook up. While Singapore enjoys one of the lowest occurrences of outages in the world, it is gratifying to be a part of a team that helps “get the lights back on" if supply is disrupted, Mr Nasir says. “We are usually greeted by frustrated faces when we arrive, so seeing them happy again makes us very happy,” he quipped. — 1 May 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing

BANKING & FINANCE Singtel, Wilmar, SP Group and Razer in green finance push on Earth Day � THU, APR 22, 2021 - 4:34 PM S PRIYASHINI � spriya@sph.com.sg SINGAPORE companies on Thursday committed to clean and green nancing projects, coinciding with the global observance of Earth Day. Singapore Telecommunications (Singtel), Wilmar International and SP Group made separate announcements indicating their moves to amp up the provision of green nancing and sustainability-linked loans. These loans aim to support and nance projects that are aligned with environmental, social and governance (ESG) standards and clean sectors. SINGTEL The telco's wholly-owned subsidiary launched its rst sustainability-linked revolving credit facility of S$750 million, the largest Singapore-dollar denominated sustainability-linked loan to date, the company said in an exchange ling on Thursday. This marks the group's foray into sustainable nancing under its new programme Olives, which is linked to sustainability targets. DBS, OCBC and UOB have teamed up to provide this credit facility. The three-year loan encompasses interest rate discounts pegged to pre-determined ESG targets in areas such as climate risk, carbon management and workplace health and safety metrics. The loan is guaranteed by Singtel and will be used for general corporate purposes. SP GROUP Singapore's national utility has launched a green nancing framework and obtained its maiden green loan facilities amounting to S$100 million from DBS, OCBC and UOB on a bilateral basis in a move that seeks to deepen the integration of sustainability into its nancing strategy. Under this framework, the company and its subsidiaries will issue green nancing instruments to nance or re nance eligible green projects along verticals such as clean transportation, energy e ciency, renewable energy and green buildings. In a joint press statement, the group highlighted that the framework enables investors and lenders to have greater visibility of the use of the proceeds and the environmental impact of the projects funded by the instruments handed out. WILMAR INTERNATIONAL The agri-business company announced the closure of a twoyear US$100 million sustainability-linked facility together with nancial services company Credit Agricole CIB. The company added that the margin of the facility will be dependent on Wilmar's performance of sustainability-linked key performance indicators (KPIs). Additionally, the facility incorporates a tiered discount mechanism where the achievement of each KPI is given a speci ed discount and the margin will be reduced by the aggregate of the discounts applicable for the KPI(s) achieved. Some of these KPIs include Wilmar's continued inclusion in the Dow Jones Sustainability Index (DJSI) Asia Paci c, achievements or improvements in benchmark rating by independent organisations and traceability targets. RAZER Hong Kong-listed gaming rm Razer also launched a US$50 million fund to invest in startups working in the environmental and sustainability space on Thursday. It looks to invest in seed and Series A funding rounds globally, ranging from US$100,000 to US$1 million.

SP GROUP AND GARDENS BY THE BAY PILOT ZERO-WASTE GASIFICATION SYSTEM System paves way for sustainable district solutions in Singapore Media Release Singapore, 6 June 2019 – SP Group (SP) and Gardens by the Bay announced plans to pilot a zerowaste solution at the Gardens. Using compact gasification technology to convert waste into thermal energy and biochar (carbonised biomass), the system could help to reduce carbon emissions by up to 20 per cent. The smart waste management system could enable sustainable zero-waste districts to be viable in Singapore, bringing the country closer towards a circular economy. At Ecosperity Week 2019, SP and Gardens by the Bay signed an agreement on the rollout of the system, supported by Temasek. The signing was witnessed by Minister for the Environment and Water Resources, Mr Masagos Zulkifli. Gasification is an alternative to incineration and it reduces waste to only five per cent of its original volume. There is also no need for the sorting of plastics from general or food waste. This addresses some of Singapore’s key waste disposal challenges. Without the need to transport waste to offsite incineration plants, the use of refuse trucks will also be reduced significantly. This will help to ease traffic conditions and further reduce carbon emissions. The pilot system can handle up to one tonne of waste per day and converts the waste into energy by-products as well as biochar for the Gardens. The main by-product is synthesis gas (syngas) that can be used for thermal heating. The biochar has been known to be used as a soil amendment in agriculture and horticulture, to condition the soil. Mr Jimmy Khoo, CEO, Singapore District Cooling, SP Group, said, “We are developing district solutions to help Singapore achieve its sustainability goals. This paves the way for decentralised waste management for other businesses and residential estates. We are pleased to work with Temasek and Gardens by the Bay towards a zero-waste green space for Singaporeans to enjoy.” Mr Felix Loh, CEO, Gardens by the Bay, said, “As a garden that values nature and sustainability, we have a responsibility towards finding innovative ways to protect our environment. Gardens by the Bay is uniquely placed to allow for the testing of such an onsite system because waste collected in the Gardens can be directly converted and repurposed into by-products, which can in turn be used in the Gardens.” Besides providing an experimentation site and supplying waste for the pilot, Gardens by the Bay will also be studying the usefulness and viability of biochar in improving local soil conditions. Waste generation in Singapore increased seven-fold over the past 40 years. In 2018, 7.7 million tonnes of solid waste was generated and this figure is projected to increase. Even with waste incineration, Singapore’s only landfill at Pulau Semakau will be full by 2035. Building new offshore landfill sites is also not sustainable in land-scarce Singapore.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Partnership with PUB in EMA’s Demand Response and Interruptible Load programmes RELIABILITY (from left) Stanley Huang, Group CEO, SP Group;S Harsha, Managing Director, Sustainable Energy Solutions, SP Group; Harry Seah, Deputy Chief Executive (Operations), PUB; and Goh Si Hou, Chief Executive, PUB, at the MOU signing ceremony. (Credit: PUB, Singapore’s National Water Agency) SP Group (SP) has partnered PUB to participate in EMA’s Demand Response (DR) and Interruptible Load (IL) programmes. PUB is the first government agency to participate in the programmes. PUB will voluntarily reduce its energy use or temporarily shift electricity usage during periods of peak usage or when supply from renewable energy sources is intermittent. This will help balance electricity demand and supply on the national power grid at critical times, while facilitating the integration of more renewables. For a start, PUB has identified the Marina Raw Water Pumping Station, located at Kallang Basin, as the first contributing facility. The pumping station is used to transfer raw water from Marina Reservoir to Upper Peirce Reservoir and there is flexibility to adjust operations when required to manage or reduce electricity usage. SP has been operating the Thermal Energy Storage system as part of its Marina Bay District Cooling operations since 2006 to improve the overall reliability and resilience of the network. In 2016, the team started developing process, control and data science capabilities to become an active participant in EMA’s demand-side management activities through the DR and IL programmes. In 2022, SP became a DR aggregator, which presented SP the unique opportunity to facilitate electricity load curtailment across multiple sites, and for other suitable companies. — 6 April 2023 TAGS RELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing
