SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Making the Right Connections RELIABILITY When Van Koh received a pre-owned computer at the age of 12 from his aunt, it promptly made its way to a neat pile of “treasure”. It heralded what would become both a passion and a career for young Van – and he eventually converted a nook in his family’s four-room flat into a “workshop” to house more such treasures. His enthusiasm would eventually win him an SP Group Nithiah Nandan Polytechnic Scholarship in 2015 to study electrical engineering at Ngee Ann Polytechnic. “I’ve always liked learning how things tick, and figuring out how to make them work even better,” says the 26-year-old, now the youngest cable jointer in SP Group’s Electricity Operations department. High voltage passion: Van (bottom) maintains transmission overground boxes such as the one above with his fellow cable jointer Mohammad Rosman B Abdul Wahab. As part of an 18-man team, Van maintains and repairs extra high voltage power cables that connect the transmission network, a key component of Singapore's grid. The team is also on 24-hour standby in case of any transmission network emergency situation. The transmission network transports electricity from the generation plants to our transmission substations across Singapore before the power is distributed to customers. Therefore, it is imperative to maintain a top-notch transmission network to prevent network disruptions.  But maintaining the cables and connecting them is hard work – a single cable can be as wide as a human palm and has a complex internal structure, and the length of a circuit can be up to 30 km. “These are large, high-voltage cables with many layers. It is hard work that is hands-on, and can easily take several days. But we need to make sure all the elements within the network function well to prevent an outage.” It takes a four-man crew, excluding a cable engineer who cuts off power supply so the men can work safely, to get the job done. And the men often have to get down into the trenches – literally – since most cables are underground. Hands on: Getting down to business doing cable jointing in the trench with his colleagues Krishnasamy Shanmuguraj (left) and Sanjay Kumar (right). “You get very used to working in confined spaces,” says Van. But working in close quarters forges tight bonds and means Van – surrounded by men who have been in the job for 30 to 40 years – has no shortage of mentors. “They are like my uncles. They explain things I don’t understand but also give me life lessons when we makan (Malay for eat),” he says. In fact, it was at the urging of these “uncles” that, two years into the job, Van enrolled for a degree course in electrical and electronic engineering at the Nanyang Technology University. He graduates in 2021, having chosen to study at night and keep his day-job. “At school, you learn a lot of theory. Work gives me the hands-on exposure you cannot find in books. That’s really important to me… and I enjoy that,” he says. Even in his free time, the tinkering continues in his home “workshop”. Some of the inspired creations that emerged from that space include a fitness robot instructor for the elderly for his final-year polytechnic project and parts for his remote control planes. It was also there that, with his colleagues, he developed a prototype device that will improve safety and productivity in his line of work.  In January this year, the prototype won first prize in SP’s intrapreneurship competition. “When I look at all the work that goes into maintaining the network, and how my colleagues really put their hearts into the job, it inspires me to want to make things better, and to keep getting better at what I do.” The winning team: Van (centre) with his colleagues were the winning team in SP’s intrapreneurship competition held earlier this year. — 28 August 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

MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 JULY TO 30 SEPTEMBER 2022 Singapore, 30 June 2022 – For the period from 1 July to 30 September 2022, electricity tariff (before 7% GST) will increase by an average of 8.1% or 2.21 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost driven by rising 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 27.94 to 30.17 cents per kWh for 1 July to 30 September 2022. The average monthly electricity bill for families living in HDB four-room flats will increase by $8.25 (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. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) 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. b) Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. c) 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. d) 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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation The Doctor Is In: Grid Health Checks Prevent Issues RELIABILITY Reading the “pulse” of network equipment, Senior Engineer Dr Lai Kai Xian can tell whether insulation material within the equipment may be breaking down. Like any good physician, Dr Lai Kai Xian is skilled in being able to look, listen and feel. The key difference is that his patient is Singapore’s electricity network, and he diagnoses the grid’s health conditions and fixes these even before they become problems. The 35-year-old electrical engineer is one of eight specialists in the SP Group’s Condition Monitoring team who keeps a close eye on the 11,000 substations and over 28,000km of cables that make up the grid. They are supported by 44 technical officers and technicians who conduct regular health screenings of all equipment on the network, and recommend deeper investigations or treatment when necessary.  Condition Monitoring Senior Engineer Dr Lai Kai Xian uses devices that require various senses – hearing, sight and touch – to assess equipment health, much like a medical doctor. Technicians take the network’s temperature using thermal guns, and listen for abnormal sounds using sensors coupled with headsets that make high frequency sounds audible. Special probes listen for the “pulse” of the equipment, and normal sounds need to be distinguished from ones that could indicate a potential problem. Sounds called transient earth voltage signals could point to internal voids in liquid, air or solid insulation material that are wrapped around cables. These kinds of “partial discharge” summon more varied equipment to pinpoint the source of an abnormality, and allow for early intervention. “These markers tell you where more investigation is needed or where problems could potentially lie so they can be solved before they get any bigger,” explains Dr Lai. He had focused his PhD studies on condition monitoring, and thanks his parents for the opportunity to have done so in Australia. SeniorEngineer Dr Lai Kai Xian (left) with his parents (right) at the 2010 University of New South Wales graduation ceremony. He was awarded a Doctor of Philosophy in Electrical Engineering. Like any emergency room, the most critical cases are attended to first, and more tests can be ordered to make a more accurate diagnosis. It can sometimes make for an intense work day, he concedes. But until his first child arrives in October, the grid is his baby – indeed his personal hobbies include reading technical articles about power systems and new technologies. Condition monitoring affords the grid an additional layer of insurance over scheduled maintenance, making it even more reliable, says Dr Lai. According to Dr Lai, an average of 70 potential problems have been avoided each year over the last five years. And unlike scheduled maintenance work which may require a piece of equipment to be taken out of service to be checked, repaired, or replaced, this pre-emptive approach is non-invasive, requiring no shutdowns. In the long run, keeping the health of a piece of equipment in check also means it lasts longer, he says. More companies are now catching on to these benefits, says Dr Lai, adding that he had trouble finding a job specifically in condition monitoring until he joined SP, a big believer in “preventive medicine”. Online monitoring is also continuously leveraged by SP for the larger 400kV and 230kV substations that make up Singapore’s transmission network, with sensors transmitting real-time data to Dr Lai’s lab. New technologies that can make the grid more robust are also regularly assessed, adds Dr Lai, also a “doctor-on-call” for casual queries from other departments, thanks to friendships forged with colleagues through weekly badminton sessions. Getting to the root of the problem is one of the things he relishes most about his role in SP’s network reliability, especially since diagnosis can be as much of an art as a science, and prompts spirited debates. “You need to be able to look beyond the obvious with data. Every single case is different, requiring both tools and thinking. That is the challenge that I love.” — 13 June 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

The electricity tariff consists of the following four components: a) 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. b) Network costs (paid to SP PowerAssets): This fee is reviewed annually. This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Services): This fee is reviewed annually. This is to recover the costs of billing and meter reading, data management, retail market systems as well as for market development initiatives. d) 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.
