Media Release Singapore Power Charity Golf Raised $363,800 For Needy Elderly $7 million channelled to Home Help Service through SP Heartware Fund Singapore, 27 August 2013 - As if being encumbered with the triple chronic dread disease of hypertension, hypolipidemia (high cholesterol) and diabetes is not enough, Madam Chin Fee Fee also suffers from spinal stenosis – a narrowing of the open spaces within her spine, which renders her almost immobile. Yet the 78-year-old, who lives alone, remains upbeat, thanks to a group of volunteers who deliver hot meals to her home everyday and ferry her to and from her home to her medical appointments. Madam Chin is a beneficiary of Dorcas Home Care Service - supported by the Singapore Power (SP) Heartware Fund. The Fund is dedicated to supporting Community Chest’s Home Help Service programmes, which help the needy elderly in our community age with hope and dignity by delivering critical care services to them in their homes. The SP Heartware Fund received a boost when Singapore Power, together with its business associates, raised more than $363,800 in support of the Singapore Power Charity Golf 2013 which will be held at the Singapore Island Country Club on Friday, 30 August 2013. The SP Charity Golf is Singapore Power’s key community outreach event for the year. All donations from the event are channelled to the SP Heartware Fund. Since the launch of the SP Heartware Fund in October 2005, Singapore Power has raised more than $7 million for Community Chest in support of seven Home Help Service programmes. Needy seniors who live alone and are unable to cater to their basic needs are the main beneficiaries of the programme which include daily meal deliveries, assistance with personal hygiene and laundry, and transport to medical appointments. The needy elderly remain the focus of Singapore Power’s community outreach endeavours in view of Singapore’s ageing demography. By 2030, it is projected that there will be 117,000 seniors who are semi-ambulant or non-ambulant, i.e. more than 2.5 times that of today1. A culture of giving and sharing is taking root at Singapore Power. Beyond collaborating with its partners to raise funds through events like the Charity Golf, Singapore Power also encourages its staff to do their part in reaching out to the community through various community outreach initiatives. One of these is the recently launched Nature Cares programme where Singapore Power staff took time off from work and spent quality time bonding with the residents of St John’s Home for Elderly Persons and students of Cedar Primary School, over nature-related activities such as making bottled gardens and visits to parks. These activities give much boost to the morale and emotional well-being of the elderly beneficiaries. Staff have also been involved in other charitable initiatives such as the JP Morgan Run, in aid of Operation Smile, which provides free surgeries to repair facial deformities for children around the globe. Said Mr Wong Kim Yin, Group Chief Executive Officer, Singapore Power: "The needy elderly have made valuable contributions to society. It is extremely heartening when we at Singapore Power and our business partners are united in the cause of giving our pioneer generation a lift for their basic daily activities, to provide medical assistance and to support their desire to live independently and with dignity." _________________________________ 1COS speech by Minister Gan Kim Yong on Ministerial Committee on Ageing Initiatives (7 Mar 12)   About the SP Heartware Fund The SP Heartware Fund was launched in October 2005 to help the needy elderly in the community lead better lives.

Madam Chin suffers from hypertension, hyperlipidemia (high cholesterol) and diabetes. She also has spinal stenosis – a narrowing of the open spaces within her spine, which puts pressure on her spinal cord and the nerves that travel through the spine. The condition causes her constant pain, numbness and muscle weakness. Her condition renders her home-bound most of the time, moving around her flat very slowly with the help of a walking aide. On the rare occasion when her health permits, she would travel on a wheelchair around her neighbourhood. Dorcas Home Care Service – supported by the SP Heartware Fund - has been providing Madam Chin with much needed assistance. Staff from Dorcas Home deliver hot meals to Madam Chin every day, and also provide transportation and escort her for medical appointments at the nearby Queenstown policlinic. In addition, staff and volunteers who help with the meal delivery make it a point to observe how Madam Chin is coping with the business of daily living and intervene where necessary. When Madam Chin’s mobility becomes increasingly laboured, volunteers would promptly inform staff of Dorcas Home who will then expedite a visit to the polyclinic. Said Madam Chin: “I am grateful for the kindness of volunteers who have helped me so much in my time of need.”

The Singapore Power employee felt it was his duty to help fix the problem. Inspired by his father’s passion for the job, Mr Muraliraj, 28, joined the same company three years ago. These days the father-and-son team work together to fix power Mr Tan Lih Chau (left), 40, and Mr Tan Lih Hong (right), 37, fete their father, Mr Tan San, 70, who scrimped to save for their education. ST PHOTO: DESMOND LIM trips. Mr Rajoo, an operation officer who has been with Singapore Power for 40 years, will notify his son, an executive engineer, who will then fix it. “He’s more like a friend to me,” said Mr Muraliraj of his 63-year-old father. “He showed me that if you enjoy what you’re doing, you won’t consider it working.” He is among at least four sons at the company who were inspired by their fathers’ careers. Technician Muhammad Hidayatullah, 24, was better known as “Ronan’s son” when he joined the company three months ago, encouraged by his father, Mr Ronan Othman, 52, also a technician. “My father would tell me about how they used to manually dig into the ground to lay the power cables,” said Mr Hidayatullah. “It was an eye-opener when I finally saw the large cables, 300mm in diameter, that he talked about.” Brothers Tan Lih Chau, 40, and Tan Lih Hong, 37, were inspired by their father’s work ethic and thrifty ways. Mr Tan San, 70, a civil engineer with resort operator Banyan Tree, often stayed away for six months to a year at a stretch, working on projects in places such as Phuket and the Maldives. The holiday resorts he built are physical reminders of the sacrifices he made to provide them with an education. “We didn’t come from a well-to-do family. My dad worked very hard,” said Mr Tan Lih Hong, deputy director of Singapore Power’s gas distribution department. His brother is a principal engineer in the cable tunnels team. He recalled that his father would not spend money on drinks when he went out for lunch. Instead, he would make do with plain water, just to save money for their education. Mr Tan added: “He always told us not to worry about our finances, just concentrate on our studies. If not for my dad, we would not be here today.” mellinjm@sph.com.sg More activities for fathers and children

The next best-performing city was Osaka, Japan, with an average of five minutes of supply disruption. Customers experienced an average of 0.85 minute of electricity interruption last year Source: SP GROUP STRAITS TIMES GRAPHICS Choo Yun Ting What happens when a power fault is reported? The course of action taken to restore the electricity supply depends on the severity and impact of the fault, says energy provider SP Group. In cases where the cause is a cable fault within the power grid, outages can mostly be resolved through remote or manual switching processes. But in instances of more lengthy outages, mobile generators are deployed as a temporary measure to restore electricity supply. CAUSES OF POWER OUTAGES Network Third party ACTION TAKEN 1 Equipment failure, human error affecting the power grid network Remote switching When a power fault is detected, this first course of action disconnects the affected equipment from the network and reconnects it to an alternative supply source. Remote switching is done at SP Group’s distribution control centre, the nerve centre of Singapore’s power grid, and is able to restore power supply in a matter of minutes. 2 Manual switching Manual switching requires officers on site to conduct the connecting/disconnecting process at the substation connected to where the fault has been reported. It is conducted when remote switching is unable to restore power supply. Power faults in low-voltage networks, such as damage to overground boxes that are used to transmit electricity to customers, are usually resolved through manual switching. 3 Mobile generators These generators are deployed when power faults are reported and are used as a temporary solution while the network issues are being resolved. The type of generator deployed varies depending on the area affected by the outage. For example, a 1MVA generator (right) is able to power four Housing Board blocks for up to eight hours. Approximately 100 households in one HDB block. 4 Cable jointing Cable jointing is conducted when remote switching and manual switching are unable to resolve the power fault and the mobile generators cannot access the substation where the fault has occurred. This process requires a longer time than remote switching or manual switching. BY THE NUMBERS Power restoration within one hour (past five years) 90% Number of substations More than 11,000 Damage to power cables, overground boxes by external parties Power restoration within two hours (past five years) 99% Length of cables that make up Singapore’s electricity grid 27,000km Faults on consumer's side Issues with electrical equipment on site Power supply Issues with the source of power supply, such as with powergenerating units The 500 kVA generator (left) can restore electricity supply to two HDB blocks for up to eight hours. Number of overground boxes More than 28,000 Number of mobile and portable generators (Eight 1MVA, two 800kVA, four 500kVA, four 50kVA, 34 four 20kVA, 12 6.5kVA) Source: SP GROUP PHOTOS: DESMOND WEE & SP GROUP STRAITS TIMES GRAPHICS Ten minutes. That is how long Mr Mohamed Nasir Mohamed Ismail, a technical officer with SP Group’s electricity operations, and his mobile generator unit team have to prepare before leaving their Pasir Panjang base when they are activated during a power failure. The 20-strong team operates in three-man groups, each comprising a leader, an assistant and a driver, around the clock. The driver of the 1MVA mobile generator, which is about three times as long as an average sedan car, has to work out the quickest and safest route to their destination – not an easy task, given that the trailers are not allowed to travel through tunnels. But there are some fixed routes that Mr Nasir, 42, who has been working at SP Group for 21 years, and his teammates have familiarised themselves with, he told The Straits Times during a visit to the company’s facility in Ayer Rajah. For example, to get from the depot in Pasir Panjang to a site in Ang Mo Kio, they drive from Alexandra Road to Braddell Road before merging onto the Central Expressway. “Human GPS (global positioning system),” Mr Nasir said, referring to how they decide on the best route to take with the large trailer. The mobile generators are activated as a stopgap measure whenever a power failure is reported, while technical officers are dispatched to the site to conduct manual switching to an alternative power supply, SP Group said. In two recent incidents of power failure, which occurred on Jan 26 and Feb 14 in Bright Hill and Carlton Hotel, respectively, the 1MVA mobile generators were activated but not used. Both incidents involved equipment failure that caused fires in substations. Last September, more than 140,000 residential and commercial customers across Singapore were affected by a blackout. It was later traced to the tripping of power-generating units of Sembcorp Cogen and Senoko Energy. However, in that incident, mobile generators were not activated. This was because the outage was caused by issues with the powergenerating units, and the mobile generators available would not have been sufficient to restore supply to affected areas, said SP Group’s director of electricity operations, Mr Cedric Lee, 43. “The fastest way to resolve the issue was to conduct remote switching once the generators were back up,” he added. Senior Minister of State for Trade and Industry Koh Poh Koon, in a Facebook post on Feb 16 after a visit to SP Group’s Kim Chuan substation following the Carlton Hotel incident, had written about some of the regular maintenance measures undertaken by SP Group to ensure the reliability of Singapore’s power supply. Mr Lee said one of those measures is the online condition-monitoring system that the energy provider uses for its high-voltage 400kV and 230kV switchgears. The system, introduced in 2005, monitors the network around the clock and allows for equipment to be calibrated online. In comparison, physical monitoring, which is conducted every six to nine months, measures only the voltage and equipment condition at the point in time when the checks are being conducted. The energy provider also uses a remote control system for the 6.6kV distribution network, which allows for power faults to be isolated remotely to restore supply. The system, which has been rolled out to 90 per cent of 4,450 substations, was introduced in 2014 and is slated for completion next year. “But in any power grid, any network, there is no 100 per cent,” Mr Lee said, adding that system faults are inevitable. Based on the system average interruption duration index – a reliability indicator for electric power utilities – in 2017, Singapore’s power system is ranked among the best in the world. Customers in Singapore experienced the lowest average of 0.19 of a minute of electricity interruption in 2017, compared with other major cities such as Tokyo and London. The next best-performing city was Osaka, Japan, with an average of five minutes of supply disruption. For Mr Nasir and his colleagues, ensuring the reliability of the power grid means that they are effectively on 24-hour standby, even after their eight-hour shifts have ended for the day, and some family outings have inevitably been interrupted over the years. On several occasions, Mr Nasir has received calls asking him to report back for work just as he was about to go out for dinner with his children. “It was frustrating initially (to be on standby), but it is worth it,” he said, referring to coming to the aid of people affected by a power failure. “It’s a satisfaction we get, seeing their frustrated faces turn to happy faces.” yuntingc@sph.com.sg Source: The Straits Times © Singapore Press Holdings Limited.

| TUESDAY, APRIL 19, 2022 | THE STRAITS TIMES | B1 SINGAPORE >98% LOCAL COVID-19 CASES SINCE MARCH 15 INFECTED BY BA.2 VARIANT | B5 Tampines to get cooling system by 2025 Ang Qing By the first half of 2025, Tampines will become the first town centre here to retrofit a centralised cooling system in a project that will slash the environmental cost of air-conditioning. It will also pave the way for more than 80 per cent of buildings in Singapore to follow suit. Yesterday, owners of seven buildings agreed to start work on SP Group’s first distributed district cooling network, with another slated to join in the future, said SP Group and investment company Temasek in a statement. District cooling technology involves generating chilled water in a centralised location, and then sending the water through a network to multiple buildings. It is more energy efficient as the system reaps the benefits of economies of scale. While air-conditioning was hailed by founding prime minister Lee Kuan Yew as Singapore’s secret to success in the tropics, its comfort comes at the price of up to half of a building’s energy consumption. The shared infrastructure from ENERGY SAVINGS continued on B2 How a district cooling system works District cooling system Imagine a giant air-conditioner that can cool an entire district of buildings, rather than just individual buildings, but one that is greener and more energy efficient. How does it work? Chilled water (4 deg C to 7 deg C) OFFICE BUILDINGS COOLING TOWERS RETAIL BUILDINGS Warmer water (12 deg C to 14 deg C) 1 CENTRAL COOLING PLANT Chilled water is generated in a central cooling plant. Carbon emissions Reduction of carbon emissions by 1,359 tonnes annually, equivalent to taking 1,236 cars off the road 5 Benefits of system 2 Energy transfer station COMMUNITY CENTRES 4 3 Thermal storage tank The warmer water is then circulated to the cooling plant, via the return pipes, to be chilled again. The whole process repeats. A closed-loop network of underground insulated pipes distributes the chilled water to each building. Thermal storage tanks are designed to store cold energy in the form of ice or chilled water. They help to regulate cooling demand and provide resilience. Not all district cooling system plants deploy thermal storage tanks. Energy savings Over 2,800,000 kilowatt hours annually, equivalent to the power consumption of more than 900 three-room HDB households for a year Energy transfer stations within each building circulate the cold energy from the network into the building’s air-conditioning system, which dehumidifies and cools the air. Cost saving Up to $50.8m of life-cycle economic benefits over 30 years Eight buildings in Tampines to be part of network The distributed cooling system will tap existing chiller plants in several buildings within the network to supply linked buildings with chilled water for their cooling needs.

They may also need to invest in more chillers than necessary as a buffer against potential increases in cooling needs. • Since the cooling demand of a building fluctuates throughout the day, the chiller in one building is unlikely to operate at its optimal efficiency. On-site cooling equipment, chillers and cooling towers need to operate round the clock regardless of energy demand. Sources: TEMASEK, SP GROUP STRAITS TIMES GRAPHICS
