Media Release World's Largest Underground District Cooling Network At Marina Bay Saves More Than 40 Per Cent In Energy For Customers National Development Minister commissions Singapore District Cooling’s district cooling network, with Marina One signing customer contract today Singapore, 3 March 2016 – Singapore District Cooling (SDC), a subsidiary of Singapore Power (SP), formally commissioned its plant operations with the completion of a major expansion project, making it the world’s largest underground district cooling network. SDC serves key buildings in the Marina Bay financial district, including the Marina Bay Sands Integrated Resort, Marina Bay Financial Centre and Gardens By The Bay and is set to welcome new customers in the district. Chilled water generated by SDC is used for air conditioning. Customers enjoy the efficiency and energy savings of more than 40 per cent. This is achieved by leveraging economies of scale, optimising asset efficiency and upholding operational excellence. SDC’s underground centralised system eliminates the space requirements and upfront costs for customers’ own on-site chillers and roof-top spaces for cooling towers. At the event officiated by National Development Minister Lawrence Wong, SDC signed a new supply agreement with the mixed-use Marina One development at Marina South. Mr Ng Lang, CEO of Urban Redevelopment Authority, said, “Developing a centralised district cooling network to serve the Marina Bay precinct is a bold idea many years in the making. Today, we reap the benefits from early planning and thoughtful design, from freeing up space and saving costs to reducing carbon emissions. We are delighted to have worked with Singapore Power and many other partners to realise this vision for a vibrant and sustainable Marina Bay, one that is supported by world-class infrastructure.” Singapore Power’s Group CEO, Mr Wong Kim Yin, said, “SDC provides an efficient, reliable and sustainable solution that translates to significant energy savings for customers. Through SDC, Singapore has another world-class solution that can contribute to meeting the world’s need for a sustainable future.” Asia Square, one of SDC’s existing customers, has reaped environmental benefits and cost savings from SDC’s operations. Mr Philip Chan, Asia Square’s Sustainability Manager said: “As one of Singapore's finest developments in the heart of the city, environmental sustainability is an important feature for Asia Square. With Singapore District Cooling's energy-efficient cooling system, we are very happy with both the energy and cost savings that we have been able to achieve.” ###   About Singapore Power Singapore Power Group (SP) is a leading energy utility group in the Asia Pacific.

NKF hargai tujuh firma gajikan pesakit ginjal Majikan tawar masa kerja fleksibel agar pesakit dapat jalani rawatan �NUR DHUHA ESOOF nurdhuha@sph.com.sg TUJUH syarikat diberi penghargaan oleh Yayasan Buah Pinggang Kebangsaan (NKF) semalam kerana mengambil atau mengekalkan pesakit ginjal sebagai pekerja mereka. Syarikat itu – Kentucky Fried Chicken Management, McDonald’s Singapore, SIA Engineering Company, Singapore Power, S.K. Rosenbauer, UTC Aerospace Systems dan Wing Tai Holdings – diiktiraf kerana menyokong pesakit ginjal dengan menawarkan masa kerja fleksibel agar pesakit dapat menjalani rawatan yang diperlukan. Mereka menerima Anugerah Majikan Luar Biasa daripada tetamu terhormat, Menteri Tenaga Manusia, Encik Tan Chuan-Jin, dalam acara yang diadakan di Pusat NKF di Kim Keat Road itu. Sembilan Anugerah Keberanian turut disampaikan pada majlis penyampaian tersebut kepada pesakit ginjal yang terus aktif dan memberi sumbangan kepada tempat kerja masing-masing walaupun mempunyai masalah kesihatan. Tiga daripada penerima anugerah itu ialah Encik Johari Marzuki, 54 tahun; Encik Mohamed Hairi Bahari, 53 tahun; dan Encik Muhammad Aliwara, 49 tahun. NKF berkata lebih 700 pesakitnya mempunyai pekerjaan sepenuh atau separuh masa. Mereka perlu diberi masa menjalani dialisis tiga kali seminggu, dengan setiap sesi memakan masa sehingga empat jam. Menurut Encik Johari, yang telah 39 tahun berkhidmat bersama Singapore Power, majikannya menawarkan susunan kerja fleksibel bagi memberinya masa menjalani dialisis. Namun, pegawai teknikal kanan yang mengalami penyakit ginjal sejak 23 tahun lalu itu memilih menjalani rawatan pada sebelah malam kerana tidak mahu mengganggu operasi di tempat kerjanya. “Saya kerja dari 8 pagi hingga 5 petang. Kemudian saya ke pusat dialisis untuk menjalani rawatan dari 6.30 petang hingga 11 malam. Memang penatlah tapi dah jadi rutin hidup saya sekarang,” kata Encik Johari yang merupakan satu-satunya pesakit ginjal di Singapore Power buat masa ini. Pengarah Pengurusan syarikat itu, Encik Peter Leong, berkata pihaknya gembira melihat mutu kerja Encik Johari tidak terjejas walaupun beliau perlu kerap menjalani dialisis. Semasa ditemui media pada hujung acara, Encik Tan berkata beliau berharap syarikat dapat memberi penekanan kepada kesihatan di tempat kerja dan tidak hanya kepada keselamatan pekerja. “Jika syarikat memberi tumpuan kepada kesihatan menyeluruh pekerja mereka, ia akan membawa perbezaan ketara,” kata Encik Tan. Acara semalam turut meraikan ulang tahun pertama Program Sokongan Pesakit NKF yang menyediakan sokongan dan kaunseling kepada pesakit ginjal. Seramai 129 penyokong pesakit menyertai program tersebut sejak ia diperkenalkan dan mereka telah membantu 780 pesakit sejauh ini.

B6 HOME FRIDAY, NOVEMBER 22, 2013 FRIDAY, NOVEMBER 22, 2013 HOME B7 Like arteries and veins that keep the body alive with a constant flow of blood, close to 26,000km of cables, more than 3,240km of gas pipelines and a 3,000-strong team of people work around the clock to keep Singapore’s lights on and air cool. Arti Mulchand speaks to the unsung heroes. POWER TRIP Lighting up Marina Bay Getting power to the people IN 2004, when Mr Peter Leong oversaw the engineering division at Premas International, which provides property management services, Singapore was hit by one of its worst blackouts in history. Piped gas supply from Indonesia to Singapore’s power stations was disrupted by a technical fault and most turbines were unable to switch to the backup source of fuel. It caused a two-hour outage affecting more than 300,000 homes. In one home in Jurong, a man had a heart attack and needed to get to a hospital. The lifts did not work. At the time, Premas managed the Jurong Town Council, to which Mr Leong provided engineering support. “I had to send our contractor up to carry him down. I saw how the residents were affected. Failure can be very serious and I know how important continuity is. I remember that even now,” recalled the 57-year-old, who joined Singapore Power (SP) PowerGrid as general manager about five years ago. That image remains with him, and has served as a constant reminder in his current role as managing director of SP PowerGrid – he has to ensure “the lights are always on” for the company’s 1.4 million customers. “Singapore is like a copper mine. There is 26,000km of copper underground because everything needs power. Just like blood needs to flow to every part of the body, electricity needs to flow to every corner of Singapore. And like the human heart, we cannot afford to fail, so we do everything we can and put every effort into ensuring nothing goes wrong.” The three main areas Singapore Power covers are: planning and strategy, that is, planning ahead for energy needs; network development, that is, building the transmission and distribution network; and network management, that is, operating and maintaining network equipment. “The team works 24/7 to ensure the health of the system. We A SERIES BROUGHT TO YOU BY Building a more resilient grid THE power grid of the future could include a large number of distributed renewable generation sources such as solar photovoltaics, energy storage facilities and energy management systems. It is also expected to be flexible and scalable, such that fluctuations in energy demand or supply will not affect the grid’s stability and reliability. A team from the National University of Singapore, headed by Associate Professor Dipti Srinivasan, is working with SP PowerGrid to look into “dynamic optimisation and energy management for smart grids”. It hopes to develop a set of computational tools that will, among other things, automatically diagnose faults so outages can be handled quickly. respond immediately to any system distress,” Mr Leong said. Temperatures of transformers are taken, insulating oil is checked, and other parameters are continuously measured – whether online or off – to ensure that Mr Peter Leong, 57, managing director of SP PowerGrid, says that energy demand in Singapore has increased dramatically between the pre-war period and now. PHOTO: LIM YAOHUI FOR THE STRAITS TIMES the power paramedics can be sent in for swift and often pre-emptive responses. Exercises are conducted for everything from network management to billing, so that if anything goes wrong, everyone knows what to do. In the last 20 years, Singapore has achieved one of the most reliable grids in the world – the average amount of outage time has gone from 27.44 minutes per person a year two decades ago, to less than half a minute now. But just like Singapore has evolved, so must the power superhighways. Mr Leong says that energy demand has increased dramatically between the pre-war period and now. Power is pumped through some 26,000km of cables to more than 10,000 transmission and distribution substations that convert electricity into the necessary voltages for various uses. “As power demand grows, it becomes more efficient to push through power with higher-voltage cables. It is not unlike Singapore’s highways. Where two lanes used to do the job, we now have the Marina Coastal Expressway, which is 10 lanes wide. As energy intensity grows, we need a bigger highway,” said Mr Leong. The North-South and East-West Electricity Cable Tunnel Project is part of that expansion. Its two 60m-deep tunnels will span 35km way below the MRT and even the sewerage system and, when completed in 2018, will reinforce Singapore’s power grid as one of the most reliable in the world, said Mr Leong. The company has been looking into how new technologies and energy sources, such as solar photovoltaic power, could impact the grid. As Mr Leong listed some of the major infrastructural projects in store for the nation – Changi Airport’s Terminal 5, Project Jewel at Changi Airport, the redevelopment of the southern waterfront and new container ports at Tuas – his eyes lighted up. “We have to plan now for tomorrow,” he said with a smile. Mr Leong, who studied electrical engineering at RMIT University in Australia and did his master’s at the National University of Singapore, began his career at the then-Singapore Institute of Standards and Industrial Research, which eventually merged with the National Productivity Board to become Spring Singapore. There, he spent 18 years with safety on his mind, operating the nation’s test lab for equipment and accessories that connected to the electricity network, then regulated by PUB, the national water agency. He did product testing and also participated in investigations into electrical deaths. When he moved on to Premas, he oversaw the maintenance and operation of equipment such as chillers, lifts and switchboards in commercial buildings and techno parks, and several town councils. But it is at Singapore Power that he has found a “better sense of purpose”, he said. “I love being able to look at how to do things differently, and I can never say that my job is done. This is a journey without a finish line.” Mr Thiam Chiong Seng helped build the Marina South substation, which powers Marina Bay Sands and Gardens by the Bay. ST PHOTO: NEO XIAOBIN Senior engineer Chu Xiao En (left) at SP PowerGrid’s Emergency Operations Centre. PHOTO: LIM YAOHUI FOR THE STRAITS TIMES MORE THAN DRAWING LINES ASK senior engineer Chu Xiao En what the biggest misconception about her job is and she will tell you it is this: “People think that planners only draw lines.” The 27-year-old works in Singapore Power’s planning and strategy division, which plans for Singapore’s electrical infrastructural needs five, 10 and even 20 years down the road. They include the need for new substations, and the renewal or decommissioning of old ones. “While the end result of a plan and review might be a line connecting two substations, a lot of analysis goes into exploring every possible option and anticipating all kinds of contingencies,” she said. The 15-strong team she belongs to gathers input from customers along Singapore Power’s transmission and distribution grid, and looks at the growth and development plans for the country, said Ms Chu, who oversees network planning for Singapore’s western region. She covers areas WHEN Mr Thiam Chiong Seng drives along the East Coast Parkway and past the Marina Bay area, it is rarely without a smile on his face. The 47-year-old engineer is the director of network development at Singapore Power (SP), where he has worked for 16 years doing high-voltage equipment installations, including at the Marina South substation. That means keeping the lights on in iconic buildings that include Marina Bay Sands, the Marina Bay Financial Centre and Gardens by the Bay. “With Marina Bay, I know that we are literally powering it. You can see and feel the impact,” he said. “That’s why it’s very exciting being in the energy business. You’re not dealing with tiny electronics. What we build is so huge so you feel a real sense of satisfaction when you see a job completed.” SP’s network development engineers develop and build the infrastructure that ensures continuous and reliable power supply to households, as well as industrial and commercial buildings. This includes forging the fit between network demand and supply, conducting simulations and doing tests and checks on equipment before it is used. “We don’t want a situation in such as Choa Chu Kang, Jurong, Woodlands and Ayer Rajah. Part of the job includes carrying out simulation studies, planning cable routes and substation sites, and figuring out how to get the best possible network at the lowest cost. Each year, her department submits an updated 10-year plan to the Energy Market Authority (EMA), which takes into account developments and changes. “The EMA works top down and we work bottom up to forecast the national energy demand,” she explained, adding that based on the latest estimates, energy demand in Singapore could grow between 2.2 per cent and 3.7 per cent each year between this year and 2023. It is that kind of work that appeals to the self-confessed applied mathematics and physics fan. “I have always been a rational and logical person so that’s what attracted me to engineering. I like that one plus one will always be which we turn the equipment on and you suddenly see ‘fireworks’. We have our biggest fireworks display on National Day and we’d like to keep it that way,” Mr Thiam said with a laugh. What makes the Marina South substation unique is that it is Singapore’s first substation that can receive bulk energy transmissions at 230 kilovolts (kV) from the power generation companies and then convert it to 22kV, which is the voltage at which some consumers can use it. Usually, power has to be converted to 66kV before being reconverted to 22kV or lower voltages, but new equipment allows it to bypass that intermediate stage. That means saving on space and equipment cost. The current capacity of the substation is 300 megavolt amperes (MVA) – meaning it can power up an area up to twice the size of Ang Mo Kio Town. “But we have also future-proofed it so it can deal with the area’s expansion,” he explained, adding that the substation is capable of servicing the area’s needs for at least the next decade. The substation also has three sets of 230kV cables to create a situation of “double redundancy”, so even if one set is knocked out, the other two function as two,” said the Singapore Power scholar who did her degree in electrical engineering at Imperial College and her master’s at Stanford University. She joined Singapore Power in 2009. The job has multiple challenges. For instance, her department is looking into the renewal of a lot of electrical infrastructure that was created in the 1980s, but there are limitations on what can be done. “Most of the renewals are done in mature estates, so you’re working with a live network. You need to have a step-by-step contingency plan for anything that might go wrong,” she explained. The four years that Ms Chu has been at Singapore Power have included a three-month stint at the company’s Melbourne-based subsidiary Jemena, and eight months in Network Management, a department tasked with ensuring that power supply to customers does not get disrupted. She worked on, for instance, the diversion of power cables that Planning for the next generation back-up, keeping the lights on. Mr Thiam got involved in the Marina South project in 2000, when his team helped outline the technical requirements for transmitting power through South-east Asia’s first Common Services Tunnel, which was being built by the Urban Redevelopment Authority at the time. Those tunnels, which sit between 2.5m and 20m underground, deliver everything from electricity to chilled water and telecommunication cables. “The Government realised the CBD (Central Business District) had to be expanded, and we were able to support them in the development,” said Mr Thiam, who oversees a department of 18, including six engineers. Mr Thiam, who studied electrical and electronic engineering at Nanyang Technological University, started out in an industrial air-conditioning company before moving to an SP subcontractor doing maintenance work on 230kV transformers. He was so impressed with Singapore Power that he ended up applying for a job. He has not looked back since. What he is especially proud of is that other countries look to Singapore for the types and technical specifications of equipment used and even quality control processes. But communicating this information can be harder than one can imagine. “In China, it would be rude to speak English, but try finding the Chinese word for cross-linked polyethylene (XLPE) or polypropylene laminated paper (PPLP). Chinese is not our native language for technical terms,” he exclaimed with a laugh, referring to the types of insulation materials used in cables. His overseas exposure has also been eye-opening, not least because of the much higher tolerance level other countries have for disruptive electrical and road works. “In China and India, they understand that electrical cabling is for the good of the country. Here? We have to work at night or traffic would be obstructed, and we can work only a limited number of hours at night because residents complain about the noise,” he said, shaking his head. During the Marina South substation project, for instance, one 900m stretch of road between Anson Road and Cecil Street took almost two years to complete because work could be done only between 8pm and 4am and the noisier work had to be finished by 10pm. “In other countries, they would just block off the road and finish it up in just months.” had been laid under Upper Bukit Timah Road to make way for the construction of Downtown Line 2, which is due to be completed in 2016. “I never realised how much went into the planning of an MRT line. There is a lot of preparatory work that has to be done alongside other utility providers. I am now a lot more tolerant of road works,” said Ms Chu, whose husband is also an electrical engineer in the power sector. The time spent in Network Management made her an unlikely sympathiser when a fire broke out at SingTel’s Bukit Panjang facility in October, disrupting a range of services across the island, including her pay TV services at home. She was part of a team that, following a fault that tripped a circuit in Woodlands in 2009, had to walk along roads that had cables under them, armed with cable fault detectors and special headphones to identity the problem segment. It was about a day and a half before the segment was isolated, and only then could contractors proceed to dig up the road, find the fault and fix it. She said: “While the public was asking why there were no back-ups during the SingTel incident, I felt appreciative of what they were trying to do to restore the network. When these things happen, you are really trying your best to get things back up. I understand how challenging that can be.” And while being a planner also means gratification is much delayed, since most of the projects she has had a hand in planning have yet to become a reality, it makes the job no less fulfilling. “We get to be involved first-hand in nation-building. And I appreciate that the good performance of our network today is the result of the work of some of my mentors and the planners that have come before me. “Now, we’re planning for the next generation.” ENSURING SMOOTH OPERATIONS All fired up about keeping businesses cool SINGAPORE District Cooling’s (SDC) senior engineering officer for safety Ariff Shah Mohd proudly declares that in his seven years with the plant, there has not been a single serious accident. The plant, which spans 19,000 sq m, supplies the chilled water that keeps many buildings in the Marina Bay financial district cool. Among his responsibilities: to ensure compliance with safety measures and equipment, and make sure that all the permits for machinery are in order. “I have to cultivate a culture of safety among the staff as well as our contractors, and ensure that the plant has reliability and efficiency and operates safely. It can be tricky, and you have to be alert,” said the 39-year-old, who holds a position more often held by someone who is trained in engineering. Mr Ariff, an Institute of Technical Education graduate who studied mechanical and electrical drafting and design, toyed with the idea of becoming a policeman before ending up in IT support. Eventually, he learnt the ropes as an operations technician at a petrochemical plant on Jurong Island. That led him to a similar position at the SDC plant, which began operations in 2006. SDC is a joint venture between Singapore Power and Dalkia. After four years, he was given the opportunity to pursue a oneyear specialist diploma in workplace safety and health at Singapore Polytechnic in 2009, after which he was promoted to engineering officer for safety and projects. This year, he became senior engineering officer for safety. Today, he oversees all of the plant’s safety matters, including safety precautions that are in place, risk assessment, safety compliance and training. He is also the secretary of the plant’s 10-man safety committee, which meets once a month. This father of two is so passionate about safety that, this week, his team held its first SDC Safety Day. Some 70 spouses and children of SDC’s staff had a first-hand look at how the plant works and a lesson on why safety matters. Safety Day will now be an annual affair. Similarly, Mr Wong Toon Soon, the operations manager of Keppel District Heating and Cooling Systems (DHCS), started out in construction, doing electrical installations. Mr Wong, who is now 51 and also a father of two, became an electrical foreman after completing a full-time Industrial Technician Certificate course at Singapore Technical Institute. Mr Wong, who received his diploma in electrical engineering from Singapore Polytechnic in Neither Keppel DHCS operations manager Wong Toon Soon (above) nor Singapore District Cooling senior engineering officer for safety Ariff Shah Mohd (right) started their careers in the district cooling field, but both men now power vital aspects of their plants which provide cooling services in various parts of Singapore. ST PHOTOS: CAROLINE CHIA, NEO XIAOBIN 1991, was also keenly interested in energy efficiency, which was a buzzword in the late 1990s. He was introduced to the brand-new sector of district cooling when his company became involved in the construction of the Keppel DHCS plant in Changi Business Park, Singapore’s first district cooling system, in 1998. When completed, it would provide cooling services to businesses in the area, including commercial, banking, biomedical and wafer fabrication customers. Fascinated, he applied for a position as senior control engineer in 2003. He said: “During the construction phase, I realised they were using the latest energy-efficient technologies and I was excited at the prospect of learning more. This was my opportunity.” Just three years later, he was promoted to operations manager of all three of Keppel’s DHCS facilities. Keppel is the only other provider of district cooling services here, and services 18 customers in Changi Business Park and 18 at Biopolis. It also provides district cooling at Woodlands Wafer Fab Park. Mr Wong, who also has specialist diplomas in energy efficiency management and security networking, ensures that the plants run smoothly, and works closely with Keppel’s customers to help them maximise their efficiency gains. He was involved in setting up a DHCS plant in the Sino-Singapore Tianjin Eco-City in 2010, where he oversaw everything from its construction all the way to the time the chilled water started pumping. It has been up and running since August. At the moment, Mr Wong is planning to refresh the 13-year-old DHCS plant in Changi – Keppel’s oldest DHCS facility – with new and more efficient chiller equipment planned for next year. Keppel, which is looking into new sites for DHCS facilities, most recently secured the contract to provide district cooling to Mediapolis from the second quarter of 2015. Mr Wong is most encouraged by the growing footprint of district cooling, especially since building owners and tenants have much to benefit from this, both in terms of lower investment costs and energy savings. In the longer term, it also means having a smaller carbon footprint. “It is better for business, and better for the planet as well,” he concluded. CHILLING UNDERGROUND The world’s largest district cooling plant ALL the action at what is arguably the world’s largest district cooling plant by capacity is well hidden from public view. The plant is located five floors – about 25m – underground. The only evidence of the plant’s existence is a cleverly concealed cooling tower, which pops up above the ground facing Marina Bay Sands’ hotel building. A curtain of metal plates that allow exhaust heat to escape the tower shimmers in the sunlight, and a strategically placed water feature masks the sound of the water that flows from it. Even access to the plant, which produces 600 tonnes of chilled water per hour, is like a scene out of Alice in Wonderland – there is no signage, only a small door located at the end of the Double Helix Bridge. Stairs and a lift transport the plant’s 52 employees deeper underground. Chilled water is one of several utilities continuously pumped through a network of common services tunnels to 14 customers in the area, including Marina Bay Sands, the Marina Bay Financial Centre and One Raffles Quay. District cooling is an energy-efficient and cost-effective method to provide buildings in the area with an optimal indoor climate. In the case of Singapore District Cooling, chilled water is produced by production plants and distributed by water pipes contained within the common services tunnels. Specially designed units within each building draw on the cooling properties of the water to, for instance, lower the temperature of the air passing through the air-conditioning system. There are three interconnected plants in Marina Bay spanning a total of about 19,000 sq m – the other two plants are at One Raffles Quay and One Marina Boulevard – and there are plans to grow this to five plants, so more than eight million sq m can ultimately be serviced. The success of a cooling plant lies in being able to maintain the temperature of continuous water flow at under 6 deg C. At Singapore District Cooling, that standard is met 99.9999 per cent of the time. Using a district cooling facility – as opposed to having to build and install their own plant rooms and cooling towers – helps make businesses in the area about 30 per cent more energy-efficient. In temperate countries, similar networks can be used to supply heating, as is the case with Keppel’s District Heating and Cooling Systems plant at the Sino-Singapore Tianjin Eco-City in China. Keppel also has three district cooling plants. They are located in Changi Business Park, Biopolis and Woodlands. While it is more common in the United States and the Middle East, district cooling is catching on in Asia, said Singapore District Cooling managing director Jimmy Khoo, adding that the Marina South substation is a “true success story for Singapore”.
