The Straits Times, 5 March 2015

SP Group starts vehicle-to-grid technology trial � THU, JUL 08, 2021 - 9:24 PM | UPDATED THU, JUL 08, 2021 - 9:35 PM TAY PECK GEK � peckgek@sph.com.sg � @PeckGekBT Jimmy Khoo, chief executive of SP PowerGrid, with the V2G-capable Nissan LEAF and a V2G bi-directional charger that will be used in the Singapore trial. NATIONAL grid operator SP Group (SP) has started its trial of vehicle-to-grid (V2G) technology and has raised its investment in a V2G technology rm as Singapore progresses towards wider adoption of electric vehicles (EVs). The company aims to test the viability of tapping the energy stored in EVs in the trial to enhance the reliability of the grid, which will need to support more than 600,000 vehicles when Singapore phases out internal combustion engine vehicles by 2040, said SP in its media statement on Thursday. When charged, EVs store energy in their lithium-ion batteries, which serve as small energy storage systems that can transfer energy back to balance the power grid, such as when renewable energy sources such as solar power fluctuate due to weather conditions. If V2G technology is viable, owners of EVs can be paid for the use of their batteries when they are tapped to mitigate the intermittency problem in other energy sources. SP has stepped up its investment in the V2G technology rm The Mobility House (TMH), but did not provide the speci cs. SP only stated that TMH has a presence in Munich, Zurich and Belmont (in California) , and provides a non-proprietary software for integrating vehicle batteries into power grids using intelligent charging and storage solutions. SP is providing four V2G charging points at SP's premises for the trial, which will be completed in June 2022. V2G technology allows energy transfer between the batteries within an EV and the power grid, and so is more sophisticated than uni-directional charging of EVs.

News Release SP Group starts trial of vehicle-to-grid integration to pave the way for greater EV adoption Singapore, 8 July 2021 – SP Group (SP) today announced the start of its trial of vehicle-togrid 1 (V2G) technology. A first in Southeast Asia, SP will test and verify the possibility of tapping energy stored in electric vehicles (EVs) to enhance grid reliability to cater for the demand on the power grid to support more than 600,000 2 vehicles when Singapore phases out Internal Combustion Engine vehicles by 2040. When charged, an electric vehicle stores energy in its Lithium-ion batteries. The vehicular batteries can act as small Energy Storage Systems (ESS). When renewable energy sources such as solar power fluctuate due to weather conditions, these ESSs can be a key solution to transfer energy back to balance the power grid. If V2G technology is proven viable, it can be a win-win for the electricity system and EV owners, acting as a cost-effective solution to supplement the larger ESSs to overcome intermittency while EV owners can be paid for use of the EV batteries when needed. As the national power grid operator and a leading player in sustainable energy solutions, SP Group is taking the lead to harness V2G technology and cater for this increased demand while maintaining world-class reliability and stability of the grid. SP is providing four V2G charging points at SP’s premises for the trial which will be completed in June 2022. It seeks to demonstrate V2G capability and applications including frequency regulation, the injection of power from EVs to reduce demand from traditional sources, mitigation of too high or low voltage in the distribution system, and EV charging during peak and off-peak periods. 1 Vehicle-to-grid or V2G enables the charged power to be pushed back to the power grid from the battery of an electric car to balance variations in energy production and consumption. 2 Source: Land Transport Authority, 2020 1 Mr Stanley Huang, Group CEO, SP Group, said: “Our trial of vehicle-to-grid integration is another step towards supporting Singapore’s green energy transformation. At SP, we have dual roles to play. As the national grid operator, we are building a resilient and smart grid for the future, ensuring that our energy system caters to the increased load due to the conversion to EVs. To empower a sustainable energy future, we are proactively investing in and leveraging smart energy solutions to enhance our grid’s capacity for renewable energy sources.“ SP announced its investment in The Mobility House (TMH) in September 2020 to explore vehicle-to-grid feasibility, and is increasing its investment in the V2G technology leader in Europe. Operating from Munich, Zurich and Belmont (California), TMH provides a nonproprietary software for integrating vehicle batteries into power grids, using intelligent charging and storage solutions. What is vehicle-to-grid? • V2G technology allows energy transfer between the batteries within an EV and the power grid. This is more sophisticated than uni-directional charging of EVs. • The application of V2G technology could balance and support our energy grid. • Renewables such as solar power is intermittent and managing this intermittency is important to ensure a stable power supply to customers. Mitigating intermittency has traditionally been performed by power plants. With energy storage solutions integrated with V2G technology, customers are able to contribute as well. When solar generation drops due to rain or cloud cover, the EVs plugged into the system can balance out the fall in supply. During periods of significant solar generation, the EVs can store the excess energy. • With a well-functioning V2G landscape, customers can play a more active role and our energy system would be able to accommodate larger capacities of renewable energy. -Ends- 2 Photos Mr Jimmy Khoo, CEO of SP PowerGrid, with the V2G-capable Nissan LEAF and V2G bidirectional charger that had just arrived in Singapore for the trial.

Annex 1 Key Projects Featured 1) Scone Project Brief Scone aims to increase renewable energy generation in Singapore significantly using a solar cone. The solar cone is a hybrid that uses solar cone and solar-concentrating lenses to maximise energy absorption onto a solar cell. This cone promises to produce more than five times the energy than a conventional solar panel. It is essentially a higher efficiency concentrator photovoltaic that aims to harness more energy per unit area. Utilising solar technology, a heat exchanger and a cone structure, the cone generates both solar and thermal energy. There is intention to implement the solar cone at the rooftop of residential units as it allows excess heat to be converted to heated water for residential usage. This technology taps on expertise from district cooling. Benefits to customers As it is expected to generate more than five times solar energy as compared to a conventional solar panel, customers using this technology can offset their consumption, thus leading to a lower utilities bill. 2) Cloud Nine Project Brief This project uses the collection of rainwater at the top of high-rise buildings to harvest gravitational potential energy as it falls from the top of the building to the ground. This is especially relevant in Singapore with a large population of tall buildings. By retrofitting these buildings with the team’s proposed mechanism – channelling the rainwater collected on rooftops down the buildings – it will generate energy through the process for storage and subsequent usage. Benefits to customers It uses the energy generated by falling rainwater as an alternate source of renewable energy generation besides solar and wind. It is suitable for countries that face land constraint like Singapore. The use of gravitational force and turbine increases the efficiency to harvest usable energy that can power up a 12-Watt LED light bulb for 21,150 hours. This could potentially translate into cost savings to residents, building management and Town Councils, possibly resulting in lower maintenance fee in the long-term. *** Annex 1 (cont’d) 3) Savez Project Brief Savez’s product is solar cell that mimics photosynthesis for organic, highly sustainable, and versatile energy use. Benefits to customers This product is sustainable, scalable and organic. It is also cost-efficient to produce. *** 4) GreenLoco Project Brief This idea is to use human movement to self-generate electricity. It focuses on crowdsourcing energy, merging piezoelectric technology, wireless power transmission as well as Singapore’s high population density. Benefits to customers This product allows customers to self-generate electricity and raise awareness of energy issues, allowing Singaporeans to contribute to the main grid. *** 5) RoadX Project Brief RoadX is a power generation and transmission solution for Singapore’s roadways. It combines the use of solar panelled, piezo-electric charging roads and roadside wind turbines with dynamic wireless charging through induction for electric vehicles. The plan to vary the usage of each component to suit local traffic conditions of roads. Benefits to customers RoadX aims to help customers reduce carbon emission and fossil fuel dependency.

Media Release Utilities Bill Redesigned To Help Consumers Be More Energy And Water Efficient SINGAPORE, 1 AUGUST 2016 - From August, residential consumers will receive a redesigned utilities bill to help them track and take steps to reduce their energy and water consumption. This initiative is a joint effort by SP Services, Energy Market Authority (EMA), PUB and City Gas. 1. The utilities bill was redesigned with inputs from usability tests with the public. The new layout allows consumers to view utility usage at a glance, compare the average consumption of neighbours living in similar housing types or streets as well as the national average, and learn how they could be more efficient in their consumption. Highlights from the redesigned bill include: A concise bill summary to easily view one's account information; Consumption graphs on the front showing previous months' usage and comparisons with neighbours' and national average consumption; Personalised tips and advice on how to be more energy- and water-efficient; The use of icons for improved clarity; Larger text to emphasise important information such as "Total amount". More information can be found in ANNEX A.   2. Managing Director of SP Services, Mr Chuah Kee Heng, said: "We designed the bill to help customers adopt more energy- and water-efficient habits. At a glance, they can clearly see their charges, consumption for the past five months and compare it with their efficient neighbours as well as the national average. It is one of several initiatives we have introduced to help customers make energy saving a way of life." 3. EMA Chief Executive Ng Wai Choong said: "The redesigned hardcopy utilities bill makes energy savings information more accessible to households. This hopefully encourages them to adopt energy-efficient measures in their homes. Improving energy efficiency is a key strategy. It helps us achieve our energy objectives by reducing our dependence on energy imports, enhancing our economic competitiveness, and cutting down carbon emissions." 4. Ms Chew Siow Nee, Chief Financial Officer of PUB, the national water agency, said: "To ensure water sustainability in the long run, we need to manage not only water supply but also water demand. It is important that people understand their role in conserving water. And, a well-designed bill can help them track their usage at a glance. Currently, we use 151 litres of water per person per day. Let’s work towards achieving only 140 litres per person per day by 2030." 5. Mr Kenny Tan, Chief Executive Officer of City Gas, said: "City Gas welcomes SP Services' redesigned utilities bill. It is a fresher and more user-friendly design. Our customers will be able to easily read their consumption and compare with their recent usage trends.

In 2018, SP launched Project FUSION, which stands for Future Skills in Everyone, with a structured career and development road map to enhance employability of staff. This has resulted in workers undergoing continuous training and upskilling in readiness for evolving industry needs, and benefitting from job transformation. Since then, SP has invested $52 million in its employees’ training and development, with 1.1 million training hours clocked. Technical officers Goh Yap Meng and Muhammad Shamil bin Abu Bakar are among SP’s employees who have undergone further education and training to be equipped for career progression and job transformation. The most recent joint effort between SP and UPAGE is Project Silver+ to pre-emptively address potential challenges faced by mature workers at the workplace. Key solutions implemented include modifications to facilities at work areas, the provision of age-friendly work tools and aids, and programmes that boost wellness and retirement adequacy. In tandem with skills upgrading and systematic job progression, SP regularly reviews and revises its employees’ wages to ensure these remain competitive and in line with Progressive Wage Model guidelines. Working closely with UPAGE, SP started a scheme to uplift the earnings of lower income earners by doubling their annual wage increment as part of efforts to provide meaningful wage growth for lower wage employees.   Receiving SP Group’s award at a ceremony on 10 May 2024, Group Chief Executive Officer Stanley Huang said, “We are honoured to receive this highest award for employers, with strong endorsement from UPAGE. It serves as a testament to our long-standing union-management partnership towards building a workforce well-equipped for the diverse and evolving needs of the industry. Our employees are instrumental in upholding Singapore’s world-class energy network reliability, and advancing SP’s sustainable energy solutions for customers.”     General Secretary of UPAGE Abdul Samad Abdul Wahab echoed the Union’s shared commitment to enhancing employability and welfare of workers. He said, “Our journey with SP Group has resulted in joint initiatives to meet the needs and aspirations of workers across the ranks. These holistic efforts have enabled workers to level up their competencies and perform roles that are valuable for the energy sector today and in the future. Our workers are also assured of competitive wages and having their well-being cared for. - Ends -

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 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 Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks

The 38-year-old Principal Engineer is part of the team designing and building the first centralised cooling system (CCS) for a residential estate in Singapore – in the Tengah eco-town. Instead of individual compressor units mounted on aircon ledges, Mr Liu is tasked to build a centralised system which circulates chilled water to and from each flat to cool air within the flat, thus delivering air-conditioning service to 19,000 households in the estate. The first homes will be ready in 2023. “It is definitely a challenge because we have to work with many other parties to overcome the space constraints,” says Mr Liu. In his previous posting in SP Group, Mr Liu worked at an underground district cooling system that serves the Marina Bay central business district. But this time, Mr Liu has to deal with space constraints of a different kind. “In HDB flats, it’s not cost-efficient to have large underground spaces, so we have to think out of the box and find space for our cooling equipment,” Mr Liu shares. Eventually, the project team decided to place the CCS equipment on the HDB block roof, which would allow precious ground space to be used by the community. HDB flat rooftops would host the CCS equipment which service a cluster of HDB blocks. This arrangement would optimise the cooling output of the CCS equipment, achieving both energy efficiency and supply reliability. Mr Liu is proud that he plays a part in transforming the energy sector to meet climate goals.

We are helping to improve lives by the meaningful transformation of the power industry. This brings me a lot of satisfaction as an engineer,” he says. Reaping benefits from economies of scale In a CCS, a few interconnected centralised plants produce chilled water which is piped to individual households. “Colder” chilled water produced at the centralised plants is circulated to the indoor air-conditioner (known as chilled water fan coil unit or FCU) in each flat. The FCU recirculates the air within the flat and cools the air. In the process, the chilled water is “warmed” up. The warmer water is then returned to the centralised plants to be chilled again and repeat the process. Because the centralised chilled water plants are 30 per cent more energy efficient by design than individual split units found typically in households, CCS is more economical for air-conditioning of flats. Mr Liu Yue is the deputy lead for the construction of the centralised cooling system that will deliver air-conditioning service to 19,000 households in Tengah eco-town. PHOTO: SP GROUP Air-conditioned comfort with lower emissions Air-conditioning is ubiquitous in tropical Singapore. According to the Department of Statistics, about 80 per cent of Singapore households own air-conditioners, and from NEA household electricity consumption profile, air-conditioning contributes about 24 per cent of the average household electricity consumption. With rising incomes and warming temperatures, air-conditioning ownership and the use of air conditioners are set to rise. Worldwide, the use of air-conditioners results in the emission of nearly two million tonnes of carbon dioxide every year, or about 4 per cent of the global share. There is therefore an increasing need to reduce carbon footprint from more energy efficient air-conditioning systems. The reduction in electricity consumption from CCS will contribute towards Singapore’s ambitious carbon footprint reduction commitments. Singapore aims to accelerate its timeline to reduce greenhouse gas emissions, peaking emissions in 2030 and achieving net-zero emissions by 2050. While Singapore’s carbon emissions represent a small percentage of the global share (0.13 per cent in 2020), Singapore’s per capita emissions are very high, about twice the global average at 12 tonnes annually. If Singaporeans can reduce their carbon emissions significantly, it would demonstrate how people can meaningfully counteract climate change without severely lowering their standard of living. Mr Liu is energised by his contribution to help Singapore meet its climate goals. “The CCS we are building will enable Tengah residents to lower their carbon footprint through an energy-efficient cooling system. Just by living in the estate, each resident has already started the sustainability journey. This is a huge motivating factor to every engineer working on the Tengah project. “We started from ground zero and had our fair share of roadblocks in the journey. With all the hard work we put in, it is very rewarding to see everything come to fruition. I am glad to be able to play a part in pioneering the most futuristic town in Singapore towards smart and sustainable living. I guess it's my way of leaving my mark – a green one,” adds Mr Liu. Energy-efficient cooling for a warming world Leading the effort for more efficient cooling systems, SP Group will be implementing various types of cooling systems in different capacities, both in commercial and residential buildings. Its flagship district cooling system in the Marina Bay CBD network will be expanding to cool 28 commercial buildings by 2026. The savings in electricity consumption is estimated to reduce about 20,000 tonnes of carbon emissions annually, equivalent to removing 17,672 cars off the road. SP Group is establishing Singapore’s largest industrial district cooling system for STMicroelectronics at the Ang Mo Kio Technopark. By the time it is operational in 2025, it will reduce carbon emissions by up to 120,000 tonnes annually. SP Group is also constructing a distributed district cooling network in Tampines, where seven existing buildings will be retrofitted by 2025. Transitioning the world into a decarbonised future Beyond its role as the national grid operator, SP Group actively pursues sustainability initiatives as a key part of Singapore’s climate strategy. Its climate initiatives include a nationwide electric vehicle (EV) charging network, deploying rooftop solar energy generation, and smart electricity metering to monitor and reduce usage. SP Group has also exported these technologies to overseas markets where there is demand for sustainable energy solutions.

PHOTO: SCREENGRAB FROM GOOGLE MAPS Lee Nian Tjoe Senior Transport Correspondent PUBLISHED JUN 30, 2022, 5:40 PM SGT SINGAPORE - Residents in Tengah town will have access to various electrified Toyota models through a car-sharing pilot between Toyota distributor Borneo Motors and energy provider SP Group. The announcement was made at a signing ceremony for the memorandum of understanding between the two parties on Thursday (June 30). When launched in June next year, the cars can be booked through the SP smartphone app or the Kinto Share app operated by Borneo Motors. This will be the first time that users of SP Group's services can hire a car through its smartphone app. Ms Jasmine Wong, the chief executive of Inchcape Singapore and Greater China, which owns Borneo Motors, said: "With this initiative, we combine our expertise in electrified vehicles with SP Group's eco-charging solutions to embark on a significant step in steering the nation towards a more responsible and sustainable way of living." In addition, Borneo Motors and SP Group will set up an innovation and experience centre in the housing estate to help Tengah residents learn about sustainable mobility solutions. Borneo Motors launched Kinto Share last year for its on-demand car-sharing service with Lexus models. On its website, prices for daily rental start from $198. The collaboration with SP Group will see the vehicles being parked at dedicated carparks in the Tengah township. The exact details are still being worked out. This is the first time Kinto Share will serve a housing estate. Currently, users of the car-sharing service pick up the vehicles from the Lexus Boutique in Leng Kee Road. They can also pay for doorstep delivery and retrieval. SP Group and Borneo Motors are also conducting joint research in electrification, focusing on areas such as user behaviour and vehicle energy consumption, to further develop their future electric mobility programmes. The pilot, which runs for five years, will initially have eight Toyota models, seven of which are hybrids that do not require access to an EV charger. The eighth is the bZ4X, the Japanese car brand's first fully-electric vehicle, which will be officially launched in Singapore by then. A plug-in hybrid model is said to be in the pipeline. To encourage take-up, Tengah residents will be offered preferential rates for both the car rental and EV charging. Located in the western part of Singapore, Tengah consists of five districts with 42,000 residential units. Touted as a "smart-energy town", it features EV-ready carparks.

SP Group Offers EV Full Charging In 30 Minuteshttps://www.spgroup.com.sg/about-us/media-resources/news-and-media-releases/SP-Group-Offers-EV-Full-Charging-In-30-Minutes Media Release SP Group Offers EV Full Charging In 30 Minutes Singapore, 9 January 2019 – Electric vehicle (EV) users can now fully charge their vehicles in 30 minutes at SP Group’s (SP) island-wide charging network, with the largest number of fast direct current (DC) chargers. SP is building Singapore’s largest public EV charging network with 1,000 points, including 250 DC charging points, by 2020. SP’s first wave of 38 charging points are located at commercial buildings, industrial sites and educational institutions. (See Annex for the list of charging locations) The locations are close to amenities such as food centres, offering drivers greater convenience while waiting for their vehicles to be charged. There are 19 high-powered 50kW direct current (DC) charging points and the other 19 are 43kW alternating current (AC) charging points. These are among the fastest EV charging points in Singapore. The 50kW DC chargers can fully charge a car in 30 minutes. Over the next few years, SP will introduce more high-powered DC charging points of up to 350kW. Other than SP’s, there are six other DC chargers in Singapore. SP’s new additions will be a game-changer in improving the charging turnaround time for EV drivers in Singapore. EV drivers can also enjoy at least 50 per cent cost savings compared to typical Internal Combustion Engine (ICE) vehicles for every kilometre travelled. The cost of using SP charging points will be regularly adjusted, mainly influenced by the prevailing electricity costs in Singapore. “Our nation-wide public charging network offers EV drivers fast charging, with greater convenience and a seamless experience through our digital solution, at cost-competitive rates. This will encourage wider adoption of green mobility in Singapore, and enable drivers to save cost,” said Mr Wong Kim Yin, Group Chief Executive Officer of SP Group. EV drivers can use SP Group’s charging service through the SP Utilities mobile application where they can search for the nearest available charging points, receive updates on their charging sessions and make payment. This first wave of locations includes Singapore Polytechnic. The SP charging points there will also serve as an education and research platform, as part of Singapore Polytechnic’s engineering curriculum to train students and adult learners. Thought this collaboration, SP Group and Singapore Polytechnic aim to develop new skills related to EVs and related charging technologies for Singapore. SP Group is also showcasing its charging points at the Singapore Motorshow 2019 at Suntec City from 10 to 13 January 2019. They will be located at the BMW and Hyundai booths.

SP is building Singapore’s largest public EV charging network with 1,000 points, including 250 DC charging points, by 2020. SP’s first wave of 38 charging points are located at commercial buildings, industrial sites and educational institutions. (See Annex for the list of charging locations) The locations are close to amenities such as food centres, offering drivers greater convenience while waiting for their vehicles to be charged. There are 19 high-powered 50kW direct current (DC) charging points and the other 19 are 43kW alternating current (AC) charging points. These are among the fastest EV charging points in Singapore. The 50kW DC chargers can fully charge a car in 30 minutes. Over the next few years, SP will introduce more high-powered DC charging points of up to 350kW. Other than SP’s, there are six other DC chargers in Singapore. SP’s new additions will be a game-changer in improving the charging turnaround time for EV drivers in Singapore. EV drivers can also enjoy at least 50 per cent cost savings compared to typical Internal Combustion Engine (ICE) vehicles for every kilometre travelled. The cost of using SP charging points will be regularly adjusted, mainly influenced by the prevailing electricity costs in Singapore. “Our nation-wide public charging network offers EV drivers fast charging, with greater convenience and a seamless experience through our digital solution, at cost-competitive rates. This will encourage wider adoption of green mobility in Singapore, and enable drivers to save cost,” said Mr Wong Kim Yin, Group Chief Executive Officer of SP Group. EV drivers can use SP Group’s charging service through the SP Utilities mobile application where they can search for the nearest available charging points, receive updates on their charging sessions and make payment. This first wave of locations includes Singapore Polytechnic. The SP charging points there will also serve as an education and research platform, as part of Singapore Polytechnic’s engineering curriculum to train students and adult learners. Thought this collaboration, SP Group and Singapore Polytechnic aim to develop new skills related to EVs and related charging technologies for Singapore. SP Group is also showcasing its charging points at the Singapore Motorshow 2019 at Suntec City from 10 to 13 January 2019. They will be located at the BMW and Hyundai booths.

In recent years, our estate has been undergoing a green facelift to create a more sustainable living environment for residents. For example, we have piloted Eco Boards at lift lobbies to help residents track how much electricity and water they use as a block. We also contributed to the national renewable energy drive through the installation of solar panels on our blocks and implemented programmes to recycle food waste. These were very well received by Tampines residents and encouraged a sustainability culture at the neighbourhood level. Encouraged by these successes, we are now looking at how we can enable commercial buildings to adopt sustainable practices. Apart from being a residential estate, Tampines is also an active and mature business hub, home to an industrial park, several office complexes, and a cluster of shopping malls. There are many opportunities to do more in this area. Hence, we have offered Tampines Central as a testbed for an innovative cooling concept, known as the Distributed District Cooling (DDC) network. Conceived by SP Group, the network is a novel approach to district cooling in a brownfield development, allowing the building owners to use less energy for their cooling needs as a whole. The results of the feasibility study look promising. There is a potential of 18 per cent fall in carbon emissions – equivalent to removing 2,250 cars from the roads annually – when the DDC network takes off. This is the first time in Singapore where existing buildings in a brownfield site pool together their resources to achieve substantial carbon footprint savings. Another first for Tampines! I hope that the study will pave the way for such solutions to be explored in other townships and brownfield sites, contributing to our national sustainability efforts. One challenge that we have observed confronting building owners is energy consumption. A large part of the energy consumed in commercial buildings goes to cooling. Taking The Heat Off Cooling: A Greener Way to Cool Forewords 05 Ms Amy Hing 1 Deputy Secretary, Ministry of Sustainability and the Environment Climate change poses an existential challenge for Singapore. Sea level rise threatens our island nation, while changes in the climate jeopardise our access to essential resources such as water and food, and have consequences for public health and diseases. The Centre for Climate Research Singapore projected that by 2100, daily mean temperatures in Singapore could rise by up to 4.6 degrees Celsius. Days with peak temperatures hitting 40 degrees Celsius may appear as early as 2045. We are already experiencing such effects; four out of the last six years are amongst the top 10 warmest years recorded in Singapore. We need a whole-of-nation effort to address climate change. The Singapore Green Plan 2030 is our roadmap towards sustainable development and to achieve our long-term net-zero emissions target as soon as viable. It involves everyone – from individuals and communities to businesses and the public sector. A key pillar of the Green Plan is Energy Reset, which looks at how we can use cleaner energy and increase our energy efficiency. This is particularly relevant for our towns, which require energy for cooling needs. This study by Temasek and SP Group explores an innovative district cooling solution in a brownfield site that can potentially lower the carbon footprint while addressing the needs of residents and businesses in our tropical climate. I hope that the data and insights gained from the feasibility study will encourage more ideas and collaboration on innovative district-level solutions, bringing us closer to our goals under the Green Plan.

As we see the consequences of climate change all around us, we know our window to act has been reduced. We must move with renewed urgency and greater ambition to decarbonise across sectors. One key sector is the built environment, which contributes close to 40 per cent of global energyrelated carbon emissions. A significant portion of this comes from the energy consumed by buildings, predominantly for heating or cooling. In tropical regions like Singapore where the weather is hot all year round, the demand for cooling will only increase and a more efficient way to cool buildings could significantly reduce their energy consumption and carbon emissions and reduce the burden on household budgets. We need a tripartite effort from businesses, governments, and investors to rethink the way buildings and districts are designed, built, and operated. This has the potential to generate significant economic benefits, such as reduced lifecycle costs for buildings. Temasek’s wide network of partners makes it possible to help bring together the different stakeholders necessary to address this challenge. Temasek is delighted to partner with SP Group to study the feasibility of a novel distributed district cooling concept for brownfield developments, which could provide a proof-of-concept for developed cities worldwide. Sustainable development underpins Singapore’s long-term goal to build a resilient future. Enabling urban decarbonisation is pivotal to this vision. In land-scarce Singapore, we must constantly innovate our built environment to optimise land and building resources as well as minimise our carbon footprint. In Singapore, with air-conditioning accounting for up to 50 per cent of the total energy consumed in a building, we need to redesign how interiors can be cooled in a sustainable and costeffective manner. Therein lies the solution of a district cooling network. Its benefits are fourfold: enhances energy savings, lowers cost of cooling, improves land use, and reduces carbon emissions. These are validated through SP Group’s proven track record of 100 per cent reliability and up to 40 per cent improvement in energy efficiency in building and operating Singapore’s first district cooling project at Marina Bay since 2006. We are also developing Singapore’s first residential centralised cooling system for the Tengah precinct. We are optimistic this feasibility study on a distributed district cooling network in Tampines will yield business and environmental benefits. This will pave the way for existing buildings and districts to go green and lay the cornerstone for future eco-districts. Sustainability is central to our long-term strategy, and it requires the collective effort and collaborative partnership of building owners, government agencies, the community and solution providers such as SP Group. Together we can harness our combined strengths to enable widespread adoption of sustainable energy solutions in Singapore and build green energy ecosystems for commercial districts, residential towns, and campuses for a greener and better future. Taking The Heat Off Cooling: A Greener Way to Cool Executive Summary 07 Executive Summary 2011 to 2020 was the warmest decade on record. Earth’s six warmest years have all occurred since 2015 – yet another sign of global warming’s grip on the planet. Researchers around the globe have cautioned that this trend will not only continue, but also increase in extremity. As temperatures climb, cities are desperate to stay cool. Unfortunately, the current simplest and most mainstream solution worsens the problem – air-conditioning. They are energy guzzlers, generate more waste heat than cooling, and contribute to climate change by emitting hydrofluorocarbons, chemicals that trap heat in the atmosphere at alarming rates. There is a critical need to find a better way to cool down our living environment. One solution that has gained traction across the globe is district cooling – central cooling plants that supply chilled water to various buildings through an underground network of insulated pipes. These plants consume less energy for the same amount of cooling, free up space, and reduce lifecycle costs as buildings do not need to invest in their own chillers. Such systems are already being used in Singapore, such as the Marina Bay district – cooling more than a dozen buildings in the area, including Marina Bay Sands, the Marina Bay Financial Centre, and One Raffles Quay. There is, however, a limitation to the way district cooling systems are currently built. They are typically incorporated into the design of a new development, and hence are more suitable for greenfield sites. For built-up or brownfield sites with buildings that already have their own chiller plant systems, it becomes much harder to introduce district cooling. Hence, a novel approach – a distributed district cooling (DDC) network – is being explored in Tampines Central, under the Tampines Eco Town initiative. It was conceptualised by SP Group, a leading energy utilities company. In the DDC network, existing cooling systems of selected buildings will produce chilled water for their own cooling needs and that of other buildings within the district. A preliminary feasibility study was conducted on this DDC network concept in Tampines Central, and the results were promising. In one year, the DDC network could potentially achieve: A 17% reduction in energy consumption - enough to power 1,665 three-room HDB households for a year A 18% fall in carbon emissions from both energy savings and refrigerant reduction – equivalent to removing 2,250 cars from roads per year S$4.3 million in annual economic value from energy, equipment replacement and maintenance cost savings, as well as potential earnings from leasing out freed-up chiller plant space The findings show that the DDC network would be able to lower energy consumption and carbon footprint. It is a possible game changer that could green entire developments at one go – an attractive solution for brownfield sites such as industrial estates and existing townships. With Singapore announcing the Singapore Green Plan 2030 to address climate change and promote sustainable living, district cooling networks could open the door to a cooler and cleaner future. Studying the Impact of a Brownfield Distributed District Cooling Network in Singapore The Hot Issue of Keeping Cool 08 The Hot Issue of Keeping Cool • As temperatures rise, so does the use of air-conditioners. There are over one billion air-conditioning units in the world right now – a number that is expected to increase to 4.5 billion units by 2050. • These electrical appliances consume large amounts of energy to bring temperatures down. Cooling systems typically make up about 40 to 50 per cent of a building’s total energy consumption. • But beyond cooling you down, air-conditioners can also leak potent greenhouse gases that exacerbate climate change – leading to even higher temperatures. Air-conditioners commonly use hydrofluorocarbons (HFCs) as refrigerants, which are 116 to 12,400 times more efficient at trapping heat than carbon dioxide. • The heat is on to find a more efficient way to cool. The air-conditioner is hailed as one of the most important inventions in modern history, allowing people to control and cool the weather inside. But after removing the heat and humidity indoors, airconditioners in fact lead to warmer temperatures outside, contributing to the Urban Heat Island (UHI) 1 effect. Singapore has the highest per capita installed rate of air-conditioning among the Association of Southeast Asian Nations (ASEAN) countries, with about 80 per cent of households owning air-conditioners. While air-conditioners can provide thermal comfort, they consume a lot of energy to do so. Air-conditioning currently accounts for up to 24 per cent of the average household electricity bill in Singapore. For an entire commercial building, cooling systems typically make up 40 to 50 per cent of its total energy consumption. Air-conditioners also often use hydrofluorocarbons (HFCs) that trap heat – making them potent greenhouse gases that contribute to climate change should they leak into the atmosphere. In fact, the concentration of HFCs in the atmosphere is growing at a faster rate than that of all other greenhouses gases, and studies have shown that their growth could cancel out the entire benefit of controlling carbon dioxide (CO 2 ) emissions. On the whole, this means an enormous drain on power and a comparable jump in carbon emissions should electricity generation in Singapore continue to be dominated by fossil fuels – a future that Singapore is determined to avoid. The city-state aims to halve the amount of emissions it produces from its 2030 peak by 2050, eventually achieving net-zero emissions as soon as possible in the second half of the century. 1 The Urban Heat Island (UHI) effect refers to a phenomenon where urban areas face higher temperatures than its surrounding rural areas. It is caused by the heat generated from human activities and trapped by urban surfaces such as buildings and roads. Taking The Heat Off Cooling: A Greener Way to Cool The Hot Issue of Keeping Cool 09 DID YOU KNOW? In Singapore, urban built-up areas can be up to 7°C warmer than areas that are more rural. Recognising the need for more sustainable living, the Ministry of Sustainability and the Environment (MSE) set up a SG Eco Office in March 2020 to spearhead and coordinate sustainability projects across Singapore. Cooling is an important part of this work. Building owners, developers, and regulators need to rethink their cooling systems. One town that is doing so is Tampines, which is transforming into an Eco Town where the spirit of sustainability is built into its infrastructure and instilled in its community. It has piloted dashboards at the lift lobbies of several residential blocks to help residents track electricity and water usage as a block, introduced programmes to recycle food waste, and potentially having the greatest impact – it is studying the possibility of implementing a novel distributed district cooling network. This report takes a closer look at a preliminary feasibility study on a proposed cooling network that involved 14 commercial buildings in Tampines Central. The following sections will include details of the study’s methodology, and the resulting energy savings and reduction in carbon emissions among the buildings. Studying the Impact of a Brownfield Distributed District Cooling Network in Singapore District Cooling 101 10 District Cooling 101 • District cooling is a modern and efficient way to provide air-conditioning for a network of buildings, where chilled water is supplied from centralised cooling plants. • The benefits of district cooling include enhanced energy savings, lowered lifecycle costs, and reduced carbon emissions. A District Cooling System Imagine a giant air-conditioner that can cool an entire district of buildings, rather than just individual buildings – but greener and more energy efficient. How does it work? 1 Chilled water is generated in a central cooling plant. 2 A closed loop network of underground insulated pipes distributes the chilled water to each customer’s building. OFFICE BUILDINGS RETAIL BUILDINGS COMMUNITY CENTRES 3 When the chilled water reaches the customer’s building, energy transfer stations within each building circulate the cold energy from the network into the building’s airconditioning system, which dehumidifies and cools the air. COOLING TOWERS 3 4 4 The warmer water is then circulated to the cooling plant, via the return pipes, to be chilled again. The whole process repeats itself. 5 2 Chilled water (4 to 7°C) Warmer water (12 to 14°C) 5 Thermal storage tanks (if used*), are designed to store cold energy, in the form of ice or chilled water. Thermal storage tanks help to regulate cooling demand and provide resilience. 1 Energy transfer station CENTRAL COOLING PLANT Thermal storage tank *Not all district cooling system plants deploy thermal storage tanks. Taking The Heat Off Cooling: A Greener Way to Cool District Cooling 101 11 Benefits of district cooling systems Improves efficiency A chiller plant system in one building is unlikely to be operating at its optimal efficiency at all times due to partial loading conditions. This is typical during actual operations, where the cooling demand of a building fluctuates. However, a district cooling system is expected to operate closer to its optimal efficiency level most of the time as it will accurately select the most suitable mix of chillers to meet the aggregated cooling demand. Saves energy Larger systems typically consume less electricity for the same amount of cooling due to economies of scale, which improves the energy efficiency of the system. When combined with thermal storage capabilities, the system can further reduce peak electricity demand for cooling by shifting chilled water production to periods where there is less demand on the electricity grid. Frees up space Each building no longer needs to house its own cooling equipment, which means that building owners are able to use the freed-up space for other purposes, or even lease them out. Cuts costs Building owners no longer need to buy their own chillers or incur operating and maintenance costs. The need to invest in additional chillers to buffer for potential increases in cooling needs and provide redundancy is also eliminated. Reduces carbon footprint With an overall reduction in refrigerants used, the amount of harmful HFCs emitted into the environment will be reduced as well. In addition, a reduction in overall energy consumption will in turn lower carbon emissions. Provides the network effect The initial cost of building the district cooling infrastructure may be high. However, once the infrastructure is laid, the cost of connecting an additional building will be significantly lower. Over time, the benefits that the system brings to customers would significantly outweigh the costs of connecting them to the network. Studying the Impact of a Brownfield Distributed District Cooling Network in Singapore District Cooling 101 12 CASE STUDY A cool secret beneath Marina Bay Lying 25 metres beneath the ground in Singapore’s Marina Bay district is the world’s largest underground district cooling system. Designed, built, and operated by SP Group, the system produces up to 35,000 refrigeration tons (RT) of chilled water each hour, and serves 16 developments in the area, including Marina Bay Sands, the Marina Bay Financial Centre, and One Raffles Quay. Water is chilled to 4.5 degrees Celsius at two cooling plants before being transported to the buildings through five kilometres of insulated underground network pipes. The chilled water is used to provide air-conditioning for the buildings by cooling the air circulating in the occupied spaces in each building before being pumped back to the plants to be chilled again. This cycle is then repeated. The heat extracted from the buildings is carried by the water back to the plants and released into the surrounding environment through large cooling towers above ground. Building owners using the district cooling system have enjoyed significant energy savings and carbon emissions reduction. By centralising the production of chilled water and removing the need for buildings to have their own chiller plant, the district cooling system has also freed up some 25,000 square metres of prime land space for other uses, such as the Marina Bay Sands infinity pool, which is also the world’s largest rooftop infinity pool. Building owners using the system have enjoyed significant energy savings and carbon emissions reduction. The system has also freed up some 25,000 m 2 of prime land space for other uses. Taking The Heat Off Cooling: A Greener Way to Cool 13 Can district cooling be applied to existing developments? Given the engineering complexity and the significant upfront infrastructure costs involved, a district cooling system is typically introduced in greenfield developments, where it is integrated into the design of the development – like the Marina Bay case study. But in a highly developed city like Singapore, where majority of land has been built up and individual building owners already equipped with their own chiller plants, how can the concept of district cooling still be applied? Tampines Eco Town: A Distributed District Cooling Network 14 Tampines Eco Town: A Distributed District Cooling Network The proposed Distributed District Cooling (DDC) network comprises 14 buildings interconnected via insulated network pipes. Instead of constructing a new centralised cooling plant, buildings in the DDC network with existing excess chiller capacity act as injection nodes, supplying chilled water to cool the rest of the buildings in the network. To find out if district cooling could be applied to existing developments or brownfield sites, a study was conducted at Tampines Central. It involved 14 buildings – a mix of retail and commercial premises, and data centres – each with its own chiller plant system. An initial assessment made on the 14 buildings’ existing cooling capacity yielded the following results: A total annual cooling load of 42,897,215 RTh/year, of which 88% belonged to chiller plant loads and 12% belonged to unitary systems A current total installed cooling capacity of 25,836 RT, which exceeds the hourly peak operating cooling load of 8,395 RT by three times 88% Chiller plant loads Peak cooling load 12% Unitary systems Installed cooling capacity A unitary system refers to self-contained airconditioning that provides cooling to a localised zone. The common examples are Multi-room split units, Variable Refrigerant Volume units, and Packaged units. Unitary systems are popular among users who require cooling for a specific area that the building might not have previously catered for (e.g. tenanted space and server rooms). Unitary systems are typically less efficient than chiller-based systems. x 3x The results indicate that there were chillers operating at partial capacity and redundant chillers that were not in operation at all. This presented an opportunity to optimise the usage of the existing chiller plant systems to reduce the overall energy consumption and, ultimately, the greenhouse gas emissions of the buildings. Applying the principles of district cooling, SP Group conceptualised a Distributed District Cooling (DDC) network, where 14 buildings would be interconnected via insulated pipes that distribute and circulate chilled water in a closed loop. The key to the energy savings for the DDC network, compared to buildings operating their own chiller plants individually, lies in the concept of an integrated operation. Through the consolidation of individual buildings, the DDC network is able to choose the best combination of chillers amongst the different chiller plants to most efficiently meet the fluctuating cooling demands throughout day and night. A few existing chiller plants are chosen to serve as “injection nodes” 2 , producing and supplying chilled water to meet the cooling demands of all buildings within the network. This would allow the required installed cooling capacity to be streamlined to meet actual cooling demands, allowing the chiller systems to operate at optimum efficiency. The remaining excess capacities would subsequently be trimmed once these redundant chillers reach their end-of-life. 2 The chiller plants that were selected to serve as injection nodes typically had excess capacities (≥1000 RT) and very good energy efficiencies (≤0.68 kW/RT).

Thereafter, the total carbon emission reduction and long-term economic value were determined. More detailed information on the study’s methodology can be found in the Annex. STEP 1 What are the energy savings? Calculate the difference in the amount of energy consumed to cool the 14 buildings between the DDC network and the BAU scenario over 30 years. Calculate the resulting carbon emissions reduction from the energy savings (A), using the EMA Grid Emissions Factor. 3 STEP 2 What is the reduction in refrigerant used? Calculate the difference in the type and amount of refrigerant used to cool the 14 buildings between the DDC network and the BAU scenario over 30 years. Calculate the resulting carbon emissions reduction from the reduction in refrigerant used (B). STEP 3 What is the total reduction in carbon emissions? Total carbon emissions reduction from using the DDC system over 30 years = A + B. STEP 4 What is the long-term economic value? Calculate the economic value of the DDC network over 30 years from: • Electricity bill savings • Capacity charge savings • Carbon tax savings • Potential rental earnings if the freed-up • Equipment replacement cost savings chiller plant space were to be leased out • Operation and maintenance cost savings 3 The Grid Emission Factor (GEF) measures the average CO 2 emissions emitted per MWh of electricity generated. For the study, the EMA GEF (2019) of 0.4085 kgCO 2 /kWh was used.

This results in a weighted average system efficiency of 0.765 kW/RT from all the cooling systems across the 14 buildings. In comparison, the DDC network’s efficiency is targeted to be maintained at 0.620 kW/RT or better across 30 years. In addition, the DDC network would be operated by a third-party professional service operator and comply with the National Environment Agency’s (NEA) Minimum Energy Efficiency Standards (MEES) requirements by 2025/2029, which would help to ensure more consistent and efficient system performance over long periods. Therefore, moving to the DDC network would save the 14 buildings approximately 5,321,432 kWh of energy a year, or 17 per cent of the BAU energy consumption – enough to power 1,665 three-room HDB households. With less energy expended, carbon emissions would also be reduced. The annual average carbon
