SAFETY PERFORMANCE CRITERIA Introduction 1. With effect from 1 April 2022, all tenders called by Singapore Power Limited and its Singapore incorporated subsidiaries (SP Group) will include a tender evaluation criteria that takes into account the participating tenderer’s safety performance in their contracts with SP Group. With effect from 1 April 2023, this criteria is extended to subcontractors with LTI. 2. This is in line with SP Group’s core value that safety is our highest priority and all our suppliers and contractors must continuously adopt good safety practices and prevent accidents from occurring. Tender Evaluation Criteria 3. All open and closed tenders published on or after 1 April 2022 by SP Group shall include the new Safety Performance criteria as part of its tender evaluation criteria. 4. The Safety Performance criteria shall be a 1 st level evaluation criteria together with Price and/or Quality and shall be of a overall weightage of not less than 10% of the total evaluation score. 5. For tenders that is evaluated based solely on lowest compliant priced tender with no requirement to assess quality (e.g supply of standard items such as HP toner cartridges), the following evaluation method shall apply: Total Evaluation Score (100%) = Safety Performance (10%) + Price (90%) 6. For tenders that is evaluated based on Price and Quality factors, the following evaluation method shall apply: Total Evaluation Score (100%) = Safety Performance (10%) + Price (X%) + Quality (Y%) Where X + Y = 90% 7. For the avoidance of doubt, other safety related evaluation criteria such as the proposed safety measures to be taken for the tendered project or the tenderer’s past safety awards shall be accounted separately under the Quality score. Safety Performance 8. Safety Performance of tenderers shall be assessed by taking into account the occurrence of any Loss Time Injury (LTI) incidents in the past 2 years prior to tender closing date. In the event of the occurrence of any incidents that results in fatality or serious injury in the past 1 year prior to the tender closing date, the bid submitted by the tenderer may be rejected by SP Group. For the avoidance of doubt only incidents occurring on or after 1 April 2022 will be considered. 9. Loss Time Injury incidents for the purpose of this Safety Performance criteria refers to any incidents where: a. It is a work-related injury occurs which results in lost work time of one work day or more; b. The incident occurred while the tenderer was carrying out works under a contract with SP Group; and c. The incident occurred on or after 1 April 2022. 10. Any incidents that occur in the course of the Tenderer’s work in contracts with other parties are not accounted under this criteria’s scoring but may considered in the final decision for award.

It comprises two key models: Asset Twin1 for the health management of grid assets (such as substations, transformers, cables); and Network Twin2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for different needs (such as installation of electric vehicle chargers, and connection of solar photovoltaic systems and energy storage systems). Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network.   In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

The digital twin of Singapore’s power grid will comprise two key models: Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory3   Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)4, the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).   Key benefits of the Grid Digital Twin are: Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.   Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads.   Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.   Grid Digital Twin comprising the Asset Twin and Network Twin (Image Credit: Energy Market Authority) KEY VISUAL FOR ASSET TWIN Overview of Asset Health and Criticality Index for the Distribution Network (Image Credit: SP Group-NTU Joint Laboratory) KEY VISUAL FOR NETWORK TWIN Dashboard for analysing electric vehicle charging impact on the distribution grid using the Network Twin (Image Credit: Institute of High Performance Computing and TUMCREATE) 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources.   The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: Asset Twin1 for the health management of grid assets (such as substations, transformers, cables); and Network Twin2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections. As the Grid Digital Twin provides a more holistic model of the grid, it can facilitate planning of infrastructure for different needs (such as installation of electric vehicle chargers, and connection of solar photovoltaic systems and energy storage systems). Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network.   In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations.   Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.”   Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.”   When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.   Annex: Factsheet on the Singapore Power Grid Digital Twin -- End -- About Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

The digital twin of Singapore’s power grid will comprise two key models: Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory3   Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)4, the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).   Key benefits of the Grid Digital Twin are: Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.   Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads.   Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.   Grid Digital Twin comprising the Asset Twin and Network Twin (Image Credit: Energy Market Authority) KEY VISUAL FOR ASSET TWIN Overview of Asset Health and Criticality Index for the Distribution Network (Image Credit: SP Group-NTU Joint Laboratory) KEY VISUAL FOR NETWORK TWIN Dashboard for analysing electric vehicle charging impact on the distribution grid using the Network Twin (Image Credit: Institute of High Performance Computing and TUMCREATE) 1 The Asset Twin is underpinned by five research projects awarded by EMA to SP Group and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory. 2 The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd.

Supported by the Energy Market Authority (EMA), SP Group (SP) and the Science and Technology Policy and Plans Office (S&TPPO) under the Prime Minister’s Office, the upcoming Grid Digital Twin will serve to enhance Singapore’s grid resilience to ensure grid reliability and support the deployment of cleaner energy sources. 2 The Grid Digital Twin is a virtual representation of the physical power grid assets and network and operates using real-time and historical data. It comprises two key models: • Asset Twin 1 for the health management of grid assets (such as substations, transformers, cables); and • Network Twin 2 for the assessment of impact on the grid when connecting new energy sources or consumers to the grid. The Grid Digital Twin is currently in a prototype stage and is expected to be fully developed over the next few years. When fully deployed, it will enable SP to better plan, operate and maintain the national power grid through modelling and simulations so that the actual works can be carried out in a more effective and efficient way. (Refer to Annex for more information.) 3 Key benefits of the Grid Digital Twin include improving network planning analysis and remote monitoring of asset conditions, thereby saving manpower resources in carrying out extensive physical inspections.

Progressive enhancements to the Grid Digital Twin are in place to make it more accurate and efficient, as SP continues to digitise the existing electricity assets under the network. 4 In tandem with the Singapore Green Plan 2030, Singapore is looking to greener sources of energy and more diversification of energy supply, such as solar deployments, energy storage systems and vehicle-to-grid technologies. In addition, power grid operations will become more complex with increasing electrification and deployment of more distributed energy resources (DERs). Currently, the national power grid comprises over 18,000 transformers, with more than 27,000 km of underground cables interconnecting over 11,000 substations. The Grid Digital Twin will therefore help to future-proof our power grid, to ensure that it is well-equipped to manage such complexities while maintaining reliability of grid operations. 5 Mr Ngiam Shih Chun, Chief Executive of EMA, said, “The digital twin for our national power grid will help to enhance the reliability of our electricity supply and support our transition towards greater energy sustainability. With the pressing need to tackle climate change, the power grid needs to evolve to support a more complex power system that will connect to more diverse sources of cleaner energy as well as a growing network to meet rising demand.” 6 Mr Stanley Huang, Group Chief Executive Officer of SP Group, said, “SP Group works closely with EMA to explore measures to improve Singapore’s grid reliability and resilience. Harnessing the power of digitisation, the Grid Digital Twin enables us to monitor and test different scenarios based on a virtual replica of the grid. We can then effectively test potential upgrades and enhancements, and future-ready innovations such as the projects under the SP Group - NTU Joint Lab to support our ambition to empower the future of energy.” 7 When completed, the Grid Digital Twin will be a key initiative in contributing towards Singapore’s overall efforts for greater sustainability through enhanced grid network planning and operations.

ANNEX FACTSHEET ON THE SINGAPORE POWER GRID DIGITAL TWIN A digital twin is a virtual model of physical infrastructure, processes and systems that can carry out various functions such as intelligent data analysis, computer modelling and simulation and machine learning to support users in improving planning and decision-making processes. 2 The digital twin of Singapore’s power grid will comprise two key models: a. Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory 3 . b. Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO) 4 , the Network Twin is able to provide SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. The Network Twin is being developed by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project is funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO). 3 The SP Group - NTU Joint Lab was established between SP Group and NTU in 2020, to explore energy-related projects in the areas of asset management and network operations. 4 MESMO is one of two primary simulation technologies that is used in the Singapore Integrated Transport Energy Model (SITEM) project.

What does it mean to be a smart and sustainable city? In the eco-vanguard are Tengah’s innovative cooling system and Punggol’s open digital platform Singapore is piloting more energy-efficient technologies, including district cooling systems like the one implemented in the Marina Bay district (above) in 2006, enabling energy savings of up to 40 per cent, according to energy utilities provider SP Group. Tengah new town will be similarly equipped with a centralised cooling system adapted for residential use. PHOTO: SP GROUP test new concepts of living, working and service delivery for the neighbourhood. In Tengah, numerous initiatives – such as solar photovoltaic installations (which convert sunlight directly into electricity) and charging systems for electric vehicles, along with battery energy storage systems – are planned in an integrated manner. SP Group’s OneTengah digital platform will allow town council and facility operators to better measure, monitor and manage what systems are being deployed. Sustainable districts in a city hold huge promise for turning eco-conscious living into a collaborative endeavour. When such innovations are successfully implemented, the city is able to reap many benefits from systems-level integration and enjoy economies of scale, including energy savings. People: However, the success of these innovations ultimately rests on the people on the ground. Governments and developers can build the necessary infrastructure, but to actually reduce emissions, residents must do their part through individual lifestyle choices. A recent media survey found that nine in 10 Singaporean millennials are willing to make personal sacrifices to support climate change mitigation efforts. That’s why Tengah is designed to make it as easy and socially desirable as possible for residents to reduce their carbon footprint. One way Tengah will do this is through Eco Boards – digital displays that provide residents with block-level information on energy and water use. These will encourage utilities savings through “friendly competition” among blocks and allow town councils to achieve more efficient estate management. Additionally, the MyTengah app will allow residents to understand household utilities usage, intelligently control air-conditioning usage and buy energy-efficient appliances. Hugh Lim For The Straits Times Climate change and urbanisation are two of the most important challenges facing the world today – and they are inextricably linked. In South-east Asia, one of the most rapidly developing regions in the world, millions are moving out of rural settings into more urbanised areas every year. Sadly, this urbanisation is usually accompanied by an increase in greenhouse gas emissions. However, this need not be the case. Recent studies reveal that residents of denser city centres emit half the greenhouse gas emissions of their suburban neighbours. Moreover, cities have the unique ability to respond to a global issue such as climate change at a more local level, engaging residents directly. Cities are crucibles of innovation and usually offer more immediate and effective communication between the public and decision-makers. Therefore, cities that are well planned and managed may hold the key to balancing economic growth and environmental sustainability. REQUIREMENTS OF SUCCESS On a city scale, urban infrastructure and policies are required to drive emissions reductions through lifestyle choices. Take the example of Tengah, Singapore’s most ambitious smart and sustainable new town to date. The Housing Board, in collaboration with energy utilities provider SP Group, will implement Singapore’s first large-scale residential centralised cooling system there. Such collaborations and initiatives will aid Singapore in achieving its pledge to cap its emissions by 2030 and halve them by 2050. Its success will hinge on three things: power, process and people. Power: Geophysical constraints make it challenging for Singapore to adopt large-scale renewable energy solutions. This makes improving the performance of energy-consuming systems critical. The National Climate Change Secretariat predicts an increase in average surface temperatures of 2.9 deg C to 4.6 deg C under the RCP8.5 greenhouse gas trajectory for the period of 2070 to 2099, relative to 1980 to 2009. (RCP8.5 is a baseline scenario referring to the concentration of carbon that delivers global warming at an average of 8.5 watts per sq m across the planet.) What an increase in average surface temperatures means for Singapore is that there will be a commensurate increase in demand for air-conditioners. The amount of energy used to cool Singapore – which has the highest rate in the South-east Asian region of air-conditioners installed per capita – is projected to grow by 73 per cent between 2010 and 2030. The good news is that Singapore is piloting more energy-efficient technologies, including district cooling systems like the one implemented in the Marina Bay district in 2006, enabling energy savings of up to 40 per cent, according to SP Group. Tengah, which is scaled at around 220 to 300 HDB blocks, will be similarly equipped with a centralised cooling system adapted for residential use. Through centralised cooling, lifetime household energy consumption is expected to be reduced by 30 per cent. The upcoming Punggol Digital District, developed by national industrial infrastructure developer JTC Corporation, will be equipped with a smart energy grid that can lower energy usage, distribute green energy such as solar power seamlessly across the district and detect abnormal energy consumption. In Punggol Digital District, the buildings will be 30 per cent more energy-efficient than conventional commercial buildings, thanks to the sustainable design and smart optimisation enabled by the district’s open digital platform. Process: Sustainable districts can serve as test beds for urban systems innovation, enabling government agencies and industry partners to pilot a suite of complementary policies and actions to tackle greenhouse gas emissions. Take Punggol’s open digital platform, which will collect districtwide data through its network of sensors, including building data (to do with lifts, lighting and occupancy, for example) and environmental data (such as temperature and rainfall). These data sets will allow JTC to optimise resources in real time and fix issues before they become serious problems. The open digital platform’s digital twin technology will also provide an experimental environment for anyone in the district. It will allow industries and researchers to tap the open data to MAKING A DIFFERENCE Tengah and Punggol Digital District are in the vanguard of city-level eco-smartness, but there are ways for everyone to contribute, no matter where in Singapore you live. SP Group is helping its customers to do just that through the My Carbon Footprint and My Green Credits features on the SP Utilities app. These allow customers to track carbon emissions resulting from electricity, water and gas consumption, and match this with the purchase of an equivalent amount of green energy. With the right urban infrastructure and power of knowledge, it will be possible to achieve climate action goals at both the individual and national levels. stopinion@sph.com.sg • Hugh Lim is the executive director of the Centre for Liveable Cities (www.clc.gov.sg), under the Ministry of National Development.
