Media Release Electricity Tariff Revision for the Period 1 October to 31 December 2024 Singapore, 30 September 2024 – For the period from 1 October to 31 December 2024, the electricity tariff (before GST) for households will decrease by 2.6% or 0.78 cent per kWh compared with the previous quarter due to lower energy costs. The average monthly electricity bill for families living in HDB four-room flats will decrease by $3.00 (before GST). Electricity tariffs (before GST), including tariffs for non-households, will decrease by an average of 2.5% or 0.70 cent per kWh compared with the previous quarter. SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The electricity tariffs may fluctuate quarter to quarter due to volatile global fuel prices. Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the electricity tariffs approved by EMA, and Appendix 3 for the average monthly electricity bill for households. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.   Q4 2024 TARIFF FOR HOUSEHOLDS (before 9% GST) Appendix 2 ELECTRICITY TARIFFS FROM 1 OCTOBER 2024 Appendix 3 AVERAGE MONTHLY ELECTRICITY BILLS FOR HOUSEHOLDS TARIFF WEF 1 OCTOBER 2024 (before GST)

Media Release Temasek Cares Extends Its 'Stay Prepared' Initiative To Help Build Community Resilience In Singapore Singapore, Monday 5 May 2014 Temasek Cares is partnering Singapore Power and Singapore Post to extend its "Stay Prepared" initiative by encouraging individuals and families to be prepared for emergencies. Conceived by Temasek Cares with Singapore Power to prompt individuals and families to be prepared well ahead of any emergencies, a total of 1.2 million "Stay Prepared" Starter Kits will be distributed by Singapore Power and Singapore Post to all households in Singapore from 6 to 12 May 2014. Each "Stay Prepared" Starter Kit contains three 3M™ N95 face masks, instructions on how to wear the masks and emergency contact numbers. About 17,000 Starter Kits will also be delivered to charity homes, and another 300,000 Kits have been prepared on standby for needy families in case of severe haze or flu pandemic emergencies. Mr Richard Magnus, Chairman of Temasek Cares, said, “Singapore is a safe city. However, unforeseen events may adversely impact us and our community from time to time. All of us – individuals, families, companies – have to be prepared. For this reason, Temasek Cares wants to help build the resilience of our community, through its "Stay Prepared" initiative. “Temasek Cares is very pleased to partner Singapore Power and Singapore Post for this initiative to provide "Stay Prepared" Starter Kits to every household in Singapore. The Starter Kit includes three N95 masks so that each household can have an initial stock in case of a flu pandemic or severe haze from the forest fires in the region. We hope the Starter Kits will prompt individuals and families to develop their own emergency plans. The Starter Kit with the emergency contact numbers and the N95 masks can be useful additions to their family or personal emergency grab bags.” Mr Magnus added, “The Starter Kits programme is a significant step to fulfill Temasek Cares‟ vision of a resilient Singapore community – one that is ready for the unexpected, responds effectively to crises and recovers quickly from adversity. We will continue to come alongside people and partners in Singapore to create greater awareness of additional ways to be prepared. We believe such community initiatives are a useful way to complement national and individual efforts to keep Singapore safe.” Tan Sri Mohd Hassan Marican, Chairman of Singapore Power, said, “At Singapore Power, it is mission critical to respond to emergencies swiftly, safely and effectively. This readiness enables us to power every household and business in Singapore with world-class reliability, round the clock. We would like to encourage emergency preparedness among the community, so that it becomes second nature to everyone.” Tan Sri Hassan added, “We have mobilised our meter readers and technicians to distribute the "Stay Prepared" Starter Kits. We are running a call centre to address public queries on this effort. In addition, our staff volunteers will be distributing 17,000 starter kits to more than 140 charity homes for the elderly, disabled and other residential facilities . We would like to touch all facets of society in this outreach.” Mr Lim Ho Kee, Chairman of Singapore Post said: “We are happy to be part of this nationwide community effort to help Singapore households stay prepared. Over the next few days, some 1,200 postmen and postwomen will distribute the "Stay Prepared" Starter Kits to every HDB and high-rise household. As a responsible and trusted national postal service provider, SingPost remains committed to deploy our last mile delivery capability and resources to help with such meaningful initiatives.” Singapore Power has set up a hotline where members of the public can get information about the delivery of the "Stay Prepared" Starter Kits. The delivery hotline (Tel: 1800-738-2000) will be in operation from Monday 5 May 2014, to Saturday 24 May 2014, from 8.00 am to 8.00pm daily. If the "Stay Prepared" Starter Kit cannot be delivered to a postal address, residents will receive a delivery advice with information on where they can collect their Starter Kits. The "Stay Prepared" Starter Kits programme and the umbrella "Stay Prepared" initiative are backed by the Temasek Emergency Preparedness Fund, which was established by Temasek Holdings with an endowment of S$40m in March 2014, as part of its 40th anniversary community initiative.

The generator carried some 2,000 litres of diesel, enough to power up a housing estate for around eight hours, and up to 40 metres of cable to hook up to a low-voltage (LV) board, which distributes electricity. “We need to always be prepared to provide temporary power,” says Mr Mohamed Nasir bin Mohamed Ismail, 42, a technical officer who is part of the unit. Readiness is key for the Mobile Generator Unit. This begins at 7.30am with a daily “warm up”, conducted by the 10 men on the morning shift. During the one-hour ritual, all the operational mobile generators – the larger ones mounted on fourteen 30-ft trailers, and the smaller ones on seven 20-ft lorries – are started and tested to ensure they are ready to be deployed. The team members also conduct cable insulation tests and checks on their toolboxes and personal protection gear. This enables them to act swiftly and safely, in the event of an electricity disruption. The men, who work on three shifts round the clock, are deployed by SP Group’s Electricity Service Centre in teams of three – a leader, an assistant, and a driver. Mr Nasir, the leader of his team, has been with SP for 21 years, joining right after he completed his National Service in 1998. He studied mechanical engineering at the ITE and plays the role of synchroniser, ensuring that the voltage and frequency of the mobile generator matches that of the grid network. Mr Nasir, who has both a Class 4 and Class 5 driving license, doubles up as a driver, and says navigating these massive vehicles is an exercise that requires both practice and courage. The trailer-mounted mobile generators cannot travel through tunnels, including those on expressways like the MCE, CTE or KPE. The 60km/h speed limit also keeps them in the slowest lanes most of the time. The trailer-mounted generators are part of a fleet of 22 vehicles of different sizes and capacities used for power restoration. “You need to know the quickest alternative route around traffic or restrictions. Outage in Ang Mo Kio and leaving from Pasir Panjang? Alexandra, Farrer, Adam, Braddell, then join the CTE after the tunnel,” Mr Nasir rattles off. The narrow roads in some estates and parked vehicles can also pose problems for the 13 metres by 2.6 metres by 4.3 metres trailers, and it is up to the two men with the driver to recce for a spot to hunker down – which must also be close enough to an electrical room to hook up. While Singapore enjoys one of the lowest occurrences of outages in the world, it is gratifying to be a part of a team that helps “get the lights back on" if supply is disrupted, Mr Nasir says. “We are usually greeted by frustrated faces when we arrive, so seeing them happy again makes us very happy,” he quipped. — 1 May 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing

Media Release Electricity Tariff Revision for the Period 1 July to 30 September 2022 Singapore, 30 June 2022 – For the period from 1 July to 30 September 2022, electricity tariff (before 7% GST) will increase by an average of 8.1% or 2.21 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost driven by rising global gas and oil prices exacerbated by the conflict in Ukraine. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff. For households, the electricity tariff (before 7% GST) will increase from 27.94 to 30.17 cents per kWh for 1 July to 30 September 2022. The average monthly electricity bill for families living in HDB four-room flats will increase by $8.25 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic consumers). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The tariffs shown in Appendix 2 have been approved by EMA. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

General Information 1.1 Purpose of this Document PowerGas is licensed by the Energy Market Authority (“Authority”) to be the Gas Transporter (“Transporter”) which owns, operates, and maintains the piped gas network in Singapore. SP PowerGrid (“SPPG”) is licensed by the Authority to be the Gas Transporter Agent to operate and maintain the piped gas network in Singapore on behalf of PowerGas. SPPG’s gas business is to plan, design, operate and maintain gas network assets in a manner that supports the delivery of safe, reliable, efficient, and quality services to customers. Under the Gas Transporter Licence, the Gas Transporter has to develop separate fees and charges for separate gas transportation services such as connection services and transportation services. This document sets out the connection policy and procedure for Natural Gas supply. 1.2 Singapore Gas Transportation System PowerGas owns an extensive gas transmission and distribution network throughout Singapore. The network is generally buried underground and transports natural gas to the western and northern parts of Singapore, and town gas to the whole of Singapore. The gas assets comprise the transmission network (operating at higher pressures), which forms the main reticulation backbone and the distribution network (operating at lower pressures). • Town gas is manufactured in Senoko Gasworks and delivered to approximately 900,000 customers in Singapore. The customers are made up of industrial, commercial, and residential gas users. Residential customers consist mainly of gas users from HDB, condominiums and landed premises. The town gas transmission network operates at 3 barg whereas the distribution network operates at pressure regimes ranging from 1 kPa to 50 kPa. Natural gas is supplied to about 200 customers and is imported from four sources (two submarine pipelines from Indonesia, one submarine pipeline from Malaysia and internationally through the Liquefied Natural Gas Terminal). Under the Gas Network Code, Gas Shippers/Retailers represent the customers that are connected to the natural gas networks. These natural gas customers are typically commercial or industrial and include all power stations. The natural gas transmission network operates mainly at two pressure regimes, 28 barg and 40 barg, and the distribution network operates at pressure regimes ranging from 3 barg to 6 barg.

Charges 4.1 Connection Policy The cost to connect a customer’s gas installation or gas fitting to the Transporter’s gas pipeline network varies from case-to-case, due to the proximity of the customer’s location and the cost of the materials and services required for the gas connection. Where possible, the Transporter will envisage to propose the most cost-effective connection to the applicant. 4.2 Connection Charge The connection charge payable for all gas connection applications is the sum of the project cost less the deductible cost, subject to a minimum connection charge of zero. The description of each of the cost components are shown below. (1) Project cost All costs related to the provision of gas connection from the Transporter’s gas pipeline network to the GSIV, including the Meter Installation (where applicable). (2) Deductible cost The Transporter’s investment value based on the committed gas demand from the applicant for the new gas connection. For distribution connections, the investment value is derived based on the net present value of the 5-Year revenue of the average consumption for each consumption category (see Appendix 8). For transmission connections, the connection charges are calculated individually on a case-bycase basis. In addition, a Last Mile Connection Charge (“LMCC”) will be levied to recover the cost of the “last mile” connection of the gas installation to the GSIV from the applicant. The natural gas transmission/distribution connection deductible cost, LMCC and unit rates used in the determination of the transmission/distribution pipeline estimated capital investment shall be reviewed and adjusted when deemed necessary by the Transporter. The Transporter reserves the right to review the connection charge paid for any new connection and seek reimbursement for the first 5 years under-recovered revenue from the Shipper/Retailer if the actual gas consumption after 5 years of operation is more than 10% below the projected gas demand declared during application. Natural Gas Connection Policy and Procedure Updated 1 Apr 24 Page 11 5.
