GAS TRANSPORTATION TARIFFS (for Shippers with Natural Gas Distribution customers) (W.E.F. 1 Apr 24) 1 Introduction 1.1 Under the Gas Network Code, PowerGas is the Gas Transporter and is responsible for maintaining the reliability and safety of the gas transportation network in Singapore. PowerGas’ transportation business is regulated by the Energy Market Authority (EMA). The transportation tariffs levied by PowerGas are approved by the EMA. 1.2 The transportation tariffs are levied on Shippers. Shippers pay transmission as well as distribution charges as part of the distribution tariff for transportation of natural gas to distribution-level end-users. This is to reflect the cost of transporting gas through both the transmission and distribution networks. 1.3 End-user transportation charges imposed by Shippers are commercial arrangements between the Shippers and their end-users. 2 Natural Gas Distribution Tariffs 2.1 Arising from EMA’s notification to the industry dated 21 March 2024, a GSC of 20 cents/mmBtu for PNG Injection Points or GSC of 2 cents/mmBtu for LNG Injection Points is imposed on PNG and LNG gas users respectively with effect from 1 Apr 24 to recover the cost associated with Strategic Capacity (as defined in EMA's Policy Paper issued to the industry dated 30 Sep 2019). The Transporter will collect the GSC from all Shippers as an agent for and on behalf of SLNG. The GSC will be reviewed from time to time as directed by EMA and will be included as an uplift in the transmission usage charge. 2.2 The Distribution tariff is made up of two components (i.e. a Transmission Charge component and a Distribution Charge component). 3 Transmission Charging Structure 3.1 Transmission charges consist of capacity and usage charges. Shippers book capacity with PowerGas to transport gas from designated injection points to off-take points. Shippers pay entry and exit charges based on their respective booked capacity. In addition, uniform usage charge is levied on the volume of gas transported. Details of the transmission charge components are shown in Table 1 of the Appendix. 3.2 Shippers will have to pay Overrun Charges in the event they off-take gas above their booked capacity. These Overrun Charges are necessary to encourage the efficient use of the gas network. There are two types of Overrun Charges: • Authorised Capacity Overrun Charge: If a Shipper applies for additional capacity above the booked capacity (i.e. capacity overrun), the Authorised Capacity Overrun Charge, equivalent to 1.25 times the Transmission Capacity Charge rate, shall be applied on that additional capacity. • Unauthorised Capacity Overrun Charge: If a Shipper does not apply for Authorised Capacity Overrun for utilisation of additional capacity above the booked capacity, it will pay 2 times the Transmission Capacity Charge rate for that additional capacity utilised. 4 Distribution Charging Structure The Distribution Charge component is a usage-based charge in $/MMBtu. The Distribution Network is segregated into two service areas as follows: • The Jurong Island, Jurong and Tuas (“JIT”) area 2 • Outside the JIT area As the cost to serve the area outside JIT is higher than the JIT area, this results in a higher usage charge for the former. The Distribution Charges are shown in Table 2 of the Appendix. 5 Appendix – Table of Charges Table 1: Transmission Charges for Shippers with Natural Gas Distribution Customers (Exclusive of GST) Entry capacity charge ($/MMBtu/hr) Per Annum (a) Exit capacity charge ($/MMBtu/hr) Per Annum (b) Transmission capacity charge ($/MMBtu/hr) Per Annum (a) + (b) Transmission usage charge (comprising non-GSC and GSC) (¢/MMBtu) a) PNG source Transmission Network 1 970.19 1,718.49 2,688.68 1.40 + 20.0 Transmission Network 2 * 1,616.07 1,072.62 2,688.69 1.40 + 20.0 Transmission Network 2^ 1,240.93 1,447.75 2,688.68 1.40 + 20.0 b) LNG source Transmission Network 1 1,165.26 2,017.34 3,182.60 1.71 + 2.00 Transmission Network 2 1,185.71 1,996.89 3,182.60 1.71 + 2.00 Table 1a: Transmission Charges for Shippers with Natural Gas Distribution Customers (Inclusive of 9% GST) + Entry capacity charge ($/MMBtu/hr) Per Annum (a) Exit capacity charge ($/MMBtu/hr) Per Annum (b) Transmission capacity charge ($/MMBtu/hr) Per Annum (a) + (b) Transmission usage charge (comprising non-GSC and GSC) (¢/MMBtu) a) PNG source Transmission Network 1 1,057.51 1,873.15 2,930.66 1.53 + 21.8 Transmission Network 2 * 1,761.52 1,169.16 2,930.67 1.53 + 21.8 Transmission Network 2^ 1,352.61 1,578.05 2,930.66 1.53 + 21.8 b) LNG source Transmission Network 1 1,270.13 2,198.90 3,469.03 1.86 + 2.18 Transmission Network 2 1,292.42 2,176.61 3,469.03 1.86 + 2.18 Notes: 1) Transmission Network 1 refers to the natural gas transmission network conveying both piped natural gas and regasified LNG from West Natuna (Indonesia) and the LNG Terminal.

Cents/kWh MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 OCTOBER TO 31 DECEMBER 2020 Singapore, 30 September 2020 – For the period from 1 October to 31 December 2020, electricity tariff (before 7% GST) will increase by an average of 1.83 cents per kWh compared with the previous quarter. The revised tariff and that of the preceding quarter are the lowest in the last three years. The increase this quarter is due to higher energy costs, which forms a major component of the electricity tariff and is paid to power generation companies. The remaining components of the tariff, consisting of network costs and market support services fees to SP Group and Market Administration and Power System Operation Fee to Energy Market Company and Power System Operator, remain unchanged (Appendix 1: Breakdown of Electricity Tariff). For households, the electricity tariff (before 7% GST) will increase from 19.60 to 21.43 cents per kWh for 1 October to 31 December 2020. The average monthly electricity bill for families living in fourroom HDB flats will increase by $7.01 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic customers). 30.00 Quarterly Household Electricity Tariff* 25.00 20.00 23.85 22.79 24.22 23.43 24.24 23.02 19.60 21.43 15.00 10.00 5.00 0.00 Jan - Mar 19 Apr - Jun 19 Jul - Sep 19 Oct - Dec 19 Jan - Mar 20 Apr - Jun 20 Jul - Sep 20 Oct - Dec 20 *before 7% GST The electricity tariffs are reviewed quarterly based on guidelines set by the Energy Market Authority (EMA), the electricity industry regulator. The tariffs shown in Appendix 2 have been approved by the EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) 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. b) Network costs (paid to SP PowerAssets): This fee is reviewed annually.

Media Release Electricity Tariff Revision for the Period 1 July to 30 September 2025 SINGAPORE, 30 June 2025 – For the period from 1 July to 30 September 2025, the electricity tariffs (before GST) for households will decrease by 2.3% or 0.65 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 $2.36 (before GST). The overall electricity tariff (before GST), including tariffs for non-households, will decrease by an average of 2.4% or 0.65 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 energy cost component of the electricity tariffs for each quarter is set using the average natural gas prices in the first two and a half months in the preceding quarter. The electricity tariffs may fluctuate quarter to quarter due to volatile global fuel prices driven by geopolitical factors such as the ongoing conflicts in the Middle East. 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 and retail market systems. 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.   Q3 2025 TARIFF FOR HOUSEHOLDS (before 9% GST) Appendix 2 ELECTRICITY TARIFFS FROM 1 JULY 2025 Appendix 3 AVERAGE MONTHLY ELECTRICITY BILLS FOR HOUSEHOLDS TARIFF WEF 1 JULY 2025 (before GST)
