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.

Media Release Electricity Tariff Revision For The Period 1 January to 31 March 2022 Singapore, 30 December 2021 – For the period from 1 January to 31 March 2022, electricity tariff (before 7% GST) will increase by an average of 5.6% or 1.33 cents per kWh compared with the previous quarter. The increase this quarter is due to higher fuel costs. Around 95% of Singapore’s electricity is generated using imported natural gas at prices indexed to oil prices. Over the past few months, a confluence of recovering economic activity, severe weather events, and a series of gas production outages have sent global energy market prices significantly higher. These factors have raised electricity prices in many markets. 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 24.11 to 25.44 cents per kWh for 1 January to 31 March 2022. The average monthly electricity bill for families living in HDB four- room flats will increase by $4.70 (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. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg 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.

SP building undersea transmission cable tunnel It will connect Jurong Island to the mainland By RONNIE LIM ronnie@sph.com.sg ONE year after starting construction of Singapore’s $2 billion next-generation power network, Singapore Power (SP) is now following up by building a crucial new undersea transmission cable tunnel connecting Jurong Island (JI) to the mainland to export electricity from new power plants there. Penta-Ocean Construction, which was awarded the latest contract in October, started work last month on the 5.2 km JI-Pioneer (Road) cable tunnel under the West Jurong Channel, Singapore Power disclosed in its just-released 2012/13 annual report. No project cost was mentioned because of contractual reasons. “Cost-wise, it is a fraction of the $2 billion mainland tunnel project. But the undersea tunnel is not a small project, and it is also more challenging as it goes deeper,” said SP’s CEO, Wong Kim Yin, in an interview. Expected to be around 45 metres to 80 metres deep, the undersea cable tunnel is “planned in conjunction with the (next-generation) 400kV West Jurong Island substation and will accommodate up to 10 circuits” from JI to the mainland, SP added. It will also house Singapore’s next-generation 400 kV transmission cables (replacing current 230kV ones) which have greater capacity to handle the volume of electricity being generated and transmitted here. SP had earlier carried out both preliminary and detailed soil investigations, as the tunnel will be built through Jurong sedimentary formation. The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings by gencos including Keppel Merlimau Cogen, Sembcorp Cogen, Tuas Power’s multi-utilities complex and newcomer PacificLight Power. “By 2019, transmission load in south-western Singapore is expected to increase by 62.5 per cent,” SP said, explaining the need to expand the transmission cable network in that area, which includes Jurong Island and Tuas (where the new port will also be built). Timing-wise, it will also tie in with the expected completion of the mega $2 billion cross-island tunnel The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings. project on the mainland. Comprising two ultra-deep, extra-high voltage power transmission tunnels running 16.5 km east-west and 18.5 km north-south, the tunnels are expected to be completed in Q2, 2017 and Q2, 2018 respectively. Tunnelling proper of the two is set to start early next year, following the completion of the upper and lower access shafts this year. In its annual report, SP said that it is leveraging cutting-edge technology and investing in network infrastructure to support key industries and economic and social developments. For instance, it said that to cater for future growth and development of petrochemical industries on JI, development of Tembusu 230kV and 400kV West Jurong Island substations is progressing. Rangoon 400kV substation is also set to be completed by this year-end to cater to power demand growth in central Singapore. On the gas front, subsidiary PowerGas also supported the start-up of the Singapore LNG terminal in May this year by laying pipelines connecting SLNG to new transmission customers.
