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. This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Services): This fee is reviewed annually. This is to recover the costs of billing and meter reading, data management, retail market systems as well as for market development initiatives. d) 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.

News Release SP DEVELOPS FUTURE ENERGY LEADERS THROUGH FIRST ENERGY MANAGERS PROGRAMME AND INDUSTRY SCHOLARSHIPS Singapore, 2 November 2018 – Singapore Institute of Power and Gas (SIPG), as the centralised training institute for the power and gas sectors, announced today the successful completion of its first Energy Managers Programme (EMP). The pioneer cohort of 19 energy sector professionals was recognised in a ceremony during Singapore International Energy Week 2018, witnessed by Dr Tan Wu Meng, Senior Parliamentary Secretary, Ministry of Trade and Industry and Ministry of Foreign Affairs. The programme, which is under the SkillsFuture Leadership Development Initiative, is designed to build a pipeline of strong leaders for the energy sector as they address issues and opportunities in today’s transforming and disruptive landscape. Building on its inaugural run, SIPG is opening its programme to participants from ASEAN utilities and other international companies in the energy value chain, curating a broader range of experiences, perspectives and real-world applications. Mr Peter Leong, Principal of SIPG, said, “We customised this programme to help energy industry managers hone their well-rounded leadership skills through blended learning in the classroom and field trips to companies in Singapore and overseas. They have personally benefitted from networking with peers from across the value chain. They have also gleaned insights on driving advancement and innovation amidst the rapid industry disruption, in order to serve all consumers better.” Spanning five months from February this year, the programme’s first participants were emerging leaders from generation companies and SP Group. Through workshops, dialogues with senior leaders from the energy sector and government, as well as a learning trip to China, the participants were exposed to pertinent challenges the industry faces, in Singapore and around the region. They also gained valuable insights from individual coaching sessions and working on action projects. Mr Neo Bing Hui, Senior Operations Engineer, YTL PowerSeraya Ltd, said, “The Energy Managers Programme (EMP) has helped broaden my views of the industry in general, providing a different perspective of how challenges can be viewed in the energy sector. After going through EMP, I have gleaned more insights on my leadership style and how I can effectively improve communication with my team mates. I am excited to start applying what I've learnt from this programme.” The pressing need to inspire the energy sector to groom the next generation of energy leaders is why the Energy Market Authority is supporting the programme. Its Chief Executive, Mr Ngiam Shih Chun, said: “For the energy sector to embrace new opportunities and challenges, there is a need to engage and develop tomorrow's energy leaders. They will need to be agile and adopt a growth mindset to lead their organisations forward. EMA supports SIPG in playing a crucial role in providing a programme to grow our future energy leaders.” Nurturing engineering talent In developing future engineering talent, SP Group also awarded two Energy-Industry Scholarships to students from institutions of higher learning – Ms Choo Wei Ming, 19, from Ngee Ann Polytechnic and Mr Muhammad Syahiran bin Jamal, 20, from Singapore Polytechnic.

GAS TRANSPORTATION TARIFFS (for Shippers with Natural Gas Distribution customers) (W.E.F. 1 Apr 26) 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 23 cents/mmBtu for PNG Injection Points or GSC of 4 cents/mmBtu for LNG Injection Points is imposed on PNG and LNG gas users respectively with effect from 1 Apr 26 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 1 537.20 2,432.36 2,969.56 1.59 + 23.0 Transmission Network 2 * 2,158.83 810.73 2,969.56 1.59 + 23.0 Transmission Network 2^ 1,637.32 1,332.24 2,969.56 1.59 + 23.0 b) LNG source Transmission Network 1 769.89 2,706.41 3,476.30 1.90 + 4.00 Transmission Network 2 1,470.60 2,005.70 3,476.30 1.90 + 4.00 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 1 585.55 2,651.27 3,236.82 1.73 + 25.1 Transmission Network 2 * 2,353.12 883.70 3,236.82 1.73 + 25.1 Transmission Network 2^ 1,784.68 1,452.14 3,236.82 1.73 + 25.1 b) LNG source Transmission Network 1 839.18 2,949.99 3,789.17 2.07 + 4.36 Transmission Network 2 1,602.95 2,186.21 3,789.17 2.07 + 4.36 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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Upholding our energy networks for 36 years and counting RELIABILITY Backed by 36 years of experience at SP Group, veteran engineer Ang Seng Kok has been part of a gamut of iconic projects and meticulous operations that have established Singapore’s world-class power grid. Currently the General Manager of Projects at SP PowerGrid, he oversees the implementation of Electricity and Gas projects such as installation and renewal of electricity equipment and cables, substation modification works, installation of gas transmission and distribution pipelines, and diversion works. “A major project we’re working on is the transmission and distribution switchgear and cable renewal works at Admiralty Road West 230kV substation. The equipment has reached the end of its service life and replacement works are needed to maintain overall network reliability.” He vividly remembers the intricate details of his career at SP as well PUB prior to corporation. Seng Kok at Telok Blangah depot during his first posting to the Operations and Maintenance Central section in 1988. In 1985, Seng Kok started with the Operations and Maintenance Central section. He obtained his switching certificate to operate 22kV networks and was trained to conduct equipment maintenance, fault repair and cable diversion. He recalled his initial years when he benefitted from overseas exposure. “One of my first postings at SP Group (then PUB) was at the Public Lighting section. My team was in charge of installing and maintaining street lighting for public roads for the entire island. In 1994, I was sent to Holland for a two-week lighting course to learn about the best lighting designs for road users so as to provide safe and comfortable vision for road users at night." Seng Kok (fourth from left) with his course mates during the lighting course in Europe, in 1994. An incident that left the deepest impression was when he was with the Distribution Control & Customer Service section. A major power outage occurred in 2004 at around 10pm and one-third of the customers were affected. “As head of the section, I was on my usual round-the-clock standby in case of any network disruption. I recall sprinting down the staircase from the 13th floor of my apartment as the lift stopped working. I had to brave the darkness and drove to the control centre safely with no operating traffic lights and streetlights while staying on the phone line to provide situation updates!” Seng Kok with the Electricity Service Centre crew when he was with the Distribution Control & Customer Service section in 2008. In 2016, Seng Kok assumed responsibilities in Procurement which he felt was his “most interesting stint” as he held his first non-engineering role. “It was an eye-opening experience carrying out factory audits before awarding tenders to manufacturers. We had to ensure adequate manufacturing capability, sound processes for quality control and assurance are in place and workers are well trained. Seng Kok (centre) with engineers from SP PowerGrid at a substation. The 61-year-old added, “After doing my tour of duty across different teams, I am back to where I first began. It has come full circle for me! However, the way we operate has changed tremendously over the years, with energy transformation, digitalisation and higher customer expectations. To be effective in what we do, it’s important to stay agile and keep up to date with best practices and technology.” 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
