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 Shaping the evolution of electricity meters in the past 25 years RELIABILITY Vice President of SP Services’ Metering Branch Razali Bin Mohd. “If my coral dies, you pay”, is a customer’s comment that 51-year-old Razali Bin Mohd recalls in an unforgettable experience during his earlier days as an engineer. His team was carrying out electricity meter replacement works then. In this unique situation, when the customer was informed that the power supply will be temporarily disrupted during the replacement, she requested for a mobile electrical generator to keep her coral tanks maintained at four degrees Celsius during the servicing period. Handling a multitude of customer requests, is part and parcel of stakeholder management in Razali’s job at SP Group (SP). Over his 25 years with SP, the Vice President of SP Services’ Metering Branch has seen the evolution of analogue electricity meters manually read by meter readers to smart meters that can now be monitored remotely. As of May 2022, Razali and his team have deployed over 650,000 smart electricity meters islandwide. In the next few years, all 1.4 million residential households in Singapore will be equipped with smart meters. “I cherish this experience the most as we took great lengths to incept this idea and eventually see it come to fruition. As this project had a nation-wide impact, I remembered we went to the Parliament to present our plans to the Mayors, and convinced the relevant agencies to support our deployment plan.” Razali now has another ambitious task ahead of him. Besides rolling out smart electricity meters nationwide, his team also won the contract for Singapore’s first large-scale smart water meter programme for PUB in Apr 2021. Over the next 15 years, they will be developing the metering system, enhancing the wireless communications network, deploying, operating and maintaining over 300,000 smart water meters. “We faced intense competition against strong contenders and various challenges during the tender process. Our strong teamwork and expertise in smart electricity meter deployment has enabled us to secure this strategic partnership. The late-night calls with counterparts from different parts of the world were all worth it!” Interestingly, his career options after graduating as an electrical engineering graduate from Nanyang Technological University were between a cadet pilot at a leading airline and an engineer at SP. He received SP’s letter of offer on the day of his final round of interview for the cadet pilot position. “I just went with my gut feel and I am convinced now looking back, it was meant to be.” he recalled fondly.   Razali with his colleagues from the metering team at the old St James District Office in 2011. Back in the late 90s, Razali’s key responsibilities included working with contractors to install and maintain meters for residential and commercial customers, procure new meters, handle project tenders and manage customer feedback.  The implementation of smart electricity meters in Singapore has been the highlight of his career. Razali with colleagues from SP Services and SP Digital on an overseas trip to Itron’s office in San Francisco, to adopt best practices from the implementation of the US’ smart meter programme. Before the opening of Singapore’s electricity retail market in 2014, Razali and his team travelled to San Francisco and Melbourne to learn how these cities deployed smart meters successfully. “The study trip shortened our learning curve and prevented potential pitfalls.” SP is one of the first few utility companies in the world that has separated its communication network card from the meter. In other parts of the world, communication modules are integrated within the meters. Hence, if the communication part fails, the entire meter must be replaced. In Singapore, the decision was to adopt a “modular” structure for parts to be replaced separately if they are faulty. This will not only save cost, but also eliminate supply interruption and reduce inconvenience to the customers. CEO of SP Services Law Chin Ho (sixth from left) and Razali with the SP Services team that won the contract for Singapore’s first large-scale smart water meter programme for PUB in Apr 2021. Razali is thankful for all the growth opportunities at SP and is committed to continue rising to the challenges in the evolving energy industry. “I wake up every day looking forward to the next challenge at work. I am thankful for the wonderful team support. We are constantly innovating and finding solutions to problems. It gives me a huge sense of job satisfaction!” Volunteering trip with SP colleagues in Cambodia in 2015. In his free time, Razali enjoys travelling for nature walks, trekking, snorkelling, and exploring other types of land and sea activities. He also finds meaning in organising charity trips to children’s orphanages in Thailand, Cambodia and Indonesia and has even rallied his colleagues to join him in distributing essential items for these vulnerable communities. With borders reopening, Razali hopes to revive this initiative very soon!
