GAS TRANSPORTATION TARIFFS (for Shippers with customers off-taking natural gas at high pressure) (W.E.F. 1 Apr 25) 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 PowerGas charges transportation tariffs for the transport of gas through its network. PowerGas’ transportation tariffs are levied on Shippers and not the end-users. End-users’ transportation charges imposed by Shippers are commercial arrangements between both parties. 2 Natural Gas Transmission Tariffs 2.1 There are two gas transmission networks, namely Transmission Network 1 and Transmission Network 2. 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. Transmission Network 2 is the natural gas transmission network conveying both piped natural gas and regasified LNG from South Sumatra (Indonesia), Attap Valley (Malaysia) and the LNG Terminal. 2.2 Transmission tariffs consist of capacity and usage charges (refer to Section 3 below for details). These charges are applicable to Shippers off-taking gas at high pressure. The same charging structure also applies to Shippers with Small Transmission Customers (i.e. with load less than or equal to 5 bbtud). 3 Transmission Charging Structure 3.1 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, a usage charge is levied on the volume of gas transported. 3.2 Arising from EMA’s notification to the industry dated 21 March 2024, a GSC of 22 cents/mmBtu for PNG Injection Points or GSC of 3 cents/mmBtu for LNG Injection Points is imposed on PNG and LNG gas users respectively with effect from 1 Apr 25 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 usage charge. Details of the transmission charges are shown in Table 1 of the Appendix. 3.3 These transmission charges do not include specific cost items which need to be determined on a case-by-case basis for inclusion into the final transmission charges. 3.4 For Shippers with Small Transmission Customers (i.e. requiring gas at high pressure, but with load of less than or equal to 5 bbtud), the transportation charges as shown in Table 2 of the appendix shall apply. 3.5 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. 2 • 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 Appendix – Table of Charges Transmission Network 1 (locational) Transmission Network 2 (locational) Table 1: Transmission Charges (Exclusive of GST) Entry Capacity Charge per annum ($/MMBtu/hr) Exit Capacity Charge per annum ($/MMBtu/hr/km) Transmission Usage Charge ($/MMBtu) 891.91 57.94 0.0087 1,503.65 (Attap Valley Injection Point) 1,093.61 (Sakra Injection Point) 43.07 0.0132 New Pipeline – utilised 276.51 276.51* 0.0034 New Pipeline – excess 232.31 232.31* 0.0041 GSC for PNG Injection Point N.A.

Media Release Singapore’s largest industrial district cooling system begins operations to support STMicroelectronics’ decarbonisation strategy Designed, built, owned and operated by a joint venture between SP Group and Daikin Airconditioning (Singapore), the innovative district cooling system will significantly improve the environmental performance of ST’s high-volume semiconductor manufacturing site in Singapore New system expected to reduce carbon emissions by 120,000 tonnes per year, cooling-related electricity costs by 20 percent each year, and repurposing over half a million cubic meters of water consumption per year 21 October 2025, Geneva, Switzerland, and Singapore – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, and SP Group (SP), a leading utilities group in the Asia Pacific and Singapore’s national grid operator, have commenced operations for Singapore’s largest industrial district cooling system at STMicroelectronics’ (ST) Ang Mo Kio TechnoPark. The event was inaugurated by Ms. Low Yen Ling, Senior Minister of State, Ministry of Trade and Industry and Ministry of Culture, Community and Youth. The system is expected to reduce carbon emissions by up to 120,000 tonnes per year and enable 20 per cent savings on cooling-related electricity consumption. It will also repurpose over half a million cubic meters of water each year by using reject reverse osmosis water, previously used in ST Cooling Towers, to support the new district cooling operations.  This marks ST’s first use of district cooling at a manufacturing facility and will strengthen ST’s commitment to be carbon neutral by 2027. “The deployment of Singapore’s largest industrial district cooling system at our Ang Mo Kio TechnoPark demonstrates our commitment to pioneering energy-efficient solutions that reduce carbon emissions and conserve resources. This achievement strengthens our partnership with Singapore in advancing its national sustainability goals, said Rajita D’Souza, President of Human Resources and Corporate Social Responsibility at STMicroelectronics. “By integrating advanced technologies like the district cooling system, we are driving a smarter, greener future — showcasing how industry leadership and environmental stewardship align to create lasting value for our business, communities, and the planet.” “SP Group’s strategic partnership with STMicroelectronics marks a pivotal milestone in our nation’s transition towards a low-carbon future. This project showcases how collaborative innovation can transform urban infrastructure to deliver sustainable, energy-efficient solutions. District cooling will continue to play a vital role in Singapore’s net-zero ambitions, enabling carbon emissions reduction and enhancing energy resilience across industrial and urban developments,” said Mr Stanley Huang, SP’s Group Chief Executive Officer.  Technical information about the district cooling system  Designed, built, owned, and operated by a joint venture between SP and Daikin Airconditioning (Singapore), the system has an installed capacity of up to 36,000 refrigeration tonnes (RT). It delivers continuous chilled water to cool both manufacturing and office spaces via a centralised closed-loop pipe network replacing individual chillers in each building. The total area served by the system is approximately 90,000 square metres. Chillers in series counterflow configuration reduce the energy required to cool the water. This ensures an efficient and reliable 24/7 operation, with remote monitoring capabilities augmenting the operations team on site to come. “This partnership with SP reflects Daikin’s commitment to delivering advanced, energy-efficient solutions that go beyond immediate operational needs. Our goal is to contribute to a more sustainable built environment, where technology plays a key role in enhancing resilience, reducing environmental impact, and supporting Singapore’s long-term climate ambitions,” said Mr Chua Ban Hong, Managing Director at Daikin Airconditioning (Singapore). Additionally, the new installations free up around 4,000 square metres of space at Ang Mo Kio TechnoPark, which will enable ST to install other equipment contributing to environmental impact mitigation. This includes perfluorocarbon (PFC) abatement equipment, with near-future plans for additional water reclamation systems and volatile organic compounds (VOC) abatement as part of its ongoing sustainability efforts. The project achieved over 2 million accident-free man hours, underscoring the commitment to safety during construction. The district cooling plant has been awarded the Green Mark Platinum Super Low Energy certification by the Building and Construction Authority for its exceptional energy efficiency and sustainable design. Incorporating whole-life carbon assessments during design and construction of the plant also enabled a reduction of about 44 percent in embodied carbon compared to industrial building benchmarks, achieved through optimised material choices and system design to further lower the plant’s carbon footprint. Further collaboration between STMicroelectronics and SP Group To accelerate its decarbonisation roadmap, ST has also partnered with SP to upgrade the cooling system at its Toa Payoh site. Under a 20-year chilled-water-as-a-service agreement, SP will design, build, operate, and maintain a new high-efficiency chiller system, scheduled for completion by December 2025. The system will improve energy efficiency and aims to reduce carbon emissions by approximately 2,140 tonnes annually. In addition to sustainable cooling solutions, ST and SP are implementing a range of sustainable technologies across ST’s Ang Mo Kio and Toa Payoh campuses. This includes the deployment of the energy management information system (EMIS), comprising 2,400 smart electricity meters and multi-utility sensors. With SP’s smart metering infrastructure in place, ST can monitor its overall energy consumption – enabling data-driven decisions that enhance efficiency and sustainability. SP has also implemented smart water meters that track water inflow to five of ST’s buildings. This provides ST with an accurate view of its water consumption, allowing the organisation to enhance its critical wafer fabrication operations by ensuring greater water efficiency. Together, the partnership delivers on a shared vision for a smarter, cleaner energy future through integrated digitalisation and decarbonisation at scale.

News Release SP GROUP PARTNERS CHEVRON TO OFFER ELECTRIC VEHICLE CHARGING AT SELECTED CALTEX SERVICE STATIONS Singapore, 22 March 2021 – SP Group (SP) and Chevron Singapore Pte. Ltd., which markets the Caltex TM brand, today announced a partnership to offer fast electric vehicle (EV) charging at selected Caltex service stations, delivering on-the-go convenience to electric vehicle motorists. To be located at four of Caltex’s service stations across Singapore, the initial batch of chargers will be strategically located across the Caltex network, at Chong Pang (North), Changi (East), Jurong Spring (West) and Dunearn (Central). These Caltex service stations will be equipped with 50kW direct current (DC) fast chargers that can charge up an EV in 30 minutes, versus a few hours required by the more commonly available alternating current (AC) chargers. Three service stations will each be equipped with one 50kW direct current (DC) fast charger. The fourth, at Changi, will have two 50kW DC charging points that are designed to allow a compatible car to charge up to a speed of 100kW, provided only one car is utilising the charging points. (Refer to the annex for the addresses of this first batch of service stations.) SP and Caltex will study EV charging usage patterns and behaviour at the stations to refine and enhance accessibility and utilisation, and plan for more charging points and locations. Group Chief Executive Officer of SP, Mr. Stanley Huang, said, “We are pleased to partner Caltex in our first collaboration with a fuels and lubricants retailer. This gives EV drivers greater convenience as it accelerates the accessibility of charging locations that are incorporated in our daily activities. Our aim is to build Singapore’s largest public EV charging network and expand our integrated green mobility solutions to meet the evolving needs and sustainability goals of businesses and individuals.” "Chevron is excited to partner with SP Group to provide EV chargers at selected Caltex stations in Singapore. It is Chevron’s goal to deliver affordable, reliable, and ever-cleaner energy that enables human progress," said Mr. Law Tat Win, Chevron Singapore Country Chairman. "We 1 endeavour to continually test, learn and explore how to enhance our product and service offerings for our Singapore customers at our Caltex stations.” This SP and Caltex partnership will better serve drivers choosing electric vehicles and help achieve a lower-carbon future for Singapore. This includes Caltex’s existing commercial customers who plan to electrify their fleets. Both companies will continue to explore initiatives to meet the EV needs for private ownership and commercial use. The chargers will be installed by the second quarter of 2021 and will be incorporated on the SP Utilities mobile app for ease of use. The SP Utilities mobile app allows EV drivers to search for the availability of the nearest charging points, receive real-time updates on their charging sessions and make direct, cashless payment. -Ends- 2 About SP Group SP Group is a leading utilities group in the Asia Pacific, enabling a low-carbon, smart energy future for its customers.

Media Release New Residential Demand Response Pilot to Empower Households to Reduce Electricity Consumption during Demand Peaks The Energy Market Authority (EMA) and SP Group (SP) will pilot a Residential Demand Response (R-DR) programme to empower households equipped with smart meters to actively reduce electricity consumption during demand peaks in the power system. Targeted to be launched by second half of 2024, this pilot is the first-of-its-kind in Singapore to call upon households to make a significant difference for a more resilient and sustainable energy future. With system peak demand forecasted to increase at a compound annual growth rate of up to 6.5% over the next five years, reducing electricity consumption temporarily during peak demand periods, otherwise known as Demand Response (DR), helps to keep the power system running smoothly and more efficiently by making use of demand-side resources in addition to supply-side (such as large conventional power plants) to balance electricity demand and supply.  For commercial and industrial companies, EMA has seen about a 1.5 times increase in demand-side resources, totaling to about 100MW since the launch of EMA’s regulatory sandbox[1]. With smart meters progressively being deployed to residential and non-residential consumers, more consumers will soon be able to contribute to DR, by using these smart meters to monitor their electricity consumption, making electricity management simpler and more rewarding. Consumers can keep track of their weekly carbon emissions and adjust their electricity consumption habits accordingly to help reduce emissions, thereby minimising their environmental impact. As of September 2023, SP has installed more than 834,000 smart electricity meters across residential and non-residential premises. The residential demand response pilot will use the SP mobile application (SP app) to send alerts to participating households to temporarily reduce or defer their electricity consumption. Households can take action by deferring the use of home appliances such as washing machines or dishwashers, or lower the temperature or even switch off air-conditioning. Participants will in turn enjoy benefits such as financial incentives. On the pilot for households, Mr Ngiam Shih Chun, Chief Executive of EMA, said: “The demand response pilot helps to involve households in lowering electricity demand during peak periods. This can help create a more sustainable and efficient energy ecosystem for everyone.” Mr Stanley Huang, Group Chief Executive Officer of SP Group, said: “Partnering EMA on this pilot, SP Group will empower consumers with digital solutions to be more energy efficient and reduce carbon emission. Enhanced features on our SP App will provide consumers with timely and useful information on their utilities usage and patterns. Insights from this data are aimed at nudging consumers to make adjustments easily to reduce their consumption." [1] In 2022, EMA launched a two-year regulatory sandbox for commercial and industrial companies to optimise their energy consumption. Participating companies will have to manage their electricity demand when activated and receive payments as an incentive for reducing their electrical demand on the national power grid. -- End -- About the Energy Market Authority The Energy Market Authority (EMA) is a statutory board under the Singapore Ministry of Trade and Industry.

Media Release SP GROUP SETS UP FIRST ZERO-EMISSION BUILDING POWERED BY GREEN HYDROGEN IN SOUTHEAST ASIA Singapore, 30 October 2019 – SP Group (SP) has established the first zero-emission building in Southeast Asia that is powered by green hydrogen. Located at SP’s training centre at Woodleigh Park, the self-sustaining building is 100% powered with renewable energy via an innovative Hydrogen Energy System and is disconnected from the national electricity grid. Mr Brandon Chia, Head, Centre of Excellence, SP Group said: “Buildings contribute 40 per cent of energy related carbon emissions worldwide 1 . The Hydrogen Energy System provides a safe and compact way of storing green hydrogen which powers the region’s first zero-emission building. We believe this can be a significant contributor toward Singapore’s climate change pledge to cut national emissions intensity by 36 per cent below 2005 levels by 2030.” The challenge to achieving zero emission The world in its fight against climate change is using various means to lower carbon emissions. One way is to use renewable energy sources. However, in urban places such as Singapore, due to limited land and inconsistent solar energy, achieving zero emission with 100% renewable energy is extremely challenging. Zero-emission solution An alternative is hydrogen as a green energy source. In the Hydrogen Energy System used by SP, electricity from green sources, such as solar, is used to conduct electrolysis. The hydrogen generated from this process is bonded with special metal alloy powders to form metal hydride, compacted and stored in tanks. When electricity supply is required, the stored hydrogen from the metal hydride tanks is slowly released and converted to electricity via fuel cells. As green energy sources are used for electrolysis, this entire process of converting hydrogen to electricity is 100 per cent green, with zero carbon emission. 1 The buildings and building construction sectors combined are responsible for nearly 40% of total direct and indirect CO2 emissions (International Energy Agency). 1 Safe hydrogen storage While there have been other energy systems using hydrogen as a fuel, the key challenge of hydrogen lies in having a storage solution that is safe for deployment in highly-urbanised areas such as Singapore. The system uses special metal alloy as a storage medium to bond with hydrogen. This allows for the storage of a large volume of hydrogen at a much lower pressure over a long period of time without any deterioration. When electricity is needed, the stored hydrogen is released in a slow and regulated manner, making it safer and more compact to be stored in an urban setting. Encourages greater mix of renewable energy The Hydrogen Energy System can mitigate electricity supply fluctuations and intermittency issues – common shortcomings of renewable energy. When there is surplus renewable energy, it can be stored in the form of hydrogen and converted back to electricity when there is a deficit of renewable energy. This ensures that the grid remains stable even with a greater mix of renewable energy introduced, hence encouraging the use of green energy. SP is working with Marubeni Corporation and Tohoku University on the Hydrogen Energy System with special metal alloy storage tanks from Japan, and to customise and integrate it for use in Singapore. -Ends- 2 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.
