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 Expands Marina Bay District Cooling Network With New Partnerships 8 Shenton Way, IOI Central Boulevard Towers, 80 Anson Road, Marina Bay Sands Integrated Resort Expansion and NS Square, will be connected to the world’s largest underground district cooling network Sustainable cooling solution helps Marina Bay avoid almost 20,000 tonnes of carbon emissions annually Singapore, 20 April 2022 – SP Group (SP) announced that it will be providing its energy efficient district cooling services to five upcoming new and retrofit developments – 8 Shenton Way (formerly AXA Tower), the commercial component of 80 Anson Road (formerly Fuji Xerox Towers), IOI Central Boulevard Towers, Marina Bay Sands Integrated Resort Expansion and NS Square – through its Marina Bay District Cooling Network. Marina Bay is planned as a sustainable live-work-play district, and all developments are served by a comprehensive underground network of common services tunnels that houses the district cooling system.1 The addition of the five developments will further expand the world’s largest underground district cooling network, bringing the total number of buildings served by SP’s Marina Bay operations to 28. SP’s sustainable cooling solution will help the Marina Bay district reduce its carbon emissions by 19,439 tonnes annually while providing the same cool comfort. This is equivalent to removing 17,672 cars off our roads. At an appreciation event held earlier today which marked the expansion of the Marina Bay District Cooling network, Mr Desmond Lee, Minister for National Development and Minister-in-charge of Social Services Integration, presented certificates of appreciation to the building owners of the five buildings – City Developments Limited (CDL), IOI Properties, Marina Bay Sands Singapore, NS Square, and Perennial Holdings – affirming their commitment to the sustainable development of our city centre. Through subscribing to district cooling, the new developments will enjoy reliable cooling comfort with the network achieving zero supply interruptions since the Marina Bay District Cooling operations started in 2006. Without the need to invest in their own chillers, the new developments will enjoy a lower initial investment cost compared to a conventional air-conditioning system. The savings on equipment, operating and maintenance costs will also reduce the total cost of ownership by up to 15 per cent. Having centralised chiller plants also frees up prime space for other commercial or lifestyle purposes, potentially increasing asset yield for building owners. SP’s Group Chief Executive Officer, Mr Stanley Huang, said, “SP Group is the largest district cooling solutions provider in Singapore. With the expanded infrastructure in place, we are pleased to extend the same reliable and sustainable solution to other buildings in Singapore’s core financial district and look forward to welcoming more partners to this network. Together, we can accelerate the development of greener buildings and cities to achieve Singapore’s ambitious sustainability targets.” In addition to the energy savings and the reduction in carbon emissions, developments will also benefit from the centralisation of ownership and maintenance of their cooling systems under a district cooling operator, ensuring optimal operations at all times. SP as the district cooling operator is responsible for meeting the industry sustainability standards. Under the latest BCA Green Mark 2021 (GM: 2021) green building certification scheme, buildings supplied by an external district cooling system (DCS) plant have a dedicated pathway to demonstrate their energy efficiency performance, allowing for a more seamless certification experience. With the inclusion of these new customers, SP will be increasing the capacity of its Marina Bay district cooling network to 70,000 refrigerant tons (RT). It will also add more than two kilometres of underground insulated pipes to the network to cater to the additional demand and cooling capacity. To further enhance the reliability of the network, SP is exploring installing thermal storage tanks in the neighbouring Central Business District to increase the network’s energy storage capacity. These auxiliary chilled water tanks will enable the existing network to significantly reduce its peak load consumption and support future expansion of the cooling network beyond the Marina Bay vicinity. Additional energy storage capacity will also facilitate the incorporation of more renewable energy sources to the grid by mitigating the intermittency of renewables while maintaining grid stability and reliability. The deployment of energy storage systems, such as thermal storage tanks, is in line with government’s energy storage target and vision of a clean and efficient energy future. SP continues to actively engage with potential customers to further expand the Marina Bay district cooling network. It is currently studying the feasibility of M Hotel Singapore, a hotel under the CDL Group, being the first brownfield hotel development to incorporate district cooling in its operations. In addition to the Marina Bay district cooling network, SP is also collaborating with the Housing and Development Board (HDB) to deploy Singapore’s first residential centralised cooling system for up to 22,000 households at the upcoming Tengah housing estate by 2023. SP will also be developing Singapore’s first brownfield, sustainable cooling solution for a town centre at Tampines. When completed, SP will be operating a total 118,500 RTs of cooling capacity through its district cooling networks, extending its lead as the biggest provider of district cooling solutions in Singapore. 1District cooling in Marina Bay provides centralised cooling to developments in the area. There are two district cooling plants in Marina Bay, both situated underground and seamlessly integrated with the surrounding developments, providing greater reliability of services and allows more efficient use of energy across the district. SP Group operates the district cooling network in Marina Bay. - Ends - Quotes from new partners Quote from City Developments Limited for 80 Anson Road (formerly Fuji Xerox Towers) We are delighted for 80 Anson Road’s commercial space to be part of SP Group’s initiative to provide sustainable cooling solutions to the Marina Bay district.

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.
