GENEVA, Switzerland and Singapore, Oct 22, 2025 – STMicroelectronics and SP Group (SP) have started operations of Singapore’s first 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 facility will provide chilled water for STMicroelectronics’ operations, reducing energy use and emissions while supporting Singapore’s sustainability goals.
The system is expected to reduce carbon emissions by up to 120,000 tons a year and lower cooling-related electricity usage by about 20%. It will also reuse over half a million cubic meters of water by using reject reverse osmosis each year, previously used in ST’s cooling towers.
This is ST’s first use of district cooling at a manufacturing site and supports its goal of achieving 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, more sustainable 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 Stanley Huang, SP’s group chief executive officer.
Technical Information About the District Cooling System
The system was designed, built, owned, and operated by a joint venture between SP Group and Daikin Airconditioning (Singapore). It has an installed capacity of up to 36,000 refrigeration tons (RT) and supplies chilled water through a closed-loop pipe network that replaces individual chillers. The network cools about 90,000 square meters of office space.
Chillers in series counterflow configuration reduce the energy to cool the water. The system operates 24/7 and includes remote monitoring to support on-site operations.
“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 Chua Ban Hong, managing director at Daikin Airconditioning (Singapore).
The new installation frees about 4,000 square meters at Ang Mo Kio TechnoPark, allowing space for additional installations by ST. Planned upgrades include perfluorocarbon (PFC) abatement equipment, water reclamation systems, and volatile organic compound (VOC) control.
The project recorded more than 2 million accident-free work hours, highlighting the focus on safety during construction. The district cooling plant received the Green Mark Platinum Super Low Energy certification from the Building and Construction Authority for its energy efficiency and sustainable design. Carbon assessments reduce embodied carbon by about 44% compared with industrial building benchmarks. The reduction was achieved through optimized material selection and system design.
Further Collaboration Between STMicroelectronics and SP Group
ST has partnered with SP Group to upgrade the cooling system at its Toa Payoh site. Under a 20-year agreement, SP will design, build, operate, and maintain a new chiller system scheduled for completion by Dec 2025. The system will improve energy efficiency and reduce carbon emissions by about 2,140 tons annually.
STMicroelectronics and SP Group are introducing sustainable technologies across ST’s Ang Mo Kio and Toa Payoh campuses to reduce environmental impact.
SP installed an energy management information system (EMIS) for ST. The system uses 2,400 electricity meters and sensors. It monitors the company’s total energy use. This data helps ST make decisions to improve efficiency and sustainability.
SP also added smart water meters to five of ST’s buildings. These meters track water inflow and gives ST an account of its water consumption. This information helps ST increase water efficiency in its wafer fabrication operations.
