STMicroelectronics, a global leader in semiconductor manufacturing, together with SP Group (SP), Singapore’s leading utilities provider and national grid operator, have officially begun operations of Singapore’s largest industrial district cooling system at ST’s Ang Mo Kio TechnoPark. The inauguration was officiated by Low Yen Ling, Senior Minister of State for Trade and Industry and for Culture, Community and Youth.
The new system marks a major step forward in ST’s journey toward carbon neutrality by 2027. It is designed to cut carbon emissions by up to 120,000 tonnes annually and reduce cooling-related electricity consumption by approximately 20 percent. In addition, the system will repurpose over 500,000 cubic meters of water each year by recycling reverse osmosis reject water previously used in cooling towers, significantly improving water efficiency.
“This project demonstrates our commitment to implementing energy-efficient technologies that reduce emissions and conserve natural resources,” said Rajita D’Souza, President of Human Resources and Corporate Social Responsibility at STMicroelectronics. “By integrating district cooling into our manufacturing operations, we are reinforcing our partnership with Singapore in achieving national sustainability goals and creating long-term value for our communities and the environment.”
Stanley Huang, Group Chief Executive Officer of SP Group, emphasized the broader significance of the initiative “Our collaboration with STMicroelectronics represents a landmark achievement in Singapore’s transition toward a low-carbon economy. It exemplifies how partnership and innovation can transform infrastructure to deliver sustainable, energy-efficient solutions that support the nation’s net-zero objectives.”
Developed, owned, and operated by a joint venture between SP Group and Daikin Airconditioning (Singapore), the system has an installed cooling capacity of 36,000 refrigeration tonnes (RT). It supplies continuous chilled water through a centralized closed-loop network, replacing multiple individual chillers across ST’s site. The system serves an area of approximately 90,000 square meters and features chillers in a series counterflow configuration, reducing the energy required for cooling while ensuring reliable, 24/7 operation.
The district cooling plant also incorporates remote monitoring capabilities, enhancing operational efficiency and system reliability. According to Chua Ban Hong, Managing Director of Daikin Airconditioning (Singapore), “This partnership underscores Daikin’s dedication to advancing energy-efficient technologies that contribute to a sustainable built environment and help achieve Singapore’s long-term climate targets.”
The installation frees up about 4,000 square meters of space within Ang Mo Kio TechnoPark, which ST will use to install additional sustainability-focused systems such as perfluorocarbon (PFC) abatement, water reclamation, and volatile organic compound (VOC) control. The project achieved over two million accident-free work hours, a testament to strong safety standards during construction.
Recognized for its sustainability credentials, the cooling plant has been awarded the Building and Construction Authority (BCA) Green Mark Platinum Super Low Energy certification. Through careful material selection and optimized system design, the project achieved a 44 percent reduction in embodied carbon compared with conventional industrial benchmarks.
Beyond the Ang Mo Kio installation, STMicroelectronics and SP Group are expanding their collaboration to enhance sustainability across ST’s Singapore operations. At the Toa Payoh facility, SP is developing a new high-efficiency chiller system under a 20-year chilled-water-as-a-service agreement, scheduled for completion by December 2025. Once operational, the system is expected to cut carbon emissions by approximately 2,140 tonnes each year.
In parallel, ST and SP are deploying a suite of digital monitoring technologies to further improve energy and water management. This includes the Energy Management Information System (EMIS), equipped with 2,400 smart meters and multi-utility sensors, enabling real-time data collection and optimization of energy use. Smart water meters have also been installed across five buildings to help ST track consumption and enhance water efficiency for its critical wafer fabrication processes.
Together, these initiatives reflect a shared vision for a smart, sustainable, and resilient industrial ecosystem. By combining advanced cooling technologies, intelligent data systems, and collaborative infrastructure design, STMicroelectronics and SP Group are setting a new benchmark for industrial decarbonization and digital sustainability in Singapore.
