STMicroelectronics' district cooling system supports decarbonization strategy

STMicroelectronics and SP Group have launched Singapore’s largest industrial district cooling system at the Ang Mo Kio TechnoPark. The system commenced operations on October 21, 2025, inaugurated by Senior Minister of State Ms. Low Yen Ling. This initiative aims to enhance the environmental performance of ST's semiconductor manufacturing operations.

The new cooling system is projected to lower carbon emissions by up to 120,000 tonnes annually and reduce cooling-related electricity costs by 20 percent. It will also repurpose more than half a million cubic meters of water each year through the use of reject reverse osmosis water from existing cooling towers.

This marks STMicroelectronics’ first implementation of district cooling at its facilities, reinforcing its commitment to achieving carbon neutrality by 2027. Rajita D’Souza, President of Human Resources and Corporate Social Responsibility (CSR) at STMicroelectronics, emphasized the project’s alignment with Singapore's sustainability objectives.

Designed and operated by a joint venture of SP Group and Daikin Airconditioning (Singapore), the system includes a centralized pipe network that distributes chilled water to a service area of approximately 90,000 square meters. This design replaces the traditional individual chillers found in each building, thereby streamlining operations.

The district cooling system has achieved over 2 million accident-free man hours during its construction phase. It has also received the Green Mark Platinum Super Low Energy certification for its favorable energy efficiency metrics. The design considered whole-life carbon assessments, achieving a 44 percent reduction in embodied carbon compared to industrial benchmarks.

Further collaboration between STMicroelectronics and SP Group targets additional upgrades, including a new high-efficiency chiller system installation at the Test Outcome Analyzer (TOA) Payoh site aimed at reducing carbon emissions by approximately 2,140 tonnes annually. Both companies are also deploying smart energy management tools to enhance resource efficiency across their campuses.
