Singapore’s largest industrial district cooling system begins operations to support STMicroelectronics’ decarbonisation strategy

SP Group has inaugurating its district cooling system at STMicroelectronics (ST) Ang Mo Kio. This is Singapore’s largest industrial district cooling system and ST’s first use of district cooling at a manufacturing facility. Ms Low Yen Ling, Senior Minister of State for Trade and Industry, and Culture, Community and Youth was the Guest of Honour for the event.

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. 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.

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.
