It is among 38 developments in the Central Business District that will be served by the Marina Bay district cooling network.

There are 24 developments currently connected to the network, including two hotels - Marina Bay Sands and The Westin Singapore (within Asia Square Tower 2) - as well as IOI Central Boulevard Towers, The Sail @ Marina Bay and One Marina Boulevard, SP told The Straits Times.

Under the agreement, SP will take charge of operating Suntec City's cooling system, which will be interconnected with the Marina Bay district cooling network via neighbouring developments by 2027.

Suntec City's cooling system is made up of a single central chiller plant with an installed capacity of about 20,000 refrigerant tonnes (RT), providing cooling services across its five office towers, retail mall and convention centre, covering a total net lettable area of more than 3.4 million sq ft.
