Keppel to install solar PV system at Changi Airport

The solar PV system will have a combined generation capacity of 43 MWp.

Keppel will design, build, own and operate a large-scale solar photovoltaic (PV) system on the rooftop areas of Changi Airport’s terminal buildings, terminal auxiliary structures, airfield and cargo buildings.

Keppel aims to complete the PV system in early 2025. Once completed, the solar PV system will have a combined generation capacity of 43 Megawatt peak (MWp).

Of the total capacity, Keppel will install 38 MWp on rooftops, making this Singapore’s largest single-site rooftop solar PV system.

The remaining 5 MWp of solar generation capacity will come from a solar PV system installed at a 40,000 m2 turf area within Changi Airport’s airfield outside of aircraft operational areas. 

“This will be the first time a solar PV system is installed in the airfield – marking the first step towards maximising solar potential at Changi Airport beyond conventional rooftop spaces,” Keppel said.

The rooftop and airfield solar PV systems will generate sufficient solar energy equal to what is needed to power more than 10,000 four-room HDB flats yearly.

With the PV system, CAG can reduce its carbon emissions by approximately 20,000 tonnes yearly, or about 10% of its consumption in 2019.

Keppel will integrate the completed PV system with its Operations Nerve Centre (ONC) sited within the Keppel Infrastructure@Changi building to allow remote monitoring and real-time reporting of solar generation metrics and advanced fault detection and diagnostics for predictive maintenance.
