Western Sydney International Airport’s (WSI) Chief Executive Officer, Guy Chalkley has announced the construction of a digital transmission substation, which will supply a reliable, secure, and sustainable energy solution for the new airport and surroundings.
“As the electricity distribution network that has been powering Western Sydney for over 130 years, we are proud to power one of the largest infrastructure projects in Australia,” Chalkley commented.
“Our energy solution is designed to meet Western Sydney International Airport’s requirements while also supporting the connectivity to the region which is expected to attract 1.5 million people over the next decade.”

The new digital transmission substation and electrical infrastructure will provide electricity to the 1780-hectare airport site and surrounding business hubs. The high voltage indoor transmission substation will initially provide 120MVA of capacity but has the capability to grow and expand with the airport.
Chalkley added that the new partnership would create jobs through delivery of new energy infrastructure and support the economic development of Western Sydney, Australia’s third largest economy.
