$320m to power Western Sydney International Airport
Endeavour Energy has ‘switched on’ a suite of energy infrastructure that will power the new Western Sydney International (Nancy-Bird Walton) Airport (WSI) and deliver the first major stage of electricity supply for the Western Sydney Aerotropolis.
The Western Sydney Airport Transmission Substation was officially opened on 3 March 2026 by NSW Deputy Premier and Minister for Western Sydney the Hon Prue Car, and NSW Minister for Climate Change, Energy, the Environment and Heritage the Hon Penny Sharpe, MLC.
The 132 kV digital transmission substation will form part of a broader investment of nearly $320 million in new substations, high-voltage feeders and a switching station. Together, these assets will support airport operations, enable new industries and jobs, and underpin the long-term growth of the Aerotropolis.
“Western Sydney International Airport and the Aerotropolis are once-in-a-generation projects. This investment ensures power is in place not just for today, but will unlock jobs, industries and economic opportunity for decades to come,” Car said.
Sharpe said the investment will ensure that Western Sydney and the Aerotropolis had the critical energy infrastructure needed to grow.
“By supporting early investment in critical electricity infrastructure, we’re ensuring jobs growth across Western Sydney is well planned, resilient and sustainable into the future,” Sharpe said.
The Western Sydney Aerotropolis spans more than 11,000 hectares and will grow around the 1780-hectare Western Sydney International Airport. Together the airport and the Aerotropolis will support more than 120,000 new jobs and attract 1.5 million people to the region over the next decade.
“Western Sydney International Airport is a nation-shaping development and working in partnership with the NSW and federal governments, as well as key stakeholders including the airport, has been critical to ensuring the right energy infrastructure is in place from day one,” said Endeavour Energy CEO Danny Cooper.
WSI CEO Simon Hickey said Western Sydney’s 24-hour airport is built to serve the city for the next century, with reliable energy infrastructure critical to its long-term growth.
“WSI is a modern, technologically enabled airport that will reshape Sydney’s and Australia’s global connectivity and aviation landscape,” he said. “Ensuring we’re powered with world-class, reliable energy is essential for WSI’s 24-hour capability, which will finally put Sydney on the global stage alongside other major gateways around the world.
“Working in partnership with Endeavour Energy to put the right power in place gives airlines, our customers and our business and cargo precinct partners, confidence knowing that the airport will grow in line with demand, while continuing to operate to global standards.”
