Endeavour Energy today unveiled a suite of critical 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.

NSW Deputy Premier, the Hon. Prue Car, Minister for Western Sydney joined NSW Minister for Climate Change, Energy, the Environment and Heritage, the Hon. Penny Sharpe, MLC, to officially open the Western Sydney Airport Transmission Substation – a critical supply of secure, reliable electricity to power NSW’s first new international airport in more than a century.

The transmission substation is part of a staged rollout of energy infrastructure, forming 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.

Deputy Premier and Minister for Western Sydney said the project demonstrated how government is supporting industry to invest and grow jobs and opportunities in Western Sydney.

“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.” said the Deputy Premier.

Energy Minister Penny 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,” Minister 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.

Endeavour Energy CEO, Danny Cooper, said delivering energy infrastructure at this scale required innovation, careful planning and strong partnerships.

“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,” he said.

“At Endeavour Energy, we listen to stakeholder feedback, and we plan well ahead for growth, designing the energy systems that future industries and communities in this region depend on.”

WSI CEO, Simon Hickey said Sydney’s new 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.”

The Western Sydney Airport Transmission Substation forms part of Endeavour Energy’s broader, long-term investment program across Greater Western and South West Sydney, with further stages of energy infrastructure already planned as the region continues to grow.

This investment builds on an earlier announcement by Endeavour Energy and Transgrid confirming plans for a new Kemps Creek Bulk Supply Point, which will further increase capacity and resilience across the Aerotropolis as electricity demand grows.

Energy infrastructure in the Aerotropolis

  • Western Sydney Airport Transmission Substation is a new 132 kV digital transmission substation built to deliver the first major power supply into the 1780-hectare Western Sydney International (Nancy-Bird Walton) Airport. As Endeavour Energy’s largest indoor transmission substation, it can scale as the airport expands over the coming decades, supporting one of Australia’s largest infrastructure projects and a region expected to attract 1.5 million people within 10 years. (Commissioned).
  • Western Sydney Airport Zone Substation supplying power to Burra Park, a new logistics and industrial hub opposite the airport terminal; the Agribusiness North precinct which will host high-tech food production, logistics and data-driven industries and Science Park. This new substation is housed alongside the Western Sydney Airport Transmission Substation. (Expected commissioning June 2026).
  • The Aerotropolis 132 kV Feeder Network is an approximately 30 km of underground high voltage backbone feeder delivering sub-transmission electrical supply through Bringelly, Luddenham, Orchard Hills, Kemps Creek, Badgerys Creek and South Erskine Park forming the core supply route into the Western Sydney Aerotropolis region. As part of Endeavour Energy’s major infrastructure program, 30 km of new 132 kV feeders have been constructed to bring power into the Aerotropolis and its emerging residential, commercial and industrial centres. This feeder network supplies critical precincts including Sydney Metro – Western Sydney Airport Line, Sydney Science Park, the Western Sydney International Airport, Agribusiness and Bradfield City precincts, all of which depend on new high-capacity, resilient energy infrastructure to operate at scale. (Commissioned).
  • North Bradfield Zone Substation will provide early and reliable power to Bradfield City – Australia’s first new city in more than 100 years, eventually delivering 10,000 homes and 20,000 jobs. It will also supply the logistics and industrial hub at Inghams Business Park. (Expected commissioning late March 2026).
  • Badgerys Creek Zone Substation: Will support growing electricity demand across Badgerys Creek industrial and commercial precinct. The new 132/22 kV digital substation will supply two major business parks, new commercial developments and Sydney Water’s Upper South Creek Advanced Water Recycling Centre. Stage 1 includes the Zone substation and a 132 kV underground transmission feeder from the Western Sydney Airport Transmission substation. To further strengthen reliability and secure long-term supply, stage 2 includes a second 132 kV underground feeder, connecting into the existing Transgrid Sydney West Bulk Supply Point (BSP) and Endeavour Energy’s North Leppington Zone substation. (Stage 1 to be commissioned mid-2027, Stage 2 to be commissioned mid-2028).
  • Orchard Hills Switching Station is a key switching hub, connecting the 132 kV underground transmission feeder with substations to deliver power to the Aerotropolis. It is particularly crucial for the Sydney Metro – Western Sydney Airport Line, ensuring a stable power supply for the new metro connection from St Marys to the airport and Bradfield City.
