Proposal to construct north bradfield zone substation


Endeavour Energy is proposing to construct and operate a new zone substation at part 475 Badgerys Creek Road, Badgerys Creek, NSW to be known as North Bradfield Zone Substation (ZS).

The project involves:

  • construction of a new 132/22kV digital zone substation with two 45MVA transformers comprising of a 132kV outdoor switchyard
  • installing prefabricated buildings to accommodate indoor 22kV switchgear, protection and control equipment, communications and batteries, and facilities
  • installing required ducts to connect cables to a future Battery Energy Storage System (BESS)
  • security fencing, gates and lighting
  • landscaping.

The need

The proposed zone substation will strengthen reliability and service the large-scale infrastructure development in the Bradfield region in line with NSW Department of Planning and Environment's plans. The new substation would be connected to the Aerotropolis backbone feeder to provide sufficient capacity to connect new customers in the Western Sydney Aerotropolis Core Precinct. There will also be an opportunity to install grid batteries within the substation in the future.


The proposed North Bradfield ZS is located at part lot of 475 Badgerys Creek Road in Badgerys Creek within the Liverpool City Council (LGA). The substation site is approximately 17km southeast of Penrith and 25km southwest of Parramatta.
