North Bradfield zone substation
Endeavour Energy is establishing a new zone substation, to maintain a safe and reliable electricity supply for the growing western suburbs of Sydney.
Overview
Endeavour Energy is proposing to construct and operate a new zone substation at 475 Badgerys Creek Road in Badgerys Creek, within the Liverpool City Council (LGA), to be known as the North Bradfield zone substation (ZS). The substation site is approximately 17km southeast of Penrith and 25km southwest of Parramatta.
The project involves:
- Construction of a new 132/22kV digital zone substation with two 45MVA transformers comprising of a 132kV outdoor switchyard
- Installation of prefabricated buildings to accommodate indoor 22kV switchgear, protection and control equipment, communications and batteries, and facilities
- Installation of required ducts to connect cables to a future Battery Energy Storage System (BESS)
- Addition of security fencing, gates and lighting
- Landscaping

The need
The proposed zone substation will strengthen reliability, while servicing 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, providing the capacity to connect new customers in the Western Sydney Aerotropolis Core Precinct. Then, in the future, there will also be an opportunity to install grid batteries within the substation.
