Marayong zone substation
Endeavour Energy is replacing the outdoor Marayong zone substation with a new indoor facility, to maintain a safe and reliable electricity supply to Marayong and the surrounding suburbs.
Overview
Marayong Zone Substation is located at the corner of Raymond Street and Charles Street, Blacktown.
This project involves:
- Construction of a new 33/11kV indoor ZS building to accommodate indoor switchgear and facilities
- The replacement of existing transformers, with new low-noise transformers within new enclosures
- Re-configuration of the existing feeder connections, into the new ZS (as required)
- Decommission and demolition of the existing outdoor ZS, including the control building and outdoor switchyard
- Remediation of the existing ZS site and landscaping, after the new ZS is commissioned

The need
Many of the components within the zone substations have reached the end of their service lives and require renewal or replacement. This will ensure a safe and reliable electricity to the suburbs of Marayong, Kings Park, Kings Langley and Lalor Park.
