PROPOSAL TO CONSTRUCT AND OPERATE
TWO UNDERGROUND POWER CABLES FOR
PROPOSED NEW WETHERILL PARK DATA CENTRES
This proposal aims to deliver a safe, secure and reliable electricity supply to support the development of critical data centre infrastructure in New South Wales, ensuring long-term resilience and efficiency for the growing digital economy.
It involves the construction of two new underground power cables through the Wetherill Park Industrial Commercial area, ensuring a reliable electricity supply for new data centres while maintaining the safety, reliability, and quality of power supply to surrounding businesses.
The proposal involves:
- trenching along various roads and through Wetherill Park Zone Substation to the data centres site in Davis Road to install new cable ducts
- trenching short 50-100 metre sections immediately followed by backfilling and temporary restoration to
minimise traffic disruption and inconvenience
- under boring the Parramatta to Liverpool Transitway that crosses Davis Road near the Widemere Road
intersection to install new cable ducts
- establishing two temporary cable joint bays for each underground cable in Davis and Widemere Roads,
which will be opened for short periods during cable installation, jointing and testing
- the installation of the new underground power cables to supply electricity from the zone substation to the new data centres site
- permanent road restoration carried out after testing and commissioning of the cables.
As the electricity Network Operator and determining authority for electricity network development, Endeavour Energy is assessing a Review of Environmental Factors (REF) for the proposal under Part 5 of the Environmental Planning and Assessment Act 1979, which includes inviting stakeholder comments
The REF details the project benefits, and potential environmental impacts and proposed mitigating measures to balance community needs with the environmental, technical and financial aspects of the development.
The draft REF is available for review and comment at: https://www.endeavourenergy.com.au/in- thecommunity/works-in-yourarea/underground-power-supply-to-wetherill-park-data-centres
For further information or to make a submission, please contact Jason Chan at environment@endeavourenergy.com.au up to 3 July 2025. All submissions will be considered as part of the assessment of the development.
If the development is approved, adjacent businesses along the route and other relevant stakeholders will again be notified prior to any planned works. This will provide another opportunity for feedback to minimise disruption and inconvenience during construction.
