Rozelle substation upgrade

Ausgrid is planning to upgrade its existing substation located on Manning Street, Rozelle.

The upgrade will include construction of a new building to house new electrical equipment and replacing one of the two transformers onsite. Two transformer bays will also be built to contain the existing and replacement transformer.

Project need

Substations such as the one on Manning Street are known as subtransmission substations and are part of the power supply chain that delivers power from where it is generated to electricity users.

Subtransmission substations distribute power to our zone substations at 132,000 and 33,000 Volts. Smaller substations, such as the ones you may have seen in large green boxes by the side of street then convert the power to voltages suitable for use in homes and businesses. 

All substations house transformers to convert electricity to lower voltages and switching gear that allows us to safely operate and maintain the electricity network.

Planning the new substation

Ausgrid is currently in the early planning stages for this project. As part of this process, we have consulted with Inner West Council and other key stakeholders in the area. We have also engaged architectural specialists Brewster Murray to lead the design of the new building.

As part of the process to develop these plans, Ausgrid and our architects have considered a range of factors, including:

  • electrical and equipment requirements
  • environmental and heritage impacts
  • community impacts
  • constructability
  • cost (minimising the impact on electricity bills).

Community involvement

Community feedback will be considered by Ausgrid in finalising the building design. Visit our Engagement Hub to review the two proposed building designs, select a preference and provide feedback. 

Community newsletters were issued to properties close to the substation site in March 2018.

All community feedback is considered by the project team as part of the process to minimise impacts during construction. To find out more or provide feedback to Ausgrid, please get in touch via the contacts on the right of this page. 

Project approval process and environmental assessment

Under the NSW Environmental Planning and Assessment Act 1979, Ausgrid is the consent authority for this project.

As part of this process, an environmental assessment known as a Review of Environmental Factors (REF) will be prepared. This process involves preparing specialist studies and collecting input from the community, councils and other authorities.

The REF will be placed on exhibition at several locations and the community will be invited to make submissions. Properties close to the substation will receive a newsletter with further details on this process.

Following the REF exhibition, Ausgrid will review all submissions and prepare a report. Ausgrid will then determine the project for approval based on information contained in the REF, the specialist reports and other relevant documents.
