Ausgrid releases plans for new Sydney substation

Ausgrid has revealed the preferred design and layout of a new $30 million substation to be constructed in Greenacre in Sydney.

Chief operating officer Trevor Armstrong said it would replace the existing zone substation in Rosedale Avenue, which was commissioned back in 1970.

“The current substation has been in service for more than 45 years, nearing the end of its working life and needs to be replaced,” Mr Armstrong said.

“This development will help secure the power supply for 16,000 local homes and businesses into the future.”

The new Greenacre substation will be built on Ausgrid-owned land next to the existing substation with construction expected to begin in November.

The substation will be initially equipped with two 132/11kV 50MVA transformers.

The layout of the substation also allows for construction of a third transformer bay, if the electrical demand in the area increases in the future.

Following the construction of the new substation the 11kV load will be transferred to the new substation and the existing substation will be decommissioned.

A Review of Environmental Factors or the project has been prepared and Ausgrid is seeking further feedback from the community.
