Ausgrid's Kurnell South Zone Substation Energized

Ausgrid's 1961 Kurnell zone substation is set to be replaced with the final stage of work beginning. Last week, equipment at the new substation was successfully energized and crews will now be working on the 11,000 V powerlines running throughout Kurnell preparing for their transfer to the new substation, Ausgrid Chief Operating Officer Trevor Armstrong said.

“This new substation will help provide a safe and reliable supply to important industrial customers in Kurnell,” Armstrong said. “While the old substation has served the area well for more than 50 years, it is now time for it to be replaced. Helping provide a safe and reliable power supply to not only homes and businesses, but major industries as well, is a key part of Ausgrid’s operations.”

The new substation is on Captain Cook Drive. Ausgrid will be working with industrial customers who require alterations to their internal networks, before the supply can be safely switched over to the new substation.

Equipment installed in the new substation includes:

  • Two X 37.5 MVA transformers.
  • 20 X 11,000 volt switchgear panels.
  • Two X auxiliary kiosk substations.

The new zone substation will supply the Kurnell peninsula and provide future interconnection with Cronulla Zone substation to increase capacity for and improve reliability in Cronulla and Woolooware.

Ausgrid's electricity network supplies power to 1.6 million homes and businesses across Sydney, the Central Coast and the Hunter.
