Transformer delivery and installation at Kurnell South zone substation

The replacement of the 1961 Kurnell zone substation has begun, set to increase capacity for Sydney’s rapidly expanding Kurnell peninsula and provide future interconnection with the Cronulla zone substation.

The site’s 37.MVA transformers, 20 11,000V switchgear panels and two auxiliary substations were successfully energised at the end of February and, at the time of printing, crews were working on the 11,000V powerlines running throughout Kurnell, preparing for the transfer to the new substation.

Ausgrid chief operating officer Trevor Armstrong said while the old substation has served the area well for more than 50 years, it was now time for the ageing equipment 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,” he said.

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.
