Botany Bay Cable Project

Ausgrid has replaced 132,000 volt transmission cables between Earlwood and Matraville (Canterbury and Bunnerong subtransmission substations) with two new 132,000 Volt cables from Kurnell, including a submarine cable crossing of Botany Bay. The project also includes associated substation works at the Kurnell and Bunnerong substations.  

The cables have now been laid with some remaining work at the substations to be completed.

The Botany Bay cable project is a key part of Ausgrid’s plans to maintain a safe and reliable electricity supply to homes and businesses in the southern, eastern and inner suburbs of Sydney. View an indicative route map of the replacement 132,000 volt cables.
