Artarmon to Mosman cable project

 

Ausgrid is planning a new cable route between our Willoughby substation on Campbell Street, Artarmon and our Mosman substation on Harbour Street, Mosman. 

Project need

Ausgrid’s Mosman zone substation is currently supplied by one 132, 000 Volt cable from the Willoughby substation, and a further two 132, 000 Volt cables from the Castle Cove zone substation in Chatswood.

These cables are more than 45 years old and are now approaching the end of their service life. They have been subject to failures in recent years and need to be replaced to maintain a safe and reliable power supply to customers.

In addition, Ausgrid is in the process of retiring all cables of this type from its network.

Project status

Project approval process

Ausgrid is responsible for assessing and approving works under the Artarmon to Mosman cable project. This process includes preparation of an environmental assessment (Review of Environmental Factors or REF). The REF includes a range of specialist studies and input from the community, councils and other authorities.

The REF will be placed on exhibition at several locations and the community invited to make submissions. People along the proposed route 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.
