West Pittwater reliability project

Project Overview

Ausgrid plans to improve the reliability of the local power supply to West Pittwater (Elvina Bay, Lovett Bay and Southern Morning Bay). This has followed extended power outages in December 2013 and February 2015.

West Pittwater isuniquely positioned in regards to access and connectivity to the mainland. An 11,000 Volt submarine cable currently supplies the area, however, Ausgrid is considering a broad range of options aimed at improving energy security.

This web page provides a central platform for community feedback and project updates. It will be updated regularly and moderated throughout all stages of the project. You can provide feedback using the interactive map, find project information and documents, contact the project team and find out about upcoming events.

Ausgrid plans to improve the reliability of the local power supply to Scotland Island and West Pittwater (Elvina Bay, Lovett Bay and Southern Morning Bay). This has followed extended power outages in December 2013 and February 2015.

Both Scotland Island and West Pittwater are uniquely positioned in regards to access and connectivity to the mainland.  An 11,000 Volt submarine cable currently supplies both areas, however, Ausgrid is considering a broad range of options aimed at improving energy security.

Work so far

Ausgrid has already undertaken a range of measures to improve the reliability of the power supply, whilst it investigates longer term options. Works completed to date include the replacement of a number of sections of the existing submarine cable to reduce the chance of future impact from erosion and third party damage. 

In addition to these works, Ausgrid has completed a review of response times to outages in the area which will allow workers to respond faster and more efficiently in the event of future outages. Improvements include, but are not limited to, better sourcing arrangements for barges and generators, increased storage of equipment on site, and better access to information on weather, road and maritime conditions.

It should be noted that since 2015, there has not been a power outage involving either of the two submarine cables.

Ausgrid’s original preferred option was to install an 11,000 Volt cable between Catherine Park and Little Lovett Bay. Whilst this is still a feasible option, we are undertaking further analysis to ensure all relevant technology, environmental and safety standards, value for our electricity customers and community feedback is considered to be able to provide a solution that best meets all necessary requirements.  It is important to note that the proposed additional cable between Catherine Park and Little Lovett Bay would not have prevented the outages experienced due to the Friday 17 February storms, nor allowed for a quicker response because of the significant damage to the low voltage network.

Update on our plans

Ausgrid plans to present a number of options for feedback at community sessions in mid-2017. To assist us assess current options for feasibility we would like your feedback on a range of topics. This webpage will be updated regularly with details of community sessions as well as how you can provide feedback.
