Maximum length of a major CBD power outage following completion
The Waratah Place project and Melbourne CBD Security of Supply project ensures that if unexpected events occur on major supply lines, such as extreme weather, fires, traffic accidents or infrastructure failures, then the network has a ‘double backup’ to provide continuous supply to homes and businesses in the CBD.
At the heart of the Security of Supply project is the rebuilt Waratah Place Zone Substation. The zone substation will allow power to be diverted around the grid so the duration of a major power outage is limited to no more than 30 minutes.
Prior to the Waratah Place Zone Substation, the CBD’s power supply could only withstand one major fault on the 66kv network. This project was designed to ensure the city can withstand two major outages, with minimal impact to customers.
While ensuring reliability, the Waratah Place Zone Substation has also been designed to help reinvigorate the heritage of the vibrant laneway culture around Chinatown.
