Ausgrid is installing a new 132,000 volt underground cable and spare conduits for a future second cable between Kingsford and Randwick to replace existing cables that are nearing the end of their service life.
Our substation in Randwick is serviced by 132,000 volt underground cables from substations in Waterloo and Double Bay. The cables from Waterloo are nearing the end of their service life and need to be replaced to maintain a reliable electricity supply to customers.
Ausgrid is planning to retire the Waterloo substation in the next few years so the new cables can’t be installed along the same route as the existing ones. The most cost effective solution would be to install the new cables and spare ducts from the closest supply point to Randwick that has available 132kV connection points. That is our Kingsford substation.
We are planning to retire the existing cables from Double Bay in the mid-2020’s.
The project is part of a program to retire fluid filled cables across our network.
The project was approved for construction in late October 2018 and construction began in early 2019. Taihan and Garde are doing the work on behalf of Ausgrid.
Work to install the conduits that will house the new cables is well underway in roads between our substations in Kingsford and Randwick. Most of the work is being done using conventional trenching, but part of the route involves a bore under Alison Road, between the upper and lower sections of St Marks Road in Randwick.
Once the conduits are installed, work will begin to feed the new electricity cables into them. Construction is expected to be complete in the last quarter of 2019. Work to retire the existing 132,000 volt cables between our substations in Waterloo and Randwick will begin in late 2019 and extend into 2020.
Ausgrid will keep residents, businesses and other stakeholders updated as the project progresses.
Under the Environmental Planning and Assessment Act 1979, Ausgrid is the nominated determining authority for assessing and approving works for the Kingsford to Randwick cable project.
As part of this process, an environmental assessment (known as a Review of Environmental Factors or REF) has been prepared. The REF assesses the potential environmental impacts associated with the construction and operation of the new cables and will include a range of specialist studies and feedback from the community, councils and other authorities.
The REF was on public exhibition for comment from Friday 7 September to Thursday 27 September 2018. Ausgrid considered all feedback received as part of the process of assessing the project for construction. The final REF can be viewed in the 'Review of Environmental Factors' section below.
We will continue to engage with the community and stakeholders during construction. Ausgrid welcomes questions or comments about the project at any time (see project contacts top right). Community feedback assists us to identify potential issues and address them in our construction plans to minimise impacts
This project will involve installing the a new 132,000 volt cable and spare conduits through streets in Randwick and Kingsford. Retiring the existing cables between our substations in Waterloo and Randwick will involve some work at various locations along that cable route and at the substations themselves.
As with any construction work, there will be some noise and dust, and temporary traffic, access and parking disruptions, but we will make every effort to keep these to a minimum.
