Eastern Suburbs cable project

 A similar cable project in progress

Ausgrid is planning to retire some of the electrical equipment at our Clovelly substation to maintain a safe and reliable power supply to electricity users in the surrounding areas. The project would involve installing new underground 11,000 Volt cables to connect to Ausgrid's Kingsford and Waverley substations.

Project need

Some of the electrical equipment at our Clovelly substation which is located in Bligh Place, Randwick is ready to be retired as it is nearing the end of its service life. 

Before this can happen, the associated power supply needs to be transferred to our Waverley and Kingsford substations.  We will also need to replace some sections of existing cables to increase the capacity of the network and meet the requirements of the project. 

 

 

Planning cable projects

There are a number of considerations to factor in while planning cable routes. These include:

  • community impacts
  • availability of space around existing utility services
  • environmental and heritage impacts
  • cost (minimising the impact on electricity bills)
  • technical feasibility
  • traffic impacts
  • coordinating works with other infrastructure projects.

Ausgrid has investigated and decided on a proposed cable route for this project, taking into consideration the above factors.  We have divided the route into two sections, based on where construction work would happen - please see the proposed route maps via the links at the top right of this page.

Project dates

The project is currently in the planning stage, with detailed design work and an environmental assessment underway. Ausgrid is working with local residents and businesses and Bayside, Randwick City and Waverley Councils to plan the work to ensure community impacts are minimised.

Construction is proposed to start in late 2017 and be finished in late 2019. Work to install the new cables in streets would be completed in mid 2018. The joining of the sections of cable together and the restoration of roads and footpaths impacted by the work could take a further 12 months. Work to retire the electrical equipment at the Clovelly substation would happen in 2019.

Ausgrid will keep residents, businesses and other stakeholders updated on what to expect during the project stages. 

 

 

Project approval process

Ausgrid is the approving authority for these works under the NSW Environmental Planning & Assessment Act. As part of the approval process, Ausgrid will complete an environmental assessment for this project and liaise with the surrounding community, Council and other relevant authorities.

Community engagement

Ausgrid started engaging with Bayside, Randwick City and Waverley Councils about the project in May 2017 and has also been coordinating with other authorities about their work in the area. This includes Transport for NSW who are working in Kingsford and Randwick to build the new light rail.  

Engagement with residents and businesses along and around the proposed cable route started in late July 2017 with door knocks and face to face meetings. The first project newsletter was distributed from early August 2017. A copy of the newsletter can be found on the right hand side of this page. 
 
Ausgrid is holding two information sessions about the project, see details below:

Community information session 1

Date:     Monday 21 August, 2017
Venue: Level 2 meeting room, The Juniors Kingsford
Address:   558A Anzac Parade, Kingsford
Time:         6pm to 8pm (presentation from 6.15pm)

Community information session 2
Date:     Thursday 24 August, 2017
Venue: Northern Club Room, Margaret Whitlam Recreation Centre
Address:   Waverley Park, Bondi Road, Bondi Junction
Time:         6pm to 8pm (presentation from 6.15pm)

There is no need to book, just drop in.

At the beginning of each session, members of the project team will give a short presentation on why the project is needed and what to expect during construction. A copy of the presentation will be posted on this page after the information sessions. Please contact us if you can't attend the sessions and want more information. 

We will continue to engage with the community and stakeholders during each stage of the project.  Ausgrid welcomes questions or comments about the project at any time (see project contacts top right). Community feedback assists us to identify all potential issues and address them in our construction plans to minimise impacts.

 

 

Construction

This project would involve installing new 11,000 volt cables through streets in Bondi, Waverley, Bronte, Randwick, Kingsford and Daceyville and replacing some sections of existing cables. 

As with any construction work, there would be some noise and dust, and temporary traffic, access and parking disruptions, but we would make every effort to keep these to a minimum. 

Construction would generally include:

  • digging trenches, approximately 1.5 metres wide, to lay conduits (plastic pipes) to hold the new cables
  • filling trenches and resurfacing the area temporarily
  • trenching and resurfacing takes about three days outside each property depending on ground and weather conditions
  • excavating underground joint bays at various locations along the route in the road to feed in and join cables together
  • feeding in and joining the cables, which take several weeks to complete
  • work on the joint bays usually occur in distinct stages
  • replacing some sections of existing cables with new ones
  • typically, restoration work is done in two stages; excavated sections of road are refilled immediately and temporarily resurfaced to allow normal use by traffic
  • replacing some sections of existing cables with new ones
  • final restoration is completed in consultation with Bayside, Randwick City and Waverley Councils and relevant authorities either as sections of work are completed or once the overall project is finished..

Any potential impacts associated with this work are assessed as part of the project's environmental assessment and measures will be put in place to minimise impacts on the community and local environment. 

Ausgrid's work hours are 7am to 6pm Monday to Friday, and 8am to 1pm on Saturdays. Some night work would likely be required on Bondi Road in Bondi and Bronte Road, Birrell Street and Macpherson Street in Bronte, and Anzac Parade in Kingsford, to minimise the impact on traffic, businesses and the general community during the day and as directed by the relevant road authority. 

We would contact affected community members in advance of this work with more information.  

 

 

Clovelly substation

Work to retire the electrical equipment at our Clovelly substation would begin once the new cables are installed and connected to the Waverley and Kingsford substations and the electricity load has been transferred. 
 
Activities to retire the electrical equipment at Clovelly substation would include:

  • disconnecting and making safe the electrical equipment that is no longer required
  • removing the electrical equipment and taking it off site for disposal, reuse or scrap.
