Lidcombe to Sydney Olympic Park cable project

Ausgrid is planning to retire some of the electrical equipment at our substation in Lidcombe to maintain a safe and reliable power supply to electricity users in the surroundings areas. The project would involve installing new underground 11,000 volt cables to connect to Ausgrid’s Olympic Park substation.

Project need

Some of the electrical equipment at our substation in Carter Street in Lidcombe is nearing the end of its service life and needs to be taken out of service to improve reliability and minimise ongoing maintenance costs.

Before this can happen, the associated power supply would need to be transferred to our Olympic Park substation on the corner of Australia Avenue and Bennelong Parkway in Sydney Olympic Park.

Planning cable projects

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

  • cost (minimising the impact on electricity bills
  • minimising community and traffic impacts
  • avoiding existing utility services in roads
  • ground conditions
  • environmental and heritage impacts
  • public health and safety
  • technical feasibility.

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 is doing an environmental assessment for this project and liaising with the surrounding community, councils and other relevant authorities.

Project dates

Ausgrid started planning the project in 2017. This process involved consulting with the Sydney Olympic Park Authority and the City of Parramatta Council to obtain early feedback on the preferred cable route.

Ausgrid is also seeking community feedback for this project so we can use local knowledge as part of the planning process.

We are in the process of conducting an environmental assessment for this project. Tenders will be called for the trenching work in mid-2018. Construction would start soon after.
Work to install the new conduits (plastic pipes that house the electricity cables) would start in mid-2018 and take about three months to finish. The cable installation work would follow the conduit installation. Work to join sections of cable together would be done in early 2019.


Community engagement

Ausgrid began engaging with the Sydney Olympic Park Authority about the project in late 2017 and a meeting was held with the City of Parramatta Council earlier this year.

Engagement with residents and businesses located along and around the preferred cable route started in late March 2018 with the distribution of the first newsletter about the project. A copy of the newsletter can be found on the right hand side of this page.

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 cables in streets in Lidcombe and Sydney Olympic Park via trenching in roads and footpaths. In some locations, the cables would be installed into existing conduits.
As with any construction work, there would be some noise and dust, and temporary traffic impacts but we would make every effort to keep these to a minimum.

 

Construction would involve:

  • digging trenches, approximately 1 metre wide, to lay conduits (plastic pipes) to hold the new cables
  • filling trenches and resurfacing the area temporarily
  • excavating underground joint pits and communication pits at various locations along the route to feed in and join sections of cables together
  • permanently restoring of all impacted areas. 

 

Generally, restoration work is done in two stages:

  • Excavated sections of road are refilled immediately and temporarily resurfaced to allow normal use by traffic.
  • Final restoration would be completed in consultation with the Sydney Olympic Park Authority and the City of Parramatta Council 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. Measures would be put in place to minimise impacts on the community and local environment.

Work hours would align with Ausgrid’s standard hours of 7am to 6pm Monday to Friday, and 8am to 1pm on Saturdays, with no works on Sundays or public holidays.

Some night work could be required to minimise the impact on traffic, businesses and the general community during the day.  We would contact affected community members in advance of this work with more information.
