Powering Sydney's Future

A new transmission cable will be installed from Potts Hill to Alexandria. The Powering Sydney’s Future project will ensure safe, reliable and affordable electricity supply for Sydney’s CBD and surrounding areas.

Why do we need Powering Sydney's Future?

A reliable, affordable and sustainable electricity supply is essential to supporting Sydney’s growth. Parts of the current transmission and electricity supply network were built in the 1960s and 1970s and are approaching the end of their serviceable life. Additionally, increased electricity demand means that residents and businesses in inner Sydney are becoming more vulnerable to blackouts or loss of electricity supply.

Inner Sydney is one of the most critical sections of the electricity network. Through the Powering Sydney’s Future project, TransGrid is working to secure reliable electricity supply through economically viable solutions, with minimal community and environmental impacts. 

What is Powering Sydney’s Future? 

Powering Sydney’s Future involves:
  • Installing a new 20km 330kV underground cable between TransGrid’s substation at Potts Hill and Alexandria 
  • Upgrading substations at Potts Hill, Alexandria and Picnic Point
  • Installing additional pipes so there is space for a second cable to be added in the future as demand increases, avoiding further disruption to local communities
  • Constructing special crossings, such as cable bridges or underbores (underground crossings), for the cable circuit to cross rail corridors, rivers or parks 
  • Temporary use of some public spaces as site offices and ‘laydown areas’ during the construction of the project, for the storage and assembly of equipment 
  • Construction is set to commence in mid-2020 and be completed by late-2022
  • Selecting the preferred project route
    We proposed a preferred cable route in 2017 after examining more than 30 route options. As part of our planning and consultation for the project, we recently identified a new cable route which would lower the construction impacts for local communities. 

    The revised cable route primarily follows local roads and some main roads. 

  • How will Powering Sydney's Future project be built?

    For most of the route we would dig a trench about 3 metres wide by 1.2 metres deep and then install conduits (pipes) before covering them and temporarily restoring the area. To cross waterways and rail lines, we are proposing to build special cable bridges or drill belowground. 

    There will also be associated work at various locations along the route to build underground ‘joint bays’ to pull through and join sections of the new cable. 

  • What work is required?

    The new cable will mainly be installed underground in local roads and some main roads with some cable bridges, or underground drilling, to cross rail lines and waterways. Cable installation will be done in the following stages.
    Stage 1 – Installing conduits (pipes) below ground which will house the cable:

    Stage 2 – Installation of pre-cast underground ‘joint bays’ and communication pits:

    Stage 3 – Pulling cable through the conduits in sections:
    Stage 4 – Joining the cable sections together in underground ‘joint bays’:

    Stage 5 – Permanent restoration of the road in consultation with the relevant Council /road authority:

  • Have your say
    The Powering Sydney’s Future project’s Environmental Impact Statement (EIS) has been placed on public exhibition by the Department of Planning, Industry and Environment (DPIE). The EIS is available on the department’s website at www.planningportal.nsw.gov.au/major-projects/project/9956
    TransGrid is committed to engaging with the community during the planning and construction of Powering Sydney’s Future. We used your feedback in the preparation of the EIS, and it is now on public display.
    The studies that support the EIS are prepared by independent experts and include assessments of potential impacts on the environment, biodiversity, heritage, air quality, amenity, traffic and transport in your community.  
  • How to make a submission:
