Powering Sydney's Future

A reliable and affordable electricity supply is essential to supporting Sydney’s economy. Parts of the current electricity transmission network were built in the 1960s and 1970s and some underground cables are now approaching the end of their serviceable life. As Sydney’s population grows, the demand for electricity is increasing and replacement of the ageing infrastructure will secure the future supply for residents and businesses in Sydney’s CBD and surrounding suburbs.

Why do we need Powering Sydney’s Future? 

The Powering Sydney’s Future project will secure a reliable electricity supply through economically viable solutions, with minimal community and environmental impacts. 

What is Powering Sydney’s Future? 

  • Installing a new 20km 330kV underground cable between 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 future 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 ‘laydown areas’ during the construction of the project, for the storage and assembly of equipment.
  • Construction is set to commence in early August 2020 and be completed by late-2022.
  • Landowner support services

    We recognise the Powering Sydney's Future project may have increased the level of stress and anxiety experienced by landowners, and have engaged an external service provider – Assure Programs – to provide landowners with short-term support and counselling.

    About Assure Programs

    Assure Programs' psychologists are professionally qualified with a minimum of five years’ post-registration experience. Like doctors, Assure Programs counsellors are bound by a professional Code of Ethics preventing the disclosure of personal information without written consent. 

    The service is confidential and anonymous. TransGrid does not receive any information about who uses these services.

    Sessions generally last one hour and most issues can be resolved within a few sessions. When long-term advice or counselling is required, the counsellor will consider the most appropriate referral option and make a recommendation.

    There is no cost to landowners in accessing this service. 

    How to make an appointment

    If you are a landowner, and would like confidential support and counselling, we encourage you to access the services Assure Programs provides. 

    You can book an appointment by calling Assure on 1800 808 374, or you can request an appointment online: https://assureprograms.com.au/book-an-appointment

    When you call Assure, please let the team know that you are from TransGrid and the business unit is “landowners”. This will ensure you are able to get the support you need. You are not expected to provide the reason – this is a conversation saved for your session with the psychologist. 

  • Latest updates

    Work on the Powering Sydney’s Future project is continuing after the pause on construction from mid-July to early-August 2021 under the NSW Government’s COVID-19 Public Health Order.

    We are now working to complete installation of communications cables (required to monitor and control the electricity cable), and testing the new electricity cable via the previously installed communications pits. 

    Project construction will continue to be done in accordance with NSW Health advice. When returning to local areas after the pause in construction, workers will follow the project’s COVID-19 Safety Plan.

    TransGrid has reached agreement for the City of Canterbury Bankstown to complete permanent road restoration in its local government area, with the cost to be met by TransGrid. Residents and businesses in the vicinity of this work will receive notification from Council (or its contractor) at least 48 hours before road restoration begins.

    We are consulting with the Inner West Council regarding a similar arrangement for the permanent restoration of the roads in that area.

    Construction work at some locations in the community will now continue until late 2021.

  • 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, a new cable route was identified which would reduce the construction impacts for local communities.  

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

  • How will the 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 below ground to install the conduits (pipes).  

    At a later stage, the cable will be pulled through the conduits in sections.  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:

  • Project approval
     The NSW Department of Planning, Industry and Environment (DPIE) has approved the Powering Sydney’s Future project on 14 May 2020. The project which secures the electricity supply for 800,000 people working and living in Sydney’s CBD and surrounding suburbs. 

    This follows the public exhibition and submission of the Environmental Impact Statement (EIS) from 11 October to 22 November 2019. 

    The studies that supported the EIS were prepared by independent experts and included assessments of potential impacts on the environment, biodiversity, heritage, air quality, amenity, traffic and transport in your community.  

    We considered all submissions from the community and stakeholders to the EIS and prepared a Submissions Report in response to questions and issues raised. You can view this report, the EIS, DPIE’s Assessment Report, and DPIE’s Conditions of Approval on the DPIE Major Projects web page and in our Document Library.

  • Community and Stakeholder Reference Group (CSRG)

    TransGrid has established a CSRG for the Powering Sydney’s Future project to enable community participation in project delivery. 

    The group provides a forum for discussions between the project team (including TransGrid and its contractor, Taihan) and local representatives, including community and stakeholder groups and local councils. It is led by an independent chairperson. 

    The CSRG representatives are:

    • Jeff Senior – City of Canterbury Bankstown
