Powering WA’s clean energy future

To meet evolving energy needs, the State Government is transforming the electricity network to deliver cleaner, more sustainable power to West Australians now and in the future.

Clean Energy Link – North is a critical first step in achieving this extraordinary transition. By strengthening the existing northern network we can connect more renewable energy sources, helping WA to meet its net-zero targets.

What is the Northern Terminal to Henley Brook Substation project?

Western Power is building a new 5km overhead 132kV transmission line to branch off from existing network infrastructure, boosting capacity flow between Perth and the Mid West region, benefiting both industry and the wider community.

Starting at the connection point of the existing 132kV line on Woollcott Avenue in Brabham, the new line will travel along the eastern side of Drumpellier Drive before ending at Henley Brook Substation on Barrambie Way.

This line is an important step forward in enabling industry and WA to reach decarbonisation goals.

The line design aligns with existing network infrastructure in the area and will consist of wood poles.

Project line route and terminal site locations

The below map shows a representation of the proposed T-Off to Henley Brook 132kV line route. You can click the markers to identify key sites and points on the map.

We worked closely with key community representatives in 2024 to select an optimal line route and design to minimise local impacts.

The line route, and its design and build, has been selected to enhance ongoing local and state government projects for this area. It has been chosen to ensure use of existing infrastructure, easements and affordability.

In consultation with local and state Government agencies and authorities, including City of Swan, Whiteman Park, Perth Transport Authority (PTA), Water Corporation, Department of Planning, Lands and Heritage (DPLH), Department of Biodiversity, Conservation and Attractions (DBCA), we carefully evaluated various route options, considering a range of factors and constraints including;

  • land use and landownership
  • areas of Aboriginal and cultural significance
  • environmental values
  • benefits and potential impacts to industry, employment and income for communities
  • resident and community health and safety values
  • public amenities
  • bushfire management
  • design efficiency and constructability
  • use of existing corridor and/or infrastructure
  • solution reliability, maintainability and sustainability
  • project delivery timeframe
  • economic viability.

Visual amenity and broader community values were paramount considerations in the route and design selection process.

The process included rigorous environmental and cultural heritage assessments and securing all necessary approvals.
