Public consultation is an important part of transparent decision-making. We welcome feedback on the following projects to help determine their direction and ensure we are meeting customer and industry needs. 

Powering East Perth

Connecting our customers and communities

Western Power is working to deliver a bright future for East Perth by investing in the electricity network that supplies the community.

Perth is growing rapidly, with new residential developments, commercial spaces and entertainment precincts. Safe, reliable power is vital to support this growth. To meet the changing needs of our customers, we are continually upgrading our electricity infrastructure.

As part of this ongoing improvement, we are our ageing Forrest Avenue Substation (see coloured square on the map below). This means that in early 2022, customers currently supplied with electricity via the Forrest Avenue Substation will instead receive their supply via the recently upgraded Joel Terrace Substation, located near the old East Perth station.

About the project

The project involves installing six underground cables between the Forrest Avenue Substation and Joel Terrace Substation.

  • Underground ducts are already installed to contain two of these cables, as indicated by the orange line in the map.
  • The remaining four cables will be installed in new ducts along a separate cable route through a narrow open trench, as indicated by the green line in the map.

The work to excavate the trench and to install the cable will be completed in short sections to minimise impact on residents, businesses and road users. After the work is complete, we will reinstate the area to equal or better than original condition. This will also comply with local government and Main Roads requirements. 

We are in consultation with the City of Perth, City of Vincent, Public Transport Authority and Main Roads WA to determine the best way to carry out the work with the least disruption and to obtain all the necessary approvals.

How this work may affect you

Businesses and residents along the cable route will be notified before construction starts nearby, and provided information specifi c to that location.

We will work hard to keep disruptions to a minimum, however you may notice the following during works in your area:

  • some noise for short periods
  • parking bay closures and parking restrictions
  • some traffic lane closures, with lower speed limits in place to ensure safety
  • some night and weekend work to minimise disruption to traffic and some businesses.

The work to excavate the trench and install the cable will be completed in short sections to minimise impact on residents, businesses and road users.

East Perth

Picton South transmission network reinforcement

To secure future power supplies in the South West region, Western Power is taking on a significant project in the region – the Picton South transmission network reinforcement project.

About the project

We’ve considered a number options before determining our preferred option. You can read about these in the options paper.

Our preferred option for securing electricity supply is a staged conversion from 66kV to 132kV, which will increase power capacity to the region and replace ageing assets in the area. This project is subject to approvals from relevant authorities following the outcome of the Regulatory Test. 

Have your say

We’re inviting you to share your thoughts on the options we’ve considered as part of the project.  Your feedback is also an important step in the Regulatory Test approval process for the Picton South transmission network reinforcement project.

Information sessions will be held in Perth and the South West to discuss all the possible options, including our preferred option. This forum provides an opportunity for anyone to ask questions and provide alternative options for consideration.

Perth Forum

When: Monday 17 February 2020, 9.30am – 11.00am

Where: Western Power Perth Office, 363 Wellington Street, Perth

South West Forum

When: Wednesday 19 February 2020, 11.00am – 12.30pm

Where: Quality Hotel Lighthouse, 2 Marlston Dr, Bunbury

Technical Rules Review

We are undertaking a review of the Technical Rules.

Since its first publication in 2007, the Rules have undergone several amendments, with the most recent in December 2016. Whilst the Rules were appropriate at the time of commencement, the energy market has changed significantly since they were first published, and the Rules are now overdue for a review. The main gaps include, lack of:

  • clarity on the roles and responsibilities of AEMO and Western Power
  • requirements to address the changing needs of the System – e.g. system strength, inertia
  • flexibility in customer connections
  • consideration for emerging technologies
  • consideration for non-traditional network or supply options (microgrids, standalone power systems)
  • consideration for the latest standards and industry practices
  • robust compliance framework
  • easier process for Rule change

The gaps are felt by customers, WP and the AEMO and its need for a review is also recognised by the wider industry including the ERA and Energy Policy WA (formerly the Public Utilities Office). As part of the Energy Transformation Strategy the Energy Transformation Implementation Unit (ETIU) will address the required changes in regulations and codes to bring efficiencies in Technical Rules governance process and the compliance framework.  Western Power is working with the ETIU and AEMO to support the changes in the Technical Rules and this review forms part of that work.

For further information on the work undertaken by the Energy Transformation Taskforce refer to the Energy Transformation Policy.

The review is undertaken in three stages:

  • Stage 1: Move Generator Performance Guidelines (GPG) to the Wholesale Electricity Market Rules

    This concerns the performance requirements for transmission connected market participating generators, moving out the Technical Rules into the Wholesale Electricity Market Rules. To be completed Mid 2020.
  • Stage 2:  Review Chapters 1 to 4 of the Technical Rules.

    The proposed date for submission to the Energy Regulation Authority (ERA) for approval is by the 30th of December 2020
  • Stage 3: Review Chapters 5 of the Technical Rules

    The proposed date for submission to the Energy Regulation Authority (ERA) for approval is by the 30th of December 2021


Western Power welcomes feedback from the public/customers on their felt experience or suggestions for improvement in relation to ‘User’ requirements in chapters 1, 3 and 4 of the Technical Rules.

Feedback can be sent to:

The closing date for input is 30 June 2020
