Underground Power

The State Underground Power Program (SUPP) is an initiative that replaces overhead power lines in established areas with underground power infrastructure. The Program is a partnership between the State Government, Western Power and local government and is administered by the Public Utilities Office (PUO). 

Local governments can nominate areas to be converted to underground power. Each nomination is assessed against social, economic and technical criteria by the SUPP steering committee.

The City’s vision is to have overhead power lines placed underground throughout the entire city. 

Underground power has already been installed in the following areas under previous SUPP rounds:

  • Como – Round One
  • South Perth (majority of suburb) - Round Two
  • Como east – Round Three
  • Salter Point – Round Five

In April 2016, submissions were invited from local governments interested in participating in Round Six. The City submitted all remaining six areas for assessment – South Perth, Manning, Collier, Kensington east, Kensington west and Hurlingham. In January 2017, it was announced that funding had been secured for three of these projects - Manning, Collier and South Perth. 

Construction will progress in the following order:

  • Collier – the area bounded by Canning Highway, Ryrie Avenue, Blamey Place and South Terrace
  • Manning – the area bounded by Manning Road, Kwinana Freeway, Hope Avenue and Challenger Avenue
  • South Perth – the area bounded by Douglas Avenue, Canning Highway, Hovia Terrace and Mill Point Road.  

The area known as Hurlingham, which is bounded by Ellam Street, Douglas Avenue and Mill Point Road does not meet the SUPP criteria and would not qualify for underground power as part of the SUPP program. The City was successful in seeking approval for the area to be included with the South Perth project as a Retrospective Underground Power Project (RUP) to benefit from the economies of scale of being part of the bigger project area. More details about this project will be available soon.

Construction is scheduled to commence in Collier in December/January 2020 with the Manning project area to follow in early 2021. Residents and ratepayers living within the project area will be notified once the timeline has been finalised.

Why are we getting underground power? When were property owners asked if they want underground power? How were the Round Six projects selected? What are the benefits of underground power? What if I don't want underground power? What if my land is vacant? Why do I have to pay for underground power? Why should I have to contribute to the replacement of Western Power infrastructure? How much will my underground power charge be? Is the cost for my suburb different to other suburbs? What pensioner and senior rebates are available? What if I can’t afford to pay the Underground Power invoice when I receive it? What happens to any outstanding monies owed on my property if I sell my house? When will I get underground power? How will the project be implemented? What will happen to my verge when underground power is installed? Does the cost include the connection to my meter box? I already have underground power from the front of my property to my meter box, do I still have to pay? Will all the old overhead power lines and poles be removed? When will I be able to find out more information?
