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.
Underground power has already been installed in many areas of the City 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 of the SUPP. 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:
- Manning – the area bounded by Manning Road, Kwinana Freeway, Hope Avenue and Challenger Avenue
- Collier – the area bounded by Canning Highway, Ryrie Avenue, Blamey Place and South Terrace
- 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.
The City’s vision is to have overhead power lines placed underground throughout the entire City.
