The State Underground Power Program (SUPP) is a State Government initiative administered by the Public Utilities Office (PUO) at the Department of Finance. It involves placing the majority of overhead power lines in established areas underground. The Program is a partnership between the State Government, Western Power and local governments.
City of South Perth SUPP
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.
The last underground power project in the City was Salter Point, which commenced in January 2011.
In December 2015, submissions were invited from local governments interested in participating in Round Six and the City submitted all remaining six areas for assessment. In January 2017, it was announced that funding had been secured for three SUPP projects within the City - Manning, Collier Park and South Perth.
Construction will progress in the following order:
- Manning – all of the area bounded by Manning Road, Kwinana Freeway, Hope Avenue and Challenger Avenue
- Collier – all of the area bounded by Canning Highway, Ryrie Avenue, Blamey Place and South Terrace
- South Perth – all of the area bounded by Douglas Avenue, Canning Highway, Hovia Terrace and Mill Point Road.
Approval has now also been received for the area knows as Hurlingham, which will be included within the South Perth project.
The cost to property owners is yet to be determined.
Preliminary design work will commence in July 2018 for the Manning and Collier areas with the South Perth project following in the fourth quarter of 2018. Once designs have been finalised, anticipated construction start dates will be determined.
It is anticipated that construction will commence mid 2019 with the aim of completion of the overall project by the end of 2022.
