Completed underground power projects

View the various locations the State Underground Power Program has upgraded since it's inception in 1994.

There is an estimated 55 per cent of houses in the Perth metropolitan area that now have underground power. While property developers must ensure underground electricity supply is provided in new sub-divisions, approximately 370,000 homes in Perth and 90,000 homes in regional urban areas are still connected to Western Power’s overhead distribution system. The Program is very popular with local governments, and projects are awarded through competitive rounds similar to a public tender (subject to a budget for each funding round). Eighty-five projects have been completed under the program, providing underground distribution connections to over 86,000 properties.
