What is the State Underground Power Program (SUPP)?
SUPP is a State Government initiative that was set up to convert overhead power underground.
Under the current guidelines, Local Government Authorities (LGAs) can nominate areas to be converted.
Projects fall under two categories:
After significant damage was caused to our overhead network during severe storms in 1994, the State Government established the SUPP. We manage the program together with Energy Policy WA (EPWA) and the WA Local Government Association.
Pilot projects involving around 7,000 households were successfully carried out in Applecross, Albany, Cottesloe/Claremont and Wembley between 1996 and 1999.
As the program continued, Local Government Authorities (LGAs) nominated areas, and the first projects selected became Round 1 of the SUPP. The program is still running with 17 areas currently being rolled out for Round 6.
Who’s responsible for managing the State Underground Power Program (SUPP)?
SUPP is managed by Energy Policy WA and includes a Steering Committee made up of representatives from Energy Policy WA (EPWA), the WA Local Government Association (WALGA), Western Power and Local Government Authorities (LGAs). We manage the development and delivery of each project.
