Underground power

WA’s electrical network including the Perth CBD, was originally constructed overhead, but over time new technology has allowed us to move the network in high density areas to underground.

When did this all start?

In 1991 the State Government made a change that saw the network for all new urban subdivisions be placed underground. Following major storms and outages in 1996, the idea of moving existing overhead networks underground heightened, and the  State Underground Power Program (SUPP) was established.

Today, there are three programs running to change the overhead network to underground power:

Network Renewal Undergrounding Pilot Program (NRUPP) – these are driven by us and target areas with a high density of aging overhead assets.

State Underground Power Program (SUPP) – the cost of undergrounding is shared between the State Government, Western Power, Local Government Authorities (LGAs) and property owners.

Retrospective Undergrounding Projects (RUP) – these are generally funded directly by LGAs or land developers.

Is my area switching to underground?

Check the list below to see if your area is moving to underground power now or in the near future. We’ll update the list with start and finish dates as projects progress.

Our guide to what’s happening in your area will help you understand what’s involved and how it may impact you. Still have questions? Read our FAQs to learn more.
