Underground Power Project Areas (WP-047)

Western Power is continually renewing and upgrading the distribution overhead network when assets are coming to the end of their service life.

Traditionally, the work involves like-for-like replacement of these assets, however when identified as beneficial to the community and cost effective to do so, Western Power is installing electrical infrastructure below ground to improved safety and reduce the likelihood of outages.

Western Power currently manages three programs converting the overhead network to underground power.

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

• Network Renewal Undergrounding Program Pilot (NRUPP) – driven by Western Power to target areas with a high density of aging overhead assets.

• Customer Funded / Retrospective Undergrounding Projects (RUP) – funded by Local Government Authorities (LGAs) or land developers as part of a new residential connection.
