Underground power

We work collaboratively with the State Government, local councils and land developers to convert overhead powerlines to an underground supply where it makes economic sense to do so.

While underground power has a number of benefits for local communities such as improved power reliability and street front aesthetics, it is considerably more expensive to build than overhead powerlines.

This is especially the case where overhead lines have not yet completed their natural life cycle. Find out more about the difference between overhead and underground power.

We deliver underground power through the following initiatives:

  • State Underground Power Program (SUPP) – this program shares the cost of undergrounding power between the State Government, Western Power, local councils and property owners (find out more about SUPP's history and FAQs)
  • Retrospective Underground Power Projects (RUP) – these projects are generally funded directly by local councils or land developers

Please see the list of our underground power projects.

Note – Project timelines are subject to change.

All SUPP projects are schedule to be constructed between 2018 and 2020.

Please see table below to scheduled start dates where available. Schedules will be updated as designs are completed.
