We’re building a new 26.5km overhead 132kV transmission line to increase the flow of energy between Perth and the Mid West region enabling the connection of more wind and solar generation. The project is strengthening the backbone of the network for cleaner reliable and affordable energy system for all.

Starting at the intersection of Wanneroo Road and Ocean Reef Road, the new line will head east along Ocean Reef Road and travel up Sydney Road to Hawkins Road, then north to Boundary Road before entering Neerabup Terminal (in Pinjar) on Neaves Road.

This alignment was chosen after closely assessing multiple options and working with local and State Government agencies to align with long term plans for the area, including the East Wanneroo District Structure Plan. The route makes use of existing infrastructure and road reserves to minimise overall community impact.

Detailed design is underway with construction expected to begin in 2026 and completed in 2027.

We’re committed to keeping you informed every step of the way and will share construction impacts as they become known and will work to minimise any disruption.
