Future energy demand across the Pilbara continues to grow, requiring investment in critical infrastructure to strengthen network reliability and support long-term energy security.
To support this demand, the Western Australian Government invested more than $23 million, through Horizon Power, to upgrade the 132kV Transmission Line between Karratha and Dampier.
The transmission line forms a critical part of the Pilbara electricity network, connecting the Karratha Terminal Substation to the Dampier Substation and supporting the North West Interconnected System (NWIS).
The project focused on upgrading ageing infrastructure while improving long-term network reliability and visual amenity outcomes.
Genus was engaged to deliver the design, construction and commissioning of the transmission line upgrade.
The project involved replacement of ageing infrastructure, undergrounding sections of the line and reconfiguring the transmission corridor to improve network performance and reduce infrastructure footprint.
The upgrade also delivered improvements to town aesthetics through significant reductions in pole numbers.

The project involved replacement and upgrade works across the existing transmission corridor.
The scope includes:
The project drew on Genus’ capabilities across design, construction and commissioning delivery.
Commissioning of the 132kV Transmission Line was completed in November 2020, marking successful completion of the project.
The upgrade reinforced ageing infrastructure and strengthened security of supply across the North West Interconnected System (NWIS), supporting future energy demand across the Pilbara.
The works also improved local amenity through the removal of more than 200 poles from the corridor.
