Australia: Construction is now underway on the Clean Energy Link – North project, marking the start of Western Australia’s largest transmission upgrade in more than a decade. The state government has committed $584 M to the programme, including $342 M allocated in the 2025–26 budget for the initial works.

The project will deliver major upgrades to the northern section of the South West Interconnected System (SWIS), the network that supplies electricity from Geraldton to Albany and east to Kalgoorlie. Work includes converting 290 km of existing 132 kV transmission line to 330 kV, alongside the construction of a new double-circuit transmission line between Eneabba and Eneabba Terminal. A new 330 kV terminal will also be built next to Regans substation, enabling improved resupply capacity.

Western Power has begun construction at four key sites in Perth’s northern suburbs as part of the initial rollout. Once completed, the upgrades are expected to double capacity on some sections of the SWIS and unlock around 400 MW of existing wind energy and up to 1 GW of new renewable generation, particularly from the Mid West region.

Energy and Decarbonisation Minister Amber-Jade Sanderson said the project is essential to WA’s plan to phase out State-owned coal by 2030. She noted that the expansion will support economic growth, boost grid security and allow more renewable projects to connect to the system.

The state government reported that the Clean Energy Link – North project is progressing on schedule and is expected to be completed by the end of 2027. More than 400 jobs will be created during construction.
