Work is expected to begin shortly, with completion anticipated by September 2027.
The KLG project is situated around 6km south-east of Koolunga and 7km north-east of Brinkworth.
It will link to the state’s electricity grid through a 1.2km high-voltage cable connected to the 275kV Brinkworth Substation.
Owned by Equis Development, an infrastructure investor in Asia-Pacific, the KLG project has obtained all necessary planning and environmental approvals, and completed community impact assessments.

“This contract gives us great confidence that the market sees our capability and capacity to deliver a project of this size and complexity.
“We look forward to working closely with Equis to deliver the project safely, successfully and on time.”
