Western Australia is not connected to the national grid. Western Power runs the South West Interconnected System, from Kalbarri to Albany and Kalgoorlie, which the state government calls one of the most isolated large grids in the world, and Horizon Power runs 38 separate regional networks. Gas supplied 57.4 per cent of generation in 2025 and coal 16.4 per cent.
