Energy projects in Western Australia
Updated
Western Australia's main electricity market, the South West Interconnected System (SWIS), operates entirely separately from the eastern grid with its own rules, capacity market and dynamics. Renewable energy growth is accelerating, driven by state policy targets, falling technology costs and rising demand from energy-intensive industrial economies. Mining and resources remain the dominant load, and large industrial customers are increasingly driving new generation and storage investment by seeking firmed renewable supply.
