Electricity in Western Australia
Western Australia is not part of the National Electricity Market. Its main grid is the South-West Interconnected System (SWIS) around Perth, where Synergy is the regulated monopoly retailer and Western Power runs the network; regional and remote areas are served by Horizon Power. WA runs its own Residential Battery Scheme and battery-rebate rules, so the VPP landscape here is quite different from the eastern states.
