Western Power secures federal funding and constructs 18 community battery storage systems in Western Australia

Type: Development · Technology: Storage · Country: Australia · Capacity: 6.6 MW · Announced: 2026-06-15

Western Power, the state-owned utility in Western Australia, commenced construction of 18 new community battery energy storage systems with a combined 6.6 MW capacity in Perth and Bunbury under the federal government's $200 million Community Batteries for Household Solar program. The project includes 13 low-voltage batteries in Perth and five medium-voltage batteries in Bunbury, with funding of AUD 9.3 million provided by the federal government out of the total AUD 25 million project cost. The batteries will store excess rooftop solar energy during the day and release it during evening peak demand, reducing strain on local infrastructure and lowering systemwide costs. About 3,600 households will be connected across the Bunbury batteries, expected to be operational by the end of 2026, while Perth batteries are slated for completion by May 2027. The initiative builds on Western Australia's existing 45,000+ home batteries and utility-scale projects like Kwinana and Collie, aiming to enhance grid reliability and support the state's high rooftop solar uptake.
