en.Wedoany.com Reported - Western Power has recently commenced construction of 18 community battery energy storage systems in Perth and Bunbury, located in southwestern Western Australia, with a total storage capacity of 6.6 MW. The federal government's "Community Batteries for Household Solar program" provided approximately AUD 9.3 million in funding for this project, which has an overall budget of AUD 25 million. The program plans to deploy 400 batteries nationwide.

Among these batteries, 13 low-voltage units are installed in the Perth metropolitan area, while 5 medium-voltage units are deployed in Bunbury. Western Australia's Energy Minister, Amber-Jade Sanderson, stated that the sites were selected primarily in areas with high rooftop solar penetration to alleviate grid management pressure. She noted that Western Australia leads the nation in rooftop solar adoption, and community batteries, as shared storage facilities, can absorb excess solar energy during the day and release it back to the local grid during peak demand periods, particularly at night, thereby reducing infrastructure burden, lowering system-level costs, and improving power supply reliability. In terms of access scale, each battery in Perth serves approximately 130 households, while the five larger batteries in Bunbury collectively cover around 3,600 households. The Bunbury project is expected to be operational by the end of this year, while the Perth metropolitan batteries are planned to be commissioned by May 2027. Federal Assistant Minister for Energy, Josh Wilson, stated that these new batteries will strengthen grid capacity, which has already been supported by over 45,000 batteries installed in Western Australian homes, five community batteries already operational in Perth, and utility-scale projects such as those in Kwinana and Collie. He noted that these 18 community batteries will help reduce grid expenditure and drive the growth of renewable energy generation.
