Western Australia has exceeded 50,000 home battery installations, delivering more than 1.1 GWh of household storage, while April–June 2026 saw over 110 MW of new rooftop solar (roughly 25,000 homes' worth). Outer suburban Perth has driven much of the growth, and governments are rolling out community and grid-scale batteries — including projects delivering 1.9 GW of renewables and 482 MW of battery capacity in regional WA — to strengthen reliability and reduce costs.

Western Australia has passed a major clean-energy milestone: more than 50,000 home battery installations under the federal Cheaper Home Batteries Program, delivering over 1.1 gigawatt-hours (GWh) of household storage, according to a Mirage News release.
During the April–June 2026 quarter, households also added more than 110 megawatts (MW) of new rooftop solar — roughly the capacity needed to power about 25,000 homes — illustrating how residential solar and storage are growing together.
Where Uptake Is Strongest
Much of the uptake has come from outer suburban communities around Perth, signaling that home batteries are moving from a niche technology to a mainstream household purchase. Officials say that pairing batteries with rooftop solar allows households to store daytime generation for use after sunset, cutting energy bills and reducing reliance on the grid.
Community And Grid-Scale Support
Households installing storage alongside rooftop solar can access both the federal Cheaper Home Batteries Program and Western Australia's Residential Battery Scheme. Governments are also supporting larger projects so Australians without household solar can benefit from shared systems.
At present, five community batteries in WA provide 2.8 megawatt-hours (MWh) of storage, with a further 18 set to come online. Those systems help balance local demand and support neighbourhoods as rooftop solar uptake grows.
Under the Australian Government's Capacity Investment Scheme, ten new projects in regional WA are expected to deliver around 1.9 gigawatts (GW) of renewables and 482 MW of battery capacity, helping build larger-scale reliability and storage infrastructure.
Voices From Government
Assistant Minister for Climate Change and Energy Josh Wilson said the figure was "a significant milestone" that shows how strongly Western Australians have embraced home energy storage.
Minister for Climate Change and Energy Chris Bowen added: "Every battery helps cut power bills, reduces pressure on the grid during peak periods and helps put downward pressure on wholesale electricity prices for all consumers, while helping build a stronger and more reliable electricity system."
WA Minister for Energy and Decarbonisation Amber-Jade Sanderson described the rollout as an example of "building a State of Energy: lower bills, cleaner energy and a stronger grid for everyone." Wilson also noted that the government is ensuring "the big-ticket items like community batteries and grid-scale storage are built too."
Options For Homeowners
Homeowners exploring battery options can use free online comparison tools such as EnergySage, which partners with installer Qmerit to provide competitive installation estimates. For more budget-friendly backup, some companies (for example, Pila) offer plug-and-play batteries that cost a fraction of full whole-home backup systems.
Overall, the combined growth of rooftop solar and residential batteries is positioned to improve household resilience during outages, lower energy costs for consumers and contribute to a more reliable, lower-emissions electricity system.
