Western Australia has passed a clean energy milestone, with more than 50,000 home batteries now installed across the state under the federal government’s Cheaper Home Batteries Program.
The total capacity added has surpassed 1.1 gigawatt-hours (GWh), allowing thousands of households and businesses to store abundant rooftop solar energy for use during peak evening demand.
The rapid adoption is being driven primarily by Perth’s outer suburban growth corridors, where families are seeking practical ways to ease cost-of-living pressures and lower electricity bills.
This surge in storage reflects the state’s record-breaking appetite for solar power. In the second quarter of 2026, the state added over 110 megawatts (MW) of new rooftop solar capacity, enough to power 25,000 homes and setting a new state record.
“Australia is a solar nation, and these latest figures show that we’re rapidly becoming a home battery nation too,” said Federal Climate Change and Energy Minister Chris Bowen.
“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.”
The national initiative complements the local WA Residential Battery Scheme, delivering joint state and federal support to lower upfront costs for consumers.
To extend benefits to non-solar households, the government is also expanding shared energy infrastructure. Five community batteries are currently operational across WA, with 18 more set to deploy over the next 12 months.
Furthermore, 10 regional projects under the Capacity Investment Scheme will soon add 1.9 gigawatts of renewable generation and 482 megawatts of grid-scale battery storage.
“This is what building a State of Energy looks like: lower bills, cleaner energy and a stronger grid for everyone,” said WA Minister for Energy and Decarbonisation Amber-Jade Sanderson.
“WA has an abundance of solar and we know solar panels and home batteries are putting real downward pressure on power bills.”
