More than 500,000 home batteries have now been installed under the Australian Government’s Cheaper Home Batteries Program, helping households and businesses store solar energy, reduce electricity bills and ease pressure on the power grid.
Australia has one of the highest rooftop solar adoption rates in the world, with more than one in three households having solar panels installed. The battery program is aimed at helping these consumers make greater use of the electricity they generate during the day by storing it for use when demand and power prices are higher.
More than three-quarters of the batteries installed through the program have been deployed in outer suburban and regional communities. The milestone was marked at a solar and battery installation business in Castle Hill, which is located in the postcode with the highest number of batteries installed under the program.
Western Sydney has recorded particularly strong growth in battery adoption. The Mitchell electorate, which ranked 108th nationally for battery uptake in 2024, has now moved to third place nationally, highlighting the rapid increase in household battery installations.
The Australian Energy Market Operator’s latest quarterly report has also highlighted the growing role of household batteries in Australia’s electricity system. Batteries can supply stored solar power to homes after sunset, reducing reliance on the grid during the evening peak. This can help lower demand and put downward pressure on electricity costs.
The rollout is also supporting local employment and businesses. Thousands of installers, small businesses and energy workers are involved in delivering battery systems across metropolitan, suburban and regional areas.
The number of accredited battery installers in Australia has more than doubled since the program began, reaching 8,846. This expansion reflects growing demand for residential energy storage and the increasing importance of batteries in Australia’s clean energy transition.
Prime Minister Anthony Albanese said the milestone demonstrated that Australian households were leading the adoption of both rooftop solar and home batteries. He said the program was helping families store low-cost solar energy generated during the day and use it when needed.
Climate Change and Energy Minister Chris Bowen said the 500,000-battery milestone represented a major achievement for households, tradespeople and small businesses. He said the program was helping consumers reduce their electricity bills, store solar energy and gain greater control over their energy use.
With rooftop solar and battery adoption continuing to expand, household energy storage is becoming an increasingly important part of Australia’s electricity system, supporting consumers while helping manage demand on the national grid.
