Australia’s home energy storage uptake continues to grow at roughly three times the rate it did in July 2025, when federal Labor’s Cheaper Home Batteries scheme was first launched, with new monthly data showing a market that is “quickly recovering” from having the brakes slammed on in May.
By the end of July 2026, a total of more than 490,000 home battery systems had been installed through the rebate, adding upwards of 13 gigawatt-hours (GWh) of storage behind the meter and putting the booming market on track to notch up half a million installations this month.
And while federal energy minister Chris Bowen recently confirmed there are still roughly 2,000 new systems being installed every week, the volume of registered capacity has been levelling off since May, when the scheme was adjusted to reduce the discount being offered and to incentivise smaller systems.
According to the latest market update from SunWiz, registered home energy storage system (ESS) volume came in at 0.96 gigawatt-hours (GWh) or 960 megawatt-hours (MWh) in July, more or less flat against June’s numbers and continuing a steep decline from April’s 2.43 GWh peak.
