Australia’s Home Energy Storage Growth Surges Past 90,000 Installations

Australia’s home energy storage sector has seen remarkable growth in recent months, marking a significant milestone in the nation’s renewable energy transition.

According to newly released data, more than 43,000 solar battery systems have been recorded under the national Small-scale Renewable Energy Scheme (SRES) since July, while an additional 50,000 residential batteries have been installed through the government’s battery rebate initiative.

Together, these programs have accelerated the adoption of home energy storage technologies, helping households and small businesses gain greater energy independence and efficiency.

Expanding National Energy Storage Capacity

Data shows an extra 23,925 residential battery installations were added since midyear, lifting the SRES total to 43,517 systems integrated with rooftop solar. Collectively, these installations provide around 825 MWh of storage capacity, with an average system size of 19 kWh per home.

The figures reflect approved and pending applications for small-scale technology certificates, offering a strong indicator of sustained momentum in the distributed energy market.

In parallel, the government’s home battery subsidy program has achieved 50,000 installations in just two months, contributing nearly 900 MWh of additional capacity—equivalent to one-quarter of the total household battery energy storage installed nationwide before 2024.

This program offers an average 30% discount on eligible systems, helping families, small businesses, and community organizations transition to cleaner, more affordable energy solutions.

Strengthening Grid Stability and Reducing Costs

The rapid expansion of home battery installations is playing a key role in easing peak-hour energy demand and supporting the stability of regional distribution networks. By storing excess solar power generated during the day, these systems enable households to reduce reliance on the grid in the evening—lowering both energy costs and emissions.

Adoption has been particularly strong in outer suburban and regional areas, with Queensland and South Australia leading the trend. Many residents have highlighted that upfront rebates have made energy storage systems far more accessible, allowing them to capture long-term savings while contributing to a more sustainable energy future.

Supporting the Clean Energy Transition

This surge in energy storage adoption underscores growing public confidence in renewable energy technology. Each new installation contributes to Australia’s broader clean energy goals by supporting energy independence, reducing grid strain, and driving forward the integration of distributed battery systems.

More detailed postcode-level data on approved SRES applications is expected to be released later this month, offering further insights into how home energy storage continues to reshape Australia’s clean energy landscape.
