Act before May 1, 2026: Tiered rebates reduce benefits for batteries over 14kWh
What is the Cheaper Home Batteries Program?
The Cheaper Home Batteries program is the Australian Government's $7.2 billion federal battery rebate initiative (expanded from $2.3B in December 2025). It provides approximately $300 per kWh discount (~30% off) on eligible home battery storage systems when installed by a CEC-accredited installer.
Important: From May 1, 2026, the program introduces tiered rebates. The first 14kWh receives 100% of the STC factor, 14-28kWh receives 60%, and 28-50kWh receives just 15%. Installing before May 1, 2026 locks in higher rebates for larger batteries.

Federal Battery Rebate FAQ
helpWhat is the federal battery rebate?
The federal battery rebate is officially called the "Cheaper Home Batteries" program. It provides approximately $300 per kWh (~30% off) on eligible home battery storage systems. The program runs through 2030, but rebate structure changes on May 1, 2026 when tiered rates reduce benefits for batteries over 14kWh.
helpHow much can I save with the Cheaper Home Batteries program?
The program offers approximately $300 per kWh before May 1, 2026. For a typical 10kWh battery, this means savings of around $3,000. A 13.5kWh Tesla Powerwall 3 receives $4,000-$5,000. After May 1, 2026, tiered rates apply: first 14kWh gets 100% of STC factor, 14-28kWh gets 60%, and 28-50kWh gets just 15%.
helpWho is eligible for the federal battery rebate?
