The Australian Government announced on 1 May 2026 that the Cheaper Home Batteries Program will receive an additional AUD$4.9 billion in funding, ensuring the incentive continues until its scheduled end date of 31 December 2030. This significant boost comes as the program undergoes a key adjustment to its Small-scale Technology Certificate (STC) structure, impacting the level of upfront discount homeowners can expect on new battery installations.
While the program’s overall funding has increased, the value of the federal battery rebate has seen a reduction from 1 May 2026, with the STC factor dropping from 8.4 to 6.8 per usable kilowatt-hour (kWh) of battery capacity. This translates to an approximate 19% decrease in the rebate amount per kWh. Furthermore, a tiered rebate model has been introduced, meaning larger batteries will receive progressively less support for capacity above 14 kWh.
Understanding the New Tiered Rebate Structure
The federal Cheaper Home Batteries Program, which initially commenced on 1 July 2025, provides an upfront discount on eligible home batteries. This discount is facilitated by installers claiming STCs on behalf of the customer. The recent changes, effective from 1 May 2026, aim to encourage what the government terms “right-sized” battery installations by adjusting the rebate based on usable capacity.
Prior to May 1, 2026, the rebate operated on a flat structure, where every eligible kWh received the same STC value, and larger batteries generally received higher overall rebates. The new tiered system significantly alters this:
New Battery Rebate Slabs (From May 1, 2026)
| Battery Capacity | Rebate Applied (STC Factor) |
|---|---|
| 0–14 kWh | 100% of STC factor (6.8) |
| 14–28 kWh | 60% of STC factor |
| 28–50 kWh | 15% of STC factor |
| Above 50 kWh | No rebate |
This means that homeowners will receive the highest rebate value on the first 14 kWh of usable battery capacity. For larger systems, the incentive per kWh decreases significantly. For example, a 10 kWh battery, which comfortably covers most Australian families’ evening and overnight usage, would receive the full rebate on its entire capacity. However, a 20 kWh battery would receive the full rebate on the first 14 kWh and a reduced 60% rebate on the remaining 6 kWh.
What This Means for Your Savings
The value of the federal rebate is now approximately AUD$252 per usable kWh for the first 14 kWh of battery capacity, assuming an STC clearing price of around AUD$37 after administrative fees. This translates to an estimated AUD$3,500 off a 14 kWh battery or AUD$2,500 off a 10 kWh battery.
“The Australian battery rebate can deliver savings of up approximately $252 per kWh of battery storage installed. For popular household batteries, the scheme can deliver savings of up to $3,800.”
It’s important to note that the STC factor is scheduled to decrease further every six months, with the next reduction locked in for 1 January 2027. This gradual phase-down means that installing a battery earlier in the program’s lifecycle will generally yield a higher upfront discount.
Who Benefits and Who is Impacted?
This revised rebate structure primarily benefits households seeking standard-sized battery systems (up to 14 kWh), which typically meet the energy storage needs of an average family. Those with higher energy demands, such as households with electric vehicles, pool pumps, or consistently high daily usage (over 25 kWh per day), may find the reduced rebate for larger capacities impacts their overall upfront cost more significantly.
The federal rebate is not means-tested and is stackable with some state-level incentives, such as those offered in New South Wales and Western Australia, allowing for potentially greater combined savings. Eligibility extends to homeowners, small businesses, and community facilities, with a limit of one battery per electricity meter.

The Broader Context of Battery Adoption
The federal government’s continued investment in the Cheaper Home Batteries Program, despite the reduced per-kWh rebate, signals a strong commitment to accelerating battery storage adoption across Australia. This aligns with broader efforts to integrate more renewable energy into the National Electricity Market (NEM) and enhance grid stability.
With over 4.4 million Australian homes and businesses having already installed solar panels, the focus is increasingly shifting towards storage solutions that allow households to maximise self-consumption of their solar generation and reduce reliance on grid electricity, especially during peak demand periods. This strategic deployment of home batteries is crucial for Australia’s transition to an 82% renewable electricity target by 2030.
For homeowners considering adding battery storage to an existing solar system, or installing a new integrated system, the federal rebate remains a substantial incentive. However, careful consideration of system sizing and the timing of installation will be critical to securing the most favourable financial outcome before further reductions occur.
