Record uptake of battery installations has prompted the Federal Government to revise the Cheaper Home Batteries rebate, with confirmed changes to both funding and how the rebate will be applied.
The CHBP has become a victim of its own success, from a C&I standpoint.
While the program is funded through to 2030, the Federal Government has confirmed that rebate values will change from 1 May 2026, and current rebate settings for larger battery systems are therefore time limited.
So, for commercial customers considering batteries between 28kWh and 50kWh, current calculations which factor the rebate are only applicable until 30 April 2026.
Why the rebate is being revised now
Since launching, the Cheaper Home Batteries Program has been taken up far faster than originally anticipated. Demand has been particularly strong for larger battery systems, including systems around 20-50kWh, which draw down a disproportionate share of available funding.
This was not anticipated by the government, who designed the program initially with homeowners primarily in mind.
Early uptake data and industry analysis indicated that, under the original structure, the initial $2.3 billion allocation was on track to be fully committed well before schedule. Without intervention, this would have forced the scheme to close early.
To prevent that outcome, the Federal Government has restructured the program.
What the government has confirmed
The Federal Government has confirmed that:
- Total funding for the Cheaper Home Batteries Program has increased from $2.3 billion to approximately $7.2 billion, extending funding through to 2030
- The program will continue operating rather than closing early due to oversubscription
- Rebate calculations will change from 1 May 2026, with revised settings applied to new installations from that date
Crucially for businesses, the government has confirmed that future rebate settings will be weighted toward smaller battery systems, with reduced effective support for larger batteries, including commercial-scale systems.
How the rebate will change in practice
The confirmed changes do not involve an abrupt end to the scheme. Instead, the program is transitioning to managed settings.
In practical terms, the following outcomes are now fixed:
- Current rebate values apply only until 30 April 2026 - from 1 May 2026, revised rebate calculations will apply
- The rebate amount declines faster and more frequently (every 6 months instead of annually).
- The rebate value tapers by battery size - see table below.
battery capacity |
Rebate Before May 1 |
rebate After May 1 |
| 0–14 kWh (inclusive) | 100% of the STC factor | 100% of the STC factor |
| >14–28 kWh (inclusive) | 100% of the STC factor | 60% of the STC factor |
| >28–50 kWh (inclusive) | 100% of the STC factor | 15% of the STC factor |
What this means if you are considering a 50kWh battery
For businesses considering battery systems of 50kWh or more, timing is now of the essence.
Under current settings, the rebate can materially reduce upfront capital cost and improve payback periods. That level of support is available only for projects installed and commissioned on or before 30 April 2026.
From 1 May 2026, the same battery system will attract a lower rebate under the revised calculation method- around 57% less, in fact.
Businesses that are already assessing batteries, seeking internal approval or preparing budgets should treat 30 April 2026 as a hard installation deadline if current rebate economics are required to support the investment case.
Bottom line
The Cheaper Home Batteries Program has not been cancelled. It has been expanded.
However, the program has entered a managed phase. While total funding now sits at approximately $7.2 billion, current rebate values for commercial-scale batteries are locked in only until 30 April 2026.
For businesses where the rebate is required for project viability, acting before this date is essential.
With contract and installation lead times of several weeks required, proposals for BESS systems should be approved realistically no later than mid-March to allow sufficient time.
TLDR? These FAQs Will Help
Is the rebate available for commercial batteries?
Yes. The rebate applies to commercial battery installations, including systems of 50kWh and above.
How long do current rebate values apply?
Current rebate values apply until 30 April 2026.
What happens after that date?
From 1 May 2026, revised rebate calculations will apply, reducing the effective rebate available to larger battery systems.
Should commercial projects proceed before then?
If current rebate values are required to support the business case, projects should be installed and commissioned before 30 April 2026.
