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.
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.
The Federal Government has confirmed that:
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.
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:
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 |
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.
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.
Yes. The rebate applies to commercial battery installations, including systems of 50kWh and above.
Current rebate values apply until 30 April 2026.
From 1 May 2026, revised rebate calculations will apply, reducing the effective rebate available to larger battery systems.
If current rebate values are required to support the business case, projects should be installed and commissioned before 30 April 2026.
