Several state battery schemes were designed as stop-gaps before the federal program began on 1 July 2025. Once the federal discount arrived, they wound down. At the time of writing the following are closed: the Northern Territory battery scheme, the Queensland Battery Booster, the Victorian Solar Battery Loan and the Tasmanian Energy Saver Loan. If you were waiting for one of them, here is where things stand.
What replaced them
The Cheaper Home Batteries Program gives STCs for batteries of 5 to 100 kWh usable capacity, with up to 50 kWh eligible. The battery must be CEC approved, VPP-capable and installed by an accredited installer, one per property, with new or existing solar. The installer claims the certificates and passes the value on as a discount on your invoice.
The factor is 6.8 at the time of writing, stepping down to 5.7 on 1 January 2027 and 5.2 on 1 July 2027. Since 1 May 2026 the first 14 kWh counts at 100%, 14 to 28 kWh at 60% and 28 to 50 kWh at 15%. Because the factor steps down every six months, waiting for a state scheme to return usually costs more than it saves. Try the battery STC calculator for your size.
Northern Territory
The NT scheme is closed. Territory households use the federal discount, and the installer’s claim works the same way as anywhere else. See our Northern Territory rebate page.
Queensland
The Battery Booster has closed. The federal discount stands alone, and our Queensland rebate page tracks what remains.
Victoria
The interest-free Solar Battery Loan no longer takes new applications. Victoria’s solar panel rebate is separate, with the household income cap at $150,000 since 1 July 2026. Read how this interacts with the federal discount in stacking federal and state battery offers, and our Victoria rebate page.
Tasmania
The Energy Saver Loan has closed. Tasmanian households can still claim the federal discount, and our Tasmania rebate page is the place to check for any new state offer.
Schemes that are still running
South Australia and the ACT are different stories: see the South Australian battery scheme and the ACT Sustainable Household Scheme. Western Australia’s scheme is active and VPP-required, covered in the WA residential battery scheme.
Is a battery still worth it?
That depends on your evening usage, tariff and whether you will join a VPP, not on the state scheme. Our battery worth-it answer sets out the sums.
From the desk: Do not hold off for a state scheme that has been announced but not opened. The federal factor drops on fixed dates, so a delay of one step can cost more than a small state grant returns. Always verify any new scheme on the government’s own page.
