Battery Costs, Rebates and 2026 Rules
State battery rebates and incentives in 2026: NSW, Victoria, WA, ACT and the rest compared
Which state and territory battery incentives are open in October 2026 — the NSW VPP incentive, WA Residential Battery Scheme, Victorian loans, ACT loans — and how they stack with the federal discount.
As at October 2026, only a few state and territory battery incentives are open, and most are linked to joining a virtual power plant (VPP). NSW closed its battery installation discount to batteries installed after 30 June 2025, but its VPP incentive remains open and can be combined with the federal Cheaper Home Batteries discount. Western Australia's Residential Battery Scheme offers rebates of up to $1,300 for Synergy customers and $3,800 for Horizon Power customers, plus no-interest loans up to $10,000 for eligible households, on condition you join your retailer's VPP. Victoria's Solar Homes battery loans are closed. The ACT offers 3% loans through its Sustainable Household Scheme. Other states and the Northern Territory have no open dedicated battery rebate that we could find on official pages. Everything below was checked on official pages in October 2026; schemes change at short notice, so confirm before you sign.
For how the federal discount itself works, read the 2026 battery rebate overview.

New South Wales
The NSW Government's battery page says the NSW battery installation discount is no longer available to home and business owners and that installations had to be completed before 1 July 2025. Because NSW Peak Demand Reduction Scheme rules do not allow incentives for batteries that generate SRES certificates, you cannot take both the old NSW discount and the federal discount for the same battery. Anyone who installed between 1 November 2024 and 30 June 2025 could not claim both.
The VPP incentive is a separate payment for connecting a battery to a VPP. According to the NSW Climate and Energy Action page (updated 31 August 2026):
- Households and small businesses in NSW with a battery of more than 2 kWh and up to 50 kWh can apply; from 1 July 2026 batteries up to 50 kWh are eligible
- The upfront amount depends on the battery's usable capacity available to the grid, up to 28 kWh — a battery with 28 kWh available receives a larger incentive than a smaller one
- The amount varies by VPP provider, contract terms and timing; there is no fixed dollar figure on the page
- It is paid by the provider as a lump sum, in instalments or as bill credits
- You sign a nomination form and the provider's contract; a cooling-off period applies
- One claim per NMI; not available for off-grid batteries or batteries at apartment buildings (which have their own incentive)
- Batteries installed under the federal program can qualify
Because the payment is set by each VPP provider, compare several VPP offers on the total package: upfront incentive, ongoing credits, the retail plan you must take, and any exit fee. See virtual power plants explained.
Victoria
Solar Victoria's battery loan page (updated 16 April 2026) states that it is no longer taking applications for interest-free solar battery loans, and points households to the federal Cheaper Home Batteries Program, which "opened on 1 July 2025". Existing borrowers keep repaying under the original terms; Solar Victoria offers hardship support.
For solar panels, Solar Victoria still offers rebates with an optional interest-free loan for eligible households. Its homepage notes a combined household income threshold of $150,000 a year for solar panel and hot water rebates from 1 July 2026, and that support for households installing solar PV moves into the Victorian Energy Upgrades program from 1 July 2027. Check the current conditions on solar.vic.gov.au.
Western Australia
The WA Government's Residential Battery Scheme page (updated 15 October 2026) sets out:
| Feature | Detail |
|---|---|
| Rebate | Up to $1,300 (Synergy customers) or up to $3,800 (Horizon Power customers) |
| Basis | Maximums based on 10 kWh usable capacity; larger batteries can take part but get the same maximum |
| Loan | No-interest loan up to $10,000, repayable over up to 10 years, for combined household income under $210,000 |
| Battery | New, VPP-capable, on the Synergy or Horizon Power Supported Solutions List for your area |
| Installer | Accredited and listed in the scheme's vendor directory |
| VPP | You must commit to your retailer's VPP product |
| Payment | Usually an upfront discount paid to the vendor |
| Duration | Until 100,000 rebates are distributed; currently expected to 2027 |
The WA rebate sits on top of the federal discount. For a 10 kWh battery installed in late 2026 by a Synergy customer, an illustrative stack would be about 68 STCs × $36 = $2,448 federal plus up to $1,300 state, roughly $3,748 in total.
ACT, Queensland, South Australia, Tasmania and the Northern Territory
- ACT: the Sustainable Household Scheme offers loans at 3% interest with up to 10 years to repay, for eligible energy products including home batteries. The ACT Government's scheme page lists loans from $2,000 and says a maximum loan limit of $20,000 applies to all products for new applicants from 1 July 2026 (it was $15,000). Check current eligibility and terms on the ACT Government's Climate Choices site.
- South Australia: the former Home Battery Scheme has ended; the SA Department for Energy and Mining says it is closed to new applications. SA households rely on the federal discount and any VPP offers from retailers (some are offered under the state's Retailer Energy Productivity Scheme).
- Queensland, Tasmania and the Northern Territory: no dedicated household battery rebate open as at October 2026 was found on official pages. Past programs have closed: Queensland's Battery Booster rebate (the Queensland Government says it has closed), Tasmania's Energy Saver Loan Scheme (closed in 2025 when funding was used up) and the NT Home and Business Battery Scheme (listed on business.gov.au as closed to applications). Check your state energy department for new announcements.
How to stack incentives safely
- Federal first. Confirm the battery, inverter and installer meet the federal STC rules; most state schemes assume this.
- Check exclusions. A state scheme may exclude batteries that already create STCs (as NSW's old installation discount did) or require a specific product list (as WA's does).
- Separate the VPP contract. In NSW and WA the incentive depends on a VPP agreement. Read its term, exit fees and discharge rules.
- Get each incentive itemised. Your quote should show the gross price, the STC discount and each state incentive separately. Use the quote checklist.
FAQ
Can I get both the NSW VPP incentive and the federal discount?
Yes. The NSW Government says the VPP incentive can be combined with the federal battery discount, provided you meet the VPP incentive's own conditions.
Is Victoria planning a new battery rebate?
No new household battery rebate was listed on Solar Victoria's site when we checked in October 2026. Watch solar.vic.gov.au for changes.
I am renting. Can I get a state incentive?
Most schemes require the property owner's consent, and some require owner-occupiers. Talk to your landlord and check each scheme's eligibility page.
