Only four jurisdictions have a state battery rebate or finance program that stacks with the federal rebate in 2026: NSW, WA, ACT, and the federal-only states.
The federal Cheaper Home Batteries Program applies in every Australian postcode and is the foundation of any 2026 battery rebate plan. It's worth roughly $3,300 off a 10 kWh battery in most states, or up to $4,200 in NT (Zone 1).
On top of the federal rebate, four jurisdictions have active state-level battery stacks: NSW (PDRS VPP top-up up to $1,500), WA (Residential Battery Scheme up to $5,000 Synergy or $7,500 Horizon Power), and ACT (Sustainable Household Scheme interest-free loan up to $15,000).
Victoria, South Australia, Queensland, Tasmania, and Northern Territory are federal-only as of mid-2026. Their previous state schemes (Solar Victoria battery loan, SA Home Battery Scheme, QLD Battery Booster, NT Home and Business Battery Scheme) have all closed or hit funding caps.
Here's exactly how each stack works, with side-by-side comparison and worked $0-upfront examples.

NSW: federal + PDRS VPP up to $4,800
NSW is the second-most generous state for battery rebates after WA. The NSW Peak Demand Reduction Scheme (PDRS) VPP incentive stacks with the federal rebate for up to $1,500 additional savings on a 10 kWh battery.
VPP enrolment is required for the state portion. Common participating retailers include Origin Loop, AGL VPP, and Energy Locals.

WA: federal + RBS up to $5,000 or $7,500
WA is the most generous state in the country for battery rebates. The WA Residential Battery Scheme stacks with the federal rebate for up to $5,000 combined for Synergy customers, or up to $7,500 combined for Horizon Power customers, on the first 10 kWh of usable capacity.
The 100,000-system allocation cap is the biggest urgency lever in the country. Once it closes, the state piece ends.

ACT: federal + $15,000 interest-free loan
The ACT Sustainable Household Scheme isn't strictly a rebate. It's an interest-free loan up to $15,000 over 10 years that stacks on top of the federal rebate to cover the post-rebate cost of the install. Most ACT households end up cash-flow-positive from month one because the bill savings exceed the loan repayment.

Federal-only states (VIC, SA, QLD, TAS, NT)
Victoria: Battery Rebate VIC 2026. Solar Victoria battery loan closed May 2025. Federal only.
South Australia: Battery Rebate SA 2026. Home Battery Scheme closed September 2022. Federal only, but strong retailer competition and SA's high retail prices make payback fastest of any federal-only state.
Queensland: Battery Rebate QLD 2026. Battery Booster closed when federal launched. QLD is STC Zone 2, so per-kWh federal rebate is larger than other federal-only states.
Tasmania: Battery Rebate TAS 2026. No state battery rebate. New retailer entry (Solstice, CovaU, 1st Energy) in 2025 transformed FiT economics.
Northern Territory: Battery Rebate NT 2026. State scheme funding cap reached. NT is STC Zone 1, so federal rebate is largest in the country, but shipping and cyclone hardware add costs.

Frequently asked questions
Four jurisdictions: NSW (PDRS VPP top-up up to $1,500), WA (Residential Battery Scheme up to $5,000 for Synergy customers or $7,500 for Horizon Power customers), and ACT (Sustainable Household Scheme interest-free loan up to $15,000). VIC, SA, QLD, TAS, and NT are federal-only as of mid-2026.
The largest single combined rebate is in WA for Horizon Power customers: up to $7,500 combined federal + state on the first 10 kWh of usable battery capacity. Outside of WA, NSW (up to $4,800 combined for a 10 kWh battery) is the next largest.
NSW PDRS and WA RBS both require VPP enrolment for the state portion. ACT SHS does not require VPP. Federal Cheaper Home Batteries Program never requires VPP enrolment, though some retailers offer VPP sign-up bonuses that complement the federal rebate.
Yes, the federal Cheaper Home Batteries Program allows one rebate per property (each property must have its own electricity meter). State stacks generally follow the same rule. So a household owning two NSW properties can claim federal + PDRS at each.
No state announcement has been made for VIC, SA, QLD, TAS, or NT to reintroduce a state battery rebate as of mid-2026. The federal Cheaper Home Batteries Program (now funded at $7.2 billion through 2030) is positioned as the main national subsidy mechanism.
