Battery Rebates in Australia: Current Offers by State and Territory
Last Updated: 1st Mar 2025 By Finn Peacock, Chartered Electrical Engineer, Fact Checked By Ronald Brakels
This page covers current rebates, grants, and interest-free loans available across Australian states and territories that make battery storage systems more affordable and improve payback times.
Federal Battery Rebates
No federal battery rebate currently exists, but some states and territories offer rebates and loans.
State/Territory Battery Rebates and Loans
At the moment, the only states or territories offering any rebates, grants, or loans are the NT, NSW, VIC and the ACT.
Here’s how they compare:
| State / Territory | Program Name | Type | Value |
|---|---|---|---|
| Northern Territory | Home and Business Battery Scheme | Grant | Up to $12,000 |
| New South Wales | NSW Solar Battery “Rebate” | Rebate | Up to ~$4,470 (Varies by PRCs) |
| Victoria | Victorian Solar Battery Loan Scheme | Zero-interest Loan | Up to $8,800 |
| ACT | Sustainable Household Scheme | Zero-interest Loan | Up to $15,000 |
Northern Territory
Program: Home and Business Battery Scheme
Grant Value: $400 per kWh of usable battery capacity, up to $12,000.
Eligibility: Open to NT homeowners, registered businesses, and not-for-profits. Only one application per property and per homeowner. The property can be owner-occupied or an investment.
Key Conditions: Battery systems must be on the CEC approved list. Batteries must also be VPP capable and the NT Department of Mining and Energy can disapprove any it doesn’t think meet this criteria. If a household is still receiving the premium solar feed-in tariff, getting a grant will reduce it to the standard tariff.
Application Process:
- Check eligibility via terms and conditions.
- Get quotes from certified installers.
- Apply online through GrantsNT.
Eligible works must start after approval and be completed within six months. The NT Government will pay voucher amounts directly to installers.

Example
Payback Period: An 11.04 kWh BYD Battery Box HVM can receive a $4,416 grant (11.04 kWh x $400). If it’s installed cost would have been $12,000 this will reduce to it to $7,584. In a best case situation, this will cause its payback periods to fall from With the fastest possible payback period drops from 16.7 years to 10.5 years. As the battery’s warranty will end after 8.9 years in this when used this way, even in the best possible situation it won’t manage to pay for itself within its warranty period.
Savings Breakdown: The flat tariff in NT, which is what most households pay, is 29.21c. The solar feed-in tariff is 9.33c. Assuming a 90% roundtrip battery efficiency, a home will lose 10.4c of feed in tariff for every kWh of of electricity they use from their battery. This makes the savings from using battery energy 18.8c per kWh.
Annual Savings: Based on these figures, the maximum possible annual savings with an 11 kWh battery is about $720, assuming minimal battery degradation, the battery is fully charged with solar daily, and 95% of its full usable capacity is discharged every day.

New South Wales
Program: NSW Solar Battery “Rebate” under the Peak Demand Reduction Scheme (PDRS)
Rebate Value: Varies based on Peak Reduction Certificates (PRCs) and battery capacity. Additional certificates issued for VPP connection. For example, a 10 kWh battery could have its price reduced by around $1,500 and could receive around another payment of around $230 for joining a VPP. After three years a second payment for being part of a VPP can be received, which may be a similar amount.
The value of a PRC can vary and, because of administration and compliance costs, households do not receive their full value off the price of a battery. In February 2025 each PRC lowered battery costs for customers by around $1.90.
Eligibility: PRC amount depends on factors like battery size, DNSP, and VPP connection.
Process: Use the NSW Battery Rebate Calculator for estimates and work with installers registered as Accredited Certificate Suppliers (ACPs).
Important Notes: Only new batteries (not existing) qualify for PRCs, but existing batteries can get PRCs for joining a VPP, but only if they have at least six years left on their manufacturer’s warranty. To be eligible, most batteries would have to have been installed within the past four years.
Contact: Visit the NSW Government website or consult with SolarQuotes for details on VPP compatibility.
Example
Payback Period: A Powerwall 2 or 3 installed in Paramatta, which is in the Endeavour Network, will receive 1088 PRCs. Assuming the PRCs lower the cost to the customer by $1.90 each, the total reduction will be $2,067. If the installed price would have been $15,500 this will lower it to $13,433. If a VPP is joined, there will be an additional payment of around $313, lowering the cost to $13,120. With these savings, in a best case situation, the payback period drops from 7.5 years to 6.5 years, or 6.3 years with VPP participation. While a best case situation isn’t possible for normal households, those with above average evening electricity consumption can have batteries pay for themselves well before the end of their warranties.
Savings Breakdown: Time-of-use (ToU) tariffs in NSW charge significantly higher rates during evening peak periods, sometimes exceeding 50 cents per kWh. Assuming a 50c peak tariff, discharging 1 kWh of battery energy saves 50c minus the charging cost. With a 5c solar feed-in tariff and 90% roundtrip efficiency, charging the battery costs about 5.6c/kWh. This makes battery savings during the peak period 44.4c/kWh (50c – 5.6c = 44.4c).
Annual Savings: Assuming the 13.5 kWh Powerwall is fully charged with solar every day and discharges 95% of its full capacity (12.8 kWh) each evening at peak rates, annual savings can reach $2,078. This estimate assumes minimal capacity loss, full daily utilisation, and optimal conditions.
