Battery Rebates in Australia: Current Offers by State and Territory
Last Updated: 25th May 2026 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
The Cheaper Home Batteries Program is a multi-billion-dollar subsidy scheme designed to reduce the cost of batteries for Australian homes and businesses. It applies to new battery systems from 5–50kWh of usable capacity that are either connected to an existing solar system or installed with a new solar system.
The federal battery rebate works in tiers: the first 14kWh of usable battery storage will receive 100% of the rebate value. The next 15-28 kWh will receive 60%, while 29-50 kWh will receive only 10%.
The amount received by all tiers reduces at the start of and midway through every year, until the scheme concludes at the end of 2030. To find out the exact dollar amount you can expect, you can use our federal battery rebate calculator.
The rebate uses STCs like the Small-scale Renewable Energy Scheme (SRES) for solar. Like that scheme, the rebate will already be applied to any quotes you get for batteries. It’s not necessary to join a VPP to get the battery price reduction, but batteries must be VPP-capable. The federal rebate can be combined with the WA state rebate. The rebate is available to homeowners, small businesses, and community facilities.
State/Territory Battery Rebates and Loans
The only state or territory battery rebate is the WA rebate. The ACT offer a zero-interest loan to purchase batteries. Meanwhile, NSW and SA will pay you extra for joining a VPP.
Here’s how they compare:
| State / Territory | Program Name | Type | Value |
|---|---|---|---|
| Western Australia | WA Residential Battery Scheme | Rebate + Zero-interest Loan | Rebate: Up to $1,300 ($3,800 Horizon area) Loan: Up to $10,000 |
| New South Wales | NSW VPP incentive | Payment for joining VPP | Up to ~$1,100 |
| South Australia | SA REPS VPP incentive | Payment for joining VPP | Up to $2,050 |
| ACT | Sustainable Household Scheme | Zero-interest Loan | Up to $15,000 |
New South Wales
Program: NSW VPP Incentive
Incentive Value: NSW will provide a payment to batteries from 2-28kWh that join a VPP. The amount varies because it’s based on certificates called PRCs (Peak Reduction Certificates), which can change in value. At the time of writing, they are worth around $60 per kWh, so the value of the certificates could range from $60-$1,680 depending on battery size. Unfortunately, the compliance and administration costs are ridiculously high, and households typically only receive around 60% of the certificate value. So even with the maximum allowed battery size of 28kWh, the most a household can expect to receive is around $1,000.
Eligibility: The battery must have from 2-28 kWh of usable capacity, be on the Clean Energy Council’s approved list, be VPP capable, have a minimum operating temperature range from -10 to 50 degrees, and have a 10 year warranty that promises it will retain at least 70% of its original capacity and also provide a minimum of 2,800kWh of output per kWh of usable storage. If the battery is not new, it must have at least 6 years remaining on its warranty. It must be on-grid and connected to solar.
Details can be found on the SolarQuotes NSW VPP payment page.

Western Australia
Program: WA Residential Battery Scheme
Rebate Value: $130 per kWh up to $1,300 for Synergy customers in the southwest of the state, and $380 per kWh up to $3,800 for Horizon Power customers in regional WA.
Loan Option: Zero-interest loans from $2,000 to $10,000 will be available to help with the purchase of batteries. These loans can also be used to cover the cost of solar if it’s installed at the same times as a battery. Households must have a combined income of under $210,000 to be eligible. Loan repayments are made over 10 years.
Eligibility: Open to all residential properties in Western Australia, including those used for home businesses.
Conditions: The batteries must:
- Have a minimum capacity of 5 kWh
- Be VPP-ready and must join a VPP
Two new VPPs will be introduced to allow for the requirement to join one:
- Battery Rewards in the southwest Synergy area, and…
- Community Wave in the Horizon area.
The scheme will provide up to 100,000 rebates. The program is being rolled out in rounds.
Contact: Full details and updates can be found on the WA Government website.
South Australia
Program: SA REPS VPP Incentive
Incentive Value: Up to $2,050 for connecting a new or existing home battery to a REPS-approved Virtual Power Plant (VPP). The payment goes directly to the household once the VPP connection is approved.
Eligibility: Battery must be installed by an accredited retailer/installer and connected to a VPP activity provider approved under the Retailer Energy Productivity Scheme. Priority-group households (e.g. concession-card holders) may receive higher per-kWh rates.
Notes: You can claim the incentive on multiple batteries at the same address, up to a combined 28 kWh of total capacity. The VPP incentive can also be claimed again when renewing a VPP contract of at least three years.
Contact: Apply through an authorised activity provider such as MAC Trade Services or check with your chosen VPP operator for current application steps.
Australian Capital Territory (ACT)
Program: Sustainable Household Scheme
Loan Value: Zero-interest loan from $2,000 to $15,000, repayable over up to 10 years.
Eligibility: Open to ACT residents for energy-efficient upgrades like battery storage, solar, and EV charging infrastructure.
Requirements: Loan capped at $15,000 for specific products. You may be required to attend an energy efficiency workshop.
Additional Rebates: Concession card holders may qualify for up to $5,000 in rebates through the Home Energy Support Program.
Process: Approved applicants receive a QR code for installation validation.
