Federal vs State Battery Rebate Schemes in Australia

Last updated on November 11, 2026

Home batteries can help households store excess rooftop solar for use in the evening, reduce reliance on grid electricity and manage exposure to changing electricity prices. However, the upfront cost can still be significant.

Australia’s main battery incentive is the Australian Government’s Cheaper Home Batteries Program. Some state and territory governments also provide additional rebates, loans or incentives for connecting batteries to a virtual power plant (VPP).

These programs are not all the same: some reduce the purchase price, some provide finance, and others reward households for allowing their battery to support the electricity grid.

This guide compares the current federal program with state and territory support available as at 10 November 2026. Program rules and funding can change, so confirm eligibility and the amount available before signing an installation contract.

Federal Battery Rebate — Cheaper Home Batteries Program

The Australian Government’s Cheaper Home Batteries Program is the main nationwide incentive for eligible small-scale battery installations. It is delivered through the Small-scale Renewable Energy Scheme (SRES) using small-scale technology certificates (STCs). In most cases, the installer or retailer applies the value as an upfront discount in the quote, although eligible customers can choose to create and trade STCs themselves through the REC Registry.

The program applies to eligible battery systems installed from 1 July 2025 and connected to a new or existing solar PV system. The system must meet the program’s technical and installation requirements.

Key federal program rules

Eligible battery systems must have between 5 kWh and 100 kWh nominal capacity.
STCs are calculated on usable capacity, with support applying to the first 50 kWh of usable capacity.
The battery must be on the Clean Energy Council’s approved battery list and installed by a Solar Accreditation Australia-accredited installer.
Eligible systems can be installed with a new solar PV system or connected to an existing compliant solar PV system.
The discount is not a fixed cash rebate. Its value depends on usable capacity, the applicable STC factor, the market value of STCs and the quote structure.
The program is available to eligible households, businesses and community organisations; it is not subject to a household income test.

Important changes from 1 May 2026

The federal government changed the way battery support is calculated from 1 May 2026. The STC factor now steps down every six months, and the support rate tapers for larger battery systems. This means older estimates such as a flat $300–$311 per usable kWh, or a guaranteed 25–30% discount for every system, should not be used as universal figures.

Battery capacity band	Share of STC factor applied	How it works
First 0–14 kWh	100%	Full applicable factor
Above 14 kWh to 28 kWh	60%	Reduced factor on this portion
Above 28 kWh to 50 kWh	15%	Lower factor on this portion
Above 50 kWh usable	No additional battery STCs	No STCs beyond the first 50 kWh usable capacity

For installations from May to December 2026, the published STC factor is 6.8. It is scheduled to fall to 5.7 for January–June 2027 and 5.2 for July–December 2027, with further reductions scheduled through 2030. The applicable factor is determined by the installation date, so the final discount should be confirmed in a current written quote.

Pros of the federal program

Available nationally, regardless of state or territory.
Can reduce the upfront cost of an eligible battery installation.
Can generally be combined with compatible state and territory incentives, subject to each program’s rules.
No household income test applies to the federal battery discount.

Important limitations

The discount amount is not guaranteed to be the same for every battery or installer.
Larger systems receive a lower support rate on capacity above 14 kWh and 28 kWh.
The STC factor reduces over time, so the value may be lower for later installation dates.
The battery and installation must meet the scheme’s technical, safety and accreditation requirements.

State and Territory Battery Incentives

State support changes more frequently than the federal program. The table below separates active household battery rebates from finance schemes, VPP payments and programs that have closed. A loan is not a rebate: it must be repaid.

Western Australia (WA)

The WA Residential Battery Scheme is an active state-level program and can be used in addition to the federal Cheaper Home Batteries Program, subject to the scheme’s eligibility conditions.

Rebate of up to $1,300 for eligible Synergy customers.
Rebate of up to $3,800 for eligible Horizon Power customers.
No-interest loans of up to $10,000 may be available to households with combined annual income below $210,000, repayable over up to 10 years.
The state rebate is based on up to 10 kWh of usable battery capacity; larger batteries do not receive a larger state rebate.
Approved battery products, accredited vendors/installers and participation in an eligible VPP product are required.

Official details: WA Residential Battery Scheme.

New South Wales (NSW)

The previous NSW household battery installation discount is no longer available for new home battery installations. NSW households should not expect a separate NSW battery purchase rebate on top of the federal discount.

The key current NSW battery incentive is the Virtual Power Plant (VPP) incentive. Eligible households and small businesses can receive an upfront incentive for connecting an eligible battery to a participating VPP provider. The amount depends on the usable battery capacity made available to the grid (up to 28 kWh), the provider and the contract. Some providers may pay the incentive upfront, in instalments or as bill credit. Additional payments for exporting stored electricity depend on the VPP agreement and are not a guaranteed government payment.

Batteries generally need to be more than 2 kWh and no larger than 50 kWh to qualify for the VPP incentive.
The incentive is claimed once per National Metering Identifier (NMI).
The battery must be connected to the grid; off-grid batteries are not eligible.
The federal Cheaper Home Batteries Program discount can be combined with the NSW VPP incentive if all requirements are met.

Official details: NSW Virtual Power Plant incentive.

The NSW battery installation information page confirms the former household battery installation discount is no longer available.

Eligible NSW homeowners may also be able to use the Home Energy Saver zero-interest loan for an approved residential battery installation. This is finance, not a rebate, and approval, eligible products and loan limits are determined by the program and finance provider. The current loan maximum is $15,000, repayable over up to 10 years. Check the participating provider’s battery eligibility before relying on this option.

See NSW Home Energy Saver loan eligibility and approved upgrades.

Victoria (VIC)

Victoria’s Solar Homes battery rebate and interest-free battery loans closed in mid-2025. They should not be advertised as currently available to new applicants. Eligible Victorian households can use the federal Cheaper Home Batteries Program for qualifying battery installations.

Victoria continues to offer other household energy-upgrade discounts, including support for rooftop solar and efficient appliances, but these should not be described as a current home battery rebate. The state also funds neighbourhood-scale battery projects, which are not individual household battery rebates.

See current household offers on Energy Victoria’s discounts and rebates page.

Queensland (QLD)

Queensland’s Battery Booster rebate program is closed to new applications. The former scheme offered rebates of up to $3,000 or $4,000 for eligible households, but those amounts are historical and should not be presented as available now. As at this review, the federal Cheaper Home Batteries Program is the main battery purchase discount for Queensland households.

Queensland Government notice: Battery Booster program closure information.

South Australia (SA)

South Australia’s Home Battery Scheme is closed and is not accepting new applications. Households considering a new battery can generally access the federal Cheaper Home Batteries Program if their system meets the eligibility requirements. Do not quote the former state subsidy or subsidy-linked loan as a currently open state battery rebate.

Official status: South Australia Home Battery Scheme closure.

Tasmania (TAS)

Tasmania’s Energy Saver Loan Scheme, which previously supported eligible energy upgrades including batteries, closed on 1 September 2025. No current broad state household battery rebate or replacement battery loan was identified in the official program information reviewed for this update. The federal Cheaper Home Batteries Program remains available to eligible Tasmanian installations.

Australian Capital Territory (ACT)

The ACT Sustainable Household Scheme offers low-interest finance for eligible home energy upgrades, including household battery storage. From 1 July 2026, eligible households can borrow up to $20,000, with a 3% interest rate and repayment terms of up to 10 years. This is a loan, not a battery rebate, and is subject to scheme and lender eligibility.

Eligible concession-card holders may qualify for separate Home Energy Support rebates for approved energy upgrades, but customers should confirm whether their proposed battery product is covered before including any rebate in a quote.

Official details: ACT Sustainable Household Scheme.

Northern Territory (NT)

The NT Home and Business Battery Scheme has reached its $6 million funding allocation and is closed to new grants. The former grant offered $400 per kWh of usable battery capacity, up to $12,000, but this is not currently available to new applicants.

The NT’s Solar for Multi-Dwellings Grant may support shared solar and battery projects in eligible apartment and strata developments. It is not a standard rebate for an individual household battery installation. Eligible NT households can still consider the federal Cheaper Home Batteries Program.

Official closure notice: NT Home and Business Battery Scheme.

Can You Combine Federal and State Battery Incentives?

In some locations, yes. The federal Cheaper Home Batteries Program is designed to work alongside compatible state and territory incentives. However, stacking depends on the specific program rules, installation date, battery size, provider and customer eligibility.

Examples include:

WA: the federal discount may be combined with the WA Residential Battery Scheme rebate and, where approved, its no-interest loan.
NSW: the federal discount may be combined with the NSW VPP incentive. Eligible customers may also explore Home Energy Saver finance for approved upgrades.
ACT: the federal discount may be combined with eligible ACT finance or concession-card support, subject to the relevant scheme rules.

Do not assume that every state loan, VPP payment or retailer offer can be stacked automatically. Confirm the combination in writing with the program administrator and installer before signing a contract.

How to Check the Actual Battery Discount

There is no single rebate amount that applies to every household battery. The federal discount is calculated using the battery’s usable capacity and the STC factor that applies on the installation date. Larger systems receive reduced support on capacity above 14 kWh and 28 kWh.

Confirm the battery model is on the Clean Energy Council approved list.
Confirm the installer is accredited by Solar Accreditation Australia.
Ask the installer to show the federal STC discount as a separate line item in the quote.
Check the usable capacity used in the calculation, not just the battery’s nominal capacity.
Ask whether any state incentive requires VPP participation, a specific retailer, an approved vendor or an application before installation.
Compare the total installed price, warranty, usable capacity, power output and expected savings—not just the advertised rebate.

Bottom Line

The federal Cheaper Home Batteries Program is the main battery discount available across Australia, but the calculation changed on 1 May 2026. It is now tiered by battery size and the STC factor is scheduled to reduce every six months.

WA currently offers the clearest additional state rebate for household batteries. NSW offers a VPP incentive rather than a new battery purchase rebate, while the ACT provides eligible households with low-interest finance. Several older state schemes in Victoria, Queensland, South Australia, Tasmania and the Northern Territory have closed.

Before purchasing a battery, check the latest official program rules and obtain a written quote that clearly separates the federal discount, any state incentive, finance and retailer/VPP payments. This avoids relying on old rebate figures or treating a repayable loan as a grant.

Frequently Asked Questions

What is the federal battery rebate in Australia?

The Cheaper Home Batteries Program is the Australian Government’s national battery discount. It is delivered through STCs and generally reduces the upfront price through the installer or retailer. Eligible batteries must meet the program’s capacity, product, solar connection and installation requirements.

How much is the federal battery rebate in 2026?

There is no single fixed amount. From 1 May 2026, the STC factor is 6.8 for May–December 2026, and the support tapers by capacity: 100% of the factor on the first 14 kWh, 60% on the portion from 14–28 kWh and 15% on the portion from 28–50 kWh. The final dollar value depends on usable capacity, STC value and installation date.

Which states currently offer an additional battery rebate?

Western Australia currently offers state rebates of up to $1,300 for eligible Synergy customers and $3,800 for eligible Horizon Power customers. NSW has a VPP incentive, not a current general household battery installation rebate. Other state and territory support is mainly finance, closed programs or project-specific support.

Can I combine the federal battery discount with a state incentive?

Potentially. The federal program can be combined with compatible state or territory schemes, but each program has its own conditions. WA’s residential scheme and NSW’s VPP incentive are examples of additional support that may be combined with the federal discount when all eligibility rules are met.

Is the NSW battery rebate still available?

The former NSW household battery installation discount is no longer available for new installations. NSW households may be eligible for the federal battery discount and the NSW VPP incentive if they connect an eligible battery to a participating provider.

Does Victoria still offer a home battery rebate?

No current Solar Homes battery rebate or interest-free battery loan is available to new applicants. The former program closed in mid-2025. Eligible Victorian installations can still access the federal Cheaper Home Batteries Program.

Is the Queensland Battery Booster rebate still open?

No. Queensland’s Battery Booster program closed to new applications. The federal Cheaper Home Batteries Program is the main battery purchase discount available to eligible Queensland households.

Do battery rebates cover installation costs?

Yes. Government battery rebates are meant to cover part of the upfront cost of installing an eligible home battery system. This includes the cost of the battery and its installation, reducing the total amount homeowners pay. However, the rebate may not cover the full installed cost, so households may still need to contribute towards the remaining amount.

Who is eligible for the federal battery discount?

Eligible households, businesses and community organisations may qualify. The battery must generally be 5–100 kWh nominal capacity, connected to a new or existing eligible solar PV system, be an approved product and be installed by an accredited installer. There is no household income test for the federal program.
