Western Australia runs a state battery incentive for households in addition to the national program. It is separate from the federal STC rebate, and the two have been designed to be used together.
What it is
The WA Residential Battery Scheme gives eligible households a rebate for installing a home battery. It has been reported as a per-kWh rebate that differs by network area, with a larger component in the Horizon Power regions, and with interest-free finance available to some households. Because amounts, income tests and deadlines have changed more than once, we are not quoting figures here. Check the WA Government energy pages and your network operator for the terms in force when you buy.
How it differs from the federal rebate
The federal rebate pays STCs for a battery, with the factor of 6.8 in 2026 and the size tiers that began on 1 May 2026. The WA scheme is a state rebate, paid under its own rules and administered separately. The federal part is the same wherever you live, while the WA part depends on where in the state you are.
What to check
- Whether the scheme is open to new applications, and any funding cap.
- Whether the battery and installer must be on a state list as well as the CEC list.
- How the rebate is paid: upfront discount, claim after install or credit.
- Any income test, particularly for finance.
- The VPP requirement and who will operate it.
Questions to ask your installer
Ask whether they are registered for the WA scheme, whether the quote already includes the state rebate and how it will be paid, and what happens if funding closes before your application is processed. A good installer will know the answers and will put them in writing.
