New Details Revealed About WA Home Battery Rebate

WA Residential Battery Scheme

Now the dust has settled after Western Australia’s state election, a little more detail has provided about the Cook Government’s upcoming WA Residential Battery Scheme.

Among WA Labor’s pledges in the lead-up to the state election was a $387 million program to provide non-means-tested home battery rebates of up to $5,000 for Synergy customers and up to $7,500 for Horizon Power customers, along with a means-tested no-interest loan option. The rebate will be available for residential properties in Western Australia, including home business customers.

On Wednesday afternoon, further details were published by the WA Department of Energy, Mines, Industry Regulation and Safety; but there will be more guidelines to come.

The scheme is to be rolled out in several rounds, with the first commencing on or before 1 July 2025. It will be administered by a yet un-named third-party service provider with a track record of delivery of similar schemes.

The rebate for Synergy customers will be $500 per kilowatt- hour and $750 per kilowatt-hour for Horizon Power customers for up to 10 kWh of battery capacity.

Battery System Eligibility

At this point the only eligibility requirements are:

Additional minimum standards and system warranty provisions will apply, which are to be developed in consultation with industry.

No-Interest Loans Can Incorporate Solar Panels

New, additional and replacement solar panels will also be eligible for no-interest loans in situations where installation is occurring as part of a solar + storage package purchase. Loan eligibility will be limited to households below a specified income threshold, with both minimum solar system size and income threshold yet to be determined.

The minimum loan amount will be $2,000 and the maximum, $10,000; which Premier Cook previously said can be repaid over 10 years.

For Installers And Retailers

Accreditation and compliance arrangements are still to be fleshed out and will be developed in consultation with industry, but here’s what we know so far – which isn’t much.

First, retailers and installers wanting to participate in the scheme must have a business address in Western Australia. And whatever financial, integrity, technical and safety standards are settled on must be continuously met, along with a demonstrated capacity to deliver. Participating businesses will be subject to compliance audit testing.

One of the concerns about such generous incentives is it can jack up the prices of solar gear. Under this program, previous pricing is to be published before each round of rebates for full disclosure; but the finer details of how that will work is also yet to be developed.

The WA Residential Battery Scheme is expected to benefit up to 19,000 Synergy and up to 1,000 Horizon customers. Installers will no doubt be very busy when it kicks in, but between now and then it could be slim pickings for them –  an issue that has already been raised with the Cook Government.

If you’re considering adding solar power and/or battery storage to your home in Western Australia, should you hold off? What if you’re in another state and waiting to see what Labor and the Coalition may offer as federal election sweeteners? And on a related note, might there be an opportunity for WA households to double-dip?
