Are those soaring power bills keeping you up at night? Imagine cutting those costs by storing solar energy for when you need it most and getting paid for sharing excess power.
WA Residential Battery Scheme can make that happen, but only if you know what to ask, who to trust, and how to apply. The details can feel overwhelming.
Don’t worry. This easy and detailed guide will walk you through everything. We’ll explore what you’ll get and save, who’s eligible, how the WA battery rebate stacks with federal support, what joining a WA VPP really means, and the exact steps to claim your rebate.
Read on… in 5–10 minutes you’ll know exactly how to claim your WA battery rebate and avoid costly mistakes.
What is a Residential Battery?
A residential battery is simply a home energy storage unit. It stores excess electricity from your solar panels or cheap off-peak grid power and lets you use it later.
For example, you can charge the battery with rooftop solar during the day and draw from it in the evening. This saves you money by avoiding higher night-time rates. Solar batteries can even keep the lights on during a blackout and help you go off-grid.
In short, a home battery boosts your energy independence and cuts bills by storing renewable power for when you need it.
What is the WA Residential Battery Scheme (2025)? Battery Rebates & Loans Explained
Starting 1 July 2025, the WA State Government is offering big incentives to help homeowners install batteries. The scheme provides generous state rebates and interest-free loans, on top of the Federal Government’s Cheaper Home Batteries program.
WA Battery Rebates:
The WA scheme pays $130 per kWh of usable battery for Synergy customers, and $380 per kWh for Horizon Power customers. This means up to $1,300 for a 10 kWh battery (Synergy) or $3,800 (Horizon).
Batteries larger than 10 kWh still get the same maximum rebate (e.g. a 15 kWh battery gets $1,300 or $3,800, not more).
When you add the federal rebate, this adds roughly $372 per kWh of usable capacity in 2025 (so about $3,720 on 10 kWh):
- Synergy households can save roughly $5,000.
- Horizon households can get about $7,500.
After program fees, owners typically see about $3,300 net value on that 10 kWh example. The great news: you can combine the WA and federal rebates. Both Synergy and Horizon customers can apply for both schemes.
Interest-Free Loan:
In addition to rebates, low/middle-income homes can borrow up to $10,000 at 0% interest. The loan can cover batteries and related gear like a new inverter or extra solar panels if installed with the battery.
Eligibility for the loan requires a gross household income under $210k; verified by recent tax returns.
Are You Eligible for the WA Battery Scheme?
To get the WA battery rebate and loan, you must meet several criteria. Here’s an eligibility checklist for homeowners:
- Who can apply: You must be an Australian permanent resident, 18+, and a customer of Synergy or Horizon Power.
- Property: The home must be in Western Australia. It can be a standalone house or a unit-title property (with owners’ corp. approval). The property should be predominantly residential.
- Ownership: You can be the homeowner or the landlord. Rental homes are eligible if you have your landlord’s written consent to install the battery.
- Internet: Your home must have an ongoing internet connection (required for VPP control).
- Battery specs: The battery must be new or an add-on, not a used unit. It needs at least 0 kWh usable capacity. That’s roughly a 10 kWh nominal battery, depending on model.
- Approved products: The battery model must be on the Clean Energy Council’s approved list and on the Synergy/Horizon approved solutions list. In other words, only officially-certified batteries are covered.
- VPP: Crucially, you must sign up to a VPP product offered by your retailer (more on VPPs below).
Not eligible: Government-owned buildings, banks, telcos or mining facilities don’t qualify. Also, batteries installed before 1 July 2025 are not eligible.
If all that checks out, you’re good to go. For loan eligibility, remember your household income must be ≤ $210,000 (combined).
What is a Virtual Power Plant (VPP) & What Joining VPP Means for Your Battery
A Virtual Power Plant (VPP) is a network that links home batteries together. When your battery has spare energy, it can feed it back to the grid to help during peak demand. In return, you get rewarded (usually via bill credits).
Why WA requires VPP participation:
In WA’s scheme, joining a VPP is mandatory. Essentially, your battery becomes part of a larger system that balances the grid.
The State needs battery owners to share stored energy at the right times to stabilise supply and cut carbon emissions. By aggregating thousands of home batteries, the grid gets extra power during spikes (like hot afternoons) and stores it otherwise. Thus, joining a VPP means you sign a contract with your retailer (Synergy or Horizon) for their VPP program.
Benefits of joining a VPP:
- Earn rewards: You’ll be financially rewarded for exporting energy when the grid needs it most.
- Support the grid: Your battery helps avoid blackouts and higher emissions by sharing stored energy. This benefits the community and the environment, and big energy companies return value to participants in fair programs.
- No extra cost: There’s usually no fee for joining a retailer’s VPP product. You simply allow your battery to be used when needed.
How to Apply for WA Battery Rebate: Step-by-Step Process
Applying can seem daunting, but the steps are straightforward. Here’s a clear sequence:
- Check eligibility: Use the checklist above and government resources or contact us to confirm you qualify.
- Get quotes from accredited vendors: Only installers accredited under the WA scheme can submit applications. Ask each installer for an itemised quote that shows: the battery/inverter models, total cost, and how much the rebate will knock off the price. Ensure they offer SAA (Solar Accreditation Australia) GCBS accreditation for installing batteries.
- Verify approved products: Make sure your chosen battery and inverter are on the Clean Energy Council’s approved battery list and the Synergy/Horizon supported solutions list. If in doubt, request proof in writing.
- Select your vendor and equipment: Choose the installer and battery that fit your needs and budget.
- Installer submits your application: You do not apply directly. Your approved vendor will apply to the WA scheme on your behalf. They’ll bundle your rebate (and loan, if requested) with the state’s system.
- Loan application (if needed). If you choose to take the interest-free loan, the scheme administrator will contact you after the installer applies. You’ll need to provide your tax documents (FY23–24 return, etc.) for income verification.
- Installation & inspection. Once approved, schedule the installation with your installer. The scheme requires a post-install inspection to confirm everything meets standards. The government allows 6 months from approval to complete installation, so plan promptly.
- Receive rebate/loan. After final paperwork and inspection, the installer will claim the rebate and loan funds. The rebate will typically be paid to the installer, who’ll credit it
How to Choose a Solar Battery Installer
A good installer is just as important as a good battery. Follow these steps:
-
Verify credentials:
Ensure the company has an Australian business address and ABN (required by law). For the WA scheme, installers must hold a Grid-Connected Battery System (GCBS) accreditation from SSA (Solar Accreditation Australia).
-
Check reviews and experience:
Look for local reviews, years in business, and examples of past installations. A trustworthy installer will readily share references and case studies.
-
Read the contract carefully:
You should get a detailed written quote before paying. It must list all equipment (battery & inverter models), a breakdown of costs and rebates, payment schedule, installation timeline, warranty terms, and cancellation policy.
Check that rebates are clearly separated so you know what you actually owe.
-
Use secure payment:
Don’t pay large deposits in cash or by direct bank transfer. It’s safer to use a credit card or PayPal, which allow dispute resolution.
Scams & Consumer Protection: How to Spot Frauds & Red Flags
Since big rebates attract scammers, stay vigilant. Here are common tricks and how to protect yourself:
- Unverifiable ID: The company won’t provide a local address or changes names frequently.
- “Register now” pressure: Aggressive calls or ads saying ‘don’t miss out the deadline!’ or ‘register now’ can be the scammers that create false sense of urgency.
- Requests for personal data: Legit battery installers won’t ask for IDs, bank details, or to sign contracts without a quote first.
- Free giveaways: No installer will give you a completely free battery. They offset it with higher charges. If someone promises a ‘free battery installation,’ treat it as a red flag.
- No written quote: Only a verbal deal or a quote that omits equipment specs and pricing.
- Offshore entities: Installer claims to have a foreign head office or only a mobile number.
- Deposits for no reason: Never pay cash or bank transfer to “reserve your rebate.” Installers should present a no-obligation quote and only ask for payment for the actual battery cost and work. A secure credit card is safer.
- Misused logos: Using the WA Government logo on ads or forms without permission (this is illegal).
- No mention of VPP: If the installer talks up the rebate but never mentions the VPP requirement, be cautious.
If you spot any of these signs, it’s best to step back. Always ask for proof in writing: ABN, licenses, a detailed quote, warranty documents, and official product datasheets.
If something feels off, trust your gut and consider reporting the firm to Consumer Protection WA

FAQs About WA Residential Battery Scheme
1. What is the WA residential battery scheme?
It’s a new state program that offers battery rebates and loans for WA homeowners. Eligible households can get up to $1,300 (Synergy) or $3,800 (Horizon) off a 10 kWh battery, plus an interest-free loan up to $10,000. It’s meant to complement the federal Cheaper Home Batteries rebate, effectively lowering your battery cost.
2. What is the minimum battery size for the WA Residential Battery Scheme?
Your battery must have at least 5.0 kWh usable capacity to qualify for WA battery rebate. This means a 10 kWh nominal battery.
3. Can I combine the WA rebate with the federal Cheaper Home Batteries program?
Yes. The WA scheme is explicitly designed to combine with the federal rebate. As a result, you can get both incentives on one battery. For example, a Synergy customer can get $1,300 from WA plus about $3,720 from the federal scheme for a 10 kWh battery.
4. Do I have to join a VPP to receive the battery rebate?
Yes, participation in a Virtual Power Plant is required to get the rebate or loan in WA. This means you agree to link your battery to an approved VPP product (Synergy’s or Horizon’s VPP plan).
5. How long does the application and rebate process take?
There are a few steps: quoting, approval, installation, and inspection. The official rules give you up to 6 months to complete installation after approval.
6. Are renters eligible for the WA battery scheme?
Yes, if you have landlord permission. The applicant must either own the home or have the landlord’s written consent to install the battery. You’ll need to provide that consent form with the application.
7. What happens if I move house after battery installation?
The WA rebate assumes the battery stays with the property. The rules require the battery to be installed for permanent use at that address. If you sell or move, you generally leave the battery behind. You can’t claim the rebates again on a new home, so you’d need a fresh application in the new location.
