What Is the WA Home Battery Rebate?
The Western Australian Government has introduced the Residential Battery Scheme to encourage more households to install home battery storage systems. The program aims to make battery technology more affordable while improving the reliability of the state’s electricity network.
A home battery stores excess electricity generated by your solar panels during the day, allowing you to use that stored energy at night or during periods of high electricity prices. This helps reduce reliance on the grid and lowers ongoing energy costs.
The scheme provides eligible households with an upfront rebate that is applied at the time of installation through an approved installer or vendor. Depending on your electricity network, the rebate amount varies.
WA Battery Rebate Amounts
The rebate is calculated based on the usable capacity of your battery, with incentives available for up to the first 10kWh.
| Electricity Provider | Rebate Rate | Maximum Rebate |
| Synergy Customers | $130 per usable kWh | Up to $1,300 |
| Horizon Power Customers | $380 per usable kWh | Up to $3,800 |
The rebate is available for one eligible battery system per residential property and is applied as an upfront discount rather than a reimbursement.
Although you can install a battery larger than 10kWh, the rebate applies only to the first 10kWh of usable storage capacity.
Interest-Free Loans Available
Alongside the rebate, the WA Government is also offering interest-free loans to help eligible households spread the cost of purchasing a battery system.
Loan features include:
- Borrow between $2,001 and $10,000
- Repayment terms ranging from 3 to 10 years
- Zero interest charges
- Available to households with an annual income below $210,000 (subject to eligibility and credit assessment)
The loan may be used to cover:
- Solar battery systems
- Hybrid inverters
- Solar panels when installed as part of a battery package
This additional financial support makes it easier for homeowners to invest in long-term energy savings without paying the full installation cost upfront.
Who Can Apply?
To qualify for the WA Home Battery Rebate, applicants generally need to meet several eligibility requirements.
You may be eligible if you:
- Are at least 18 years of age.
- Are an Australian permanent resident.
- Live in Western Australia.
- Receive electricity through Synergy or Horizon Power.
- Install a new or replacement battery with at least 5kWh usable capacity.
- Use an approved installer and eligible battery system.
- Connect the battery to an approved Virtual Power Plant (VPP) for the required participation period.
Only one rebate is available for each eligible residential property.
Landlords, renters with permission from the property owner, and some home-based businesses may also qualify, provided they meet the scheme requirements.
Why This Rebate Matters
Battery storage has become one of the most effective ways for homeowners to maximise the value of their solar system. Instead of exporting excess solar energy during the day, a battery allows you to store that electricity and use it when your household needs it most.
With generous government incentives now available, the cost of installing a battery has become significantly more affordable for many Western Australian households.
As battery technology continues to improve, more homeowners are choosing storage solutions to reduce electricity bills, increase energy independence, and better prepare for future energy price increases.
At Solar Authority, we recommend comparing battery sizes, warranties, compatibility, and installation quality—not just the purchase price—to ensure you receive the best long-term value from your investment.
Can You Combine the WA Home Battery Rebate with the Federal Battery Rebate?
Yes. One of the biggest advantages of the WA Home Battery Rebate is that it can generally be combined with the Australian Government’s battery incentive, provided you meet the eligibility requirements for both programs.
By stacking both incentives, eligible households can significantly reduce the overall cost of installing a home battery system. This makes battery storage a more attractive investment for homeowners who already have solar panels or are planning to install a complete solar and battery package.
The exact amount you save depends on several factors, including:
- Your electricity provider (Synergy or Horizon Power)
- The usable capacity of your battery
- The federal incentive available at the time of installation
- The approved battery and installer you choose
Estimated Combined Savings
| Customer Type | WA Rebate | Estimated Federal Incentive* | Potential Total Savings |
|---|---|---|---|
| Synergy Customer | Up to $1,300 | Around $2,500 | Around $3,800 |
| Horizon Power Customer | Up to $3,800 | Around $2,500 | Around $6,300 |
*Federal incentive values are indicative only and may change based on government program settings and market conditions.
For many homeowners, combining both rebates can reduce the upfront cost of battery installation by thousands of dollars.
Virtual Power Plant (VPP) Requirements
To receive the WA Home Battery Rebate, eligible battery systems must be connected to an approved Virtual Power Plant (VPP).
A Virtual Power Plant is a network of connected home batteries that work together to support Western Australia’s electricity grid. During periods of high demand or network stress, participating batteries can help balance electricity supply while homeowners continue to benefit from battery ownership.
In most cases, your installer will complete the VPP setup during installation.
Typical VPP Requirements
- Battery must have internet connectivity.
- Battery must support remote communication.
- The system must be compatible with an approved VPP provider.
- Participation is generally required for a minimum of two years.
After the required participation period, homeowners may have the option to leave the VPP without affecting the rebate already received, depending on the scheme rules.
How to Apply for the WA Battery Rebate
Applying for the rebate is straightforward because homeowners do not usually submit the application themselves.
Instead, your approved battery installer or authorised vendor manages the application process on your behalf.
Step 1 – Check Your Eligibility
Confirm that you meet the scheme requirements, including your electricity retailer, battery size, and property eligibility.
Step 2 – Compare Battery Systems
Request quotes from reputable battery installers and compare battery capacity, warranty, performance, and compatibility with approved VPP programs.
Step 3 – Select an Approved Installer
Choose an installer who supplies eligible battery products and participates in the WA rebate program.
Step 4 – Application Submission
Your installer submits the rebate application and, if required, assists with the interest-free loan application.
Step 5 – Installation
Once approved, your battery system is installed, connected to your home’s electrical system, and enrolled in an approved Virtual Power Plant.
Step 6 – Receive Your Discount
The rebate is generally applied as an upfront discount, reducing the amount you pay for the installation.
Example Battery Costs After Rebates
Although battery prices vary depending on brand, capacity, and installation complexity, government incentives can substantially reduce the upfront investment.
| Example | Estimated Amount |
| Battery System Price | $12,000 |
| WA Rebate (Horizon Power) | -$3,800 |
| Estimated Federal Incentive | -$2,500 |
| Remaining Cost | Approximately $5,700 |
Eligible households may also finance part or all of the remaining balance using the available interest-free loan, subject to approval.
Choosing the Right Home Battery
Government rebates are only one part of the decision. Selecting a high-quality battery system can deliver better long-term savings, improved reliability, and greater peace of mind.
When comparing battery options, consider:
Battery Capacity
Choose a battery that suits your household’s electricity usage. A larger battery isn’t always the best option if your daily energy consumption is relatively low.
Warranty
Look for manufacturers offering at least a 10-year product warranty with strong performance guarantees.
Battery Efficiency
Higher round-trip efficiency means more of your stored solar energy can be used in your home.
VPP Compatibility
Ensure the battery supports approved Virtual Power Plant programs required under the WA rebate scheme.
Brand Reputation
Choose products from trusted manufacturers with proven reliability, local support, and a strong installation network across Australia.
At Solar Authority, we recommend comparing more than just the purchase price. Factors such as warranty coverage, battery lifespan, installer experience, and after-sales support can have a significant impact on your long-term return on investment.
