If you’re a WA homeowner thinking about installing a home battery, there’s never been a better time. Starting July 2025, the WA Government is launching a powerful new rebate for batteries — designed to slash upfront costs and help households take control of their energy bills. Here’s what you need to know, including rebate amounts, eligibility, and how to apply.
How Much Is the Battery Rebate in WA?
The WA Government is offering a generous battery rebate starting from 1 July 2025. The rebate amount is based on the usable capacity of your battery, but only up to a maximum of 10 kWh — anything above that won’t receive additional support. The rebate depends on which electricity provider you’re with and the size of the battery you install:
- Synergy customers can receive $130 per kilowatt-hour (kWh) of usable battery capacity, up to a maximum of $1,300.
- Horizon Power customers receive a much higher rate of $380 per kWh, with a cap of $3,800.
This means if you install a 10 kWh battery, you could get either $1,300 or $3,800 off the cost depending on your provider. And if you combine this with the Federal battery rebate, your total savings for 10kWh battery could exceed $7,500 — making it one of the best times to invest in battery storage.
| Customer Type | WA Rebate per kWh | WA Max Rebate | Federal Rebate (10 kWh) | Total Potential Rebate |
|---|---|---|---|---|
| Synergy Customers | $130/kWh | $1,300 | $3,720 | $5,020 |
| Horizon Power Customers | $380/kWh | $3,800 | $3,720 | $7,520 |

| 10 kWh | $1,300 (max) | $3,800 (max) | $3,720 | $5,020 | $7,520 |

Who’s Eligible for the WA Battery Rebate?
To qualify, you must meet these conditions:
- Live in WA and have your main residence on the property.
- Be a Synergy or Horizon Power customer.
- Not be a government or commercial property owner (banks, telcos, mining).
- Your battery must be connected to rooftop solar.
- Your system must be VPP-ready (able to connect and respond to energy signals).
- Must have ongoing internet connection for remote battery monitoring.
Good news — rental properties are eligible too (with landlord approval), and home-based businesses can apply if the home is also the main residence.
What Kind of Batteries Are Eligible?
To be eligible, your battery must meet these specs:
- New, additional, or replacement system
- Minimum of 5 kWh usable capacity
- Must be on the CEC-approved product list
- Installed by a SAA-accredited installer
- Comply with Synergy or Horizon Power technical standards
Battery systems must also be VPP-capable and tested for reliable communication and integration with the grid.
Tip: Final lists of eligible battery systems will be published closer to launch (expected mid-2025). We’ll update this blog when that’s available.
What About Loans?
The WA Government will also offer interest-free loans of up to $10,000, available for:
- Battery systems
- Upgraded inverters
- New solar panels (if bundled with battery)
Loan details:
- Up to 10-year terms
- Household income must be under $210,000
- Subject to a basic credit check
- No fees for customers in good standing
How to Apply for the Rebate
The official application portal will go live closer to July 2025, but here’s what you can prepare:
- Confirm you are a Synergy or Horizon Power customer.
- Choose a CEC-listed, VPP-ready battery system.
- Get installation quotes from SAA-accredited installers.
- Ensure your home has reliable internet for battery monitoring.
