Western Australia has introduced one of the most supportive state-level solar battery rebate programs in Australia — the WA Residential Battery Scheme — making home energy storage significantly more affordable when paired with rooftop solar. This initiative is designed to reduce electricity bills, improve grid resilience and accelerate the transition to cleaner energy in WA.
🔋 What Is the WA Residential Battery Scheme?
The WA Residential Battery Scheme is a state government program offering upfront rebates and no-interest loans to eligible Western Australian households that want to install a solar battery at their home. It runs alongside the federal Cheaper Home Batteries Program, allowing eligible homes to stack state and federal rebates for even greater savings.
Under the scheme, rebates are available based on battery capacity and whether you’re a customer of either of WA’s main energy retailers: Synergy or Horizon Power.
💰 How Much Can You Save?
🔸 Rebate Amounts
The rebate is calculated on a per usable kWh basis — up to a 10 kWh cap:
- Synergy customers: up to $1,300 total rebate ($130 per usable kWh × 10 kWh)
- Horizon Power customers: up to $3,800 total rebate ($380 per usable kWh × 10 kWh)
These rebates are in addition to the federal Cheaper Home Batteries Program — meaning a typical 10 kWh system could receive combined discounts of up to ~$5,000 for Synergy customers or up to ~$7,500 for Horizon Power customers when both state and federal support are applied.
📍 Who Is Eligible?
To qualify for the WA Residential Battery Scheme rebate:
1. Resident Criteria
✔ You must be an Australian resident aged 18+
✔ You must be a customer of Synergy or Horizon Power
✔ You must be installing the battery on a residential property in WA
2. Approved Products & Installation
✔ Battery systems must appear on the Clean Energy Council’s approved product list
✔ Batteries must comply with retailer and network technical requirements
✔ Installation must be done by an accredited installer, typically arranged through approved vendors
✔ You must sign up for a Virtual Power Plant (VPP) product offered by your retailer to qualify for the rebate
Participation in a VPP helps coordinate stored energy across the grid, offering financial value back to households and supporting broader network stability.
3. Property Conditions
✔ Must be a primary residence or a rented property with landlord consent
✔ Must have permanent internet connection for system testing and VPP operations
💡 No-Interest Loans Are Available Too
In addition to rebates, eligible households earning under $210,000 per year may qualify for a no-interest loan of up to $10,000 to help cover the costs of batteries, inverters or upgrades that accompany a battery installation.
- Loan terms range from 3 to 10 years
- There are no interest charges or early repayment fees (aside from small late fees if payments are missed)
- Loan + rebate combined cannot exceed the full purchase and installation cost
🔌 Virtual Power Plant (VPP) Requirement
Under the WA scheme you must join a retailer’s VPP (or an approved alternative product) to be eligible for the rebate. These VPPs:
- Allow your stored solar energy to be used during peak demand periods
- Provide financial credits or rewards in return
- Help stabilise the grid by coordinating supply and demand from distributed energy resources
Participation is usually for a minimum of two years, after which you can opt out if you choose.
📆 Scheme Status & Timing
- The WA Residential Battery Scheme officially opened on 1 July 2025 and is currently available.
- Rebates are limited to the first 100,000 eligible participating households, so acting sooner increases your chances of securing support.
📈 How the Scheme Benefits Homeowners
Lower Upfront Costs
Combining state rebate support with the federal Cheaper Home Batteries discount significantly cuts the cost of installing a battery — making systems far more affordable.
Ongoing Financial Benefits
By participating in a VPP and using a solar battery:
✔ You can reduce your grid electricity consumption
✔ You may receive additional bill credits through VPP rewards
✔ You increase your solar self-consumption and energy independence
Support for Clean Energy Transition
State and federal incentives aim to encourage rooftop solar + battery adoption. Stored energy from home systems can be aggregated through VPPs to help balance the grid and reduce peak demand stress.
⚠️ Important Things to Know
✔ Batteries installed before 1 July 2025 are not eligible for the WA rebate.
✔ Only one rebate is available per property (even if you add or replace batteries later).
✔ Some installers and applicants experienced administration delays or technical issues with approvals — working with experienced installers and confirming vendor eligibility can help streamline the process.
