It offers rebates of up to $5,000 for Synergy customers and up to $7,500 for Horizon Power customers — based on the size of the battery.

What Is the WA Residential Battery Rebate Scheme (2025)?
Launching by 1 July 2025, this scheme provides:
- Rebates of up to $5,000 for Synergy customers
- Rebates of up to $7,500 for Horizon Power customers
- No-interest loans up to $10,000 for eligible households
- Support for new, additional, or replacement battery installations
Battery Rebate Amounts
Synergy Customers (Metro and Southwest WA)
- $500 per kilowatt hour (kWh)
- Up to 10kWh battery capacity
- Maximum rebate: $5,000
- Limited to 19,000 customers
Horizon Power Customers (Regional WA)
- $750 per kilowatt hour (kWh)
- Up to 10kWh battery capacity
- Maximum rebate: $7,500
- Limited to 1,000 customers
Interest-Free Loans
- Loan amounts: $2,000 to $10,000
- Eligibility: Means-tested based on household income (criteria to be announced)
- Repayment period: Up to 10 years (interest-free)
- What can be funded:
- Battery-only systems
- Solar + battery packages
- New or replacement solar panels (only when bundled with a battery system)
In addition to the upfront rebates, the WA Government will also offer interest-free loans of up to $10,000 to help more households afford battery systems — especially those without the upfront capital.
These loans are designed for lower and middle-income households, with income eligibility thresholds to be confirmed closer to the scheme’s launch.
To qualify, systems must meet minimum technical requirements — including a minimum solar system size (yet to be defined) and battery systems of at least 5kWh that are Virtual Power Plant (VPP) ready.
Means-tested benefits are based on your income and assets — only households below certain income thresholds will qualify. In contrast, the rebate portion of the scheme is not means-tested, so it’s available to all eligible households regardless of income.
Eligibility Criteria
Who Can Apply?
- Residential properties in WA with Synergy or Horizon Power accounts
- Home businesses are eligible
Who Is Not Eligible?
- Financial institutions, telcos, and mining/resource companies

Special Consideration for Landlords

Eligible Battery Systems
- New, additional, or replacement battery systems
- Minimum 5kWh storage capacity

Retailer and Installer Requirements
- Must be based in WA
- Required to meet safety, compliance, and technical standards

To protect consumers from price inflation during rebate periods, retailers will be required to publish historical pricing before each new rebate round. This is designed to ensure transparency and fair market pricing
How and When the Scheme Will Roll Out
The scheme will be delivered in multiple rounds starting by 1 July 2025. A third-party administrator with experience in similar programs will manage applications, compliance, and fund disbursement.

Why are the rebates different for Synergy and Horizon Power customers?
The difference reflects the unique energy challenges and higher infrastructure costs in regional and remote parts of Western Australia.
- Synergy supplies electricity to the South West Interconnected System (SWIS), which covers Perth and the southwest. This is a more centralized and stable grid, where energy costs and delivery are relatively efficient.
- Horizon Power serves regional and remote communities, often in off-grid or microgrid settings. These areas face higher energy supply costs, less grid stability, and more frequent outages — making home batteries significantly more valuable for local reliability and energy independence.
To help address these challenges, the WA Government is offering a higher rebate rate — $750 per kWh — for Horizon Power customers, compared to $500 per kWh for Synergy customers.
