WA Residential Battery Rebate and Loan Scheme (From 1 July 2025)
Starting by 1 July 2025, the WA Government will launch a $387 million Residential Battery Scheme to support battery adoption across the state.
| Customer Type | Rebate Per kWh | Max kWh | Max Rebate | Cap |
|---|---|---|---|---|
| Synergy Customers (Metro & SW WA) | $500/kWh | 10 | $5,000 | 19,000 households |
| Horizon Power Customers (Regional WA) | $750/kWh | 10 | $7,500 | 1,000 households |
For lower and middle-income households, interest-free loans up to $10,000 will also be available to help cover the cost of:
- Battery-only systems
- Solar + battery packages
- Repayable over 10 years
Battery systems must be at least 5kWh and Virtual Power Plant (VPP) ready. Applications open in mid-2025, with rollouts in several phases.
See more in this step-by-step guide to the WA Residential Battery Rebate Scheme (2025 Step-By-Step Guide).
Federal Solar Rebate: Small-scale Renewable Energy Scheme (SRES)
The SRES is the main financial incentive for WA residents installing solar systems. Here’s how it works:
- How it works: Each eligible solar system earns Small-scale Technology Certificates (STCs) based on system size and location.
- Claiming STCs: Installers usually deduct the rebate upfront.
- Rebate value: In 2025, a standard 6.6kW system in Perth receives around $2,200–$2,600 off upfront.
- Phase-out: The SRES reduces each year until it ends in 2030..
See more on how to calculate and access STCs in WA see our comprehensive guide to STCs.
Distributed Energy Buyback Scheme (DEBS)
DEBS also allows eligible households, schools, and non-profits to receive payments for surplus electricity exported to the grid. This includes energy generated by:
- Rooftop solar photovoltaic (PV) systems.
- Home battery storage systems.
- Electric vehicles (EVs) capable of exporting power.
Unlike older buyback programs, DEBS emphasizes the time of export, offering higher rates during peak demand periods. This structure incentivizes energy generation and export when it’s most valuable to the grid.
How Does DEBS Work?
Under DEBS, payments vary depending on the time of day:
| Time of Day | Example Rate |
|---|---|
| Peak (3 pm – 9 pm) | 10 cents/kWh |
| Off-Peak (9 pm – 3 pm) | 2 cents/kWh |
- Peak Periods: Higher rates are offered between 3 pm and 9 pm, reflecting increased demand and wholesale electricity costs.
- Off-Peak Periods: Lower rates apply during periods of abundant solar energy generation, encouraging households to self-consume or store energy
How to apply:
Applications must be submitted through your energy retailer (e.g., Synergy or Horizon Power). Installers typically handle this during system setup or upgrades.
