Western Australian homeowners now have a critical window to claim significant savings on home battery systems, with combined state and federal rebates potentially reaching up to AUD $7,500. The WA Residential Battery Scheme is officially open and was last updated on 29 June 2026, offering substantial incentives that stack with the existing Federal Government’s Cheaper Home Batteries Program. However, the federal component is set to reduce from 1 January 2027, creating an urgent incentive for households to act now.
The WA Residential Battery Scheme aims to accelerate the adoption of battery storage, allowing residents to maximise their rooftop solar investments, reduce reliance on grid electricity, and contribute to the state’s clean energy transition. This initiative is particularly timely as electricity prices remain a concern for many households across the country.
WA Residential Battery Scheme: Key Details
The Western Australian government’s scheme provides direct financial support to households installing new battery storage systems. The rebate amount varies based on the electricity retailer serving the property:
| Customer Type | WA State Rebate Amount |
|---|---|
| Synergy Customers | Up to AUD $1,300 |
| Horizon Power Customers | Up to AUD $3,800 |
For Synergy customers, the rebate is calculated at AUD $130 per usable kWh of battery capacity, capped at AUD $1,300. To be eligible, households must ensure their chosen battery is on the Clean Energy Council approved list and meets Synergy’s technical standards. Crucially, participation in a Virtual Power Plant (VPP) is a mandatory requirement for the WA scheme. Batteries installed before 1 July 2025 are not eligible.
Stacking with the Federal Cheaper Home Batteries Program
The WA Residential Battery Scheme is designed to complement the Federal Government’s ongoing Cheaper Home Batteries Program. This federal initiative provides an upfront discount on eligible battery systems, typically equating to approximately 30% off the upfront cost, or about AUD $344 per usable kWh for the first 50 kWh of battery capacity.
When combined, these two programs offer a powerful incentive. For example, a 10kWh battery system for a Synergy customer could see a combined rebate of around AUD $5,000 (AUD $1,300 from WA plus approximately AUD $3,720 from the federal program). For Horizon Power customers, the total savings can be even more substantial, potentially reaching up to AUD $7,500 depending on the battery size.
“The WA Battery Rebate Scheme is Now Officially Open! Important information for you to know. The WA scheme is complementary to the Federal Government’s program the cheaper Home Batteries Program. For example: A 10kWh battery would be eligible for the maximum $1,300 rebate from the WA Battery Scheme. The rebate would increase to $5,000 when combined with the federal rebate.”
No-Interest Loan for Broader Upgrades
Beyond the direct rebates, eligible Western Australian households can also access a no-interest loan to further reduce the financial barrier to installing clean energy solutions. These loans are available for amounts ranging from AUD $2,001 to AUD $10,000, with repayment terms spanning 3 to 10 years.
This loan can cover the cost of the battery system itself, and when installed alongside it, can also extend to associated equipment like inverters or solar panels. Eligibility for the no-interest loan is set for households with a gross annual income under AUD $210,000. The loan program is administered by Plenti on behalf of the WA Government.

Virtual Power Plants and Future-Proofing
The requirement to participate in a VPP for the WA scheme highlights a growing trend in Australia’s energy market. VPPs allow aggregated home batteries to act as a collective power source, providing grid services and potentially earning participants additional revenue. This integration is crucial for maintaining grid stability as more intermittent renewable energy sources come online.
Installing a home battery not only offers financial benefits through rebates and reduced electricity bills but also enhances energy resilience, providing Home Battery Backup for Blackouts in 2026: Systems & Costs from $7,000. When considering a new solar system or adding a battery, it’s also important to assess your long-term energy needs, especially with the rise of electric vehicles and home electrification.

Act Before 2027
The window for maximising these combined rebates is closing. While the WA Residential Battery Scheme continues, the federal Cheaper Home Batteries Program will see its subsidy levels reduce from 1 January 2027. Households considering a battery installation are encouraged to consult with approved installers to understand their eligibility and secure the highest possible savings before the federal step-down takes effect.
This concerted effort from both state and federal governments provides a compelling financial case for Western Australian households to invest in battery storage now, boosting energy independence and contributing to a cleaner, more resilient energy future.
