Important information for you to know.
Applicant Eligibility Criteria (on this page).
Your approved vendor will apply for the rebate on your behalf; you do not apply directly to the government for your rebate. Plenti, the scheme administrators, has made the list of approved vendors available on their website.
The WA scheme is complementary to the Federal Government’s program it is not limiting the funding available from the Federal Government's program. 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. If the battery was larger than 10kwh, the federal rebate would continue to be applied, so a 15kWh or 30kWh battery would receive over $5,000 in total combined rebate.
The above example assumes a synergy account and that the battery and retailer/installer are on the approved lists
Households will be required to participate in a Virtual Power Plant (VPP) to be eligible for the scheme.
Batteries installed before 1 July 2025 are NOT eligible for the rebate or loan funding.

Virtual Power Plant (VPP) information for customers
Households will be required to participate in a Virtual Power Plant (VPP) to be eligible for the scheme.
A VPP links together thousands of household batteries, creating one large, flexible power source.
During high demand, network managers can draw small amounts of stored energy from participating homes to support the grid during peak demand events.
Batteries installed through the Scheme will help play a vital role in securing WA’s energy future, with households to be financially rewarded when they share their stored renewable power as part of a VPP.
Through VPPs, households will be able to sell energy stored in their battery back to the market – this will help to decarbonise WA and bolster energy security, while offering financial benefits to participating households.
What are the benefits of the WA Residential battery Scheme and joining a VPP?
Upfront savings
The $1,300 WA Battery Rebate reduces the cost of installing a battery, helping you capture your solar energy and lower your electricity bills. When combined with Federal support, the total battery rebate can be close to $19,000.
Extra savings with VPP Credits
Your stored energy is valuable to the energy system, and you should be rewarded for sharing. For example, during a Synergy Battery Rewards activation event, you could earn 70 cents for every unit of electricity you export.
Improve grid reliability
By joining the VPP, your battery helps stabilise the WA Electricity Grid, reducing the risk of blackouts, and reducing infrastructure maintenance & upgrade costs. Long-term, this helps to minimise electricity price inflation, helping those in the community who aren’t able to invest in a Solar & Battery system.
Flexibility after two years
The VPP agreement is only two years, after which you can opt out at any time. This provides flexibility while still unlocking rebates and credits.
Interest-free loans
Eligible participants can access loans of up to $10,000, with no interest and flexible repayment terms of 3–10 years.
VPP myths
- “You lose control of your battery” – Not true. For instance, Synergy’s VPP only accesses your battery up to 30 times per year, for a maximum of 6 hours per event — less than 2% of the year.
- “It shortens battery life” - Grid support discharges energy from your battery in the same way as powering your home, with little to no impact on lifespan.
- “The credits don’t stack up” – Even after buying back energy at standard energy rates, VPP participants still achieve greater overall savings than if they had kept the battery for household use only.
Virtual Power Plant requirements for rebate and loans
With the scheme now extended to support an estimated 100,000 batteries, it may contribute around 1GWh of storage to the grid. For home batteries to reliably deliver benefits to the system they need to work together. This can only be achieved through VPPs, and this is how households receiving the rebate will help secure our clean energy future.
All customers will be able to subscribe to the VPP product offered by their electricity retailer (Synergy or Horizon Power).
Both retailer products are designed to share value with the customer
These products have been designed to ensure they reflect the benefit shared with the community and that they are fair and reasonable.
As VPPs evolve and mature, VPP products will also evolve and mature.
Synergy customers will be able to choose an alternative VPP product, as long as it meets the following criteria:
the alternative product is offered by the supplier of the customer’s battery and is compatible with the customer’s equipment;
the alternative product is designed to share the value of the batteries working together with the customer; and
the alternative product is backed by genuine value streams.
Further information on eligible VPP products is available from their providers, links listed below.
