Quick Answer
You may qualify when you live in Western Australia and you own your home. In the questionnaire it is reached with state = WA and is_homeowner = true.
It combines a rebate and an interest-free loan. Synergy customers can get a rebate of up to $1,300 and Horizon Power customers up to $3,800, with an interest-free loan available on top. The exact rebate depends on your battery capacity and network, so our model treats it as eligibility_only rather than computing a single number.
Outcome summary: lower upfront cost for a home battery, plus the ongoing benefit of storing your solar - on the condition that the battery joins a Virtual Power Plant (VPP).
What Is This Payment?
The Residential Battery Scheme is a clean-energy program run by Energy Policy WA. It cuts the upfront cost of installing a home battery through a rebate, and spreads the rest with an interest-free loan, so more households can store the solar they generate.
In the rule database this is a Group B benefit with eligibility_only as its result role. Because the rebate varies by battery capacity and by network (Synergy versus Horizon Power), our model does not compute a single dollar figure; it confirms your eligibility and describes the rebate range.
A condition of the scheme is that the battery joins a Virtual Power Plant (VPP) - a coordinated network of home batteries that can be drawn on to support the grid, which is part of why the support is offered.
How Much Can You Get?
The amount block is eligibility_only, so our model does not compute a single figure. The value is a rebate plus an interest-free loan, with the rebate varying by battery capacity and network.
- Synergy customers: a rebate of up to $1,300.
- Horizon Power customers: a rebate of up to $3,800.
- Interest-free loan available on top of the rebate to cover the remaining cost.
- VPP condition: the battery must join a Virtual Power Plant to qualify.
Your actual rebate depends on your battery's capacity and your network, so confirm the figure on the official Energy Policy WA page.
Eligibility Conditions
The eligibility block is an all set, so every condition below must be true.
- Western Australian resident:
state = WA. The scheme is for WA households. - You own your home:
is_homeowner = true. The scheme supports homeowners installing a battery at their property.
Beyond residency and home ownership, the scheme requires the installed battery to join a Virtual Power Plant, and the rebate amount depends on whether you are a Synergy or Horizon Power customer and on the battery's capacity.
Because the rebate and loan are tied to a specific battery and network, confirm the current offer, eligible products and any caps on the official Energy Policy WA page before you commit to an installation.
How To Apply
The channel is online through Energy Policy WA, and you will need proof of home ownership.
- Apply online via the Energy Policy WA Residential Battery Scheme page.
- Provide proof that you own the home where the battery will be installed.
- Choose an eligible battery that can join a Virtual Power Plant.
- Confirm whether you are a Synergy or Horizon Power customer to see your rebate range.
Rule-Based Scenarios
Scenario 1: a Synergy household in the metro area
Emma owns her home in Perth and is a Synergy customer with rooftop solar. She installs an eligible battery, joins a Virtual Power Plant and claims a rebate of up to $1,300, with an interest-free loan covering the rest.
Scenario 2: a Horizon Power household in the regions
Tom owns his home in Broome and is a Horizon Power customer. Because regional networks attract a larger rebate, he can claim up to $3,800 towards his battery.
Scenario 3: spreading the cost
Priya in Albany owns her home but cannot pay the full battery cost upfront. She takes the rebate and an interest-free loan, repaying the balance over time rather than all at once.
Scenario 4: a renter misses out
Jack rents his unit in Fremantle and would like a battery, but the scheme is for homeowners. As he does not own the property, he does not meet the is_homeowner = true condition.
Common Mistakes
- Skipping the VPP condition: the battery must join a Virtual Power Plant - a battery installed outside the scheme's VPP requirement will not attract the support.
- Assuming everyone gets the same rebate: the rebate varies by network - up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers - and by battery capacity.
- Forgetting the interest-free loan: the rebate is only part of the support; an interest-free loan is available on top to help cover the remaining cost.
- Applying as a renter: the scheme is for homeowners. You must meet the home-ownership condition at the property where the battery is installed.
- Expecting our model to quote one number: it is eligibility_only because the rebate depends on your battery and network - confirm your figure on the official page.
- Buying a battery before checking eligibility: confirm the eligible products, your network rebate and the VPP requirement on the Energy Policy WA page before committing to an installation.
