Big News for WA Homeowners:
Battery Rebates Are Here
Stackable Government Rebates
Battery Rebates
If you live in Western Australia and have been thinking about adding a home battery, 2025 might be the perfect time. The WA Government has just announced its own Residential Battery Scheme, offering eligible homeowners up to $3,800 in state rebates, plus the ability to stack it with the new federal battery rebate. Combined, some households could access $5,000 to $7,500 in total battery support one of the most generous rebate packages in the country.
Launching July 2025
Scheme Launch
The scheme officially launches on 1 July 2025, and it’s designed to reduce power bills, ease pressure on WA’s electricity grid, and support smarter home energy use through participation in a Virtual Power Plant (VPP).
But like any government program, the details matter and we’ve unpacked them all for you below.
How Much Can You Get?
The total rebate support available in WA depends on who your electricity provider is and whether your system qualifies under both the state and federal battery programs.
Here’s how it breaks down:
| Customer Type 👥 | Combined Rebate (Federal + WA) 💸 |
|---|---|
| Synergy (metro areas) | Up to $5,000 |
| Horizon Power (regional/remote) | Up to $7,500 |
Rebate Eligibility Criteria
These totals represent a combined maximum across the new WA state rebate and the federal government’s battery incentive program. Actual amounts will vary based on your battery size, installer accreditation, and your VPP participation.
To qualify for the rebate, you’ll need:
- A battery sized between 5–50 kWh (usable capacity)
- A participating Virtual Power Plant (VPP) agreement
- An approved installer and compliant product
Bonus Support: Interest-Free Loans Available
WA households earning less than $210,000 per year may also be eligible for an interest-free loan of up to $10,000 to help cover upfront costs. These loans will be available through the WA Government’s Smart Energy platform, and financing will be delivered via Plenti, a government-approved lender. The scheme launches on 1 July 2025, alongside the rebate program.
Federal Rebate + State Rebate = Big Savings
Western Australians can now combine both federal and state battery incentives giving eligible households up to $5,000–$7,500 in total support. Here’s how it works:
Federal Rebate
- Offers $372 per usable kilowatt-hour (kWh)
- Available nationwide for eligible batteries (up to 50 kWh)
- A typical 10–13 kWh battery could receive $3,300–$4,800 from the federal program
WA State Rebate
- Synergy customers (metro/Perth area): up to $1,300
- Horizon Power customers (regional/remote WA): up to $3,800
- Requires participation in an approved Virtual Power Plant (VPP)
What You Could Receive in Total (Example Battery Sizes)
| Location 📍 | Battery Size ⚙️ | Federal Rebate 💸 | WA Rebate 💰 | Total Support 🧾 |
|---|---|---|---|---|
| Perth (Synergy) | 10 kWh | ~$3,500 | $1,300 | $4,800–$5,000 |
| Regional WA (Horizon) | 13 kWh | ~$4,800 | $3,800 | $7,300–$7,500 |
These estimates assume your battery is installed by an approved provider, meets program criteria, and is connected to a VPP.
This is now one of the most generous battery rebate setups in Australia particularly for households in regional areas served by Horizon Power.
Who’s Eligible for the WA
Battery Rebate?
The WA Residential Battery Scheme is designed to support a wide range of homeowners including some renters and home-based businesses as long as the battery meets the required property, product, and installer criteria. Here’s what you need to know:
Property & Account Requirements
- The system must be installed at a residential property in Western Australia
- The property must have an electricity account with Synergy or Horizon Power

- To receive the maximum WA rebate ($1,300 for Synergy / $3,800 for Horizon), your battery must be:
- On the approved list
- Have a usable capacity of 10 kWh or more
- Installed according to technical standards
The national average battery size is currently 12–13 kWh meaning many typical home systems will qualify for the full state rebate, assuming all other conditions are met.
Interest-Free Loans: What You
Need to Know
Households with a combined income of $210,000 or less may be eligible for an interest-free loan to help cover the upfront cost of installing a home battery. These loans are part of the WA Government’s Smart Energy platform and will be made available from 1 July 2025, alongside the rebate program. Here’s how the loan works:
- The maximum loan amount is $10,000
- The minimum loan amount is $2,000
- Loan terms are fixed at 10 years
- Applicants must pass a credit check and meet standard financial criteria
- Loan applications are assessed by the Scheme Administrator, not the WA Government
- The Scheme Administrator must hold an Australian credit license
- Repayments are made directly to the Scheme Administrator
- Borrowers who stay in good standing will not be charged fees
- Late fees may apply for missed or overdue payments
Loan financing will be delivered by Plenti, the government’s approved lending partner.
Step-by-Step Application Process
Choose a Battery System + an Approved Retailer and Installer
Before anything else, make sure you’re working with a properly qualified provider. To access the rebate:
- Your battery retailer must be a NETCC Approved Seller and be registered with the WA Residential Battery Scheme
- Your installer must hold the appropriate SAA (Solar Accreditation Australia) battery installation accreditation
- Your chosen battery system and inverter must be on the approved equipment list (to be released prior to launch)
Only retailers and installers who meet these conditions will be eligible to participate in the program and your rebate may be voided if the installation is not completed by an approved provider.
Confirm Rebate Eligibility
Your installer will verify your system design and VPP participation meet the requirements based on whether you’re a Synergy or Horizon Power customer.
Installation Takes Place
Installations must occur on or after 1 July 2025 to qualify. Any system installed before this date is not eligible for a rebate or loan.
Rebate Processed Automatically
The installer will submit documentation to claim the rebate on your behalf. There’s no separate application process for homeowners it’s all handled behind the scenes, with the rebate typically applied to your final quote or invoice.
If You’re Applying for a Loan
If you’re eligible for the interest-free loan (income ≤ $210,000), you’ll apply via the WA Smart Energy platform, with financing managed through Plenti. This application will include a basic credit check and assessment by the scheme administrator. Loan approvals are separate from the rebate and must be finalised before installation.
Conditions Apply
Important Conditions to Know
While the WA battery rebate is generous, there are several technical and administrative requirements that must be met to ensure eligibility and to avoid disappointment. Here’s what to keep in mind:
Installation Must Meet Strict Technical Standards
- Your system must be configured to participate in a Virtual Power Plant (VPP)
- Only approved battery models and inverters will qualify (list to be published before 1 July 2025)
- The installer must meet SAA battery accreditation standards
- The battery must be new, not second-hand or already installed
Retailer and Installer Requirements

Property Limitations
- Only one rebate per property
- Rebates do not apply to state- or institution-owned properties
- Long-term rentals are eligible, but must have landlord approval
- Home-based businesses qualify if the property is also the main residence
Rebate Declines Over Time
- The federal portion of the rebate will reduce annually until 2030
- Acting in 2025 or 2026 may result in thousands more in savings compared to waiting
- WA’s state rebate is expected to remain fixed in the short term — but may close once allocated funds are exhausted
Can You Stack the WA and Federal Battery Rebates?
Yes eligible households in WA can combine the state and federal battery rebates as part of a joint funding initiative.
This is one of the first coordinated battery incentive programs in Australia that formally allows stacking, giving Western Australian residents access to some of the highest total rebates in the country.
Here’s how it works.
Federal Rebate
- Up to $372 per usable kWh, capped at 50 kWh
- Delivered through the national battery rebate program
- Administered automatically by your installer (no direct application required)
WA State Rebate
- Delivered via Synergy (metro) or Horizon Power (regional)
- Paid as a top-up rebate, subject to meeting state-specific conditions
- Requires your participation in a Virtual Power Plant (VPP)
Stacking Outcome
| Provider 🏢 | Federal Rebate 💸 | WA Rebate 💰 | Total Rebate Available 📊 |
|---|---|---|---|
| Synergy | ~$3,500 (10 kWh battery) | Up to $1,300 | Up to $5,000 |
| Horizon Power | ~$4,800 (13 kWh battery) | Up to $3,800 | Up to $7,500 |
Stacking is automatic as long as your system, installer, and VPP participation meet the program requirements. The total combined rebate is factored into your installer quote you won’t need to apply separately for each.
Should You Act Now or Wait?
With battery rebates now available from both the WA and federal governments, the question many homeowners are asking is: “Should I install now, or wait?” Here’s what you should consider:
The Federal Rebate Will Step Down Over Time
The federal rebate which currently offers up to $372 per usable kWh is scheduled to reduce gradually every year until the program ends in 2030. That means the sooner you act, the more you’re likely to save.
WA Scheme Launches on 1 July 2025
The WA Residential Battery Scheme opens from 1 July 2025, and both the state and federal rebates are designed to support wider battery adoption across WA including regional and remote areas.
While there’s currently no official deadline, it’s still a smart idea to start planning early to:
- Understand your eligibility
- Choose a compliant system and installer
- Avoid the expected surge in installation demand later in the year
Battery Prices Are Stable But Installation Queues May Build
Battery prices in Australia are no longer falling significantly, and installation lead times are expected to increase once the WA scheme opens. Waiting too long could mean:
- Missing out on this year’s rebate tier
- Facing delays due to installer availability
- Competing with a rush of last-minute applications
Our Take:
If you’re in WA, 2025 is the best window we’ve seen yet to lock in a discounted battery system especially with access to both rebates and a no-interest loan (for eligible households).
