The Western Australia (WA) Home Battery Rebate 2025, officially the WA Residential Battery Scheme, is a game-changing initiative to make home battery storage affordable. With a $387 million budget, it offers rebates and interest-free loans to help households cut electricity bills, boost solar energy use, and support a cleaner energy grid.
Premier Roger Cook announced the solar battery rebate during WA Labor’s election campaign. The WA Government has promised to implement a $387 million program that includes rebates of up to $5,000 for Synergy customers and up to $7,500 for Horizon customers. It’s estimated that each household can save up to $1,500 per year by installing a solar battery. This battery scheme aims to help WA homeowners purchase a solar battery for their solar system, allowing households long-term cost of living relief.
Program Overview
Launching by July 1, 2025, the WA Home Battery Rebate aims to support approximately 20,000 households across the state. It addresses rising electricity costs, enhances grid reliability, and promotes decarbonization. Key features include:
- Rebates: Up to $5,000 for Synergy customers and $7,500 for Horizon Power customers, based on battery size.
- Interest-Free Loans: Up to $10,000 for low-to-middle-income households, repayable over 10 years.
- Funding: $387 million, with $50 million for local battery manufacturing.
The rebates are non-means-tested, making them widely accessible, while loans are means-tested to prioritize lower-income families.
Comparison Table: Synergy vs. Horizon
Feature | Synergy (Metro/SWIS) | Horizon Power (Regional/Remote) |
Maximum rebate | $5,000 (at $500/kWh × 10 kWh) | $7,500 (at $750/kWh × 10 kWh) |
Eligible households | 19,000 | 1,000 |
Account needed | Synergy residential account | Horizon Power residential account |
Application opens | By 1 July 2025 (staged rounds) | From 1 July 2025 (regional rollout)wa.gov.au |
Loan eligibility | Means-tested loans up to $10k | Means-tested loans up to $10k |
- Synergy Customers: Urban areas like Perth, connected to the South West Interconnected System.
- Horizon Power Customers: Regional and remote areas, where higher rebates reflect higher installation costs in off-grid or microgrid locations.
Example:
- If you purchase a 5kWh battery, the rebate would be:
5 × $500 = $2,500 - If you purchase a 10kWh battery, the rebate would be:
10 × $500 = $5,000
we strongly recommend having a “Battery Ready” solar system installed before 1 July 2025 to maximise your chances of securing the battery rebate.
Who’s Eligible?
- Residential WA homes (including home businesses) with an electricity account in their name. You must be a Synergy (metropolitan) or Horizon Power (regional/remote) customer.
- Renters/Landlords: Landlords can claim one rebate per property if they provide a long-term lease agreement. (Each eligible property can claim only once.)
- Home businesses are eligible if installed at a qualifying residential address.
- Existing solar owners: You can apply even if you already have solar; upgrades or battery retrofits (≥5 kWh) are eligible.
Who’s Ineligible
- Excluded: Government-owned properties,
- banks/financial institutions, telecommunications and mining/resource companies. Only residential accounts qualify – not commercial/industrial.
- Pre-existing batteries: Batteries installed before July 2025 do not qualify wa.gov.au.
The program supports new installations, replacements, and additional battery systems.
Program Timeline & Rollout
- Launch Date: On or before 1 July 2025. The exact start will be announced closer to the date.
- Staged Rounds: Applications will open in waves (to manage demand) starting from mid-2025 wa.gov.au. Stakeholders will give advance notice of each round.
- Duration: The scheme (20,000 rebates) will run until funds are exhausted. Based on announced pledges (~$387 million), it’s expected to support roughly 20,000 installations
- Sign Up: Interested households and businesses should register their interest now (WA Battery Scheme mailing list) to get updates. Register as a household here or as a retailer/installer here.
How to Prepare
To secure the rebate, act early due to limited funding (20,000 households out of over 900,000 dwellings). Follow these steps:
- Install Solar Now: If you lack a solar system, install one with a hybrid inverter compatible with battery storage.
- Pre-Order Batteries: Contact a WA-based installer to pre-order, as demand will be high.
- Compare Battery Options: Choose VPP-ready batteries with at least 5 kWh capacity, evaluating cost-per-kWh.
- Work with Local Installers: Ensure installers are accredited and offer warranty support.
- Register for Updates: Sign up for alerts at wa.gov.au to stay informed.
Approved Equipment & Technical Specs
- Approved List: Only batteries and inverters on the official approved equipment list will qualify (the list will be published before launch).
- Minimum Size: Battery systems must be at least 5 kWh usable capacity. (This aligns with typical home batteries. Batteries below 5 kWh will not qualify.)
- Standards: Batteries must meet Australian and local grid standards. In practice, this means using CEC-accredited, SAA-approved equipment. International or off-spec products won’t qualify.
- Virtual Power Plant (VPP) Ready: Systems must be VPP-capable. That means they must be able to connect to the internet and respond to grid signals in real time. This ensures they can join future energy-sharing networks to help stabilize the grid.
- Safety/Warranty: Installations must meet all safety, performance, and warranty standards (details still in development). Installers will test and certify VPP connectivity and compliance.
- Batteries capacity: with a larger capacity than 10kWh, that are on the approved equipment list (list not announced yet), are eligible for the maximum rebate of $5000 or $7500. The national average battery size is between 12-13 kWh.
- Existing vs New: New battery purchases, additions (expanding an existing system) or replacements (swapping an old battery for a new one) are all eligible. (You cannot claim a rebate simply for maintaining an old battery.)
Installer/Business Accreditation
- WA-Based Businesses: Retailers and installers must have a Western Australian business address to participate. (No out-of-state firms chasing subsidies.)
- Registration: Installers will need to register with the scheme (a list of participating installers will be published). At minimum, they should be Clean Energy Council (CEC) accredited for battery installations.
- Integrity Standards: Businesses must meet financial and performance standards continuously. They’ll publish pre-rebate pricing to avoid marked-up quotes, and there will be compliance audits and testing.
- Training: Installers should be familiar with VPP configuration and grid compliance. Retailers should advise clients on combining panels + batteries (a combined solar/battery purchase can be covered by the loan).
- Opportunities for Retailers: Solar businesses can register interest now and pre-qualify customers. By auditing homes’ energy use and advising on system size, they’ll be first in line when rebates open.
How to Apply
- Through Installers: WA will likely require applications via approved solar retailers/installers (to be announced). Households should select a WA-based, accredited installer.
- Documentation: While final rules are pending, you will need proof of residency and electricity account (Synergy/Horizon bill), ID, and for landlords a valid lease. Keep your rates notice, tenancy agreement, and meter details ready.
- Process: Once applications open, eligible customers submit a formal application (likely online) with supporting documents. After approval, the installer can fit the approved battery and claim the rebate/loan on your behalf.
- Application Period: Not continuous; you’ll apply in the announced round for your area. Sign up for email updates to know exactly when your turn comes.
- FAQs: Key questions – “Can I apply now?” No, applications aren’t open until mid-2025. “How many rebates per house?” One per property. “Am I eligible if I already have a battery?” No – only new purchases after scheme start qualify.
Program Budget & Cap
- Funding: ~$387 million over 10 years has been committed. This covers rebates, loans, and a $50 million Battery Manufacturing Program (grants/loans to local battery makers).
- Household Reach: Expected to install ~20,000 home batteries (doubling the current ~10,000 installations)
- Round Caps: Early rounds may be limited by geography or timing. For example, the first 19,000 rebates are slated for Synergy customers, 1,000 for Horizon. Each round will announce how many rebates remain.
- Timing: Budget will be allocated round-by-round. It’s possible some later rounds will depend on uptake speed (reassess yearly).
Preparing for the Rebate: Steps to Take Now
To maximize your chances of securing the rebate and optimizing your solar battery system, follow these steps:
- Assess Your Energy Needs:
- Review your electricity bills to understand your daily consumption and peak usage times.
- A 10 kWh battery is ideal for most households, covering evening demand and peak shaving.
- Install or Upgrade Your Solar System:
- If you don’t have solar, install a 6.6 kW system (eligible for a ~$2,500 federal STC rebate) with a hybrid inverter.
- If you have solar, ensure your inverter is battery-compatible or upgrade to a hybrid model.
- This would be a two-part installation. Install a hybrid inverter now and then add the batteries to your system once the scheme commences.
- Choose a Trusted Installer:
- Look for installers with SAA/CEC accreditation, local experience, and a track record of quality installations.
- Verify their eligibility to participate in the scheme (WA-based, compliant with standards).
- Understand Battery Features:
- Prioritize energy density and warranty (e.g., 10-year performance warranties).
- Avoid overpaying for fringe features like blackout protection unless critical for your needs.
- Monitor Updates:
- Check for federal rebate updates, as eligibility criteria are still emerging.
Challenges and Controversies
While promising, the program faces challenges:
- Limited Funding: Only 20,000 households will benefit initially, creating competition.
- Pending Details: Income thresholds for loans and final installer standards are still unclear.
- Industry Disruption: As noted in an ABC News article, the announcement has led some customers to delay purchases, causing temporary business slowdowns for installers.
Additional Rebate Opportunities
Beyond the state program, consider:
- Federal Battery Rebate: A proposed 30% discount (up to $350 per kWh for 5–50 kWh batteries), not means-tested, VPP-ready, valued at $2.3 billion.
- Small-scale Renewable Energy Scheme (SRES): Reduces solar installation costs, combinable with the WA rebate.
- Manufacturer Rebates: Currently, no major-brand rebates exist, but monitor for updates.
