WA Battery Rebate Explained: Amount, Eligibility & How To Apply

EcoFlow

The WA Battery Rebate offers eligible households up to $1,300 for Synergy customers or up to $3,800 for Horizon Power customers towards an eligible home battery system. This guide explains who qualifies, how VPP and no-interest loan requirements work, and how to apply so you can understand the available support before choosing a battery.

Key Takeaways

  • The WA Battery Rebate can reduce the upfront cost of an eligible home battery and may be combined with the federal battery incentive.

  • Eligibility relies on the property, electricity provider, approved system, accredited scheme vendor, and VPP participation.

  • Eligible households may also access a no-interest loan to help cover installation costs.

  • Rebate applications are generally submitted through an accredited scheme vendor.

How Much Is the WA Battery Rebate?

Eligible Synergy customers can receive up to A$1,300, while Horizon Power customers can receive up to A$3,800 through the WA battery rebates. Qualifying households may also apply for a no-interest loan of up to A$10,000.

Battery Rebates

The WA Residential Battery Scheme is calculated on up to 10kWh of usable battery capacity:

  • Synergy: A$130 per kWh

  • Horizon Power: A$380 per kWh

Larger batteries can still qualify, but the WA rebate is capped at 10kWh. Eligible systems may also receive federal support through the Cheaper Home Batteries Program. From 1 May 2026, federal support tapers above 14kWh, with subsidy rates scheduled to decrease every six months.

No-Interest Loans

Eligible households with a combined annual income below $210,000 may apply for a no-interest loan with the following terms:

  • Loan amount: $2,001 to $10,000.

  • Repayment term: 3 to 10 years.

  • Interest and early repayment: No interest or early repayment fees apply.

  • Approval and fees: Applicants must meet credit assessment and responsible lending requirements, and a capped late payment fee may apply.

The loan can help eligible households spread the remaining cost of a battery system over a longer period.

Who Is Eligible for the WA Battery Rebate?

To access the WA Battery Rebate, households must meet the eligibility criteria set by the WA Battery Scheme. These requirements cover factors such as the property location, electricity provider, battery system, and installation conditions. Checking the requirements before applying helps ensure the battery installation satisfies the scheme standards.

Household and Property Requirements

The WA Battery Scheme is available to eligible Western Australian residents who meet the household and property requirements. Applicants must be aged 18 or older, be an Australian permanent resident, and have an eligible electricity account with either Synergy or Horizon Power. They must also complete identity verification and agree to the installation of a battery system at their property.

To qualify for the WA Battery Rebate, applicants generally need to:

  • Have an eligible residential property in Western Australia.

  • Hold an eligible electricity account with Synergy or Horizon Power.

  • Choose an approved battery system that meets the scheme requirements.

  • Purchase and install the system through an approved vendor and eligible installer.

  • Meet the scheme’s Virtual Power Plant (VPP) participation requirements, where applicable.

Additional conditions may apply depending on property ownership, tenancy arrangements and the selected battery system, so applicants should confirm the current scheme requirements before proceeding.

Approved Battery and Installer Requirements

To receive the WA Battery Rebate, the battery system must have at least 5 kWh of usable capacity and meet the scheme’s eligible product requirements. This includes being listed on the relevant Synergy or Horizon Power Supported Solution List and on the Clean Energy Council’s approved batteries and inverters list.

Applicants can check approved battery products and accredited installers through the scheme resources provided by Plenti, the third-party administrator responsible for managing the WA Residential Battery Scheme.

Virtual Power Plant (VPP) Participation Requirements

Participation in an eligible Virtual Power Plant (VPP) is required to receive the WA Battery Rebate. A VPP connects participating home batteries so stored energy can be coordinated to support the electricity grid when needed.

Applicants must join an eligible VPP product and enter into the relevant VPP agreement. Synergy customers can choose a VPP offered by Synergy or another provider that meets WA Government requirements, while Horizon Power customers must join an eligible Horizon Power VPP.

Battery Installation and Grid Requirements

Battery installations must meet the technical requirements that apply to their electricity network to remain eligible under the WA Battery Scheme. Installations in Synergy’s grid-connected area must comply with the relevant Synergy and Western Power requirements, while those in Horizon Power’s grid-connected area must meet Horizon Power’s applicable technical requirements.

These requirements cover areas such as battery connection, system functionality and network compliance.

How To Apply for the WA Battery Rebate

Applying for the Battery Rebate WA requires several steps, from checking eligibility to selecting approved products and completing the application process. Following the required steps helps ensure your battery installation complies with the scheme requirements and allows your application to be processed smoothly.

Review the Eligibility Criteria and Applicant Requirements

Before starting the application, applicants should review the eligibility criteria and scheme information to confirm they meet the requirements. This includes checking household eligibility, property conditions, electricity provider requirements, and approved installation standards.

Get Quotes From Approved Battery Retailers

Applicants need to get quotes from approved battery retailers to discuss suitable battery products and available financing options, including no-interest loans. Working with an approved vendor ensures the selected system meets the WA Residential Battery Scheme requirements.

Choose an Approved Battery and Inverter System

Choose a battery and inverter combination that meets the scheme requirements. Battery modules must be on the Clean Energy Council Approved Battery List, while the inverter must appear on the relevant Synergy or Horizon Power supported solutions list for your location. Your selected vendor will then submit the rebate application on your behalf.

Submit the Application Through Your Battery Vendor

Once the battery system and installer have been selected, the approved battery vendor will submit the rebate application on behalf of the applicant. Applicants should provide the required information and complete any verification steps requested during the process.

Apply for a No-Interest Loan (If Required)

If you also want a no-interest loan, your installer or vendor will submit the application to Plenti on your behalf. Plenti, the scheme administrator, will then contact you directly to verify your household income and complete the required credit and lending checks.

How to Maximise Your WA Battery Rebate Savings

Making the most of the WA Battery Rebate involves more than accessing the upfront support. Households can improve the value of their battery investment by combining available incentives, choosing the right system, and managing energy usage effectively.

Combine the WA Battery Rebate With the Federal Battery Incentive

Eligible households may be able to combine the WA Battery Rebate with the federal Cheaper Home Batteries Program to reduce upfront installation costs. Before choosing a system, confirm how both incentives apply to the battery capacity and configuration you are considering.

Choose the Right Battery Capacity

Battery size affects both system cost and available support. The WA rebate is capped based on up to 10 kWh of usable battery capacity, so a larger system will not increase the state rebate beyond the maximum. When choosing a home battery storage system, balance available benefits with your solar generation, electricity use and backup needs.

Understand VPP Participation

VPP participation is a requirement for households accessing the WA rebate. Depending on the provider and plan, households may also receive credits or other benefits when stored energy is used to support the grid. Check the VPP terms, export arrangements and battery control conditions before joining.

Balance Rebate Value With Backup Needs

To get better value from the WA Battery Rebate, size your eligible battery baesed on your household’s solar generation and everyday energy use rather than backup needs alone. If you also want flexible power during outages, a portable power station can complement your home energy setup for selected appliances.

The EcoFlow DELTA 3 Max Plus Portable Power Station offers 2,048Wh capacity and 3,000W AC output, making it appropriate for essential household loads and shorter backup periods. It can also expand up to 10kWh if more runtime is needed.

Conclusion

The WA Battery Rebate can make home battery storage more accessible for eligible Western Australian households, but qualification depends on the property, approved system, accredited vendor and VPP participation. Before applying, check the current scheme requirements, available loan or federal incentive support, and choose a battery that suits your energy use, solar setup and backup needs, while comparing other home backup generator options where relevant.

FAQs

Do I Have to Join a VPP to Get the WA Battery Rebate?

Yes. If you want to claim the WA Battery Rebate, you’ll need to join an eligible VPP program. Before buying a battery, check that your chosen system supports the VPP available through Synergy or Horizon Power. You should also review how the VPP may control or export stored energy, so you understand the conditions before committing.

Is installing a solar battery worth it in Western Australia?

It can be worthwhile if you have excess solar generation during the day and regularly use electricity in the evening. Before installing a battery, compare the upfront cost after rebates with your expected bill savings, backup needs, VPP terms and battery warranty. A rebate can improve the value of a system, but the actual payback will depend on how much stored energy your household can use.

Will the solar battery rebate decrease in 2026?

If you are installing a battery in WA in 2026, it is important to distinguish between the WA Battery Rebate and the federal battery incentive. The WA rebate continues under its current scheme settings, while the federal Cheaper Home Batteries Program changed from 1 May 2026, when the STC factor fell to 6.8 per kWh and support began tapering for battery capacity above 14 kWh. Check both incentives when comparing quotes, as the federal discount available can depend on the installation date and battery size.

Can I Claim the WA Battery Rebate After My Battery Is Installed?

If your battery was installed before 1 July 2025, it is not eligible for the WA Battery Rebate. If you are planning a new installation, check your eligibility and arrange the rebate through an approved vendor before proceeding. This helps ensure the battery, installer and application meet the scheme requirements rather than relying on a retrospective claim.
