Western Australia’s Residential Battery Scheme launches by 1 July 2025, offering rebates of up to $7,500 and no-interest loans to support home energy storage. Here’s how to qualify, maximise your savings, and prepare early.
Overview of the WA Home Battery Rebate Program
The WA Government has committed $387 million to help households install battery storage systems. Under the Residential Battery Scheme, eligible homeowners on the Synergy and Horizon Power networks can access:
- Up to $5,000 rebate for Synergy customers
- Up to $7,500 rebate for Horizon Power customers
- Interest-free loans up to $10,000 for low-to-middle income households
But funding is limited. Only 20,000 households across WA — from over 900,000 dwellings — are expected to benefit in the initial rounds. Acting early greatly improves your chance of securing financial support.

Battery Rebate Amounts: Breakdown by Provider
| Customer Type | Rebate Per kWh | Max Capacity | Max Rebate | Total Households |
|---|---|---|---|---|
| Synergy (Metro & SW WA) | $500 | 10kWh | $5,000 | 19,000 |
| Horizon Power (Regional WA) | $750 | 10kWh | $7,500 | 1,000 |
Why Are Horizon Customers Getting More?
Horizon Power services regional and remote WA, where electricity infrastructure is more expensive and less reliable. Higher rebates reflect the greater cost of batteries in these off-grid or microgrid locations, offering improved energy security and cost savings.
What Can the Interest-Free Loan Cover?
Alongside rebates, the scheme includes means-tested loans to help eligible households afford a system. These loans can be used for:
- Battery-only systems
- Combined solar + battery packages
- New or replacement solar panels (only when bundled with a battery)
Loan Details:
- Amount: $2,000 – $10,000
- Term: Up to 10 years
- Eligibility: Income-tested (criteria pending)
The rebate is not income-tested, meaning any eligible household can apply — but loans will only be available to lower- and middle-income earners.
Eligibility: Who Can Apply?
To qualify for the scheme, applicants must:
- Be a resident of Western Australia
- Be a customer of Synergy or Horizon Power
- Install a VPP-ready battery system with at least 5kWh usable storage
- Use a WA-based accredited retailer or installer
- Meet all technical, safety, and warranty standards (TBC)
Also eligible:
- Home businesses
- Landlords, if they provide proof of a long-term tenancy agreement
Not eligible:
- Government-owned properties
- Financial institutions, telcos, and resource companies

What Does VPP-Ready Mean
A Virtual Power Plant (VPP)-ready battery must:
- Be connected to the internet
- Be able to respond to signals from the grid
- Support future participation in energy-sharing networks
This ensures batteries can help stabilise WA’s power grid in real time.
How the Rebate Scheme Will Roll Out
- The scheme will be rolled out in multiple rounds, beginning by 1 July 2025
- A third-party program administrator will manage applications and compliance
- Retailers will be required to publish pre-rebate pricing for transparency
- Participating installers will undergo ongoing audits to ensure quality and compliance
How to Prepare for the WA Battery Rebate
Rebate demand will likely exceed supply. Follow these steps to be installation-ready before the rush.
1. Install Solar (or Plan to Bundle)
Homes with existing solar will be in a stronger position to qualify. If you don’t already have panels, install them now or bundle them with a battery to maximise savings.
2. Choose a Hybrid Inverter
A hybrid inverter supports both solar input and future battery integration. It simplifies system expansion and avoids delays tied to grid approval.
- DC-coupled systems integrate faster
- Hybrid setups reduce install time when batteries are added later
3. Pre-Order Your Battery
To secure stock and fast-track compliance, pre-order your battery in advance. With only 20,000 rebates available, early preparation ensures you’re at the front of the line.
4. Work With a Trusted WA Installer
The rebate requires WA-based installers — but a local company also offers:
- Faster turnaround
- Localised aftercare and warranty support
- Knowledge of WA compliance standards
Avoid national operators chasing rebate programs. Choose a provider with proven experience in WA.
Battery Cost Tip: Compare Value by Cost-per-kWh
When selecting a battery, don’t focus only on price. Cost-per-kWh helps you understand the real value.
For example:
- A 10kWh battery costing $5,000 = $500 per kWh
- A 5kWh battery costing $7,500 = $1,500 per kWh
A lower cost-per-kWh generally means better long-term value — especially when paired with a strong performance warranty.
The Federal Solar Rebate Still Applies
The Small-scale Renewable Energy Scheme (SRES) can reduce solar panel costs by thousands. While it steps down slightly each year, it remains a major saving — and can be used in addition to the WA battery rebate.
Why You Shouldn’t Wait
Delaying installation until the scheme launches may cost you more:
- Higher power bills in the meantime
- Price hikes due to increased demand
- Longer installation wait times
- Limited stock of quality batteries and hybrid inverters
Installing a hybrid system now locks in immediate solar savings — and positions you to claim the battery rebate as soon as it opens.
Can You Combine Federal and WA Rebates?
Right now, only the WA rebate is confirmed. While a federal battery rebate has been proposed, it’s not guaranteed. If both become available, combining incentives will depend on each program’s eligibility criteria — expected closer to rollout.
Stay Updated: Register Your Interest
Stay ahead of the rollout by registering your interest at wa.gov.au. You’ll receive updates as the scheme finalises and be notified when applications open.
Final Thoughts
The WA Home Battery Rebate is a rare opportunity to slash your power bills and future-proof your energy setup — but spaces are limited.
Installing a hybrid system now and working with a trusted WA-based installer gives you a clear edge when the scheme launches. Be ready, be early, and reap the benefits of secure, affordable home energy storage.
