Western Australians have a new reason to get excited about solar and battery storage. The New WA Residential Battery Scheme is here — and it’s set to change how households store and use solar energy. Whether you’re just starting your solar journey or already have panels on your roof, this new initiative offers a powerful opportunity to take control of your electricity usage, reduce bills, and boost energy independence.
In this blog, we explain what the new scheme is, how it works, who is eligible, how much you can save, and most importantly — how to apply.
What Is the New WA Residential Battery Scheme?
The WA Government’s Residential Battery Scheme is a financial incentive program aimed at helping homeowners install battery storage systems to work alongside their solar panels. The goal is simple: shift more households towards energy self-sufficiency, reduce peak demand on the grid, and support the transition to renewable energy.
This is part of WA’s broader energy strategy and its commitment to net‑zero emissions by 2050.
How Much Is the Rebate or Incentive?
Eligible homeowners can access:
- A rebate of up to $5,000 for Synergy customers and up to $7,500 for Horizon Power customers toward the cost of a battery storage system.
- No‑interest loans of up to $10,000 for eligible households with an income under $210,000 per year.
The exact rebate amount depends on battery size, your electricity provider, and compliance with scheme terms.
Example: A 10 kWh battery could qualify for a full $5,000 rebate under Synergy or up to $7,500 under Horizon Power.
Who Is Eligible for the Scheme?
To qualify for the Residential Battery Scheme in WA, you must:
- Be a homeowner living in Western Australia with a Synergy or Horizon Power electricity account.
- Already have a solar PV system installed, or install one alongside the battery.
- Purchase the battery from an approved supplier and have it installed by a Solar Accreditation Australia (SAA) accredited installer.
- Agree to participate in a Virtual Power Plant (VPP) — this is mandatory to receive the rebate.
- Use approved products and vendors listed in the scheme database.
Why Install a Battery with Solar?
Installing a solar battery in WA is no longer just an environmental decision — it’s also a smart financial move. Here’s why:
Energy Independence – Store excess solar power during the day for use at night.
Lower Electricity Bills – Maximise solar usage instead of exporting to the grid for a low feed-in tariff.
Backup Power – Certain batteries offer blackout protection depending on the system design.
Faster ROI – Government incentives significantly reduce payback time.
Which Batteries Are Eligible?
To qualify for the rebate, your battery must:
Be listed on the Solar Accreditation Australia (SAA) Approved Battery List
Have a minimum usable storage capacity of 5 kWh
Be installed by a scheme-authorised, CEC-accredited installer
Popular eligible brands include:
- Tesla Powerwall
- Alpha ESS
- Sungrow
- Huawei
- SAJ
Virtual Power Plant Participation (Mandatory)
To receive the rebate or loan, all battery systems must be enrolled in a Virtual Power Plant (VPP):
Synergy customers participate via Synergy’s “Battery Rewards” program.
Horizon Power customers are enrolled in the “Community Wave” VPP.
These programs allow the utility to draw on battery power during peak demand events and help stabilise the grid.
