WA Home Battery Rebate

The State Government’s promised WA Home Battery Rebate is now confirmed. Although it officially launches on 1 July 2025, solar and battery installers are taking pre-orders now. Demand is high.

Only 100,000 homes can claim the rebate, and once the cap is reached, it’s gone. That’s triggered a huge surge in orders across WA.

What’s Confirmed for the WA Government’s Home Battery Scheme?

One of the biggest benefits for WA homeowners is that you can claim both the new Federal Battery Rebate and the WA State Rebate together — delivering major savings.

• The Federal Rebate offers $400 per kWh up to 50 kWh, capped at 100 kWh battery size.

• The WA Rebate offers up to $130 per kWh (Synergy) or $380 per kWh (Horizon Power), up to 10 kWh.

This means a typical WA household could receive:

• Up to $5,000 when combined with the new national Battery Rebate and you’re with Synergy
• Up to $7,500 when combined with the new national Battery Rebate and you’re with Horizon Power
• Interest-free loan of up to $10,000 (conditions apply)
• Rebate amounts scale with battery size

Why is the WA Government Offering a Home Battery Rebate? 

The WA Government has positioned the scheme as both a cost-of-living relief measure and to help the grid decarbonise, so a step toward a more sustainable, reliable electricity system. 

$387 million has been pledged by the WA Government for the scheme. The budget covers the rebates, loans and also $50 million for local battery manufacturing.

Premier Roger Cook has stated “it’s anticipated the Scheme will more than double the number of residential batteries currently installed in WA homes”.

With about 15,000 batteries already installed in WA homes, the 100,000 rebates on offer should easily achieve that goal. 

The WA Home Battery Scheme aims to address the electricity system’s challenges:

• High rooftop solar uptake: WA has one of the highest rates of rooftop solar in Australia, which creates grid management issues, especially during daytime solar generation peaks. 
• Rising electricity costs: Households are seeking ways to reduce their home expenses.
• Grid reliability concerns: The scheme aims to reduce pressure on the grid during peak demand periods.

A number of States have also launched battery incentives over the last few years. Here’s how WA’s scheme stacks up: 

• ACT: Sustainable Household Scheme – zero-interest loans – $2,000 to $15,000 – for energy-efficient upgrades. Includes solar systems and batteries.  

• NSW: Peak Demand Reduction Scheme (PDRS) – Launched in 2024, the program provides $1,600 to $2,400 off the cost of a battery. An extra $250 to $400 is available for households that connect their batteries to a Virtual Power Plant (VPP).  Empowering Homes Program – interest-free loans up to $14,000 for solar-battery systems to eligible households with incomes under $180,000.  

• NT: Home and Business Battery Scheme – since December 2024 this grant was increased to $400 per kilowatt-hour of usable capacity, up to a maximum of $12,000.

• QLD: Battery Booster Program – program concluded in May 2024. Sign-up below for battery rebate alerts.

• SA: Home Battery Scheme – closed in 2024. Again, you can register for alerts below.

• TAS: as of May 2025, there are no dedicated state battery rebate for Tasmania.

• VIC: Solar Homes Program – interest-free loans up to $8,800 for battery installations.  

Final Thoughts

The WA Residential Solar Battery Scheme is a substantial step toward making battery storage viable for more WA households.

While the scheme’s effectiveness will depend on its final design and rollout (soon to be announced), the WA Labor government has positioned the policy as a key part of its strategy to address cost-of-living pressures and support the state’s renewable energy transition.
