Updated Guide to WA Government Incentives for Solar & Battery Storage – 2025

With the cost of energy going up and being more pressing, the Western Australian Government has introduced a variety of programs that have made it cheaper to enjoy clean energy. While the Federal Government also introduced its Cheaper Home Batteries Program, WA residents now have a golden chance to benefit from stacked rebates and interest-free loans. In this article, we give you a full Updated Guide to WA Government Incentives for Solar & Battery Storage (2025 Edition), so that you can get a clear idea of how much you can save and how to become eligible.

Why WA Solar Battery Incentives 2025 Matter

The WA solar battery incentives 2025 is one of the most important energy policies to have been rolled out in recent times. The incentives are aimed at bringing down the initial cost of battery storage systems, making solar power more economically feasible, and making WA’s energy grid more robust by promoting the adoption of batteries.

With these incentives, homeowners, businesses, and even community centers can finally realize the long-awaited financial viability of solar + battery storage systems. Combining the Federal and WA programs enables saving thousands of dollars, and with that, makes battery installation more appealing than ever before.

Federal Solar Battery Rebate Explained (2025)

As from 1 July 2025, the Australian Government officially commenced the Cheaper Home Batteries Program, implemented through a $2.3 billion Small-scale Renewable Energy Scheme (SRES) expansion. The rebate operates similarly to rooftop solar’s STC system, providing discounts on the purchase price of battery systems upfront.

Important Details:

• Commencement date: 1 July 2025

• Rebate amount: 9.3 STCs per usable kWh, up to the first 50 kWh

• Current value: Around $344 per usable kWh (based on $37 STC price)

• Typical savings: $4,000 off a standard 11.5–13.5 kWh battery

• Eligibility: Homeowners, small businesses, community facilities

• Means-tested?: No, available to all property owners

• Battery requirements: 5–100 kWh size; must be paired with rooftop solar

This rebate is applied directly to your invoice by accredited installers, removing the hassle of government paperwork.

WA Residential Battery Scheme 2025

The WA residential battery plan is a state-level program that came in concurrently with the federal scheme. The WA Government has pledged $337 million to assist 100,000 homes in installing batteries.

Breakdown of Rebates:

• Synergy Customers: $130 per kWh, up to $1,300 (limited to first 10 kWh only)

• Horizon Power Customers: $380 per kWh, up to $3,800 (limited to first 10 kWh only)

• Delivery: Applied upfront through approved installers

• Eligibility: Homeowners, renters with consent, landlords with long-term renters, and home businesses

This renders WA’s program among the most generous in Australia, especially for regional homes covered by Horizon Power.

WA Solar Rebates and Incentives Combined with Federal Initiative

One of the strongest advantages of 2025 is that homes can stack WA solar rebates and incentives with the federal program. This stacking can literally slash upfront expenses.

Example (10 kWh battery):

• Synergy Customer: $1,300 (WA) + ~$3,440 (Federal) = ~$4,740 total savings

• Horizon Customer: $3,800 (WA) + ~$3,440 (Federal) = ~$7,240 total savings

Through these combined programs, certain households will save over 50% of the initial cost of a new battery system.

Synergy Solar Battery Rebate WA

For Sydney customers on the Synergy network, the Synergy solar battery rebate WA provides up to $1,300 from a new system. Though less than Horizon’s, this rebate still cuts the initial cost of installation considerably when paired with the federal program.

Key is that the rebate is applied to the first 10 kWh of capacity. It is particularly worth it for households wanting to install medium-sized batteries between 10–13 kWh.

Horizon Power Battery Rebates WA

Regional and remote homes gain the most from the Horizon Power battery rebates WA program. Consumers receive up to $3,800 in state-level incentives, making battery storage significantly more affordable in regions where energy reliability is paramount.

These rebates are higher, as they are a response to regional energy supply challenges, where more frequent power outages and increased infrastructure costs are the norm. In subsidising batteries across these regions, the WA Government is assisting in stabilising local grids and enhancing energy security.

WA Interest-Free Solar Loans

In addition to rebates, homes can take advantage of WA interest-free solar loans to further reduce the financial load. These loans come with 0% interest, allowing families to stretch payments over several years.

Loan Details:

• Amount: $2,001 – $10,000

• Term: 3–10 years

• Eligibility: Households with income under $210,000

• Covered systems: Batteries, solar + battery packages, hybrid inverters

By combining rebates with loans, many families will face little to no upfront cost when installing a new battery system.

Eligibility for WA Solar Battery Incentives 2025

To qualify for the WA solar battery incentives 2025, applicants must meet specific requirements:

• Be a Synergy or Horizon Power customer

• Be an Australian permanent resident aged 18+

• Replace an existing or new battery (5–100 kWh)

• Utilize only CEC-approved equipment and installers

• Enroll the battery in a Virtual Power Plant (VPP)

Tenants, residents, landlords, and home businesses can all be eligible as long as they fulfill the above conditions.

Virtual Power Plant (VPP) Requirements

One of the core components of both WA and federal schemes is that batteries must be VPP-enabled. A Virtual Power Plant is a system of interlinked batteries which are able to assist the grid in peak times.

To be eligible:

• Battery needs to be internet-enabled

• System needs to be able to respond to grid operator command

• VPP participation is compulsory under WA’s scheme

This means that domestic batteries are not just benefiting the individual but assisting in stabilising WA’s electricity grid.

Cost Example: Combining WA and Federal Incentives

Here’s how the incentives stack up for a 10 kWh battery in 2025:

This example shows how powerful the combined programs can be. Some households can install a system with no upfront cost, paying it back interest-free over time.

Selecting the Right Battery in 2025

With so many rebates out there, the market will probably be flooded with cheap, low-quality products. It is essential to select systems that are:

• On the WA Approved List

• VPP-compatible

• Supported by a minimum 10-year guarantee

• Highly rated by other Australian customers

The cheapest option might result in inferior performance and greater expenditure in the long term.

Why Horizon Customers Get Higher Rebates

Remote WA households have more expensive energy and inferior grid infrastructure. By providing greater rebates through WA Horizon Power battery rebates, the state government is tackling these special challenges while promoting increased use of battery systems where they are needed most.

Long-Term Impact of WA Solar Battery Incentives 2025

The WA solar battery rebates 2025 are one of the most significant policies ever brought forward to advance Australia’s clean energy future. By aligning with state-level rebates and the Federal Government’s Cheaper Home Batteries Program, these programs have the potential to change the way households produce, store, and use electricity for generations to come.

Probably one of the most direct advantages is lower household energy bills. By reducing initial costs by thousands of dollars, solar batteries are made much more accessible to families. They once installed, the systems enable homeowners to save excess sun-generated electricity during the day and utilize it at times of high demand, when electricity rates tend to be higher. In the long run, this amounts to substantial savings, which makes solar batteries an economical option as much as an eco-friendly one.

A second important consequence is the decreased dependence on the power grid. As an increasing number of homes take up solar + battery systems, they are able to satisfy a larger proportion of their own energy requirements independently. For local communities, especially those supplied by Horizon Power, this means higher energy security and less interruption during power cuts.

At a wider level, the incentives will enhance grid stability throughout WA. By mandating batteries to be Virtual Power Plant (VPP)-ready, the government puts in place a system that allows thousands of individual systems to collaborate and supply backup energy at times of peak demand or in an emergency. This combined support enhances the overall energy infrastructure of the state and takes stress off fossil-fuel power stations.

Lastly, these initiatives shall significantly reduce carbon emissions. By promoting clean, renewable energy storage, WA shall become less reliant on coal and gas, facilitating the state’s shift towards a more sustainable future.

In short, the WA solar battery incentives 2025 are not simply about saving money today — they are a long-term transition to affordability, resilience, and sustainability, and 2025 is a great year for homeowners to invest in solar and battery storage.
