Reducing the cost of home battery systems was a key promise in Labor’s election platform.
Now, following a decisive victory by the Albanese government, many Australians are eager to learn more about the Cheaper Home Batteries Program.
In this article, we break down the potential savings, rollout timeline, and the benefits the program offers—whether or not you already have solar panels installed.
Understanding Labor’s $2.3 Billion Home Battery Subsidy
Labor’s new $2.3 billion battery subsidy program is designed to support Australians who already have rooftop solar, as well as those looking to install a new solar-plus-battery system.
The program is not means-tested, making it accessible to households, businesses, and community facilities—including sports clubs and town halls. Eligible participants can receive a 30% discount on the cost of a home battery system.
Funded directly by the federal government, the initiative will be implemented through the Small-scale Renewable Energy Scheme—the same program that has successfully subsidized solar panel installations since 2011 and helped drive Australia’s early adoption of rooftop solar.
When Does the Battery Discount Start?
While the national battery subsidy officially begins on July 1, at the start of the new financial year, the scheme has been structured so that households can purchase and install batteries now. As long as the battery system is switched on after July 1, it will be eligible for the rebate.
This proactive approach aims to avoid delays seen in previous state schemes—like those in New South Wales and Western Australia—where long gaps between announcements and implementation led to uncertainty and postponed purchases.
Better still, the federal subsidy can be combined with existing state-level rebates, allowing even greater savings for households in participating states.
Why Invest in a Home Battery?
Australia leads the world in rooftop solar adoption—with around one in two homes in Queensland and Western Australia now fitted with solar panels.
This widespread uptake has created a surplus of solar energy during the middle of the day, often exceeding household demand. As a result, many solar homes export excess energy back to the grid.
However, when the sun goes down and people return home, energy use spikes—right when solar production drops. This creates pressure on the electricity grid during peak evening hours.
A home battery allows solar households to store excess energy generated during the day and use it later in the evening. This not only cuts reliance on the grid during peak times but also helps lower electricity bills and supports a more stable, renewable-powered energy system.
How Big Should Your Home Battery Be?
While energy usage varies from household to household, recent analysis by the Smart Energy Council suggests that the battery size needed to significantly reduce power bills is smaller—and more affordable—than many people expect.
Their findings show that over 90% of Australian households could effectively cover their peak evening energy use with a battery as small as 6 to 7 kilowatt-hours.
That’s notably smaller than many of the most popular batteries on the market today—such as the commonly installed 13 kWh models.
Choosing the right battery depends on your budget, energy habits, and long-term goals—but it doesn’t always mean going big to start saving.
How Much Does a Home Battery Cost?
Popular home battery systems in Australia—such as those from Tesla and BYD—typically offer around 13 kilowatt-hours of storage and cost between $12,000 and $14,000 installed, before any government subsidies.
Under the new federal subsidy program, the average household could save around $4,000 on a standard battery installation. And in states offering additional incentives, total savings could be even higher.
However, whether a battery is a smart financial move depends on your home’s specific energy usage and solar generation. It’s important to assess your situation before making the investment.
The good news? Battery prices are trending downward. Home energy storage uses the same core technology as electric vehicle batteries, and as EV adoption grows, it’s helping to drive down costs across the board.
What If You Can’t Get a Home Battery?
While the new subsidy is a great opportunity for homeowners who can afford a battery, many Australians—especially renters and low-income households—are still being left out.
This has sparked concerns around equity. The Greens, for example, campaigned for a dedicated solar and battery program targeting these underserved groups.
However, there are alternatives. According to government advisor Ms Shaw, investments made during the last election have funded a number of community batteries, which allow broader participation:
“Community batteries are vital for energy equity,” she explains. “You don’t need to own a home to benefit from them.”
In addition to community storage, Australia has also seen major investment in large-scale grid batteries. Ms Shaw points out that while those projects have matured and no longer need government subsidies, household batteries were the missing link—and now they’re receiving the necessary support.
Even if you don’t own a battery, there’s still a broader benefit. As more homes store and use their own solar energy, they reduce demand on the grid during peak times—like early evenings—helping to lower electricity prices across the board.
In short: more batteries anywhere means savings for everyone.
