How much is the battery rebate?
The federal discount comes from the national government. How much you get depends on the size of your battery and when it is installed. Installed by 31 December 2026, a 10 kWh battery costs about $2,720 less, and a Tesla Powerwall 3 (a popular 13.5 kWh battery) about $3,640 less.
A bigger battery still gets more money off, just not as much more: a 20 kWh battery gets about $4,760.
Twice a year, in January and July, the discount gets a little smaller, until the program closes at the end of 2030. The Clean Energy Regulator, the government body that runs it, sets the amounts.
What your state adds on top
Western Australia gives up to $1,300 if Synergy supplies your power, or up to $3,800 if Horizon Power does. These are the two power companies owned by the Western Australian government. To get it, you must join a virtual power plant (VPP). A VPP is many home batteries linked together, so the power company can use them when lots of people need power. You usually get money off your power bill, or a payment, for it.
New South Wales pays extra if you join a VPP. The money comes through the VPP company you choose, and that company decides how much. The ACT (Australian Capital Territory) doesn't give a rebate. Instead it lends up to $20,000, which you pay back with 3% interest a year. Victoria, Queensland, South Australia, Tasmania and the Northern Territory don't add anything right now.
Who qualifies for the battery rebate?
- The battery holds between 5 and 100 kWh and is on the approved list of the Clean Energy Council, the industry body that checks batteries.
- It is installed with solar panels, new ones or ones already on your roof.
- The installer is approved by Solar Accreditation Australia, the body that approves solar and battery installers.
- Each home can get the discount for one battery only.

Battery rebate: your common questions
Is there a form to fill in for the battery rebate?
No. Your installer claims it for you. You sign a form that lets them, and they take the discount off your quote.
Is the battery rebate ending?
No. It stays open until the end of 2030. The amounts drop a little every January and July, so a battery installed sooner gets more.
I already have solar. Can I still get the battery rebate?
Yes. Panels that are already on your roof count. The battery just has to be connected to solar, old or new. A home with no solar panels can't get the discount.
Do I need to join a virtual power plant?
No, not for the federal discount. Your battery only needs to be the kind that could join one. Western Australia is different: you get the state rebate only when you sign up to a VPP run by Synergy or Horizon Power.
