Home battery rebate Australia: what you actually get
The federal rebate takes roughly 30% off a home battery, and your installer applies it at the point of sale. Above 14kWh the rate tapers, which changes what size actually makes sense. Here it is in plain terms, with worked numbers.

What the rebate actually is
It is called the Cheaper Home Batteries Program, and it is federal, so it applies across Australia. It discounts roughly 30% of the upfront cost of an eligible battery, for systems between 5kWh and 100kWh.
You do not claim it back yourself. The discount runs through small-scale technology certificates (STCs), which your accredited installer handles and applies straight to the quote. If a quote does not show it itemised, that is a fair thing to push back on.
How much it is worth
From 1 May 2026 it works out at roughly $252 per usable kWh for most standard home batteries. That comes from 6.8 STCs per usable kWh at about $37 per certificate after typical transaction and admin costs.
Because the STC price moves with the market, treat $252 as a close guide rather than a fixed number. Your installer quotes the real figure on the day.
The 14kWh taper
From 1 May 2026 the rate no longer applies flat across the whole battery. It steps down as capacity grows, which means the rebate does not scale with the size of the system.
| Capacity band | Rate applied | Roughly per kWh |
|---|---|---|
| First 14kWh | 100% of the rate | ~$252 |
| 14kWh to 28kWh | 60% of the rate | ~$151 |
| 28kWh to 50kWh | 15% of the rate | ~$38 |
Per-kWh figures are derived from the ~$252 base rate and rounded. Indicative only.
Worked examples
Using the ~$252 base rate and the taper, here is roughly what different sizes attract. These are indicative, not quotes.
| Battery size | Approx. rebate | How it stacks up |
|---|---|---|
| 10kWh | ~$2,520 | Full rate on every kWh |
| 14kWh | ~$3,528 | The last size at the full rate |
| 20kWh | ~$4,435 | First 14kWh full, next 6kWh at 60% |
| 28kWh | ~$5,645 | Everything above 14kWh at 60% |
Going from 14kWh to 20kWh adds 6kWh of battery but only about $900 of rebate, because those kWh earn the reduced rate. Size for your evening usage rather than the subsidy.
State incentives on top
The federal discount is national, and some states add their own on top. NSW, for example, offers $1,500 for joining a Virtual Power Plant, where your battery helps support the grid at peak times in exchange for a payment.
What you can actually claim depends on your state, your battery, your retailer and the VPP terms, so treat this as a question for your installer rather than something to assume.
Is it worth it after the rebate?
It depends on your setup, and any payback figure quoted from a web page is guesswork. The rebate cuts the upfront cost, which shortens payback, but it cannot create savings your usage pattern does not support.
What matters is whether you use a meaningful amount of power in expensive peak periods, and whether you have solar generating cheap energy to store. If both are true the numbers tend to work. If your usage is low, or you are out all evening, a battery has less to do.
Ask any installer for a projection built on your real bills, and sanity check it yourself.

Frequently asked questions
How much is the home battery rebate in Australia in 2026?+
The federal Cheaper Home Batteries Program discounts roughly 30% of the upfront cost of an eligible battery. From 1 May 2026 it works out at about $252 per usable kWh for most standard home batteries, based on 6.8 small-scale technology certificates per usable kWh at roughly $37 per certificate after typical costs. The exact figure moves with the STC market price, so treat it as a close guide rather than a fixed number.
Do I claim the battery rebate myself?+
No. The discount is applied at the point of sale by your accredited installer, who handles the certificates. You should see it come off the quote rather than paying full price and claiming money back later. If a quote does not clearly show the rebate applied, ask for it to be itemised.
Does the rebate get bigger if I buy a bigger battery?+
Not proportionally. From 1 May 2026 the rate tapers with capacity: the full rate applies to the first 14kWh, then 60% of the rate from 14kWh to 28kWh, then only 15% from 28kWh to 50kWh. So each extra kWh past 14kWh earns a smaller discount, and oversizing has real diminishing returns.
What size battery is eligible for the rebate?+
The program covers small-scale battery systems from 5kWh up to 100kWh. Rebate value is calculated on usable capacity, and the taper above 14kWh means the strongest value per kWh sits in the smaller end of that range for a typical home.
Are there state rebates as well as the federal one?+
Often, yes, and they can stack. The federal discount applies nationally, and some states add their own incentive on top. NSW, for example, offers $1,500 for joining a Virtual Power Plant (VPP). What you can claim depends on your state, your battery, your retailer and the VPP terms, so confirm what applies at your address when you get a quote.
Do I need solar panels to claim the battery rebate?+
A battery is normally installed alongside solar, and that is where the economics are strongest, since you store what you generate rather than exporting it cheaply. Requirements and the sensible setup vary by installer and state, so confirm eligibility for your specific situation before committing.
Is a home battery worth it after the rebate?+
It depends on your usage, your tariff, whether you have solar and whether you join a VPP, so no page can promise you a payback figure. The rebate materially cuts the upfront cost, which shortens payback, but what matters is whether you actually consume enough power in expensive peak periods for a battery to shift. Ask any installer for a projection built on your real bills.
Where can I get a quote with the rebate applied?+
Any accredited installer applies the federal discount at the point of sale. Through Refer Labs, Apollo Energy Group also takes an exclusive $500 off your quote on top of the rebate, with no code to enter. The form takes under 30 seconds and carries no obligation.
