What battery schemes can you use in New South Wales?
| Scheme | Status | What it pays |
|---|---|---|
| Cheaper Home Batteries Program (federal) | Open to 31 December 2030 | The first 14 kWh earn $272 each; above that the rate falls to 60%, then 15% |
| NSW virtual power plant (VPP) incentive | Open | Upfront payment for connecting a battery to a VPP; amount set by the VPP provider, rises with capacity up to 28 kWh |
What discount applies to batteries installed in 2026?
The federal discount cuts installation costs by roughly 30%. The amount depends on your battery's size, when it is installed and the price paid for the certificates that fund the discount. The Clean Energy Regulator decides the rate, which drops on 1 January 2027 and once more on 1 July 2027.
These discount estimates use $40 per certificate; your quote may use a lower certificate price. The final column shows typical installed prices after the federal discount.
| Battery size | May–Dec 2026 discount | Jan–Jun 2027 discount | Jul–Dec 2027 discount | Price after discount |
|---|---|---|---|---|
| 10 kWh | $2,720 off | $2,280 off | $2,080 off | about $7,000–$11,000 |
| 13.5 kWh | $3,640 off | $3,040 off | $2,800 off | about $9,800–$13,800 |
| 20 kWh | $4,760 off | $4,000 off | $3,640 off | about $14,000–$19,000 |
| 30 kWh | $6,160 off | $5,160 off | $4,720 off | about $18,000–$22,000 |
Bigger batteries still get a bigger discount, but each extra kWh counts for less once you go past 14 kWh, and nothing past 50 kWh counts at all. That is why a 30 kWh battery doesn't get double what a 15 kWh one does.
NSW VPP incentive
A VPP, short for virtual power plant, is a network of household batteries that an energy company can call on at busy times, and in exchange you receive a payment or credit. Joining a participating VPP with a battery above 2 kWh and up to 50 kWh can also get you a NSW Government incentive, paid through your provider on top of its own offers.
There is no one set figure, because the provider decides the amount and it grows with the capacity you share, capped at 28 kWh. As a rough guide, it works out to around $36 per kWh. That means roughly $360 for a 10 kWh battery and roughly $486 for 13.5 kWh. Payments can arrive as a lump sum, spread over instalments, or as a credit on your electricity bill.
To claim it, you join a VPP: sign the provider's contract and nomination form, then complete its online form after the cooling-off period. Joining is your choice. To get the federal discount, your battery only needs to be able to join a VPP, so you can decide later.
NSW battery eligibility rules
NSW's own discount for battery installations closed on 1 July 2025, so the federal Cheaper Home Batteries Program is now the source of any discount on your quote. A battery qualifies if it:
- sits between 5 and 100 kWh in size and appears on the approved battery list kept by the Clean Energy Council
- goes in alongside solar panels, either new or existing, since a battery charged only from the grid earns nothing
- is put in by an installer accredited with Solar Accreditation Australia plus a battery endorsement
- is the sole battery claimed at that address, and is installed from 1 July 2025 onwards
You don't need to apply to anyone. The discount is handed out as certificates, which your installer generates and sells for up to $40 apiece. You sign a form handing over that right, and they subtract the value from your quote before you pay anything. Each installer sets its own price and its own discount, so a few quotes side by side show you who really gives the best deal.
Send the short form to compare local battery quotes with the federal discount already deducted.
Common questions about NSW's battery rebate
Will the battery rebate still exist in 2028 and beyond?
Yes. The federal scheme runs until 31 December 2030, though the rate keeps falling every 6 months. For a 10 kWh battery, expect $1,840 during the first six months of 2028, $1,440 during the first six months of 2029, and $840 across the last six months of 2030.
Is it possible to claim the NSW VPP incentive twice?
No. The payment is made once for each electricity meter, batteries in apartment blocks miss out, and anyone who claimed it from 1 November 2024 through to 30 June 2025 cannot claim it a second time.
Do new solar panels also attract a rebate?
Yes. New solar panels qualify for a separate discount. A 6.6 kW system in Sydney brings in roughly $1,800 when installed in 2026, and a 10 kW setup roughly $2,760.
Is the federal battery rebate identical in NSW and other states?
Yes. The federal discount matches across every state. What differs between states is the extra top-up. Western Australia chips in $1,300 or $3,800, NSW offers only the VPP incentive, and most other states currently add nothing.
