Quick snapshot
Adelaide homeowners can stack three battery rebates in 2026 — the federal Cheaper Home Batteries program, the SA REPS VPP rebate and (within the City of Adelaide) a council rebate — to take $4,000–$6,700+ off the cost of a home battery.
The federal Cheaper Home Batteries program
Launched on 1 July 2025, this national program discounts the cost of a new home battery through the Small-scale Renewable Energy Scheme. Your installer applies it upfront using Small-scale Technology Certificates (STCs), so there is no separate application.
The rebate is based on your battery's usable capacity and the STC value at the time it's switched on — and that value steps down every six months.
| Battery size | Approx. rebate, Jan–Apr 2026 | Approx. rebate, May 2026+ |
|---|---|---|
| 10 kWh | ~$3,360 | ~$2,720 |
| 13.5 kWh (e.g. Powerwall 3) | ~$4,536 | ~$3,672 |
| 16 kWh | ~$5,376 | ~$4,352 |
Most Adelaide homes use 15–25 kWh a day, so a 10–13.5 kWh battery is usually the sweet spot — and it sits in the full-rebate tier.
Who qualifies in South Australia
Property – grid-connected and in Australia; owners and renters (with landlord permission); houses, townhouses and apartments.
Battery – 5–100 kWh usable, VPP-capable (you don't have to join one for the federal rebate), brand new, and on the Clean Energy Council approved list.
Installation – by a CEC-accredited installer, commissioned on or after 1 July 2025, to Australian Standards.
There is no income test for the federal program — every eligible household can access it.
Stacking the rebates
The real saving comes from combining programs. Worked example on a Tesla Powerwall 3:
| Source | Amount | When it applies |
|---|---|---|
| Federal Cheaper Home Batteries (STC) | ~$3,672 | Off the quote, upfront |
| SA REPS VPP rebate (priority group) | up to $1,030 | After you join a VPP |
| City of Adelaide battery rebate | up to $2,000 | Council application (if eligible) |
| Combined | $4,700–$6,700+ |
The council rebate only applies inside the City of Adelaide boundary, but the federal and REPS rebates are available across greater Adelaide.
Which batteries qualify
We install a range of VPP-capable, rebate-eligible batteries:
- Tesla Powerwall 3 – 13.5 kWh, built-in inverter and 24/7 backup.
- Sungrow SBR – modular 9.6–25.6 kWh with LFP chemistry.
- Alpha ESS – budget-friendly and VPP-compatible.
- Sigenergy SigenStor – scalable all-in-one with EV-charging capability.
- Neovolt – 9.6 kWh LiFePO4, cost-effective for smaller homes.
How to claim, step by step
- Get a quote from an accredited installer (we handle the STC claim) with the full price and the discount shown separately.
- Choose your battery and book the install, timed to lock in the current STC value.
- We claim the STCs on your behalf after commissioning — the discount is already in your price.
- Join an eligible VPP (such as AGL, Amber, ENGIE or Origin) to unlock the REPS rebate.
- Submit the REPS application with proof of address, VPP connection and battery details — processing takes up to 60 days.
- Claim the City of Adelaide rebate (up to $2,000) if you're inside the council boundary.
