Home Battery Rebate in Adelaide (2026)

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.

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.

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.

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.

1. Get a quote from an accredited installer (we handle the STC claim) with the full price and the discount shown separately.
2. Choose your battery and book the install, timed to lock in the current STC value.
3. We claim the STCs on your behalf after commissioning — the discount is already in your price.
4. Join an eligible VPP (such as AGL, Amber, ENGIE or Origin) to unlock the REPS rebate.
5. Submit the REPS application with proof of address, VPP connection and battery details — processing takes up to 60 days.
6. Claim the City of Adelaide rebate (up to $2,000) if you're inside the council boundary.

We install and handle battery rebates across Adelaide, including St Agnes, Salisbury, Norwood, Unley, Prospect, Modbury, Golden Grove, Mawson Lakes, Glenelg, Marion, Tea Tree Gully and the City of Adelaide.
