SA Battery FAQs
helpWhat is the REPS VPP incentive in South Australia?
The Retailer Energy Productivity Scheme (REPS) VPP incentive offers up to $2,050 when you install a battery and join an approved Virtual Power Plant program in South Australia. The VPP operator applies the incentive as a discount on your battery installation. You also earn ongoing credits by allowing the VPP to dispatch your stored energy during peak demand.
helpIs the SA Home Battery Scheme still available in 2026?
No. The SA Home Battery Scheme officially closed in December 2025 after all funding was allocated. However, South Australians can still access the REPS VPP incentive (up to $2,050), the federal Cheaper Home Batteries rebate (~$3,300 for 10kWh), and the City of Adelaide bonus ($1,000) — totalling $5,000-$6,000+ in savings.
helpHow do I get the $1,000 City of Adelaide battery bonus?
The City of Adelaide offers a $1,000 bonus for residents in postcodes 5000 and 5006 who install an eligible home battery system. You must be a ratepayer in the City of Adelaide council area.

helpWhy are batteries especially good value in South Australia?
South Australia has the highest average electricity prices in Australia, often exceeding 40c/kWh on peak tariffs. This means batteries deliver the biggest dollar savings through self-consumption and time-of-use arbitrage. Combined with generous rebates and strong solar irradiance, SA households can achieve payback in as little as 4-6 years.
helpHow much can I earn from a VPP in South Australia?
SA VPP participants typically earn $300-$1,500+ per year in credits depending on the program and battery size. You also receive a $150 annual bill credit for VPP participation. During extreme demand events, VPP earnings can spike significantly. SA's volatile wholesale market makes it one of the most profitable states for VPP participation.
helpWhat does a 10kWh battery cost in SA after all rebates?
A 10kWh battery in South Australia costs approximately $11,000 installed before incentives. After the REPS VPP incentive ($2,050) and federal rebate (~$3,300), your out-of-pocket cost is around $5,650. Adelaide residents in postcodes 5000/5006 can reduce this further to ~$4,650 with the City of Adelaide bonus.
helpCan I stack the REPS VPP incentive with the federal battery rebate?
Yes. The REPS VPP incentive and the federal Cheaper Home Batteries rebate are fully stackable. You can claim both on the same battery installation. If you're in the City of Adelaide, you can also stack the $1,000 council bonus on top, giving you three separate incentives on one battery.
