From 1 May 2026, the Federal Government is introducing major changes to how battery rebates are calculated under the Small‑scale Renewable Energy Scheme (STCs). Instead of a single rebate value for all battery sizes, the system will shift to a tiered structure and twice‑yearly reductions, meaning the value of the rebate will decline faster than before.
What’s changing
- More frequent reductions: STC values will now drop in value every six months, accelerating the phase‑out of financial support.
- New tiered rebate system:
- 0–14 kWh → 100% STC rate
- 14–28 kWh → 60% STC rate
- 28–50 kWh → 15% STC rate
- Larger batteries get less support: Only the first 14 kWh receives the full rebate. Any capacity above that is discounted heavily.
- Applies to all installations from 1 May 2026 onward: Systems installed before this date still receive the current, higher rebate structure.
What it means for customers
- Installing before May 2026 could lock in a significantly higher rebate.
- Battery sizing becomes more strategic—oversizing may no longer deliver good value.
- Rebate value will vary based on installation date, battery size, and the fluctuating STC market price.
- Customers waiting too long may pay more, as the rebate will shrink twice a year until 2030.
The upcoming rebate changes make early action the smartest move. With reductions happening twice a year and larger batteries receiving less support, customers who install before May 2026 will secure the strongest financial benefit. Acting now protects them from shrinking incentives and ensures they get maximum value from their battery investment.
