Figures are indicative, based on an STC spot price of AUD $38.00 (as at 24 April 2026), deeming factors published by the Clean Energy Regulator (8.4 to 30 April; 6.8 from 1 May), and the 14 kWh un-tapered band announced in the 1 May 2026 program changes. Installer admin fees (typically 2–5% of STC gross) reduce the pass-through to your quote. For batteries larger than 14 kWh, the taper on capacity above 14 kWh is still being finalised by CER — figures in that row will be updated when bands are published. See methodology.
State-level incentives in ACT
ACT households can stack the following on top of the federal CHBP. Each scheme has its own eligibility rules (system size, installer accreditation, VPP enrolment) — confirm eligibility before signing a quote.
- Stacks with federal CHBP
Sustainable Household Scheme (interest-free loan)
Interest-free loan, up to $15,000
ACT households can access an interest-free loan of up to $15,000 covering eligible energy upgrades, including batteries. Stacks with the federal CHBP — the loan funds the post-rebate balance.
