How the rebate works

Three steps from battery quote to discount

1

Your battery earns certificates

When an eligible battery is installed, the scheme allows a set number of Small-scale Technology Certificates (STCs) to be created. The count depends on your battery's usable capacity and the current scheme factor. In 2026 the rate is 6.8 certificates per usable kWh for the first 14 kWh of capacity.

2

A registered agent discounts those certificates at point of sale

You assign the right to create those certificates to a registered agent (a company approved by the Clean Energy Regulator). The agent creates the certificates and gives your installer an upfront discount equal to the certificate value. Your invoice is lower by that amount. You do not receive a cheque; the saving appears as a line-item discount on your battery quote.

3

Your installer handles the paperwork

Your CEC-accredited installer submits the installation details, serial numbers, and your signed STC assignment form to the registered agent. The agent lodges the certificates with the government's REC Registry. You sign one form; your installer does the rest. State scheme incentives (where available) follow a similar process through your installer or a VPP provider.

Common questions

Frequently asked questions

No. This is an independent estimate tool, not affiliated with the Australian Government, the Department of Climate Change, Energy, the Environment and Water (DCCEEW), or the Clean Energy Regulator (CER). For the official scheme rules, see dcceew.gov.au and the REC Registry. This calculator uses published scheme factors but scheme rules can change, so always confirm with your installer before committing.
To be eligible your battery must: (a) have at least 5 kWh of nominal capacity; (b) be on the Clean Energy Council's approved battery product list; (c) be capable of connecting to a Virtual Power Plant (though VPP participation is not compulsory); (d) be installed by a CEC-accredited installer; and (e) be at a grid-connected property. The rebate applies to the first 50 kWh of usable capacity per property. You can only claim once per eligible battery at a given premises.
It depends on your state. As of June 2026: WA has an active Residential Battery Scheme (Synergy customers up to $1,300, Horizon Power customers up to $3,800), requiring VPP enrolment. NSW has the Peak Demand Reduction Scheme, which can add $500 to $720 net for VPP-connected batteries. ACT offers an interest-free loan of up to $15,000 (not an upfront discount). QLD, VIC, SA, TAS and NT do not currently have active state battery rebate schemes; households in those states access the federal CHBP only.
Batteries between 5 kWh and 100 kWh in nominal capacity are eligible. The rebate is calculated on usable capacity (not nominal), up to a maximum of 50 kWh usable per installation. The rebate is tiered: the first 14 kWh of usable capacity earns the full rate; the next 14 kWh (up to 28 kWh usable) earns 60% of the rate; and usable capacity from 28 kWh to 50 kWh earns 15%. Most popular home batteries are in the 10 to 15 kWh usable range, which means they receive the full Tier 1 rate.
Very little. You will need to sign an STC assignment form, which your installer provides. This transfers the right to create the certificates to the registered agent so the discount can be applied to your invoice. For state schemes like WA, you may also need to enrol in a VPP through your chosen provider. Your CEC-accredited installer manages all other paperwork: the STC lodgement, DNSP notification, and compliance certificates required under your state's electrical safety rules.
