The proposal would amend the Renewable Energy (Electricity) Act 2000 (the Act) to add home batteries as an eligible technology to earn Small-scale Technology Certificates (STCs) through the Small-scale Renewable Energy Scheme from 1 July 2023.

In addition, the proposal would extend the “deeming rate” – the period for which a technology can earn STCs – out to a set period of 15 years for home batteries; then, from 2025, the time between installation and when the scheme ends (2040).

The changes to deeming rates only apply to home batteries, and no other changes to the Act are proposed.
