Changes to the deeming period from 1 January 2024

Source: The Clean Energy Regulator

The Clean Energy Regulator would like to remind all registered agents and persons about the upcoming changes to the deeming period under the Small-scale Renewable Energy Scheme (SRES).

The deeming period for solar PV, solar water heaters and air sourced heat pumps decreases by one year for all systems installed after 1 January 2024. The deeming period for systems installed in 2024 is a maximum of 7 years – one year less than systems installed in 2023.

This change will reduce the number of small-scale technology certificates (STCs) that solar PV, solar water heater and air sourced heat pump systems are eligible for. We have updated the small generation unit STC calculator and the solar water heater STC calculator to reflect the upcoming deeming period decrease.

We closely monitor all installation dates for STC applications to ensure the correct deeming period is applied. It is important to remember that the provision of false and/or misleading information is an offence under the Renewable Energy (Electricity) Act 2000. STCs which have been improperly created will be failed and subject to enforcement and/or administrative action.

Yours sincerely
