The Clean Energy Regulator (CER) engages consultants to analyse and model aspects of the Small-scale Renewable Energy Scheme (SRES), including:
- reviewing the market for small-scale technology certificates (STCs)
- estimating the number of STCs to be created in a relevant calendar year
- identifying key factors affecting the type, number and size of small-scale systems installed
- projecting the likely composition of renewable energy sources under the SRES.
CER does not guarantee or accept any legal liability arising from or connected to, the accuracy, reliability, currency or completeness of any material contained in these reports.
The material in the reports does not necessarily reflect the views of the agency or indicate its commitment to a particular outcome or course of action. While the agency accepts the studies as opinions of these consultants, it recognises that there are many other opinions on the future uptake of small-scale renewables. The reports reflect STC numbers based on the scheme at the time.
Current year modelling reports
Modelling for the 2023 STP and the 2024-25 non-binding STP
Two consultants were engaged to estimate the number of STCs likely to be created in 2023, 2024 and 2025. The average of these estimates for each year in question is used to calculate the 2023 small-scale technology percentage (STP) and the 2024 and 2025 non-binding STPs.
The reports are based on data the CER gave to the consultants, current as at 1 November 2022.
Interim modelling for the 2023 STP
Previous year modelling reports
The CER has engaged a number of consultants in previous years to provide forward estimates of the number of STCs likely to be created in those years.
