The Clean Energy Regulator 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.
The Clean Energy Regulator 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 Clean Energy Regulator or indicate its commitment to a particular outcome or course of action. While the Clean Energy Regulator 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
Three consultants were engaged to estimate the number of STCs likely to be created in 2021, 2022 and 2023. The average of these estimates for each year in question is used to calculate the 2021 small-scale technology percentage (STP) and the 2022 and 2023 non-binding STPs.
The reports are based on data the Clean Energy Regulator gave to the consultants, current at 31 December 2020.
Interim modelling 2020
In July 2020, we engaged three consultants to model small-scale (0-100 kilowatts) and mid-scale (100 kilowatts to 30 megawatts) solar PV uptake over the five years from 2020 to 2024. This modelling is to help understand the PV market.
This modelling does not inform the STP and should be used as a guide only.
