Small scale technology certificate projections: 2024-2028

Client: Clean Energy Regulator


The Clean Energy Regulator (CER) administers the Small-scale Renewable Energy Scheme (SRES) that creates financial incentives for investment in eligible small-scale renewable energy systems. Eligible small-scale renewable energy systems include solar photovoltaic (solar PV), solar water heater (SWH), air source heat pump (ASHP) and other small generation units (SGUs). SGUs are defined as those systems with capacity of no more than 100kW. The number of small-scale technology certificates (STCs) required to be surrendered by liable entities is set each year by the small-scale technology percentage (STP).

The CER has engaged ACIL Allen to undertake projections of:

  • the number of small-scale installations (up to 100 kW)
  • the capacity of small-scale installations (up to 100 kW)
  • small-scale technology certificate (STC) creation.

The projections cover calendar years 2024 to 2028 and the following technology types:

  • small-scale solar PV
  • solar water heaters (SWHs)
  • air source heat pump (ASHPs).

The projections are provided for commercial and residential installations for each state and territory in Australia.
