The SRES creates a financial incentive for individuals, households and small businesses to install eligible small-scale renewable energy systems. Examples include:
Each megawatt hour of renewable energy generated/or displaced by the system is awarded one small-scale technology certificate (STC). STCs are calculated from installation date until the end of 2030 when the scheme ends.
System owners typically assign the right to an agent to sell STCs on their behalf to receive an upfront lower purchase price. System owners can alternatively claim and sell the STCs themselves. Visit
information for consumers for more information on this process.
Liable entities also have a legal obligation to buy and
surrender STCs to the Clean Energy Regulator on a quarterly basis.
The number of STCs required to be submitted by electricity retailers is set each year by the
small-scale technology percentage.
