Small-scale Technology Certificates (STCs) are part of the Federal Government's Small-scale Renewable Energy Scheme (SRES). The STCs are a financial incentive for owners of new and existing homes to install small-scale installations such as solar hot water, heat pumps and solar electricity systems. Each STC is equivalent to one megawatt hour of electricity generated or displaced by renewable energy. The number of STCs received per installation is dependent on the size and type of system as well as the geographic location of the installation.
The STCs are registered with the Clean Energy Regulator by a registered agent. Once the STC goes through the registration process, liable entities, usually the large electricity retailers are required to purchase a certain number of STCs each quarter to comply with the liability placed on them by the government to contribute to the installation of renewable energy in Australia.
An STC is equivalent to one megawatt hour of electricity generated or displaced by renewable energy.
Large-scale Generation Certificates (LGCs) are a part of a Federal Government scheme called the Large-scale Renewable Energy Target. LGCs work as an incentive to encourage the establishment of large renewable energy stations such as, wind and solar farms or hydro-electric power stations.
