Renewable Energy Target (RET)

Small-scale Renewable Energy Scheme (SRES)

The Small-scale Renewable Energy Scheme creates a financial incentive for owners to install eligible small-scale installations such as solar water heaters, heat pumps, solar panel systems, small-scale wind systems, or small-scale hydro systems. It does this by legislating demand for Small-scale Technology Certificates (STCs). STCs are created for these installations according to the amount of electricity they produce or displace. RET liable entities have a legal requirement to buy STCs and surrender them on an quarterly basis.

Large-scale Renewable Energy Target (LRET)

The Large-scale Renewable Energy Target creates a financial incentive for the establishment and growth of renewable energy power stations, such as wind and solar farms, or hydro-electric power stations.

It does this by legislating demand for Large-scale Generation Certificates (LGCs). These LGCs are created based on the amount of eligible renewable electricity produced by the power stations. LGCs can be sold or traded to liable to entities, in addition to the power station’s sale of electricity to the grid. RET Liable entities have a legal obligation to buy LGCs and surrender them to the Clean Energy Regulator on an annual basis.

Solar Credits

Small-Scale Technology Certificates (STC)

Solar Credits is a mechanism which increases the number of small-scale technology certificates (STCs) able to be created for eligible installations of small-scale solar panel, wind and hydro systems.

Solar Credits are provided in the form of additional tradable certificates called small-scale technology certificates (STCs) for eligible small-scale renewable energy systems including solar photovoltaic (PV) systems.

While it is possible for owners of renewable energy systems to create and sell the STCs themselves, in practice, installers of these systems usually offer a discount on the price of an installation, or a cash payment, in return for the right to create the STCs. Householders considering installing small-scale renewable energy systems are encouraged to shop around for the best deal.

These costs are based on the SA Power network in Adelaide but prices may vary depending on your circumstances. This comparison assumes a general energy usage of 4000kWh/year for a residential customer on Energy Locals Time of Use Tariff – (TOU – Peak, Off-Peak & Solar Sponge).

The reference price is set by the Australian Energy Regulator (AER) for a financial year in relation to electricity supply to residential customers in the distribution region and is based on an assumed annual usage amount. Any difference between the reference price and the unconditional price of a plan is expressed as a percentage more or less than the reference price. The terms of any conditional discounts are shown, along with any further difference between the reference price and the discount applied if a condition is met, expressed as a percentage more or less than the reference price.
