Certificates

Eligible renewable energy sources are entitled to create certificates based on the amount of electricity they produce or displace. These certificates can be created in the REC Registry and sold to buyers. This process creates an incentive for the growth in large-scale and small-scale renewable energy systems. From 1 January 2011 Renewable Energy Certificates (RECs) were reclassified as large-scale generation certificates (LGCs) and small-scale technology certificates (STCs).

Large-scale Generation Certificates (LGCs) 

LGCs are created in the online REC Registry by renewable energy power stations. One LGC is equivalent to 1 MWh (megawatt hour) of eligible renewable electricity generated above the power station's baseline.

Small-scale Technology Certificates (STCs) 

STCs are created in the online REC Registry for correctly installed eligible solar water heaters, heat pumps, and small-scale solar panels, wind and hydro systems. One STC is equivalent to 1MWh (megawatt hour) of:

• renewable electricity generated by the solar panel, small-scale wind or hydro system (unless the Solar Credits multiplier applies); or
• electricity displaced by the installation of a solar water heater or heat pump.
