What is an LGC?

An LGC represents one megawatt hour (MWh) of net renewable energy generated by a solar PV system of more than 100kW capacity, or which generates over 250MWh each year. The generation can include anything which is consumed on the premises or exported to a distribution or transmission network.


How are LGCs different to STCs?


While similar in many respects, there are a two key differences between the two certificate types:

  1. LGCs are created based on data readings of the actual renewable power generated by the power station and can be created on a yearly, quarterly or monthly basis throughout the lifetime of the station until the RET ends in 2030.

  2. STCs are created based on the expected renewable energy generation of a small generation unit until the RET ends in 2030.


What is required to get a power-station accredited to create LGCs?


Once the power station owner has nominated Green Energy Trading as the registered person responsible to create the LGCs, we will apply to the Clean Energy Regulator (CER) to accredit the system as a power station under the Renewable Energy Target (RET). Data required to complete this registration includes:

  1. Basic station profile

  2. Details of the metering system, electricity transmission and use

  3. Certificate calculation methodology (taking into account energy losses, auxiliary use, etc.)

  4. Details of project approvals

  5. Generation projections
