Historical large-scale renewable energy supply data

There are 8 co-fired accredited power stations not reported as accredited capacity under the Renewable Energy Target. These power stations have the potential to generate electricity from biomass, but the renewable capacity represents a very small component of total capacity. Many of these power stations no longer create LGCs. The capacity of these power stations appears as ‘zero’ in the dataset.

These are power stations with more than one fuel source. There are 2 types of hybrid power stations:

1. Existing accredited power stations can add additional fuel sources retrospectively. These expansions have an effective date from when LGCs for the additional fuel sources can be created.
2. Power stations with co-located fuel sources may also apply for accreditation as a hybrid power station. These hybrid power stations can create LGCs for all accredited fuel sources from the accreditation start date.

The renewable energy fuel source that contributes the majority of the total accredited capacity is classified and reported as the primary fuel source of a power station. Where an expansion includes an additional fuel source, the primary fuel source is the original accredited fuel source.

Small-scale solar photovoltaic systems that received small-scale technology certificates under the Small-scale Renewable Energy Scheme may be eligible under the LRET if added capacity means the power station exceeds 100 kilowatts. The expanded capacity that did not receive small-scale technology certificates may be eligible for LGCs. The original system is not eligible for additional entitlements under the Renewable Energy Target.

The total accredited capacity for these power stations may or may not include the capacity of the original system. For power stations accredited from August 2018, if the accredited capacity does include the capacity of the original system, the power station name will have 'w SGU' included in their name. Power stations accredited before August 2018 that have a Small-scale Renewable Energy Scheme component in their total accredited capacity may not be identified in the dataset.

Power stations generating electricity prior to 1 January 1997 are accredited with a renewable energy power baseline. Only renewable energy generation above this baseline is eligible for LGCs. Baselines may vary year on year. The data reflects the 2023 calendar year baseline for each power station. Data on historical baselines is available on the REC Registry public register.

Power stations may be suspended temporarily or permanently, to ensure the integrity of the LRET is maintained. A power station is not eligible for LGCs for the period of time they are suspended. A power station that is suspended is still accredited and the capacity is reported under the Renewable Energy Target.
