Platts to launch Australian Large-scale Generation price assessments, March 30

Platts, part of S&P Global Energy, will launch Australia Large-scale Generation Certificate (LGC) price assessments, effective March 30, 2026.

Platts first proposed launching the assessment on Feb. 9, in a subscriber note available here.

The launch responds to market feedback calling for greater price transparency in the Australian LGC market. The assessments will also complement Platts' existing offerings in the Australian energy transition and emissions reduction space, including the Platts Australian Carbon Credit Unit assessment suite.

The Australian LGC assessments will reflect spot and forward certificate deliveries, with a minimum volume size of 1 GWh for Spot, Current-Year (Forward), and Year +1 to Year +3.

These assessments will roll to the next vintages on Feb. 15 of each year, following the LGC surrender deadline set by the Australian Clean Energy Regulator (CER) on Feb. 14.

For example, the current Current-Year (Forward), assessed through Feb. 14 , 2027, corresponds to CAL 26. The Current-Year (Forward) then rolls over to the next period, running from Feb. 15, 2027, to Feb. 14, 2028, which corresponds to CAL 27. Subsequent vintages will continue to roll over on Feb. 15 of each year.

Spot is defined as the latest available spot deliveries vintage for the LGC generated in the current calendar year.

A summary of the new assessment launches is provided below:

Each LGC represents the environmental attributes of renewable electricity and corresponds to one megawatt-hour of electricity generated from renewable sources, as certified and recorded in the REC Registry under the Clean Energy Regulator of Australia.

The assessment will be published in AUD/MWh at 4:30 pm Melbourne/Sydney/Canberra time, following the Penang holiday calendar.
