Platts proposes to launch Australian Large-scale Generation Certificate (LGC) price assessments March 30
Platts, part of S&P Global Energy, proposes to launch Australian Large-scale Generation Certificate (LGC) price assessments, effective March 30 , 2026.
The proposal responds to market feedback calling for greater price transparency in the Australian LGC market. The assessments would also complement Platts' existing offerings in the Australian energy transition and emissions reductions space, including the Platts Australian Carbon Credit Unit (ACCU) assessment suite.
The Australian LGC assessments would 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 would 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 would 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 proposed assessment launches is provided below:
| Assessment | Description | Vintage referred to on March 30, 2026 |
| Australia LGC Spot | LGCs already generated in the current calendar year and available for immediate delivery. | Spot |
| Australia LGC Current-Year (Forward) | LGCs to be generated later in the current calendar year, with forward delivery scheduled within the year. | CAL 26 |
| Australia LGC Year+1 | LGCs to be generated in the calendar year immediately following the current year, with delivery scheduled for that future year. | CAL 27 |
| Australia LGC Year+2 | LGCs to be generated in the second calendar year following the current year, with delivery scheduled for that future year. | CAL 28 |
| Australia LGC Year+3 | LGCs to be generated in the third calendar year following the current year, with delivery scheduled for that future year. | CAL 29 |
Each LGC represents the environmental attributes of renewable electricity and corresponds to one megawatt-hour of electricity generated from renewable sources, as issued within the REC Registry under the Clean Energy Regulator of Australia.
The assessment would be published in AUD/MWh daily at 4:30 pm Sydney/Canberra time, following the Penang, Malaysia publishing schedule.
