Fast Frequency Response Market - Removal of L1 FCAS dispatch cap from 9th September 2024
Following review of the operation of the Very Fast FCAS market, from 1300 hrs AEST on Monday 9th September AEMO will remove the 225 MW cap on dispatch of Very Fast Lower (L1) Contingency FCAS.
The 225 MW cap on dispatch of L1 FCAS sits well above typical disaptch volumes, and no immediate impact is expected from this change.
No other changes to the dispatch of Very Fast FCAS or FCAS constraint equation changes will be made on this date.
