STPASA - Suspect Lack Of Reserve Level 3 (LOR3) in the QLD Region on 01/02/2024
AEMO considers that there are suspect Forecast LOR3 conditions for the QLD region for the following periods:
1. From 0900 hrs to 1000 hrs 01/02/2024.
The maximum load (other than interruptible loads) forecast to be interrupted is 38 MW at 0930 hrs.
2. From 1130 hrs to 1200 hrs 01/02/2024.
The maximum load (other than interruptible loads) forecast to be interrupted is 62 MW at 1130 hrs.
AEMO is currently investigating these LOR3 forecast conditions to confirm whether they are valid.
