Cancellation of a Non-Credible Contingency Event: Collinsville - Stoney Creek 7306 132KV LINE line and Collinsville - Newlands 7121 132KV LINE line in QLD1 due to Lightning.
Cancellation of reclassification of a Non-Credible Contingency Event as a Credible Contingency Event due to Lightning. AEMO considers the simultaneous trip of the following circuits is no longer reasonably possible. There is no longer any lightning activity in the vicinity of the following lines. Accordingly its classification has reverted to a non-credible contingency event.

Forecast Minimum System Load (MSL1) condition in the VIC region on 03/11/2024
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC region on 03/11/2024.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
o MSL1 - 1770 MW
o MSL2 - 1270 MW
o MSL3 - 770 MW
The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1100 hrs to 1400 hrs 03/11/2024. Minimum regional demand is forecast to be 1424 MW at 1300 hrs.
Forecast regional demand (DEMAND50) is published in Short Term and Pre-Dispatch PASA region solution reports available on Market Data NEMWEB: https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/data-nem/market-data-nemweb .
