Cancellation of a Non-Credible Contingency Event: Armidale - Dumaresq 8C 330kV line and Armidale - Sapphire WF 8E 330kV line in NSW1 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.

o MSL1 - 1760 MW
o MSL2 - 1260 MW
o MSL3 - 760 MW
The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1000 hrs to 1430 hrs 10/11/2024. Minimum regional demand is forecast to be 1349 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 .
