Reclassification of a Non-Credible Contingency Event: Farrell-John Butters line and Farrell-Rosebery-Newton-Queenstown line in TAS1 due to Lightning.
Reclassification of a Non-Credible Contingency Event as a Credible Contingency Event due to Lightning. AEMO considers the simultaneous trip of the following circuits to now be more likely and reasonably possible. Accordingly AEMO has reclassified it as a credible contingency event.
Region: TAS1
Lines: Farrell-John Butters and Farrell-Rosebery-Newton-Queenstown
Duration: 31/05/2024 05:44 until further notice

Cancellation of a Non-Credible Contingency Event: Farrell - Reece No.1 220 kV line and Farrell - Reece No.2 220 kV line in TAS1 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.
