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.
Region: NSW1
Lines: Armidale - Dumaresq 8C 330kV and Armidale - Sapphire WF 8E 330kV
