The Council welcomes the opportunity to provide feedback to the AEMC on the Enhancing Operational Resilience in Relation to Indistinct Events. Indistinct events are events that can impact multiple generators or transmission lines in an unpredictable and uncertain manner and may include major storms, bushfires and cyber-attacks, which may trigger unpredictable responses in an increasingly complex power system. These indistinct events are a threat to maintaining a secure supply of electricity to customers. This follows a recommendation made by the AEMC to enhance resilience in the power system, following the review of the South Australian black system event.
