Reclassification of a Non-Credible Contingency Event: Farrell - John Butters 220 kV Line and the Farrell - Rosebery Tee Queenstown - Newton 110 kV Line in Tasmania due to Lightning.
Lightning is occurring near the Farrell - John Butters 220 kV Line and the Farrell - Rosebery Tee Queenstown - Newton 110 kV Line.
AEMO considers the simultaneous trip of those circuits to now be more likely.
Therefore AEMO has reclassified this as a credible contingency event from 2210 hrs 19/05/16 until further notice.
