Reclassification of a Non-Credible Contingency Event: Chapel Street - Liapootah No. 1 and No. 2 220 kV Lines in Tasmania due to Lightning.
Reclassification of a Non-Credible Contingency Event: Chapel Street - Liapootah No. 1 and No. 2 220 kV Lines in Tasmania due to Lightning.
Lightning is occurring near the Chapel Street - Liapootah No. 1 and No. 2 220 kV Lines.
AEMO considers the simultaneous trip of those circuits to now be more likely.
Therefore AEMO has reclassified this as a credible contingency event from 1040 hrs 19 May 2016 until further notice.
