92001GENERAL NOTICE28/10/2021 02:36:26 PM
Non-credible contingency event more likely to occur due to existence of abnormal condition/s - SA region.
AEMO ELECTRICITY MARKET NOTICE.
AEMO has identified that a non-credible contingency event is more likely to occur because of the existence of abnormal conditions namely severe weather in the SA region.
As at the time of this notice the criteria for reclassification of any non-credible contingency event have not been met, however there is a possibility of severe weather impacting multiple transmission elements in its vicinity.
Conditions can change rapidly and potentially impacted plant may change. Further notices will only be published to advise of any reclassification, or when the abnormal conditions have ceased to impact the likelihood of a non-credible event occurring.
Constraint set I-VS_250 invoked at 1440 hrs 28/10/2021 until further notice.
