Non-credible contingency event more likely to occur due to existence of abnormal conditions - 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 damaging winds in the South Australia 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 0800 hrs 23/01/2020 until further notice.

Contingency event more likely to occur due to abnormal conditions - NSW region.- 23/01/2020
AEMO ELECTRICITY MARKET NOTICE.
Refer AEMO Electricity Market Notice No. 72574
AEMO has identified that abnormal conditions exist in the NSW region, namely DAMAGING WINDS and HEAVY RAINFALL in the Snowy Mountains and South West Slopes weather districts which increases the risk of a contingency event occurring.
Given the increased risk, AEMO has applied the following constraint to manage the impact of any such contingency event:
I-VN_0500
I-NV_0500
Further notices will only be published to advise of any additional limitations, or when the abnormal conditions have ceased to impact the likelihood of a contingency event occurring.
