Reclassification of non-credible contingency event due to existence of widespread abnormal condition/s - SA region.
AEMO has identified that a non-credible contingency event impacting the power system is more likely to occur and is considered reasonably possible because of the existence of widespread abnormal conditions namely severe weather in the SA region.
AEMO has therefore reclassified the occurrence of a non-credible contingency event involving multiple plant due to these abnormal conditions as credible.
AEMO has taken the following action(s) to maintain power system security at 0220 hrs 08/07/2025.
Constraint set(s) invoked:
I-VS_250
Duration: 0220 hrs until further notice
Need for further measures is being monitored and further measures may be implemented in line with the Power System Security Guidelines (SO_OP_3715).
