AEMO ELECTRICITY MARKET NOTICE.

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 to maintain power system security at 2120 hrs 06/07/2024.

Constraint set invoked: I-VS_250

Duration: 2120 hrs 06/07/2024 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).
