114648MARKET INTERVENTION13/02/2024 05:21:13 PM
Possible intervention to manage power system security in VIC region
AEMO ELECTRICITY MARKET NOTICE
Possible intervention to manage power system security in VIC region
The synchronous generating units currently expected to be synchronised in VIC from 1830 hrs 13/02/2024 will be inadequate to maintain a secure operating state in VIC .
AEMO estimates that, in the absence of sufficient market response by 1730 hrs 13/02/2024, AEMO may need to intervene by issuing a direction requiring one or more VIC synchronous generating unit(s) to operate or remain synchronised to maintain power system security in VIC.

Reclassification of non-credible contingency event due to existence of widespread abnormal conditions - VIC region(s).
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 VIC region.
AEMO has therefore reclassified the occurrence of a non-credible contingency event involving multiple plant due to these abnormal conditions as credible.
Need for further measures is being monitored and further measures may be implemented in line with the Power System Security Guidelines (SO_OP_3715).
