Possible intervention to manage power system security in SA Region

AEMO ELECTRICITY MARKET NOTICE

Possible intervention to manage power system security in SA Region

The synchronous generating units currently expected to be synchronised in SA from 2100 hrs 03/01/2024 will be inadequate to maintain a secure operating state in SA.
AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to operate or remain synchronised to maintain power system security in SA.
