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 0100 hrs 28/02/2024 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1700 hrs 27/02/2024, 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.
