Update - Possible intervention to manage power system security in SA region
Refer AEMO Electricity Market Notice 115403
The synchronous generating units currently expected to be synchronised in SA from 0100 hrs 02/03/2024 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1700 hrs 01/03/2024, 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.
