Update - Possible intervention to manage power system security in South Australia (SA) Region
Refer AEMO Electricity Market Notice 93108
The synchronous generating units currently expected to be synchronised in SA from 0400 hrs 11/12/2021 to 0400 hrs 12/12/2021 will be inadequate to maintain a secure operating state in SA.
AEMO estimates that, in the absence of sufficient market response by 1600 hrs 10/12/2021, 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.
