Possible intervention to manage power system security in South Australia (SA) Region
AEMO ELECTRICITY MARKET NOTICE
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units currently expected to be synchronised in SA from 0030 hrs 22/01/2022 will be inadequate to maintain a secure operating state in SA.
AEMO estimates that, in the absence of sufficient market response by 1300 hrs 21/01/2022, 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.
