Update - Possible intervention to manage power system security in South Australia (SA) Region
AEMO ELECTRICITY MARKET NOTICE
Update - Possible intervention to manage power system security in South Australia (SA) Region
Refer AEMO Electricity Market Notice 90246
The synchronous generating units currently expected to be synchronised in SA from 0800 hrs 06/09/2021 to 1400 hrs 06/09/2021 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO estimates that, in the absence of sufficient market response by 0530 hrs 06/09/2021, 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.
