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 expected to be synchronised in SA from 1030 hrs 12/02/2021 to 1930 hrs 12/02/2021 in Pre-dispatch published at 1400 hrs 11/02/2021 are inadequate to maintain sufficient system strength in SA and hence a secure operating state.
