Possible intervention to manage power system security in SA Region
AEMO ELECTRICITY MARKET NOTICE
Possible intervention to manage power system security in SA Region
The synchronous generating units currently expected to be synchronised in SA from 2130 hrs 11/06/2024 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
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.
