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 0100 hrs 20/06/2024 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.
