Possible intervention to manage power system security in South Australia (SA) Region
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units currently expected to be synchronised in SA from 0130 hrs 20/01/2024 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.
