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 1700 hrs 18/12/2023 will be inadequate to maintain a secure operating state in SA .

AEMO estimates that, in the absence of sufficient market response by 1700 hrs 17/12/2023, 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.

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 currently expected to be synchronised in SA from 0100 hrs 18/12/2023 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.
