Update - Possible intervention to manage power system security in SA region

AEMO ELECTRICITY MARKET NOTICE

Update - Possible intervention to manage power system security in SA region

Refer AEMO Electricity Market Notice 117278

The synchronous generating units currently expected to be synchronised in SA from 0000 hrs 05/07/2024 will be inadequate to maintain a secure operating state in SA .

AEMO estimates that, in the absence of sufficient market response by 1300 hrs 04/07/2024, 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 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 0000 hrs 05/07/2024 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.
