The issue of the direction commences an AEMO intervention event. AEMO declares all dispatch intervals during the event to be intervention dispatch intervals, commencing from the interval ending 1705 hrs on 03/08/2021.

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 2230 hrs 03/08/2021 to 1630 hrs 04/08/2021 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.
