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 expected to be synchronised in SA from 0830 hrs 01/08/2020 to 1430 hrs 01/08/2020 are 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.
