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 1030 hrs 12/02/2021 to 1930 hrs 12/02/2021 in Pre-dispatch published at 1400 hrs 11/02/2021 are inadequate to maintain sufficient system strength in SA and hence a secure operating state.

AEMO currently estimates that, in the absence of sufficient market response by 1800 hrs 11/02/2021, 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.
