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 17/12/2020 0130 hrs to 18/12/2020 0400 hrs in Pre-dispatch published at 16/12/2020 1430 hrs 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 16/12/2020 1800 hrs, AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to synchronise or remain synchronised to maintain power system security in SA.
