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 02/01/2021 0900 hrs to 02/01/2021 1900 hrs in Pre-dispatch published at 01/01/2021 1630 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 01/01/2021 1700 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.
