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 0600 hrs 10/03/2019 to 1500 hrs 10/03/2019 in Pre-dispatch published at 1400 hrs 09/03/2019 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 1500 hrs 09/03/2019, 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.
