Possible intervention to manage power system security in South Australia (SA) Region
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units expected to be synchronised in SA from 1000 hrs 03/09/2020 to 1630 hrs 03/09/2020 in Pre-dispatch published at 1430 hrs 03/09/2020 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 1530 hrs 03/09/2020 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.
