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 currently expected to be synchronised in SA from 2330 hrs 07/07/2021 to 0630 hrs 08/07/2021 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO estimates that, in the absence of sufficient market response by 1630 hrs 07/07/2021, 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.
