84889MARKET INTERVENTION30/04/2021 01:59:22 PM
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
Refer Market Notice 84859
The synchronous generating units expected to be synchronised in SA from 0000 hrs 01/05/2021 to 1700 hrs 01/05/2021 in Pre-dispatch published at 1330 hrs 30/04/2021 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 1800 hrs 30/04/2021, 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.
