AEMO ELECTRICITY MARKET NOTICE

Update Possible intervention to manage power system security in South Australia (SA) Region

Refer AEMO Electricity Market Notice 76496

The synchronous generating units expected to be synchronised in SA from 0930 hrs 01/08/2020 to 1530 hrs 01/08/2020 in Pre-dispatch published at 1430 hrs 30/07/2020 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 31/07/2020, 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.
