AEMO ELECTRICITY MARKET NOTICE
Update - Possible intervention to manage power system security in South Australia (SA) Region 29/03/2019
Refer AEMO Electricity Market Notice 67924
The synchronous generating units expected to be synchronised in SA from 0030 hrs 30/03/2019 to 1000 hrs 30/03/2019 in Pre-dispatch published at 1100 hrs 29/03/2019 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 1330 hrs 29/03/2019, 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.
