The synchronous generating units currently expected to be synchronised in SA from 0200 hrs 06/01/2024 will be inadequate to maintain a secure operating state in SA.
AEMO estimates that, in the absence of sufficient market response by 1700 hrs 05/01/2024, 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.
