Possible intervention to manage power system security in SA Region
The synchronous generating units currently expected to be synchronised in SA from 0100 hrs 20/06/2024 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
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.

The synchronous generating units currently expected to be synchronised in North QLD from 2100 hrs 14/06/2024 will be inadequate to maintain a secure operating state in North QLD.
AEMO estimates that, in the absence of sufficient market response by 2030 hrs 14/06/2024, AEMO may need to intervene by issuing a direction requiring one or more North QLD synchronous generating unit(s) to operate or remain synchronised to maintain power system security in QLD.
