AEMO ELECTRICITY MARKET NOTICE

Possible intervention to manage power system security in QLD region

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.
