In accordance with section 116 of the National Electricity Law, AEMO has issued a direction to a participant in the SA region. For the purposes of the National Electricity Rules this is a direction under clause 4.8.9(a).

AEMO ELECTRICITY MARKET NOTICE

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

Refer AEMO Electricity Market Notice 100636

The synchronous generating units currently expected to be synchronised in SA from 2200 hrs 01/08/2022 will be inadequate to maintain a secure operating state in SA.

AEMO estimates that, in the absence of sufficient market response by 1500 hrs 01/08/2022, 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.
