Update - Foreseeable AEMO intervention in SA region
Refer AEMO Electricity Market Notice 125375
AEMO has identified a foreseeable circumstance that may require an AEMO intervention event in the SA region from 0400 hrs 09/03/2025.
The foreseeable circumstance requiring the need for intervention is Voltage.
AEMO estimates that, in the absence of sufficient market response by 1600 hrs 08/03/2025, AEMO may need to intervene by issuing a direction.
