Managing outages that create a credible risk of SA islanding
From 9th Oct 2024 AEMO will change constraints used during outages that create a credible risk of SA islanding.
From this date AEMO will:
1) Increase the maximum allowable flow on the V-SA interconnector from 50 MW to 250 MW in the VIC to SA direction, where the transmission outages is a planned outage.
2) Operate the SA region to the default 49-51 Hz target frequency containment band following a contingency event resulting in actual SA islanding. In order to meet this requirement, AEMO may now procure Contingency Raise FCAS locally from the SA region during these outages.
These changes reflect updated advice received by AEMO from the SA Jurisdictional System Security Coordinator.
The first network outage affected by this change is planned for 14th October 2024.
