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.

Participant Impact and Requirements: The following impacts are expected to participant connectivity during this planned outage on the 19th October 2024:
IPWAN Participants - A brief interuption of up to 60 seconds while services are failover from QLD to NSW Datacenter.
Lan-2-Lan VPN Participants (IPSEC) - Up to 2 hour outage for participants who have established their VPN connection/s via the AEMO QLD datacenter termination point (202.44.76.10) only - All L2L connections should be established to both QLD / NSW.
Note: Participants are encouraged to ensure their VPN connections are already established or are configured (as per AEMO best practice) to automatically failover to the alternate AEMO NSW datacenter termination point (202.44.78.10) prior to this scheduled outage.
B2B VPN - No impact is expected.
SSL VPN Participants: None expected as SSL VPN's are hosted on a different device.
GASHUB: No impact is expected as GASHUB will be failed over to the NSW Datacenter.
Other Impacts will have been communicated in advance.
** FAILURE TO ENSURE VPN FAILOVER WILL RESULT IN LOSS OF MARKETNET CONNECTIVITY **
Support Information:
Report any impacts to the AEMO Information and Support Hub or call 1300 236 600.
