Environment: Production
Participant Impact and Requirements:
The following impacts are expected to participant connectivity during this planned outage:
IPWAN Participants - Nil
Lan-2-Lan VPN Participants (IPSEC) - Up to 6 hours 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 - Up to 30 minutes outage to TNSPs with B2B VPN to AEMO QLD Datacentre if VPN connection is only terminating in QLD only
SSL VPN Participants: Up to 30 minutes outage to TNSPs with B2B VPN to AEMO QLD Datacentre if VPN connection is only terminating in QLD only
Other Impacts will have been communicated in advance.
Support Information:
Report any impacts to the AEMO Information and Support Hub or call 1300 236 600.

Possible intervention to manage power system security in SA Region
Possible intervention to manage power system security in SA Region
The synchronous generating units currently expected to be synchronised in SA from 0000 hrs 02/03/2024 will be inadequate to maintain a secure operating state in SA.
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.
