Update - Possible intervention to manage power system security in SA region
Update - Possible intervention to manage power system security in SA region
Refer AEMO Electricity Market Notice 116914
The synchronous generating units currently expected to be synchronised in SA from 1000 hrs 10/06/2024 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1600 hrs 09/06/2024, 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.

Change End Date & Time: 07/07/2024 14:00:00 AEST
Outage Start Date & Time:
Outage End Date & Time:
Environment: Production
Participant Impact and Requirements: AEMO's FRC Gas Hub web services need to have their server certificates updated every year with new certificates to replace the expiring one.
Participants connecting to these endpoints or receiving requests from AEMO's FRC Gas Hub platforms and have authorisation mechanisms like certificate fingerprinting in place will notice a change in AEMO's server's certificate fingerprint and will need to update their systems accordingly.
The certificate relates to "FBS-Prod-Hub.aemo.com.au" certificate and relates to the following domains.
FBS-Prod-Hub.aemo.com.au
apis.prod.aemo.com.au
hub.aemo.com.au
prod.frchub.net
apis.prod.marketnet.net.au
hub.marketnet.net.au
Participants WILL need to update the profile that communicates with the above domains.
This will need to be done to avoid the inability to send messages to the relay.
The certificates can be downloaded from the link below:
