Market Notices

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.

AEMO ELECTRICITY MARKET NOTICE

Following a review of the operation of the Very Fast FCAS market, AEMO will commence local dispatch of Very Fast FCAS in the South Australia (SA) and Queensland (QLD) regions from 10th June 2025, during periods where islanding of the region is considered credible.

An initial dispatch cap of 100 MW will apply in the SA region, and 20 MW in the QLD region. These caps will be reviewed and updated regularly.

From the same date, AEMO will also dispatch Very Fast FCAS in the QLD region when an actual islanding event occurs. In this scenario, no dispatch cap will apply.

Dispatch of Very Fast FCAS in the SA region under actual islanding conditions commenced in 2024. Refer to Market Notice 117238 for further details.
