Possible intervention to manage power system security in South Australia (SA) Region

AEMO ELECTRICITY MARKET NOTICE

Possible intervention to manage power system security in South Australia (SA) Region

The combination of synchronous generating units currently expected to be synchronised in SA from 0100 hrs 21/01/2021 will not provide sufficient system strength in SA to maintain the power system in a secure operating state.

In the absence of sufficient market response AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to operate or remain synchronised from 0100 hrs 21/01/2021 to maintain power system security in SA. Refer to current Transfer Limit Advice for SA system strength on AEMOs website.

If necessary, AEMO will estimate and publish the latest time at which AEMO would need to intervene after the 1230 hrs predispatch run on the 20/01/2021.

The synchronous generating units expected to be synchronised in SA from 0930 hrs to 1700 hrs 18/01/2021 in Pre-dispatch published at 1500 hrs 17/01/2021are inadequate to maintain sufficient system strength in SA and hence a secure operating state.
