AEMO ELECTRICITY MARKET NOTICE

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

The synchronous generating units expected to be synchronised in SA from 0830 hrs 01/02/2021 to the end of the Pre-dispatch period 0400 hrs 02/02/2021 in Pre-dispatch published at 1400 hrs 31/01/2021 are inadequate to maintain sufficient system strength in SA and hence a secure operating state.

AEMO currently estimates that, in the absence of sufficient market response by 1700 hrs 31/01/2021, 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.

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 26/01/2021 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 26/01/2021 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 25/01/2021.
