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 synchronous generating units currently expected to be synchronised in SA from 0030 hrs 11/07/2021 to 1630 hrs 11/07/2021 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO estimates that, in the absence of sufficient market response by 1700 hrs 10/07/2021 , 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.

Planned outage of Heywood 500kV bus no 2 outage in Victoria (VIC) region on 14, 21,22,23 July 2021
AEMO ELECTRICITY MARKET NOTICE
This market notice is FOR INFORMATION ONLY.
Heywood 500kV bus no 2 outages is planned to be out on the following periods.
-0700 hrs to 1700 hrs on 14 July 2021
-0700 hrs to 1700 hrs on 21 July 2021
-0700 hrs to 1700 hrs on 22 July 2021
-0700 hrs to 1700 hrs on 23 July 2021
A credible contingency event during this planned outage could cause synchronous separation of the South Australia (SA) region from the rest of the NEM. If separation occurs, load may be interrupted due to the operation of the Automatic Under Frequency Load Shedding (AUFLS) scheme in SA.
The credible separation contingency is managed as follows:
When power transfer is from SA to Victoria (Vic), contingency lower FCAS will be sourced from SA.
When power transfer is from Vic to SA, due to the 47-52Hz island separation frequency band advised by the SA jurisdiction, contingency raise FCAS is not sourced in SA and the AUFLS scheme may respond to low frequency events.
Power transfer will be restricted on Victoria - South Australia interconnector (Heywood interconnector).
Forecast capacity reserves in the SA region are currently sufficient to meet electricity demand during the planned outage.
The following constraint sets have been invoked for this outage:
F-I-HYSE
I-VS_050
S-X_BC_CP
V-HYTX_M12
V-HY_500BUS
Refer AEMO Network Outage Schedule (NOS) for further details.
