90427GENERAL NOTICE13/09/2021 10:11:59 AM
Planned outage of Heywood - South East No.1 line in the South Australia (SA) region on 15/09/2021 and 16/09/2021
AEMO ELECTRICITY MARKET NOTICE
The Heywood - South East No.1 line in the South Australia (SA) region is planned to be out of service as follows:
- 1530 hrs to 2300 hrs on 15/09/2021; and
- 1530 hrs to 2300 hrs on 16/09/2021.
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, contingency lower FCAS will be sourced from SA.
-When power transfer is from Victoria 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) to manage system security following the loss of the next contingency.
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-HYSE
I-VS_050
S-HYSE
V-HYTX_M12
Refer AEMO Network Outage Schedule (NOS) for further details.
