87715GENERAL NOTICE28/06/2021 09:40:49 AM
Daily planned outage of Heywood-Mortlake PS 500kV line in Victoria region on 12th, 13th, 14th July 2021
AEMO ELECTRICITY MARKET NOTICE
This market notice is FOR INFORMATION ONLY.
Heywood-Mortlake PS 500kV line in Victoria Region is planned out of service on the following days.
-12/07/2021 on 0700hrs to 1900hrs
-13/07/2021 on 0700hrs to 1900hrs
-14/07/2021 on 0700hrs to 1900hrs
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:
I-VS_050
S-X_BC_CP
V-HYMO
Refer AEMO Network Outage Schedule (NOS) for further details.
