88875GENERAL NOTICE26/07/2021 01:12:50 PM
Daily planned outage of Heywood No.2 500kV Busbar and Heywood- Mortlake PS 500kV line in Victoria region on 2 and 3 August 2021
AEMO ELECTRICITY MARKET NOTICE
The Heywood No.2 500 kV busbar and Heywood-Mortlake PS 500kV line in Victoria Region is planned out of serviice on the following periods:
-0700hrs to 1700hrs on 02/08/2021
-0700hrs to 1700hrs on 03/08/2021
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:
-V-HYMO
-F-I-HYSE
-S-X_BC_CP
-V-HYTX_M12
-V-HY_500BUS
-I-VS_050
Refer AEMO Network Outage Schedule (NOS) for further details.
