86348RESERVE NOTICE01/06/2021 09:58:56 AM
RESERVE NOTICE MT PASA PUBLICATION 01 June 2021
The MTPASA result published on 01 June 2021 identifies no Low Reserve Conditions.
Please note that MTPASA informs the market of potential reliability issues to allow the market to respond in the first instance, potentially avoiding the need for any market intervention or direction from AEMO.
For further information, please refer to:
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data/Market-Management-System-MMS/Projected-Assessment-of-System-Adequacy
This notice supersedes Market Notice 86075 published on 27th May 2021.
Background
As part of a broader process of implementing the reliability standard, AEMO runs the Medium Term Projected Assessment of System Adequacy (MTPASA) process weekly to forecast expected unserved energy levels over a two year period. If the expected annual unserved energy exceeds the maximum level specified by the Reliability Standard, a Low Reserve Condition is identified.
For more information about how AEMO implements the reliability standard, please view the Reliability Standard Implementation Guidelines (RSIG) available on AEMO's website at

86345GENERAL NOTICE31/05/2021 01:39:50 PM
Daily planned outage of Heywood No.1 500kV Busbar in Victoria region on 8th and 9th June 2021
AEMO ELECTRICITY MARKET NOTICE
This market notice is FOR INFORMATION ONLY.
The Heywood No.1 500kV busbar in Victoria Region is planned out of service on the following days.
-08/06/2021 on 0700hrs to 1900hrs
-09/06/2021 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:
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.
