118421MINIMUM SYSTEM LOAD24/09/2024 02:54:54 PM
Minimum System Load 1 (MSL1) in the VIC Region on 28/09/2024
AEMO ELECTRICITY MARKET NOTICE
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1100 hrs to 1400 hrs 28/09/2024.
Minimum regional demand is forecast to be 1638 MW at 1300 hrs, and the advisory threshold is:
- MSL1 - 1865 MW
- MSL2 - 1365 MW
- MSL3 - 865 MW
MSL events are forecast when forecast regional demand is less than the relevant MSL threshold. The forecast regional demand is below the MSL1 threshold.
Refer to NEM Data Dashboard to monitor demand levels: https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem
AEMO is seeking a market response.
An insufficient market response may require AEMO to take action or intervene to maintain power system security in Victoria. This may result in actions such as recalling network outages, the direction of scheduled production units, curtailment of non-scheduled production units, and/or a direction to maintain regional demand above required MSL threshold, in both Victoria and South Australia.

AEMO ELECTRICITY MARKET NOTICE.
Update - Lightning vulnerable lines in TAS region
Refer to AEMO Electricity Market Notice 118320 ,118321, 118322
At 1340 hrs 19/09/2024 the Gordon - Chapel St No 1 220 kV line and the Gordon - Chapel St No 2 220 kV line tripped.
The cause of the trip was identified as due to Lightning.
In accordance with SO_OP_3715, AEMO now considers the Gordon - Chapel St No 1 220 kV line and the Gordon - Chapel St No 2 220 kV line to be vulnerable with a category of Vulnerability due to Lightning.

Planned outage of Tailem Bend - South East 275 kV transmission line in the South Australia region beginning on 20/09/2024
AEMO ELECTRICITY MARKET NOTICE
The Tailem Bend - South East No 1 275 kV line in the South Australian (SA) region is planned to be out of service from 2100 hrs on 20/09/2024 to 0530 hrs on 21/09/2024.
A credible contingency event during this planned outage could cause synchronous separation of the SA region from the rest of the NEM.
During this planned outage:
- Power transfer will be restricted across the VIC - SA interconnector (Heywood interconnector); and
- Post contingent FCAS will be sourced within SA following Separation event.
Refer AEMO Network Outage Schedule (NOS) for further details.
