Minimum System Load 1 (MSL1) in the VIC Region on 13/10/2024
AEMO ELECTRICITY MARKET NOTICE
Minimum System Load 1 (MSL1) in the VIC Region on 13/10/2024
Update to Market Notice 118749 - AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1200 hrs 13/10/2024 to 1230 hrs 13/10/2024.
Minimum regional demand is [forecast to be] 1557 MW at 1230 hrs, and the advisory threshold is:
? MSL1 - 1560 MW
? MSL2 - 1010 MW
? MSL3 - 510 MW
MSL events are forecast when forecast regional demand is less than the relevant MSL threshold. The forecast regional demand is below the xxx 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 such as rescheduling of planned network outages and increasing electricity consumption.
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.

Managing outages that create a credible risk of SA islanding
AEMO ELECTRICITY MARKET NOTICE
From 9th Oct 2024 AEMO will change constraints used during outages that create a credible risk of SA islanding.
From this date AEMO will:
1) Increase the maximum allowable flow on the V-SA interconnector from 50 MW to 250 MW in the VIC to SA direction, where the transmission outages is a planned outage.
2) Operate the SA region to the default 49-51 Hz target frequency containment band following a contingency event resulting in actual SA islanding. In order to meet this requirement, AEMO may now procure Contingency Raise FCAS locally from the SA region during these outages.
These changes reflect updated advice received by AEMO from the SA Jurisdictional System Security Coordinator.
The first network outage affected by this change is planned for 14th October 2024.
