AEMO ELECTRICITY MARKET NOTICE

Minimum System Load 1 (MSL1) in the VIC Region on 13/10/2024

Update to Market Notice 118834 - AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1030 hrs 13/10/2024 to 1330 hrs 13/10/2024.

Minimum regional demand is forecast to be 1265 MW at 1230 hrs, and the advisory threshold is:
- MSL1 - 1560 MW
- MSL2 - 1060 MW
- MSL3 - 560 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 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.
