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.
