Minimum System Load 1 (MSL1) in the VIC Region on 27/09/2024
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1300 hrs 27/09/2024 to 1330 hrs 27/09/2024.
Minimum regional demand is forecast to be 1879 MW at 1330 hrs, and the advisory threshold is:
o MSL1 - 1915 MW
o MSL2 - 1415 MW
o MSL3 - 915 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 action such as 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.
