AEMO ELECTRICITY MARKET NOTICE
Forecast Minimum System Load MSL1 condition in the VIC Region on 01/01/2025
Update to Market Notice 122588
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC on 01/01/2025.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
- MSL1 - 1560 MW
- MSL2 - 1060 MW
- MSL3 - 560 MW
The regional demand is forecast to be below the MSL1 threshold for the following period[s]:
- From 1100 hrs 01/01/2025 to 1400 hrs 01/01/2025. Minimum regional demand is forecast to be 1321 MW at 1300 hrs.
Forecast regional demand (DEMAND50) is published in Short Term and Pre-Dispatch PASA region solution reports available on Market Data NEMWEB: https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/data-nem/market-data-nemweb .
