Forecast Minimum System Load (MSL1) condition in the VIC region on 29/12/2024
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC region on 29/12/2024.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
o MSL1 - 1760 MW
o MSL2 - 1260 MW
o MSL3 - 760 MW
The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1000 hrs 29/12/2024 to 1400 hrs 29/12/2024. Minimum regional demand is forecast to be 1515 MW at 1230 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 .
