Forecast Minimum System Load (MSL1) condition in the VIC region on 16/02/2025

AEMO ELECTRICITY MARKET NOTICE

Update to Market Notice 124437 - AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC region on 16/02/2025.

Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
o MSL1 - 2115 MW
o MSL2 - 1615 MW
o MSL3 - 1115 MW

The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1200 hrs to 1500 hrs 16/02/2025. Minimum regional demand is forecast to be 1873 MW at 1330 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 .
