Forecast Minimum System Load MSL1 condition in the SA Region on 17/05/2026
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the SA on 17/05/2026.
Minimum System Load (MSL) conditions are forecast when demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
- MSL1: 603 MW
- MSL2: 328 MW
- MSL3: 113 MW
The demand is forecast to be below the MSL1 threshold for the following period[s]:
- From 1300 hrs 17/05/2026 to 1400 hrs 17/05/2026. Minimum demand is forecast to be 576 MW at 1400 hrs.
Forecast demand refers to forecast Operational Demand that excludes contribution from Significant Non-Scheduled Generation: see definitions at https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/operational-demand-data .
AEMO is seeking a market response.
