MISO Daily Load Shape and Duck Curve by Hour, 29 September to 27 October 2026

In the 29 complete local days from 29 September to 27 October 2026, electricity demand in MISO averaged 72,013 MW and typically peaked at 18:00 local time (80,221 MW) and bottomed out at 04:00 (62,337 MW). With solar and wind taken off, the remaining load fell to 49,061 MW at 10:00 and then rose 15,493 MW between 16:00 to 19:00. Hours are local clock time (America/New_York).

Key Facts

  • The single highest hour of demand in the 30 day window was 95,171 MW, in the hour starting 12 Oct 2026, 17:00 EDT (UTC-04:00).
  • Solar output averaged 15,196 MW at its 12:00 peak, 21% of average demand.
  • Demand minus solar and wind (net load) averaged 55,640 MW, fell to 49,061 MW at 10:00 and rose 15,493 MW over the three hours from 16:00 to 19:00, 22% of average demand.

Average Day by Local Hour

29 days to 2026-10-27, America/New_York time
MISO average demand and net generation by local hour Average electricity demand in MISO by local clock hour over 29 complete local days from 29 September to 27 October 2026. It was lowest at 04:00 (62,337 MW) and highest at 18:00 (80,221 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 25,000 50,000 75,000 100,000 00:0003:0006:0009:0012:0015:0018:0021:00

Each value is the mean over 29 complete local days from 29 September to 27 October 2026, weekdays and weekends together, for the hour starting at that local clock time. Net load is demand minus solar and wind generation. The single highest hour of demand in the whole 30 day window was 95,171 MW; it is a published reading, not an average, and is not part of the profile above.

Assumptions

  • Hours are local clock time in America/New_York. A local day is used only if it is whole inside the 30 day window and at least 22 of its hours are complete; the profile uses the 29 most recent such days. Daylight saving follows the local clock: on a clock change day the missing hour is absent and the repeated hour is averaged over both readings.
  • The average mixes weekdays and weekends and covers only 29 days, so it describes recent conditions, not a seasonal norm.
  • The evening ramp is the largest rise over three hours in the average profile, starting between 14:00 and 20:00 local time.
