ISO-NE Daily Load Shape and Duck Curve by Hour, 14 October to 11 November 2026

In the 29 complete local days from 14 October to 11 November 2026, electricity demand in ISO-NE averaged 11,580 MW and typically peaked at 18:00 local time (14,048 MW) and bottomed out at 12:00 (10,251 MW). With solar and wind taken off, the remaining load fell to 8,463 MW at 11:00 and then rose 3,298 MW between 14:00 to 17:00. Hours are local clock time (America/New_York).

Key Facts

  • Over 29 complete local days from 14 October to 11 November 2026, average demand in ISO-NE was 11,580 MW. The hour of the day with the highest average demand was 18:00 local time (14,048 MW) and the lowest was 12:00 (10,251 MW).
  • The largest three hour rise in average demand was 2,929 MW, between 14:00 to 17:00 local time.
  • The single highest hour of demand in the 30 day window was 14,849 MW, in the hour starting 14 Oct 2026, 18:00 EDT (UTC-04:00).
  • Solar output averaged 763 MW at its 12:00 peak, 7% of average demand.
  • Demand minus solar and wind (net load) averaged 10,100 MW, fell to 8,463 MW at 11:00 and rose 3,298 MW over the three hours from 14:00 to 17:00, 28% of average demand.

Average Day by Local Hour

29 days to 2026-11-11, America/New_York time
ISO-NE average demand and net generation by local hour Average electricity demand in ISO-NE by local clock hour over 29 complete local days from 14 October to 11 November 2026. It was lowest at 12:00 (10,251 MW) and highest at 18:00 (14,048 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 3,750 7,500 11,250 15,000 00:0003:0006:0009:0012:0015:0018:0021:00

Each value is the mean over 29 complete local days from 14 October to 11 November 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 14,849 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.
