EPE 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 EPE averaged 988 MW and typically peaked at 16:00 local time (1,265 MW) and bottomed out at 04:00 (766 MW). With solar taken off, the remaining load fell to 399 MW at 10:00 and then rose 327 MW between 15:00 to 18:00. Hours are local clock time (America/Denver).

  • Solar output averaged 559 MW at its 14:00 peak, 57% of average demand.
  • Demand minus solar (net load) averaged 752 MW, fell to 399 MW at 10:00 and rose 327 MW over the three hours from 15:00 to 18:00, 33% of average demand.

Average Day by Local Hour

29 days to 2026-10-27, America/Denver time
EPE average demand and net generation by local hour Average electricity demand in EPE by local clock hour over 29 complete local days from 29 September to 27 October 2026. It was lowest at 04:00 (766 MW) and highest at 16:00 (1,265 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 375 750 1,125 1,500 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 generation. The single highest hour of demand in the whole 30 day window was 1,680 MW; it is a published reading, not an average, and is not part of the profile above.

Source: U.S. Energy Information Administration (EIA). (US Government work, public domain) Data as of 2026-10-27. Profiles are computed by World Power Monitor from the operator's hourly series.

Assumptions

  • Hours are local clock time in America/Denver. 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.
