TEPC Daily Load Shape and Duck Curve by Hour, 7 October to 4 November 2026

In the 29 complete local days from 7 October to 4 November 2026, electricity demand in TEPC averaged 1,522 MW and typically peaked at 17:00 local time (1,840 MW) and bottomed out at 03:00 (1,326 MW). With solar and wind taken off, the remaining load fell to 827 MW at 10:00 and then rose 587 MW between 14:00 to 17:00. Hours are local clock time (America/Phoenix).

Key Facts

  • Over 29 complete local days from 7 October to 4 November 2026, average demand in TEPC was 1,522 MW. The hour of the day with the highest average demand was 17:00 local time (1,840 MW) and the lowest was 03:00 (1,326 MW).
  • The largest three hour rise in average demand was 201 MW, between 14:00 to 17:00 local time.
  • The single highest hour of demand in the 30 day window was 2,518 MW, in the hour starting 8 Oct 2026, 16:00 MST (UTC-07:00).
  • Solar output averaged 440 MW at its 10:00 peak, 29% of average demand.
  • Demand minus solar and wind (net load) averaged 1,252 MW, fell to 827 MW at 10:00 and rose 587 MW over the three hours from 14:00 to 17:00, 39% of average demand.

Average Day by Local Hour

29 days to 2026-11-04, America/Phoenix time
TEPC average demand and net generation by local hour Average electricity demand in TEPC by local clock hour over 29 complete local days from 7 October to 4 November 2026. It was lowest at 03:00 (1,326 MW) and highest at 17:00 (1,840 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 500 1,000 1,500 2,000 00:0003:0006:0009:0012:0015:0018:0021:00

Each value is the mean over 29 complete local days from 7 October to 4 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 2,518 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 2026-11-04. Profiles are computed by World Power Monitor from the operator's hourly series.

Assumptions

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