Average Day by Local Hour

29 days to 2026-10-27, America/Chicago time
TVA average demand and net generation by local hour Average electricity demand in TVA by local clock hour over 29 complete local days from 29 September to 27 October 2026. It was lowest at 03:00 (14,363 MW) and highest at 17:00 (21,144 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 6,250 12,500 18,750 25,000 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 generation. Wind is left out of the net load calculation for TVA: the series is missing, reads zero, or is under 3% of average demand in this window. The single highest hour of demand in the whole 30 day window was 44,377 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/Chicago. 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.
