Average Day by Local Hour

29 days to 2026-11-04, America/Phoenix time
WALC average demand and net generation by local hour Average electricity demand in WALC by local clock hour over 29 complete local days from 7 October to 4 November 2026. It was lowest at 02:00 (650 MW) and highest at 19:00 (1,034 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 1,505 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/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.
