Average Day by Local Hour

29 days to 2026-11-04, America/Los_Angeles time
PSEI average demand and net generation by local hour Average electricity demand in PSEI by local clock hour over 29 complete local days from 7 October to 4 November 2026. It was lowest at 02:00 (2,196 MW) and highest at 19:00 (3,056 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 1,000 2,000 3,000 4,000 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. Solar is left out of the net load calculation for PSEI: 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 3,662 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/Los_Angeles. 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.
