CPLW Daily Electricity Demand by Hour of Day, 29 September to 27 October 2026

In the 29 complete local days from 29 September to 27 October 2026, electricity demand in CPLW averaged 475 MW and typically peaked at 19:00 local time (546 MW) and bottomed out at 02:00 (379 MW). Hours are local clock time (America/New_York).

Key Facts

  • Over 29 complete local days from 29 September to 27 October 2026, average demand in CPLW was 475 MW. The hour of the day with the highest average demand was 19:00 local time (546 MW) and the lowest was 02:00 (379 MW).
  • The largest three hour rise in average demand was 40 MW, between 14:00 to 17:00 local time.
  • The single highest hour of demand in the 30 day window was 673 MW, in the hour starting 15 Oct 2026, 17:00 EDT (UTC-04:00).

Average Day by Local Hour

29 days to 2026-10-27, America/New_York time
CPLW average demand and net generation by local hour Average electricity demand in CPLW by local clock hour over 29 complete local days from 29 September to 27 October 2026. It was lowest at 02:00 (379 MW) and highest at 19:00 (546 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 150 300 450 600 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. Solar is left out of the net load calculation for CPLW: 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 673 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/New_York. 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.
