LGEE Daily Electricity Demand by Hour of Day, 22 August to 19 September 2026

In the 29 complete local days from 22 August to 19 September 2026, electricity demand in LGEE averaged 5,061 MW and typically peaked at 17:00 local time (6,397 MW) and bottomed out at 04:00 (3,796 MW). Hours are local clock time (America/New_York).

Key Facts

  • Over 29 complete local days from 22 August to 19 September 2026, average demand in LGEE was 5,061 MW. The hour of the day with the highest average demand was 17:00 local time (6,397 MW) and the lowest was 04:00 (3,796 MW).
  • The largest three hour rise in average demand was 283 MW, between 14:00 to 17:00 local time.
  • The single highest hour of demand in the 30 day window was 7,581 MW, in the hour starting 3 Sept 2026, 15:00 EDT (UTC-04:00).

Average Day by Local Hour

29 days to 2026-09-19, America/New_York time
LGEE average demand and net generation by local hour Average electricity demand in LGEE by local clock hour over 29 complete local days from 22 August to 19 September 2026. It was lowest at 04:00 (3,796 MW) and highest at 17:00 (6,397 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 2,000 4,000 6,000 8,000 00:0003:0006:0009:0012:0015:0018:0021:00
Average electricity demand in LGEE by local clock hour over 29 complete local days from 22 August to 19 September 2026. It was lowest at 04:00 (3,796 MW) and highest at 17:00 (6,397 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports.

Each value is the mean over 29 complete local days from 22 August to 19 September 2026, weekdays and weekends together, for the hour starting at that local clock time. Solar is left out of the net load calculation for LGEE: 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 7,581 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.
