Spain Daily Load Shape and Duck Curve by Hour, 23 August to 19 September 2026

In the 28 complete local days from 23 August to 19 September 2026, electricity demand in Spain averaged 28,648 MW and typically peaked at 21:00 local time (32,955 MW) and bottomed out at 04:00 (23,365 MW). With solar and wind taken off, the remaining load fell to 3,709 MW at 15:00 and then rose 19,900 MW between 17:00 to 20:00. Hours are local clock time (Europe/Madrid).

Key Facts

  • Over 28 complete local days from 23 August to 19 September 2026, average demand in Spain was 28,648 MW. The hour of the day with the highest average demand was 21:00 local time (32,955 MW) and the lowest was 04:00 (23,365 MW).

Average Day by Local Hour

28 days to 2026-09-19, Europe/Madrid time
Spain average demand and net generation by local hour Average electricity demand in Spain by local clock hour over 28 complete local days from 23 August to 19 September 2026. It was lowest at 04:00 (23,365 MW) and highest at 21:00 (32,955 MW). Net generation is the power produced inside the grid, so it differs from demand by net imports. 0 10,000 20,000 30,000 40,000 00:0003:0006:0009:0012:0015:0018:0021:00

Each value is the mean over 28 complete local days from 23 August to 19 September 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 37,942 MW; it is a published reading, not an average, and is not part of the profile above.

Assumptions

  • Hours are local clock time in Europe/Madrid. 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 28 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 28 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.
