Portugal Daily Load Shape and Duck Curve by Hour, 30 September to 27 October 2026

In the 28 complete local days from 30 September to 27 October 2026, electricity demand in Portugal averaged 5,840 MW and typically peaked at 19:00 local time (7,236 MW) and bottomed out at 04:00 (4,614 MW). With solar and wind taken off, the remaining load fell to 2,630 MW at 13:00 and then rose 2,691 MW between 16:00 to 19:00. Hours are local clock time (Europe/Lisbon).

Key Facts

  • Over 28 complete local days from 30 September to 27 October 2026, average demand in Portugal was 5,840 MW. The hour of the day with the highest average demand was 19:00 local time (7,236 MW) and the lowest was 04:00 (4,614 MW).
  • The largest three hour rise in average demand was 1,121 MW, between 16:00 to 19:00 local time.
  • The single highest hour of demand in the 30 day window was 7,930 MW, in the hour starting 27 Oct 2026, 19:00 WET (UTC+00:00).
  • Solar output averaged 2,625 MW at its 13:00 peak, 45% of average demand.
  • Demand minus solar and wind (net load) averaged 3,956 MW, fell to 2,630 MW at 13:00 and rose 2,691 MW over the three hours from 16:00 to 19:00, 46% of average demand.

Average Day by Local Hour

28 days to 2026-10-27, Europe/Lisbon time
Portugal average demand and net generation by local hour Average electricity demand in Portugal by local clock hour over 28 complete local days from 30 September to 27 October 2026. It was lowest at 04:00 (4,614 MW) and highest at 19:00 (7,236 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

Each value is the mean over 28 complete local days from 30 September to 27 October 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 7,930 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/Lisbon. 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.
