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

In the 27 complete local days from 30 September to 27 October 2026, electricity demand in Bulgaria averaged 3,977 MW and typically peaked at 19:00 local time (4,723 MW) and bottomed out at 03:00 (3,151 MW). With solar and wind taken off, the remaining load fell to 1,224 MW at 11:00 and then rose 1,672 MW between 15:00 to 18:00. Hours are local clock time (Europe/Sofia).

Key Facts

  • Over 27 complete local days from 30 September to 27 October 2026, average demand in Bulgaria was 3,977 MW. The hour of the day with the highest average demand was 19:00 local time (4,723 MW) and the lowest was 03:00 (3,151 MW).
  • The largest three hour rise in average demand was 613 MW, between 16:00 to 19:00 local time.
  • The single highest hour of demand in the 30 day window was 5,471 MW, in the hour starting 27 Oct 2026, 18:00 EET (UTC+02:00).
  • Solar output averaged 2,841 MW at its 11:00 peak, 71% of average demand.
  • Demand minus solar and wind (net load) averaged 2,697 MW, fell to 1,224 MW at 11:00 and rose 1,672 MW over the three hours from 15:00 to 18:00, 42% of average demand.

Average Day by Local Hour

27 days to 2026-10-27, Europe/Sofia time
Bulgaria average demand and net generation by local hour Average electricity demand in Bulgaria by local clock hour over 27 complete local days from 30 September to 27 October 2026. It was lowest at 03:00 (3,151 MW) and highest at 19:00 (4,723 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 27 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 5,471 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/Sofia. 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 27 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 27 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.
