Residual Load in Europe: Demand Minus Wind and Solar, to 2026-11-05 (5 November 2026)
Across 37 European bidding zones, wind and solar together supplied a median 27% of demand from 7 October to 5 November 2026, ranging from 2% in Slovakia to 180% in Sweden North-Central (SE2). In 17 zones they covered all of demand in at least one hour, and in 5 they covered at least half of it in more than half of all hours.
Residual load is what hydro, nuclear, thermal plants, storage and imports have to supply once wind and solar have produced what they can. Hourly ENTSO-E data for 37 bidding zones over 7 October to 5 November 2026, in each zone's own local time. A window of a few weeks, not a yearly average: the seasonal view below adds the last 12 months.
Key Facts
- From 7 October to 5 November 2026, wind and solar supplied 180% of demand in Sweden North-Central (SE2), the highest of 37 European bidding zones, and a median 27% across all of them.
- Wind and solar covered at least half of demand in more than half of all hours in 5 of 37 zones (Sweden North-Central (SE2), Sweden North (SE1), Italy South and 2 more), and covered all of it in at least one hour in 17 zones.
- The highest hour of residual load was a median 8% below the highest hour of demand, so wind and solar reduced the peak other plants had to meet by that much in the 7 October to 5 November 2026 window.
- In 32 of 37 zones the typical day's residual load peaked in the evening, between 17:00 and 22:00 local time.
- Germany and Luxembourg, the largest zone in the set, had an average residual load of 27,616 MW against average demand of 54,996 MW, ranging from -9,272 MW to 60,686 MW hour to hour.
What the Numbers Show
7 October to 5 November 2026Coverage differs enormously between zones. Wind and solar supplied 180% of demand in Sweden North-Central (SE2) and 2% in Slovakia. The five highest were Sweden North-Central (SE2), Sweden North (SE1), Italy South, Denmark West (DK1) and Italy Sicily; 7 of 37 zones were below 10%, including Slovakia, Bosnia and Herzegovina, Norway South-East (NO1) and 4 more. The median zone sat at 27%. Coverage above 100% means the zone produced more wind and solar than it used over the window.
Full coverage is common in a few zones and rare in most. Wind and solar were at or above demand in at least one hour in 17 of 37 zones, and in at least a tenth of all hours in 9 of them (Sweden North-Central (SE2), Sweden North (SE1), Italy South, Denmark West (DK1) and 5 more). In 5 zones they covered at least half of demand in more than half of the hours: Sweden North-Central (SE2), Sweden North (SE1), Italy South, Denmark West (DK1) and Italy Calabria. The data does not say where the surplus went: it can be exported, stored or curtailed.
Wind and solar cut the peak far less than they cut the energy. Over the window the highest hour of residual load was a median 8% below the highest hour of demand, against a median 27% energy share. The reduction ranged from 1% in Switzerland to 42% in Latvia. In the single hour of highest demand, wind and solar supplied a median 21% of demand, so plants and imports that can be called on are still needed for the hours that set the peak, even where wind and solar supply a large share of the energy.
The residual peak moves to the evening. On the typical day, residual load peaked between 17:00 and 22:00 local time in 32 of 37 zones, and in 9 zones it peaked later than demand itself does, for example Italy South, Lithuania, Greece and 6 more. That fits solar output falling away while evening demand is still high, the effect the load shapes pages call the duck curve; in windy zones the peak can fall at any hour.
A few weeks are not the whole year. In the 12 months to October 2026 the median zone's lowest month had wind and solar at 14% of demand and its highest month at 40%. 24 of 35 zones with a complete calendar year had a higher share in the 7 October to 5 November 2026 window than in that year as a whole. On the median zone, wind and solar covered at least half of demand on 6% of days.

Residual load is demand minus wind minus solar in each hour; the average is over the hours used, shown in the last column. Lowest and highest hour are single hours in the window: a negative lowest hour means wind and solar together exceeded demand. Hours at least half covered counts hours in which wind plus solar was at least half of demand; hours fully covered counts hours in which residual load was zero or below. Peak hours are the clock hour with the highest average value on a typical day, in local time. Percentages are of the hours used.

Latest complete year is the newest calendar year with every day reported, so it can be 2025 for one zone and 2024 for another. Days are local days from the daily series (about 400 days to 2026-11-05), and only days on which demand, wind and solar are all reported count. Zones without a daily wind and solar series are left out of these two tables.

How Residual Load Is Measured, and What Is Left Out
- Residual load in an hour is demand minus wind minus solar. Demand is ENTSO-E actual total load; wind and solar are actual generation by type. Small negative wind or solar readings (stations drawing power overnight) are counted as zero.
- An hour is used only when demand, wind and solar are all present, so every figure for a zone is over the same hours. A zone needs at least 336 used hours and at least 90% of its hours with demand. Hours are the zone's local clock hours, so a clock change moves the pattern with it; the repeated hour on a 25 hour day is averaged.
- Residual load is a gap, not a fuel: the plants and imports that fill it are not identified here. Embedded rooftop solar that the operator does not report is missing from both generation and, partly, from load, so residual load can be overstated where that is large.
- Zones that are part of a country (Italy, Sweden, Norway and Denmark have several) are separate market areas, so a zone's wind and solar can exceed its own demand while the country as a whole does not.
- Left out: Albania (publishes no wind series that is reported); Belgium (fewer than 336 hours, or under 90% of its demand hours, have wind, solar and demand all reported); Georgia (publishes no solar series that is reported); Ireland and Northern Ireland (SEM) (publishes no hourly demand); Kosovo (publishes neither a wind nor a solar series that is reported); Montenegro (publishes no solar series that is reported); Norway Central (NO3) (publishes no solar series that is reported); Norway North (NO4) (publishes no solar series that is reported); Norway South-West (NO2) (publishes no solar series that is reported); Norway West (NO5) (publishes neither a wind nor a solar series that is reported); Serbia (publishes no solar series that is reported). A zone that publishes only one of the two is not ranked, because leaving the other out would understate its coverage.
- The window is 7 October to 5 November 2026, a stretch of weeks in one part of the year. Wind and solar output change with the season, so the ranking and the peak hours would differ in another month. The seasonal tables use daily totals for the last 12 months to show how far.
- Figures are as published by ENTSO-E, whose members can revise them. Only derived statistics are shown; raw hourly series are not offered for download. See methodology for time zones and units.
Residual Load: Questions and Answers
What is residual load?
Residual load is electricity demand minus the output of wind and solar plants. It is what the rest of the system has to supply in that hour: hydro, nuclear, gas, coal, biomass, batteries and pumped storage, and imports from neighbouring zones.
Which European zones had the most of their demand covered by wind and solar?
In 7 October to 5 November 2026, Sweden North-Central (SE2) had the highest coverage, with wind and solar equal to 180% of its demand. Next were Sweden North (SE1), Italy South, Denmark West (DK1) and 33 more. The list covers 37 zones with enough reported data, and it is a window of a few weeks, not a year.
Can wind and solar produce more than a zone uses?
Yes. In 17 of 37 zones there was at least one hour in the window in which wind and solar output was at or above demand, so residual load was zero or negative. The surplus is exported to neighbours, stored or curtailed; this data does not show which.
Does residual load mean gas and coal?
No. Residual load is a gap, not a fuel. In a zone with a lot of hydro or nuclear, those plants cover most of it, and imports can cover part of it. The page does not split residual load by the fuel that meets it.
