Installed capacity — France
What France could produce with everything running at once: installed capacity by source, as reported for 2026, next to how much has actually run.
| Source | Capacity (MW) | Of total |
|---|---|---|
| Nuclear | 62,990 | 38.5% |
| Solar | 28,254+5,394 | 17.3% |
| Onshore wind | 23,672+765 | 14.5% |
| Natural gas | 12,801+13 | 7.8% |
| Run-of-river hydro | 11,748+11 | 7.2% |
| Hydro reservoir | 8,791 | 5.4% |
| Pumped-storage hydro | 5,061 | 3.1% |
| Oil | 2,986+7 | 1.8% |
| Hard coal | 1,811 | 1.1% |
| Offshore wind | 1,528+500 | 0.9% |
| Other sources | 1,492+226 | 0.9% |
| Biomass | 1,435+22 | 0.9% |
| Waste | 1,040−23 | 0.6% |
| Geothermal | 2 | 0.0% |
How much ran at once
The highest output delivered at a single moment over the past twelve months, by source group, next to the installed capacity.
Of 163,611 MW installed, the most that ever ran at one moment was 91,269 MW — 56% of the fleet, on 08/01/2026, 18:45:00.
- Nuclear 56,132/ 62,990 MW 89%
- Solar 22,325/ 28,254 MW 79%
- Hydro 16,095/ 25,600 MW 63%
- Wind 19,165/ 25,200 MW 76%
- Gas 10,289/ 15,787 MW 65%
- Other 907/ 2,534 MW 36%
- Coal 1,129/ 1,811 MW 62%
- Biomass 484/ 1,435 MW 34%
The peak is read from our own generation archive, not estimated: it is a lower bound on what the fleet can do. A small ratio means the group's sources never all ran together — reservoir hydro starts at peak demand, thermal plants sit idle when they are not called. A ratio above one hundred means the declared capacity has fallen behind: the figure is declared at the start of the year while new units come online during it. Groups are compared here rather than individual source types: the same source can report capacity under lignite and generation under coal, and at group level the two meet.
How it changed, year by year
Total installed capacity, from 2025 to 2026.
- 2026 163,611MW +6,916
- 2025 156,695MW —
The figures come from the ENTSO-E Transparency Platform: installed generation capacity by production type. The year is the one the operator reports for, not the year the figure was published.
Two things are not here: the number of installations per source, and batteries as a source of their own. The aggregated report does not carry them, and batteries fall under “other”. They appear the day the source publishes them separately.
