local timeUTC+1Installed capacity — Sweden
What Sweden 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 |
|---|---|---|
| Hydro reservoir | 16,416 | 37.3% |
| Onshore wind | 14,274 | 32.4% |
| Nuclear | 6,800 | 15.4% |
| Other sources | 6,538 | 14.8% |
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 44,028 MW installed, the most that ever ran at one moment was 28,298 MW — 64% of the fleet, on 20/02/2026, 18:45:00.
- Hydro 12,858/ 16,416 MW 78%
- Wind 13,124/ 14,274 MW 92%
- Nuclear 7,059/ 6,800 MW 104%
- Other 2,265/ 6,538 MW 35%
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.
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.
