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 5,152 MW installed, the most that ever ran at one moment was 3,214 MW — 62% of the fleet, on 19/02/2026, 16:30:00.

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 2015 to 2025.

  1. 2025 5,152MW +123
  2. 2024 5,029MW +512
  3. 2023 4,517MW +115
  4. 2022 4,402MW +153
  5. 2021 4,249MW −858
  6. 2020 5,107MW +150
  7. 2019 4,957MW +111
  8. 2018 4,846MW +69
  9. 2017 4,777MW +65
  10. 2016 4,712MW +75
  11. 2015 4,637MW

The figures come from the ENTSO-E Transparency Platform, installed generation capacity aggregated by production type. The year is the one the transmission 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.
