Installed capacity — Bulgaria
What Bulgaria 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 |
|---|---|---|
| Solar | 7,159+1,055 | 30.1% |
| Other sources | 5,406+4,024 | 22.8% |
| Lignite | 4,119 | 17.3% |
| Nuclear | 2,000 | 8.4% |
| Hydro reservoir | 1,807 | 7.6% |
| Pumped-storage hydro | 864 | 3.6% |
| Natural gas | 742+12 | 3.1% |
| Onshore wind | 715 | 3.0% |
| Run-of-river hydro | 547 | 2.3% |
| Hard coal | 330−6 | 1.4% |
| Biomass | 57 | 0.2% |
| Waste | 6 | 0.0% |
| Geothermal | 0 | 0.0% |
| Oil | 0 | 0.0% |
| Offshore wind | 0 | 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 23,752 MW installed, the most that ever ran at one moment was 7,713 MW — 32% of the fleet, on 20/01/2026, 10:00:00.
- Solar 4,471/ 7,159 MW 62%
- Other 2,251/ 5,412 MW 42%
- Coal 2,615/ 4,449 MW 59%
- Hydro 1,880/ 3,218 MW 58%
- Nuclear 1,960/ 2,000 MW 98%
- Gas 341/ 742 MW 46%
- Wind 589/ 715 MW 82%
- Biomass 24/ 57 MW 42%
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.
