Installed capacity — Italy
What Italy 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 |
|---|---|---|
| Natural gas | 50,506+2,881 | 46.4% |
| Onshore wind | 12,875+642 | 11.8% |
| Solar | 11,872+2,950 | 10.9% |
| Run-of-river hydro | 10,491+174 | 9.6% |
| Pumped-storage hydro | 7,251+6 | 6.7% |
| Hard coal | 4,697−530 | 4.3% |
| Hydro reservoir | 4,496−52 | 4.1% |
| Other sources | 2,606+2,168 | 2.4% |
| Oil | 1,548 | 1.4% |
| Biomass | 1,474−65 | 1.4% |
| Geothermal | 868 | 0.8% |
| Waste | 70−601 | 0.1% |
| Offshore wind | 30 | 0.0% |
| Lignite | 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 108,784 MW installed, the most that ever ran at one moment was 87,639 MW — 81% of the fleet, on 08/01/2026, 11:30:00.
- Gas 58,892/ 52,054 MW 113%
- Hydro 19,362/ 22,238 MW 87%
- Wind 18,234/ 12,905 MW 141%
- Solar 39,196/ 11,872 MW 330%
- Coal 2,112/ 4,697 MW 45%
- Other 9,594/ 3,544 MW 271%
- Biomass 1,710/ 1,474 MW 116%
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 108,784MW +7,573
- 2025 101,211MW —
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.
