Trillo nuclear power plant in context
By gross operating capacity Trillo nuclear power plant is the 5th largest of 5 operating nuclear sites in Spain, holding 14% of the country's operating capacity, and ranks 144th of 172 worldwide.
Its operating unit started up in 1988; the unit is 38.0 years old, younger than the median of 41.0 in Spain.
The one unit with both construction and grid dates on record took 8.8 years from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 years.
The nearest other tracked nuclear sites are Cofrentes nuclear power plant (213 km), Ascó nuclear power plant (274 km) and Almaraz nuclear power plant (279 km).
The current net rating of Unit 1 differs from its design net capacity by +1.3% (990 MW at design, 1,003 MW now).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1979 | 1988 | 8.8 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Cofrentes nuclear power plant | Spain | 213 km | 1.1 |
| Ascó nuclear power plant | Spain | 274 km | 2.1 |
| Almaraz nuclear power plant | Spain | 279 km | 2.1 |
How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.

Magnitude 4.0 and above within 200 km of Trillo nuclear power plant's listed coordinates, past 30 days. This is distance, not shaking: it says nothing about damage or any change in operation. Every plant.
| Location | Castilla-La Mancha, Spain |

Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
