Almaraz nuclear power plant in context

By gross operating capacity Almaraz nuclear power plant is the 1st largest of 5 operating nuclear sites in Spain, holding 28% of the country's operating capacity, and ranks 83rd of 172 worldwide.

Its operating units started up between 1983 and 1984; the median unit is 42.5 years old, older than the median of 41.0 in Spain.

The 2 units with both construction and grid dates on record took 7.8 to 10.3 years (median 9.0) 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 Trillo nuclear power plant (279 km).

2 operating units are rated differently now from their design net capacities: Unit 1 +12.3% and Unit 2 +11.8%.

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.

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.
