Comanche Peak nuclear power plant in context

By gross operating capacity Comanche Peak nuclear power plant is the 8th largest of 54 operating nuclear sites in the United States, holding 2% of the country's operating capacity, and ranks 56th of 172 worldwide.

Its operating units started up between 1990 and 1993; the median unit is 34.5 years old, younger than the median of 45.0 in the United States.

The 2 units with both construction and grid dates on record took 15.3 to 18.3 years (median 16.8) from construction start to grid connection; the median across all reactors connected in the 1990s is 8.0 years.

No other nuclear site with an exact position in this dataset lies within 300 km.

2 operating units are rated differently now from their design net capacities: Unit 1 +4.8% and Unit 2 +3.9%.

Build time by unit

UnitConstruction startGrid connectionYearsFleet median, same decade
Unit 11974199015.38.0 (1990s)
Unit 21974199318.38.0 (1990s)

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.
