South Texas nuclear power plant

South Texas nuclear power plant in context

By gross operating capacity South Texas nuclear power plant is the 5th largest of 54 operating nuclear sites in the United States, holding 3% of the country's operating capacity, and ranks 52nd of 172 worldwide.

Its operating units started up between 1988 and 1989; the median unit is 37.5 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 12.3 to 13.3 years (median 12.8) from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 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 +2.4% and Unit 2 +2.4%.

Build time by unit

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.
