Temelin nuclear power plant in context
By gross operating capacity Temelin nuclear power plant is the 1st largest of 2 operating nuclear sites in the Czech Republic, holding 52% of the country's operating capacity, and ranks 78th of 172 worldwide.
Its operating units started up between 2002 and 2003; the median unit is 23.5 years old, younger than the median of 39.5 in the Czech Republic.
The 2 units with both construction and grid dates on record took 13.9 to 15.9 years (median 14.9) from construction start to grid connection; the median across all reactors connected in the 2000s is 6.8 years.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1987 | 2000 | 13.9 | 6.8 (2000s) |
| Unit 2 | 1987 | 2002 | 15.9 | 6.8 (2000s) |
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.
