Mochovce nuclear power plant in context
By gross operating capacity Mochovce nuclear power plant is the 1st largest of 2 operating nuclear sites in Slovakia, holding 60% of the country's operating capacity, and ranks 115th of 172 worldwide.
Its operating units started up between 1998 and 2023; the median unit is 26.0 years old, younger than the median of 28.0 in Slovakia.
The 3 units with both construction and grid dates on record took 14.7 to 36.0 years (median 16.2) from construction start to grid connection; the median across all reactors connected in the 1990s is 8.0 years.
The nearest other tracked nuclear sites are Bohunice nuclear power plant (62 km), Paks nuclear power plant (189 km) and Dukovany nuclear power plant (193 km).
2 operating units are rated differently now from their design net capacities: Unit 1 +14.5% and Unit 2 +15.0%.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1983 | 1998 | 14.7 | 8.0 (1990s) |
| Unit 2 | 1983 | 1999 | 16.2 | 8.0 (1990s) |
| Unit 3 | 1987 | 2023 | 36.0 | 7.7 (2020s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Bohunice nuclear power plant | Slovakia | 62 km | 1.0 |
| Paks nuclear power plant | Hungary | 189 km | 2.0 |
| Dukovany nuclear power plant | Czech Republic | 193 km | 2.0 |
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.
