Leningrad nuclear power plant in context
By gross operating capacity Leningrad nuclear power plant is the 1st largest of 10 operating nuclear sites in Russia, holding 15% of the country's operating capacity, and ranks 17th of 172 worldwide.
Its operating units started up between 1980 and 2021; the median unit is 26.5 years old, younger than the median of 37.5 in Russia.
The 6 units with both construction and grid dates on record took 3.8 to 10.5 years (median 6.0) 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 Loviisa nuclear power plant (160 km).
2 operating units are rated differently now from their design net capacities: Unit 2-1 +3.3% and Unit 2-2 +3.3%.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1-1 | 1970 | 1973 | 3.8 | 5.4 (1970s) |
| Unit 1-2 | 1970 | 1975 | 5.1 | 5.4 (1970s) |
| Unit 1-3 | 1973 | 1979 | 6.0 | 5.4 (1970s) |
| Unit 1-4 | 1975 | 1981 | 6.0 | 7.3 (1980s) |
| Unit 2-1 | 2008 | 2018 | 9.4 | 5.9 (2010s) |
| Unit 2-2 | 2010 | 2020 | 10.5 | 7.7 (2020s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Loviisa nuclear power plant | Finland | 160 km | 1.1 |
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.

Magnitude 4.0 and above within 200 km of Leningrad nuclear power plant's listed coordinates, past 30 days. This is distance, not shaking: it says nothing about damage or any change in operation. Every plant.
| Location | Leningrad, Russia |

Elevation is read at the listed coordinates from a 30 m terrain model (ASTER GDEM 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.
