Grohnde nuclear power plant in context
The one unit with both construction and grid dates on record took 8.3 years 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.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Grohnde nuclear power plant | 1976 | 1984 | 8.3 | 7.3 (1980s) |
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.
| Location | Niedersachsen, Germany |
|---|---|
| Coordinates | 52.0356, 9.4135 |
| Elevation | about 70 mabove sea level |
| Setting | About 160 km from the sea |
| Region | Western Europe |
| Units by status | Retired: 1 |
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.
