Ignalina nuclear power plant in context
The 2 units with both construction and grid dates on record took 6.7 to 9.6 years (median 8.1) 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 Astravets nuclear power plant (98 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1977 | 1983 | 6.7 | 7.3 (1980s) |
| Unit 2 | 1978 | 1987 | 9.6 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Astravets nuclear power plant | Belarus | 98 km | 2.4 |
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 | Utenos, Lithuania |
|---|---|
| Coordinates | 55.6023, 26.5598 |
| Elevation | about 145 mabove sea level |
| Setting | About 220 km from the sea |
| Region | Northern Europe |
| Units by status | Retired: 2 |
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.
