Clinton nuclear power plant in context
By gross operating capacity Clinton nuclear power plant is the 45th largest of 54 operating nuclear sites in the United States, holding 1% of the country's operating capacity, and ranks 140th of 172 worldwide.
Its operating unit started up in 1987; the unit is 39.0 years old, younger than the median of 45.0 in the United States.
The one unit with both construction and grid dates on record took 11.6 years 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 LaSalle nuclear power plant (120 km), Braidwood nuclear power plant (130 km) and Dresden nuclear power plant (144 km).
The current net rating of Unit 1 differs from its design net capacity by +11.8% (950 MW at design, 1,062 MW now).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1975 | 1987 | 11.6 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| LaSalle nuclear power plant | United States | 120 km | 2.4 |
| Braidwood nuclear power plant | United States | 130 km | 2.5 |
| Dresden nuclear power plant | United States | 144 km | 1.9 |
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 | Illinois, United States |

| Coordinates | 40.1719, -88.8339 |

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.
