Monticello nuclear power plant in context
By gross operating capacity Monticello nuclear power plant is the 53rd largest of 54 operating nuclear sites in the United States, holding 1% of the country's operating capacity, and ranks 164th of 172 worldwide.
Its operating unit started up in 1971; the unit is 55.0 years old, older than the median of 45.0 in the United States.
The one unit with both construction and grid dates on record took 3.7 years from construction start to grid connection; the median across all reactors connected in the 1970s is 5.4 years.
The nearest other tracked nuclear sites are Prairie Island nuclear power plant (124 km).
The current net rating of the unit differs from its design net capacity by +15.2% (545 MW at design, 628 MW now).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Monticello nuclear power plant | 1967 | 1971 | 3.7 | 5.4 (1970s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Prairie Island nuclear power plant | United States | 124 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.

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.
