Long Mott nuclear power plant in context
The nearest other tracked nuclear sites are South Texas nuclear power plant (78 km).
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| South Texas nuclear power plant | United States | 78 km | 2.7 |
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 | Texas, United States |
|---|---|
| Coordinates | 28.5033, -96.7745 |
| Elevation | about 10 mabove sea level |
| Setting | 3.2 km from the sea |
| Region | Northern America |
| Units by status | Pre-construction: 4 |
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.
