NuclearWisconsinUnited States of AmericaCO₂ reported
Point Beach Nuclear Plant is a 1,311 MW nuclear power station in Wisconsin, United States of America. It is operated by NextEra Energy Point Beach LLC. Based on reported annual generation of 10,030 GWh, it can supply roughly 2,865,714 homes. It ranks #197 of 9,833 United States of America power plants by installed capacity. Commissioned in 1971, it is around 55 years old — an older, legacy facility. Its measured emissions of 16,421 t CO₂/yr (Climate TRACE) are equivalent to about 3,828 cars driven for a year. In context, nuclear supplies about 17.4% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 44.3°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 56% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 82/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #36 largest nuclear power plant of 58 in United States of America by capacity.
United States of America has 58 nuclear power plants in this dataset, together about 104,233 MW of capacity.
