⚛ Nuclear Power Plants in Minnesota
Minnesota operates 2 nuclear power plants totaling 1,871 MW of nameplate capacity. Annual generation: 11.9M MWh.
Nuclear plants generate carbon-free baseload electricity by fissioning uranium fuel inside a reactor. They run nearly around-the-clock — typical capacity factors above 90% — and a single facility can power millions of homes. Spent fuel is stored on-site in dry casks. NRC oversees safety; emergency planning zones extend 10 miles from the reactor.
