1st largest plant in Pennsylvania · 14th nationally
Peach Bottom is a nuclear power plant in Pennsylvania with a nameplate capacity of 2,876 MW. It generates roughly 22.2M MWh per year — enough to power about 2,114,008 average U.S. homes.
Its capacity factor of 88% means it runs nearly around-the-clock as baseload generation.

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.
