3rd largest plant in Texas · 41st nationally
Comanche Peak is a nuclear power plant in Texas with a nameplate capacity of 2,430 MW. It generates roughly 18.9M MWh per year — enough to power about 1,799,307 average U.S. homes.
Its capacity factor of 89% 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.
