Vermont Yankee is a 604-megawatt nuclear power plant that provided 42 years of reliable electricity to New England’s electric consumers with stable fuel costs and no air pollution during operations. Over its lifetime, Vermont Yankee produced over 171 billion kilowatt-hours of electricity, providing 71.8 percent of the electricity generated in Vermont and 35 percent of the electricity consumed in the state. The plant’s capacity factor also exceeded 80 percent over its lifetime – more than double the capacity factor of the most efficient solar or wind plant in the United States. The plant’s final operating cycle, which ended on December 29, 2014, was the culmination of 633 days and nights of continuous operation.(i)
