One hundred U.S. nuclear power plants generated electricity at a capacity factor of just under 92 percent in 2014, according to statistics from the Nuclear Energy Institute (NEI).
The average capacity factor of 91.9 percent surpasses the 2007 record by one-tenth of a percentage point. Capacity factor measures total electricity generated as a percentage of year-round potential generation, NEI said. Actual electricity production from nuclear power plants was the sixth-highest ever, at an estimated 798.4 billion kwh. The record is from 2010, when 104 reactors produced 806.9 billion kwh of electricity and an average capacity factor of 90.9 percent.
The South Texas Project 2 led the top 10 nuclear power plants in both capacity factor and electricity generation in 2014. Rounding out the list for capacity factor is Three Mile Island 1, Surry 1, Braidwood 1, Peach Bottom 3, Farley 1, Oconee 2, St. Lucie 1, Hope Creek 1, and Palo Verde 3. The remaining top nuclear plants for generation are Palo Verde 3, Braidwood 1, Perry 1, Palo Verde 2, Palo Verde 2, Susquehanna 2, Grand Gulf 1, Seabrook 1, and Peach Bottom 3.
