 US Nuclear Power Plants Set Average Capacity Factor Record in 2015

U.S. nuclear power facilities operated at a record high level of reliability in 2015, according to preliminary estimates from the Nuclear Energy Institute (NEI).
NEI said 99 operating power plants in 30 states posted an estimated average capacity factor of 91.9 percent, based on preliminary 2015 data. That number surpasses the industry’s prior record set in 2007 by one-tenth of a percentage point. Capacity factor measures the total electricity generated as a percentage of potential generation for the entire year.
Electricity production from nuclear planta last year was an estimated 797.9 billion kilowatt-hours (kWh). The industry’s record was in 2010 when 104 reactors produced 806.9 billion kwh of electricity while posting an average capacity factor of 90.9 percent.
The amount of electricity generated last year surpassed the amount produced in 2014, though there was one less power plant with the closure of the Vermont Yankee nuclear plant.
“The 2015 data confirm yet again what a tremendous asset nuclear energy technology is,” said NEI Chief Nuclear Officer Anthony Pietrangelo. “U.S. nuclear power plants continue to operate at exceptional levels of safety and reliability, while generating affordable electricity that consumers and our economy rely on. This is due to the hard work and dedication of the highly skilled men and women who work at these facilities and the reactor vendors and suppliers who provide support services.”
Final 2015 data will be available in about two months.
