The capacity operating hours of a nuclear power plant are equal to the quotient from the total capacity in a period of time and the maximum capacity of the plant. For example the capacity operating hours of various power plants for public supply in Germany in 2009 amounted to:

  • Photovoltaic: 890 h/a
  • Pumped storage hydroelectric:  950 h/a
  • Wind: 1,520 h/a
  • Mineral oil: 1,870 h/a
  • Natural gas: 3,150 h/a
  • Run-of-river hydroelectric: 3,530 h/a
  • Hard coal: 3,580 h/a
  • Biomass: 5,000 h/a
  • Lignite: 6,610 h/a
  • Nuclear: 7,710 h/a
