      TOTAL 101,004 806,968,301  
1 Summer Capacity (Net): The maximum output (excluding electricity used for station's internal operations, expressed in Megawatts (electricity). Note that nuclear power can also be expressed in Megawatts (thermal).
2 Megawatt hours.
3 Capacity Factor: The ratio of power actually generated to the maximum potential generation expressed as a percent. The factor is calculated by multiplying the summer capacity by the number of hours in a day (24) by the number of days in a year (365 or 366). That total is then divided into the amount of actual generation and multiplied by 100 to get a percent.
PWR = Pressurized light Water Reactor
BWR = Boiling Water Reactor
