NEI reports that U.S. nuclear fleet had 84.5% capacity factor in November

The U.S. nuclear fleet’s average estimated capacity factor in November 2015 was 84.5%, which was down from the 91.2% figure recorded in in November 2014, according to recent data from the Nuclear Energy Institute (NEI).

Estimated U.S. nuclear generation in November 2015 was 60.1 billion kWh, compared to 65.1 billion kWh in November 2014.

In its Nuclear Performance report for November, NEI seems to attribute the drop-off to the timing of many nuclear plant refueling outages. “Thirty reactors refueled this fall, compared to 24 in fall 2014,” NEI said in the monthly update.

In the period Jan. 1 to Nov. 30, 2015, the fleet’s average estimated capacity factor was 91.8%, above where it was for the same period in either 2014 or 2013, NEI said.
