Total U.S. nuclear plant availability took another step back early Jan. 25 to 94.79%, down from 95.39% on Jan. 24, but still much higher than the 91.55% level reported the same day in 2016.

Contributing to the decline was the loss of Southern Co.'s Hatch 1 plant in Georgia. The unit was offline early Jan. 25 after being curtailed to 38% the day prior. The reason for the shutdown is currently unknown.

In addition, PG&E Corp.'s Diablo Canyon 1 plant in California saw output drop from 94% on Jan. 24 to 55% early Jan. 25.

Conversely, Unit 2 of the Peach Bottom power plant in Pennsylvania, which is jointly owned by Exelon Corp. and Public Service Enterprise Group Inc., returned to full power early Jan. 25. The plant was at 90% the day prior.
