Total U.S. nuclear plant availability dipped early Jan. 31 to 95.45%, down from 96.04% on Jan. 30 but still much higher than the 92.00% reported on the same day a year ago.

Pulling down U.S. output was a curtailment at NextEra Energy Inc.'s St. Lucie 1 plant in Florida. The unit saw production fall from 100% on Jan. 30 to 30% early Jan. 31.

In addition, Entergy Corp.'s Grand Gulf 1 in Mississippi was at 9% early Jan. 31, up from 1% the day prior. The unit was recently restarted following a maintenance outage that began Sept. 8, 2016.
