US Fleet by Operator

Who actually owns the US reactor fleet, by gross capacity and by unit count, with pending restarts stacked on top. Constellation runs a fifth of it; the rest is mostly regulated utilities holding one to a handful of units each.

US Capacity Factor

Annual fleet-weighted average for the US nuclear fleet 2000-2025. The US runs ~89-93% capacity factor consistently, the highest of any generation type (gas ~57%, wind ~33%, solar ~25%).

US Nuclear Fleet Capacity Factor by Operator

Annual capacity factor by US nuclear operator, 2015-2024. Top operators (CEG, TLN) routinely cross 95%; the fleet-weighted average is overlaid as a dashed benchmark.

US Restarts and Retirements

US nuclear capacity changes 2013 to 2026: the 2010s wave of retirements (red) versus restarts and new builds like Vogtle 3+4 (green), sized by MWe.
