US electricity from nuclear, 2001 to 2025
US electricity from nuclear stood at 784,781 in 2025, up 0.4% on the previous period.
United States generated 784,781 gigawatt hours of electricity from nuclear in 2025, up 0.4 percent on the year before. The window runs from 2001, when the figure was 768,826.
How it is measured
The series counts net generation, electricity actually delivered to the grid, from utility-scale plants of one megawatt and larger, across electric utilities, independent producers, and industrial generators. It is collected on the Energy Information Administration's Form EIA-923, the survey behind the Electric Power Monthly, reported as thousands of megawatt hours and shown here as gigawatt hours summed to years. Small-scale rooftop solar is estimated separately and is not included in series like this one.
What the curve shows
Generation data dates the energy transition more precisely than any announcement: what a grid actually runs on is here, year by year. Over the window it has ranged between 763,733 GWh (2003) and 809,409 (2019), steadier than the fuels changing around it.
