The Most Recently Built Nuclear Power Plants in the United States

Methodology

To identify the newest nuclear power plants in the U.S., 24/7 Wall St. reviewed the start dates of commercial operation for nuclear reactors in the United States, using data compiled by the Nuclear Regulatory Commission. We only considered nuclear power plants in which the oldest operational nuclear reactor began generating commercial power after Jan. 1, 1980. We then ranked those plants based on how long their newest reactor has been generating commercial electricity. 

To compare each power plant’s electricity production capacity, we summed each plant’s reactors’ megawatt electricity (MWe). 

Plant names and data are as identified on their licenses as of August 2022. The next printed update will be in September 2022.
