About this ranking
Net electricity generated by nuclear power plants in the year, in terawatt hours, as reported to the U.S. Energy Information Administration on Form EIA-923.
United States and its states only. States without a nuclear plant have no value; a state's series stops when its last reactor closes.
Every value in the ranking comes from the same publisher and the same period, so the states are compared on one definition. 3 states with data in other periods have no value for 2023 and are left out rather than filled from another source. Equal values share a rank.
