January nuclear generation by state report
Last updated January 9, 2023
Nuclear energy remains a major source of power in the U.S. Nuclear power accounts for 18.8% of total electricity generated in the U.S., according to the January Nuclear Energy Report. The report is based on the latest data from the U.S. Energy Information Administration, which shows nuclear generation by state from October 2022.
Which state generates the largest amount of energy from nuclear sources? The EIA says that in January, it was Illinois, with 8,060 thousand megawatt-hours. Alaska, Colorado, Delaware, Hawaii, Idaho, Indiana, Iowa, Kentucky, Maine, Massachusetts, Montana, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, Rhode Island, South Dakota, Utah, Vermont, West Virginia, and Wyoming don’t generate a significant amount of nuclear energy, so they will not be included in the findings below.
