May nuclear generation by state report
Last updated May 2, 2023
Nuclear energy remains a major power source in the U.S. Nuclear power accounts for 19.6% of the total electricity generated in the country, according to the May Nuclear Energy Report. This report is based on the latest U.S. Energy Information Administration data, which shows nuclear generation by state from February 2023.
Which state generates the largest amount of energy from nuclear sources? The EIA says that in February, it was Illinois, with 7,321 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.
