The United States remains the world’s largest producer of nuclear energy, with dozens of operating nuclear power plants supplying electricity to millions of homes and businesses across the country. Despite the rapid growth of renewable energy sources such as solar and wind, nuclear energy continues to play a vital role in maintaining a stable and low-carbon electricity supply. According to the latest data from the U.S. Energy Information Administration (EIA), the United States had 54 commercial nuclear power plants operating with 94 nuclear reactors as of early 2025. Together, these facilities have a combined electricity generation capacity of approximately 97 gigawatts (GW), making the U.S. the global leader in installed nuclear power capacity. Nuclear Energy Supplies Nearly One-Fifth of U.S. Electricity Nuclear energy remains one of the country’s most reliable sources of electricity. Unlike renewable energy sources that depend on weather conditions, nuclear reactors can generate electricity continuously throughout the year. The EIA estimates that nuclear power contributes around 19% of all electricity generated in the United States, helping reduce dependence on fossil fuels while supporting national energy security and climate goals. Today, 28 U.S. states operate commercial nuclear power plants, with every facility located within the continental United States. Illinois Leads U.S. Nuclear Power Generation Among all states, Illinois remains the nation’s largest producer of nuclear-generated electricity. The state operates six nuclear power plants containing 11 reactors, producing approximately 7,642 megawatt-hours (MWh) of electricity during the reported period—more than half of Illinois’ overall electricity production. Other major nuclear-producing states include: These states continue to rely heavily on nuclear energy as part of their overall electricity generation strategy. Plant Vogtle Is America’s Largest Nuclear Power Facility Located in Georgia, Plant Vogtle currently holds the distinction of being the largest nuclear power plant in the United States. Originally commissioned in 1987, the facility significantly expanded after its fourth reactor entered commercial operation in March 2024. The expansion increased the station’s total generating capacity to roughly 4,800 megawatts, allowing Plant Vogtle to surpass Arizona’s Palo Verde Nuclear Generating Station in overall capacity. The completion of Vogtle’s newest reactors marked one of the most significant developments in the U.S. nuclear industry in decades, reflecting renewed investment in long-term, carbon-free electricity generation. How the United States Compares With Other Countries Although the United States leads the world in both nuclear generating capacity and the number of operating commercial nuclear plants, several other countries continue to invest heavily in nuclear energy. Based on data from the International Atomic Energy Agency (IAEA), the leading nuclear power nations after the United States include: France operates 57 reactors with approximately 63 GW of generating capacity, although maintenance issues and unexpected shutdowns have periodically reduced its output in recent years. China currently operates 58 reactors capable of producing about 56.45 GW of electricity. The country’s nuclear sector is expected to expand further following government approval for additional reactor construction, reinforcing China’s long-term strategy to diversify its energy mix. Russia and South Korea continue to maintain substantial nuclear generation capacity, although both trail significantly behind the world’s top three producers. Japan Still Hosts the World’s Largest Nuclear Plant Interestingly, the world’s largest individual nuclear power station is located in Japan. The Kashiwazaki-Kariwa Nuclear Power Plant remains the largest by installed capacity. However, the facility has faced repeated operational challenges over the years, including safety reviews and temporary shutdowns, leaving uncertainty about its long-term operating future. Why Nuclear Power Remains Important Global demand for electricity continues to increase while governments pursue ambitious carbon-reduction targets. As a result, nuclear power is receiving renewed attention as an energy source capable of delivering large amounts of electricity without direct greenhouse gas emissions during operation. Supporters argue that nuclear energy provides dependable, around-the-clock power that complements renewable energy. Critics, however, continue to raise concerns over radioactive waste management, high construction costs, and plant safety. The future of nuclear energy will likely depend on continued technological advancements, regulatory oversight, investment in modern reactors, and each country’s long-term energy policy. As nations seek cleaner energy solutions while maintaining reliable electricity supplies, nuclear power is expected to remain a significant component of the global energy landscape for years to come.
