License Renewals

​License renewals mean clean, zero-carbon energy well into the future.

Exelon Nuclear has submitted license renewal applications for several of our generation sites to the U.S. Nuclear Regulatory Commission (NRC) and the Federal Energy Regulatory Commission (FERC). We’re committed to producing clean, safe and reliable energy for American homes and businesses for decades to come.

NRC License Renewals for nuclear energy sites.

Nuclear energy plants in the United States are licensed to operate for 40 years. The 40-year term is based on the amortization period used by electric utility companies for capital investments; it’s not based on safety, technical or environmental issues. The Atomic Energy Act of 1954 permits nuclear plants to renew their operating licenses.

Some of our facilities have already completed license renewal, guaranteeing decades of zero-carbon power generation. Learn about them here:

FERC License Renewals for Exelon’s non-nuclear sites.

Preserving our virtually emissions-free generating capacity and electrical output is important for the nation’s environmental goals, and life in local communities. FERC licenses are typically issued for a period of 30 to 50 years.
