To ensure carbon free energy for decades to come, Constellation submitted license renewal applications to and received extension approvals from the U.S. Nuclear Regulatory Commission (NRC) and the Federal Energy Regulatory Commission (FERC) for several of our generation sites. We are 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. This 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.
Many of our nuclear generation facilities have already completed license renewal, guaranteeing decades of zero-carbon power generation.
FERC License Renewals for Non-Nuclear Energy Sites
Preserving our virtually emissions-free generating capacity and electrical output is important for the nation’s environmental goals and to support businesses, education, and other public services in local communities. FERC licenses are typically issued for a period of 30 to 50 years.

Delta, Pennsylvania
Peach Bottom Atomic Power Station is a two-unit nuclear generation facility located on the west bank of the Conowingo Pond (Susquehanna River) in Delta, Pennsylvania. Peach Bottom is co-owned by Constellation and Public Service and Gas of New Jersey. Constellation operates the two of three units at Peach Bottom that are currently in operation. Both operating units are boiling water reactors that generate a combined total of 2,770 megawatts (MW) of electricity. These units began commercial operation in 1974 and were granted a 20-year extension by the Nuclear Regulatory Commission (NRC) on March 6, 2020. This extension authorizes the plant’s two reactors to continue generating carbon-free electricity for more than 2.7 million homes and businesses through 2054. If Peach Bottom continues to run through that period, it is estimated that its clean energy production would avoid more than 536 million tons of carbon from entering the atmosphere. That amount of carbon avoidance is equivalent to removing 3.3 million cars from the roadway every year for 34 years.
Cordova, Illinois
Constellation submitted a license renewal application for this facility to the U.S. Nuclear Regulatory Commission (NRC), which was approved on October 28, 2004. With license renewal complete, Quad Cities Generating Station Units 1 and 2 are licensed through 2032.
