Dresden Clean Energy Center

Nuclear: An Ideal Foundation for Our Clean Energy Future

Dresden Clean Energy Center’s two nuclear reactors in Morris, Illinois, can generate up to 1,845 megawatts (MW) of clean, carbon-free energy, enough  electricity to power the equivalent of nearly 1.4 million homes. The site is also home to the nation’s first full-scale, privately financed nuclear plant, which was retired in 1978 and has been designated a Nuclear Historic Landmark.

U.S. nuclear energy facilities are initially licensed to operate for 40 years and a Nuclear Regulatory Commission (NRC) rule allows licensees to apply for initial and subsequent license renewals of up to 20 years each after the initial 40-year term. The NRC approved initial license renewal for Dresden on October 28, 2004, authorizing operation for Unit 1 through December 22, 2029 and for Unit 2 through January 12, 2031. The company intends to apply for subsequent license renewal in 2024.

Safety is Constellation’s first and highest obligation. Nuclear power plants are among the best-protected private sector facilities in America, with monitoring and inspections by plant owners, local officials, and the federal government.
