Calvert Cliffs Clean Energy Center

Nuclear: An Ideal Foundation for Our Clean Energy Future 

Located in Lusby, Maryland, Calvert Cliffs Clean Energy Center’s two nuclear reactors can produce up to 1,790 megawatts (MW) of clean, carbon-free  energy, enough electricity to power the equivalent of more than 1.3 million homes. The site is home to a well-cared-for Champion Chestnut Oak, which is listed in the American Forests national register.

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 on March 23, 2000, authorizing Calvert Cliffs Unit 1 to operate through 2034 and Unit 2 to operate through 2036.

Safety is Constellation’s first and most critical 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.
