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.

Calvert Cliffs Clean Energy Center has been part of Lusby, Maryland and its surrounding communities for more than 40 years. We provide hundreds of well-paying jobs and millions of dollars in economic support, including about $22.8 million in taxes annually for schools, roads and other public services.
