Exelon Generation is the leading competitive power generator in the nation, with owned generating assets totaling nearly 35,000 megawatts including 19,165 megawatts of clean nuclear energy in 22 units in Illinois, Pennsylvania, Maryland, New Jersey and New York; and 15,566 megawatts of non-nuclear generation, including (in order of megawatt capacity) natural gas, coal, hydro, oil, wind, solar and landfill gas.

The merger expanded Exelon Nuclear's fleet to include a majority share of Constellation Energy Nuclear Group (CENG), which operates Calvert Cliffs in Maryland, and R.E. Ginna and Nine Mile Point in New York. CENG is a joint venture with Electricite de France.

fleet provided more than 40 million megawatt-hours of reliable generation
