Exelon, the largest American producer of carbon-free energy, completed the acquisition of a 50% stake in Constellation Energy Nuclear Group, a firm which generates and distributes nuclear energy, from EDF, a French electric utility company, for $885m. "Since Exelon Generation took over operations, we have created value for both Exelon and EDF by integrating the three plants into the nation’s largest and best-run nuclear fleet. Leveraging the Exelon management model, we’ve improved overall fleet performance and efficiency while reducing costs in a challenging market environment. We have worked collaboratively with EDF leadership as co-owners of these three nuclear plants and look forward to partnering with them in a productive process to purchase their ownership stake,” Chris Crane, Exelon President, and CEO.
