In October 2000, two distinct utility companies joined forces to create Exelon Corporation. PECO Energy Company and Unicom Corporation merged in a move that reshaped the American power landscape. The new entity took its headquarters in Chicago, Illinois, where Unicom had been based since 1907. John Rowe served as the CEO of Unicom before the merger and led the newly formed company until 2012. He became the nation's longest-serving utility executive during his tenure. This combination brought together six regulated utilities under one roof. Atlantic City Electric serves New Jersey with 545,000 electric customers. Baltimore Gas and Electric operates across Maryland with over 1.25 million electric customers. Commonwealth Edison handles electricity for 4 million people in Illinois. Delmarva Power and Light covers Delaware and parts of Maryland with 515,000 electric customers. Pepco provides service to Washington D.C. and Maryland with 842,000 electric customers. PECO Energy Company itself serves eastern Pennsylvania with 1.6 million electric customers.
Strategic Moves And Corporate Spin-Offs
Exelon made several major corporate decisions between 2005 and 2022. On the 31st of July 2005, the Federal Energy Regulatory Commission approved a merger with Public Service Enterprise Group. That agreement lasted only 18 months before both companies terminated it due to pressure from public interest groups like New Jersey Citizen Action. The company acquired Constellation Energy on the 12th of March 2012. This purchase gave Exelon control of more than 34 gigawatts of power generation capacity. Over half of that capacity came from nuclear sources. In April 2014, Exelon announced plans to buy Pepco Holdings for $6.8 billion. Community groups and D.C. Mayor Muriel Bowser opposed the deal. The District of Columbia Public Service Commission initially rejected the merger in August 2015. After appeals and concessions, regulators finally approved the transaction on the 23rd of March 2016. Two years later, on the 2nd of February 2022, Exelon completed the spin-off of its energy generation business as Constellation Energy. Constellation became the largest operator of nuclear power plants in the United States.
