History of Exelon Corporation

Exelon Corporation was created in October 2000 through the merger of PECO Energy Company, formed in 1902, and Unicom Corporation, the parent of Commonwealth Edison, formed in 1907. The merger combined two major utility companies with significant operational histories in the eastern and midwestern United States.

Following its formation, Exelon expanded through strategic acquisitions. In 2012, Exelon acquired Constellation Energy, significantly expanding its generation capacity. In 2016, Exelon completed its acquisition of Pepco Holdings, making it the largest regulated utility company in the United States by customer count and total revenue.

In February 2022, Exelon completed the corporate spin-off of Constellation Energy, its energy generation business, to focus on regulated utility operations. Constellation Energy became the largest operator of nuclear power plants in the United States and the largest non-governmental operator of nuclear power plants in the world.
