History
Exelon Corporation was created in October 2000 by the merger between PECO Energy Company, formed in 1902, and Unicom Corporation, the parent of
Commonwealth Edison, formed in 1907.
Unicom was based in Chicago and the city became the headquarters of the new entity. The merger was overseen by the CEO of Unicom, John Rowe, who joined the corporation in 1998 and led the newly formed Exelon until 2012, becoming the nation's longest-serving utility executive.

utility; however, after 18 months, the two companies terminated the agreement due to pressure put on the
New Jersey Board of Public Utilities by public interest groups, including New Jersey Citizen Action.
On March 12, 2012, Exelon acquired
Constellation Energy, with the combined company owning more than 34 gigawatts of power generation (55% nuclear, 24% natural gas, 8% renewable including hydro, 7% oil and 6% coal).
Exelon announced the proposed purchase of
Pepco Holdings on April 30, 2014, for $6.8 billion in an all-cash transaction. The merger faced stiff opposition from community groups and D.C. Mayor
Muriel Bowser. The merger was originally rejected by the
District of Columbia Public Service Commission in August 2015, though it was approved by other federal and state regulators. The companies appealed the decision. On March 23, 2016, the merger was finally approved by the
District of Columbia Public Service Commission after the company made concessions and the merger was completed, making Exelon the largest regulated utility in the United States by customer count and total revenue.
On February 2, 2022, Exelon completed the

Exelon and Illinois state officials waited for four years until 2006 before disclosing that Exelon's

Peach Bottom Nuclear Generating Station, a two-reactor nuclear plant located in Delta, Pennsylvania, to sleep on the job. The incidents did not come to light until a videotape of the security guards was leaked to news media. As a result, Exelon terminated the security contract of the
Wackenhut security firm that had been involved and now operates its own in-house nuclear security force.
