History

Exelon Corporation was created as the result of a merger between PECO Energy Company and the Unicom Corporation in October 2000. Unicom was based in Chicago and the city became the home of the new entity. The merger was overseen by the CEO of Unicom, John Rowe who joined the corporation in 1998 and went on to lead the newly-formed Exelon until 2012, becoming the nation's longest-serving utility executive. Under Rowe, Exelon explored a number of mergers and acquisitions. On June 30, 2005, the

The merger sat pending in front of the NJBPU for nineteen months before Exelon concluded that they were fighting a losing battle. On April 28, 2011, Exelon announced a merger with Constellation Energy for $7.9 billion with the combined company owning more than 34 gigawatts of power generation (55 percent nuclear, 24 percent natural gas, 8 percent renewable including hydro, 7 percent oil and 6 percent coal). The merger was completed on March 12, 2012. In 2012, when announcing the cancellation of new nuclear construction for Victoria County Station, Texas, Exelon stated that economic and market conditions, especially low natural gas prices, made the "construction of new merchant nuclear power plants in competitive markets uneconomical now and for the foreseeable future". In 2008, Christopher Crane was named CEO following Rowe's retirement and the completion of the merger with Constellation Energy. Exelon announced the proposed purchase of Pepco Holdings, Inc on April 30, 2014, for $6.8 billion in an all-cash transaction. The merger was rejected by the

On March 23, 2016, the merger was approved by the Washington DC Public Service Commission, under a revised set of terms. The merger was completed later that day making Exelon the largest regulated utility in the United States by customer count and total revenue. On February 2, 2022, Exelon completed the separation of its energy generation business to Constellation Energy.
