The U.S. Department of Justice (DOJ) has cleared the way for the merger of Exelon Corp. and Constellation Energy.

The DOJ's Antitrust Division filed court papers Dec. 21 seeking approval by the U.S. District Court for the District of Columbia with regard to the merger. These papers detail the conditions agreed to by DOJ and Exelon and Constellation for the companies to merge. Upon the court's order adopting the proposed conditions, Exelon and Constellation will be free to close the transaction, pending other regulatory approvals.

The merger has been approved by the New York Public Service Commission, the Public Utility Commission of Texas and shareholders of Exelon and Constellation. It also requires regulatory approvals by FERC, the Nuclear Regulatory Commission and the Maryland Public Service Commission.

The Exelon-Constellation merger will combine Exelon's environmentally advantaged generation fleet with Constellation Energy's customer-facing businesses.
