The D.C. Public Service Commission denied Exelon’s proposed $6.4 billion takeover of Pepco Holdings, saying it was not in the best interests of the ratepayers. In a letter to the U.S. Department of Justice in February 2015, the AAI urged the Antitrust Division to seek remedies to the proposed merger of electric utilities Exelon and Pepco. The letter lays out the rationale for why the merger was likely to harm competition and consumers and why antitrust remedies are compatible with the Federal Energy Regulatory Commission’s access policies.
