Pepco Holdings, Inc. is a holding company incorporated in February 2001 for the purpose of affecting the acquisition of Conectiv Power Delivery by Potomac Electric Power Company . The acquisition was completed on August 1, 2002 at which time Pepco and Conectiv became wholly owned subsidiaries of PHI. Conectiv itself had been formed in 1998 to be the holding company of Delmarva Power & Light Company and Atlantic City Electric Company in connection with the combination of DPL and ACE. In 2005, PHI resumed the use of the Delmarva Power and ACE brands for purposes of operations, with the result that Conectiv Energy was the only remaining Conectiv brand and was restricted for PHI's energy production facilities. read more
