Pepco Holings, Inc. (or "PHI" NYSE: POM) is a holding company incorporated in February of 2001 for the purpose of effecting the acquisition of Conectiv Power Delivery by Potomac Electric Power Company (better known as "Pepco"). 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 (DPL, better known as "Delmarva Power") and Atlantic City Electric Company (ACE) in connection with the combination of DPL and ACE. In 2005, PHI resumed the use of the DPL and ACE entity names 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.
