Work Continues on Design, Route and Environmental Studies

WASHINGTON--Pepco Holdings, Inc. (NYSE: POM) today said that a hearing examiner for the Maryland Public Service Commission granted its request to suspend until June 2010 the procedural schedule on its application to build the Mid-Atlantic Power Pathway (MAPP), a high-voltage transmission line to the Delmarva Peninsula.

The company asked for the delay last week pending completion of a study to re-evaluate the region's over-all transmission needs by PJM Interconnection, the independent regional power grid operator. MAPP Project Manager Bob Jubic said that while no formal proceedings will be held until that time, work would continue to define the line's 150-mile route and to complete environmental studies.

The Office of People's Counsel immediately filed a motion to rescind the hearing examiner's order and instead schedule a hearing.
