COLUMBUS, Ohio, and GREENSBURG, Pa., June 18, 2010 – American Electric Power (NYSE: AEP) and Allegheny Energy, Inc. (NYSE: AYE) today announced that new studies by independent grid operator PJM Interconnection recommend construction of the Potomac-Appalachian Transmission Highline (PATH) as the most effective solution to address numerous electric reliability concerns forecast for the Mid-Atlantic region.

The latest analyses, conducted as part of PJM’s 2010 Regional Transmission Expansion Plan (RTEP), are consistent with previous studies since 2007 identifying PATH as the preferred solution for resolving issues on the region’s transmission grid. Based on the findings announced today, PJM is directing that PATH be placed into service by June 1, 2015, at the latest.

“All analysis to date indicates that the PATH project remains the most robust and effective means to ensure the long-term reliability of the PJM grid,” said Steven R. Herling, Vice President of Planning, PJM.

The PATH project was evaluated against six alternatives and found to be the most comprehensive solution to resolve numerous voltage-related issues and line overloads that are projected to begin in mid-2015. Among the other alternatives examined, PATH is the recommended solution that resolves the majority of the projected reliability issues within PJM’s 15-year planning period.

Taking into account a thorough regulatory review as well as the time required to complete construction of the line, the PATH companies will continue to move forward quickly with the project. The new data will be incorporated into the existing applications for regulatory approval in Maryland and West Virginia, as well as in a new application to be filed in Virginia in the third quarter.

PATH is a joint venture between Allegheny Energy and AEP to construct a 275-mile, 765-kilovolt (kV) transmission project extending from the Amos substation in Putnam County, W.Va., to a proposed substation in Frederick County, Md.
