The filing incorporates the latest information and analyzes by regional transmission authority PJM Interconnection, which is recommending the construction of PATH by mid-2015.

In May 2009, Allegheny Energy affiliate PATH Allegheny Virginia Transmission Corporation filed its original Virginia application to build the 31-mile segment in Frederick, Clarke and Loudoun counties, but was authorized by the commission in January 2010 to withdraw its request to allow time for PJM’s review of system needs as part of its 2010 Regional Transmission Expansion Plan process.

Affiliates of AEP and Allegheny are seeking authorization to construct a 275-mile, 765kV transmission project extending from the Amos substation in Putnam County, West Virginia, to a proposed substation in Frederick County, Maryland.
