The request will allow the Trans-Allegheny Interstate Line Company (Trailco) to pursue a more collaborative process to explore whether there are new and creative alternatives to the proposed 36-mile portion of the 500kV line in Greene and Washington counties, and related facilities.

The company’s motion also requests that the commission approve a 1.2-mile section of a 500kV line extending from the West Virginia border to a new substation in Greene County, Pennsylvania, known as 502 Junction.

This portion of the project reportedly addresses critical reliability concerns that could adversely impact the mid-Atlantic region, including Pennsylvania electric customers, as early as 2011.
