The National Park Service approved construction October 2 through 4.5 miles of national park lands for a 146-mile, high-voltage transmission project that utilities claim is needed to reduce transmission congestion and lower electricity prices in the mid-Atlantic. Disagreements over routing for the 500-kv Susquehanna-Roseland transmission project, which would upgrade an existing line between Pennsylvania and New Jersey, has stalled the project for three years. The project is one of seven major transmission projects designated as high priorities in October 2011 by the Rapid Response Team for Transmission.
