Transmission Lines

PATH Line Information

The PATH 765-kV transmission line was a partnership between American Electric Power and Allegheny Power. The line would have started near the Amos coal plant in West Virginia, traveling northeast through parts of Maryland and Virginia.

The Death Knell for PATH? Only time will tell.

On Feb. 28, 2011, the regional electric grid manager, PJM, issued a statement saying that it has ordered development of the PATH transmission line to halt.


On January 10, 2011 the Virginia State Corporation Commission (SCC) denied PATH’s motion to delay hearings on its 765-kV coal-by-wire transmission line.  In December, PATH had told the SCC that new information from PJM, the regional transmission organization charged with overseeing the electric grid in 13 states, had projected lower than expected electricity demand in the years to come, and that they needed additional time to evaluate the new numbers.  This request came just two months after they had told the SCC that they had all of the information necessary to proceed.

The following text was sent out via email alert on 07/14/2010:

It looks like PATH is gearing up for a second attempt at getting their transmission line approved and sited across three states. In June, PJM reaffirmed the "need" for PATH, and in early July, PATH submitted new testimony in West Virginia. We expect a new application to be submitted in Virginia and Maryland soon.

There are also scoping hearings being held by the National Parks Service, the U.S. Forest Service and the U.S. Army Corps of Engineers on July 19, 20, 21 and 22 to take public comment to help develop the scope of the federal review on the impact of the PATH project.

The Potomac Appalachian Transmission Highline (PATH) is a proposed $1.8 billion 200-plus mile long 765 kV extra high voltage electric transmission line linking the Amos substation (located adjacent to the nearly forty year old 2,933 MW coal-fired John E. Amos Power Plant located in western West Virginia) with a new substation proposed to be built in Frederick County, Maryland. PATH has been recommended by PJM Interconnection, the regional transmission organization. PJM is a consortium of power companies, transmission companies and other interested utilities. PATH is a joint project of AEP and Allegheny Power.
