The Virginia State Corporation Commission (SCC) is seeking public comment on a Potomac Edison proposal to rebuild more than six miles of 138-kV transmission line in the northern Shenandoah Valley.
On July 21, the FirstEnergy (NYSE:FE) company filed an application for approval and certification for transmission facilities in connection with the proposed rebuild of the Double Toll Gate-Riverton 138 kV Transmission Line.
The line is located between the existing Double Toll Gate and Riverton substations. The Double Toll Gate substation is located in Clarke County, Va., and the Riverton substation is in Warren County.
The line is approximately 7.07 miles in length, of which 6.3 miles are proposed to be rebuilt. The line generally parallels State Route 522 to the west. The Riverton substation is located about 3 miles north of Front Royal, Va.
The estimated cost of the rebuild project is approximately $6.1m.
The line is located less than 70 miles from Washington, D.C. Potomac Edison states the Double Toll Gate-Riverton Line is a critical component of the electric transmission grid that serves Virginia.
Potomac Edison proposes to replace 52 of the 60 structures comprising the Double Toll Gate-Riverton Line. The company expects the new structures will be installed in approximately the same locations as the existing poles. The company says the existing structures average approximately 70 feet in height.
Potomac Edison proposes approximate structure heights ranging between 70 feet and 90 feet, which are subject to change based on final engineering design. The project will use a combination of single, two pole, and three pole wood structures.
The company anticipates an in-service date for the proposed rebuild project of June 1, 2017, and states that it will need approximately three to four months for construction. The proposed route is an existing northeast to southwest.
The company anticipates that less than a quarter-acre of tree clearing will be required in an area adjacent to the existing right of way to accommodate a work area.
Potomac Edison and its legal counsel, Hunton &Williams LLP, published a map and descriptions of the project in the Sept. 8 edition of the Warren Sentinel, a general circulation newspaper in Front Royal.
Interested parties can submit comments electronically on or before Oct. 19. All comments shall refer to Case No. PUE-2016-00077.
