The Loudoun to New Road project is a 4-mile, double-circuit 230 kV transmission line originating at Loudoun Substation and terminating at the New Road Substation in Loudoun County. The project involves replacing existing structures, adding a second circuit and increasing the voltage of a portion of the line from 115 kilovolts to 230 kilovolts — all within the boundaries of the existing right-of-way. The project was estimated to cost $13 million and was placed into service May 2013.
