TrAIL is a 500-kV transmission line that was proposed by Dominion and Allegheny Power in 2007 and approved to be built in 2008. The line runs from southwest Pennsylvania, through West Virginia, ultimately terminating in Loudoun County, Virginia.
(The following text was written prior to approval of the TrAIL Line)
The 500-kV transmission line proposed by Dominion Virginia Power and Allegheny Power (through their subsidiary TrAILCo) would begin in Western Pennsylvania, cross through West Virginia, and end in Loudoun County, Virginia. In Virginia it would pass through the Meadow Brook Substation in Frederick County on its way to the Arcola Substation in Loudoun County.
The 10-16 story-tall transmission line would cut through private land, public open space, neighborhoods, historic sites, historic districts, magnificent viewsheds and a high concentration of conservation easements. In Virginia alone the transmission line would impact Frederick, Warren, Rappahannock, Culpeper, Fauquier, Prince William and Loudoun Counties. In addition, approval of the transmission line would lead to increasing reliance on remote coal-fired power plants in the Ohio River Valley with continuing or increasing transmission congestion, transmission losses and environmental damage.
