Dominion Takes Historic Project by Storm: Crucial rebuild strengthens electric grid

摘要

Four years ago, Dominion Virginia Power embarked on the single-largest transmission project in its 100-year history. Important to the regional electric grid, the innovative project focused on rebuilding a 96.4-mile (155-km) line that crosses three states. Dominion built North America's first 500-kV electric transmission loop in the 1960s. The 500-kV Mount Storm-Doubs (MSD) line is the major east-west segment along the northern corridor of that 350-mile (560-km) system, spanning six counties from Grant County, West Virginia, east to the border of northern Virginia, then crossing 3 miles (4.8 km) into Maryland, in FirstEnergy's service territory. The rest of the loop travels south toward Richmond, Virginia, west toward West Virginia and north toward the Mount Storm power station, Dominion's largest coal-fired power station.
