Arlington: Rosslyn 230 kV Line and Substation Upgrades

On a busy block in the downtown Clarendon area, Dominion has recently completed work to upgrade a critical substation that improves electric reliability for homes and businesses throughout Arlington.

Because of this facility's highly visible location and frontage on both Fairfax Drive and Wilson Boulevard, Dominion is working with Arlington County to make the substation more harmonious with its immediate surroundings.

An invited list of artists and designers presented their work to representatives from Arlington County, Dominion and the local community. The successful bidder will produce a final concept for a perimeter treatment later this year, with the project's anticipated completion by Fall 2011.

Project Milestones

• Dominion redesigned and rebuilt the substation located at Fairfax Drive and Wilson Boulevard (3245 Wilson Boulevard). The rebuilt substation will include a new containment wall that complements the surrounding environment. A working group that includes community leaders is guiding the design of this wall.
• Dominion installed a 230 kV underground line from the existing substation at 1033 Nelson Street to the rebuilt substation at 3245 Wilson Boulevard. This line is approximately 2200 feet (0.4 mile±) long.
• Dominion constructed 69 kV underground lines from both the Nelson Street and Wilson Boulevard substations to the Rosslyn Substation at 1850 N. Moore Street. These lines are a little over 2.5 miles long.
