This project involves building a new transmission line and substation facilities in the Dulles community. The new line is needed due to rapid growth in electrical demand, particularly by the commercial/high-tech sector in Loudoun County.
NOTICE OF AVAILABILITY - Washington Dulles International Airport finding of no significant impact for Poland Road 230-KV Transmission and Substation Project
- Maintains federal and company standards while addressing the rapid commercial/high tech sector growth in a prudent and safe manner
- Provides needed electrical capacity to maintain overall reliability for the community
- Supports continued economic development in the area
The proposed project will support rapid and continued growth in Loudoun County. In particular, new high-tech sector business growth proposed in the Dulles area will draw enough electricity that it is projected to exceed the capabilities of our distribution system in the coming years. This means that solving this issue by adding additional capacity at electric transmission-level voltage is required to address the forecasted increase in power demand.
On May 20, 2015, this project was filed with the Virginia State Corporation Commission .
- Approximate total line length: 4 +/- miles
- Right of way: New right of way corridor will be 100 feet wide
- Typical structure description: single pole structure (galvanized steel)
We are committed to reasonably minimizing the impact on communities, historic areas, and the environment by working with local residents and public officials in the study area to identify constraints and opportunities for locating new facilities. Community input is an important part of our routing analysis. We incorporate the input as we consider how projects can best meet the energy needs of our customers, the impact the projects will have on the transmission grid, costs and Virginia State Corporation Commission (SCC) requirements.
Any feedback we receive will be considered and will help us prepare a stronger and more thorough application for the SCC to review.
Outreach included letters to neighboring property owners, local newspaper ads, and public meetings (an open house informational meeting was help April 29, 2015 at the Little River Elementary School).

The SCC requires us to present the route that meets the need electrically, while balancing impacts and cost to ratepayers, with potential alternatives to compare against. We will prepare an exhaustive routing study that looks at all routing options available, taking into consideration a variety of constraints, such as proximity to residential homes, impact to historical and cultural assets, environmental impacts, just to name a few. Various route options were explored within a specific “study area.” That analysis has resulted in a set of preliminary routes options for initial review and feedback.
After receiving public input, Dominion Energy submitted one Proposed Route with alternatives that have been considered, as per SCC requirements. Ultimately, the SCC will make the final determination of the route location that reasonably minimizes impacts.

SCC Approval Process
The State Corporation Commission (SCC) is responsible for determining the need, route and environmental impact of transmission lines in Virginia.
Dominion Energy submitted its application regarding the Poland Road project on May 20, 2015. Documents related to the case are made available to the public on the SCC Docket Search section of the SCC web site, in the "Search Cases" section (enter case number PUE-2015-00053). In addition, interested parties may also comment directly to the SCC by sending an email to email@example.com.
