Overview & Project Description

The amount of load growth requires a new 230kV double circuit transmission line using existing transportation corridors where possible and requiring new right of way. The new line will extend to a new substation west of the Haymarket town limits.

The new substation, to be built on a shared commercial property, will accommodate future area growth. The combined efforts will provide Dominion Energy and eventually NOVEC, additional capacity to support continued economic development and improved reliability for the area.

  • Approximate total line length: 5.3 +/- miles (proposed project as filed)
  • Overhead/Underground Hybrid Option: includes 2.2 +/- miles of overhead line and 3.1 +/- miles of underground line
  • New Overhead right of way corridor will be 100’ feet wide
  • Structure Type: Single Shaft, Double Circuit, Average Height 112' - Typical structure comparison images (galvanized steel)
  • New Underground right of way corridor will be approximately 40' feet wide (an additional 10 feet of temporary right of way will be needed during construction)

Outreach has included letters to neighboring property owners, email updates, local newspaper ads and public meetings.


We strive to minimize the impacts of our new projects that require new right of way while being sensitive to the permanent change to the community we have an obligation to serve.

Route Maps

Dominion Energy considers a number of factors when studying options for routing new electric transmission lines. We evaluate a route’s constructability and operability while carefully weighing potential impacts on property owners, historic assets and the environment, to name a few. It is important that we study and present various alternatives in order to have a complete application for the SCC to consider, which must include a proposed route, as well as constructible alternative(s).

Ultimately, the SCC will make the final determination of the route location that reasonably minimizes impacts.

SCC Approval Process - Status Approved

On December 6, 2017, the Virginia State Corporation Commission remanded the case back to the Hearing Examiner to receive additional evidence and legal analysis on 1) the need for the transmission line; and 2) any additional route variations to the routes proposed in the record. This in effect paused the June 23, 2017, Final Order and earlier Interim Order, which approved Dominion Energy’s application, while these additional proceedings took place.

On June 12, 2018, the SCC issued its order reaffirming the need for the Haymarket transmission line. And on July 26, 2018, the SCC issued its final order approving the project along the I-66 Hybrid Route, including it in the underground transmission pilot program.

The State Corporation Commission (SCC) is responsible for verifying the need of a project and determining the route the project will follow.

Dominion Energy submitted its application regarding the Haymarket Project on November 6, 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-2015-00107). In addition, interested parties may also comment directly to the SCC by sending an email to sccinfo@scc.virginia.gov.

FAQs

Conservation measures, greater efficiency and demand-side management can reduce demand growth rates, but Dominion Energy does not expect these measures to be sufficient to eliminate the need altogether and is obligated to be prepared to satisfy the load requirements as they occur.
This project involves significant work to expand and upgrade the existing distribution system to help meet the immediate demand for electricity and better serve the area and its high-tech customers.

However, the transmission facilities are the only solution that will meet the projected electrical needs in the area in 2017 and beyond. There are no distribution upgrades that would resolve the long-term projected energy demands in the area.
Routing a linear facility such as a transmission line involves balancing many considerations. Dominion Energy and its consulting partner, Natural Resource Group (NRG), conduct a rigorous routing process and will establish several criteria to facilitate a comparison among potential routes if identified. The evaluation will include a quantitative analysis based on these routing criteria as well as other factors determined from site visits and discussions with property owners and other key stakeholders.

The company relies on input from the community to determine an appropriate solution that will meet the need, while reasonably minimizing impacts to the community being served.
Prior to building transmission lines requiring new right of way, Dominion Energy acquires perpetual rights from the owners of properties along the approved route to construct, operate and maintain electric lines across private land. An easement is obtained by Dominion Energy from the property owner in the form of Dominion Energy’s standard right of way agreement and the document is recorded in the land records of the County or City where the property is located.
This project supports Prince William County’s economic development commitments and successes in reaching its economic development goals. New energy infrastructure will help support long-term economic growth in this area. For area residents and businesses, this also means improved reliability which should result in fewer outages and shorter durations if outages do occur. Constructing a new substation in our proposed location will provide redundancy in the network therefore reducing risk and improving reliability for the future.
Due to the interconnected nature of the electric transmission grid, all NOVEC customers rely on Dominion Energy's transmission infrastructure to deliver reliable power.
The Virginia State Corporation Commission may issue dates for a public hearing in the local area, with an evidentiary hearing in Richmond thereafter. Citizens are encouraged to participate in the process and provide input. The SCC maintains copies of all documents related to the case. Updates about the status of the application can be found on the SCC website.
Yes. The company, at its expense, will repair any private roads damaged by Dominion Energy or its contractors during construction of the line or during future maintenance. In addition, we will reimburse property owners for crop damage and repair or replace fences or gates if they are damaged.
As part of the SCC application, Dominion Energy will complete an evaluation of potential environmental, cultural, and historical impacts of the Haymarket 230kV Line and Substation Project. Dominion Energy works with many local and state agencies to complete these evaluations and mitigate any impacts. The company also submits annual Erosion and Sedimentation (E&S) Control Specifications and an anticipated list of transmission line projects for the construction and maintenance of transmission lines to the Virginia Department of Environmental Quality for review and approval. For program year 2015, this project will be included in the annual submittal for approval prior to construction. Our contractors receive copies of the E&S specifications and any additional permit conditions prior to construction and are directed to meet all requirements. The right of way will be rehabilitated when construction is complete.

Property owners will be notified before construction clearing begins.

Prior to building a new power line, the right of way must be cleared to allow construction activities and eventual transmission line operation that is safe and reliable. Existing low-growing vegetation may be left in place if it does not interfere with construction activities. Additionally, trees located outside of the right of way which are tall enough to potentially impact the transmission line may also be removed. These trees are commonly referred as danger trees: view a diagram of typical danger tree clearances.

Trees are cut to be no more than 3 inches above ground level. In the right of way, debris that is adjacent to homes will be disposed of by chipping or removal. In other more rural areas, debris may be mulched or chipped as practicable. Clearing will be accomplished by hand in wetland areas and within 100 feet of streams. Care will be taken not to leave debris in streams or wetland areas. Matting will be used for heavy equipment in these areas. Erosion control devices will be used on an ongoing basis during all clearing activities.
