Updates

• Overhead
  • November 2020 – Crews have completed installing the new structures and pulling in conductor wire. Temporary access roads and construction equipment will be removed and the right of way will be replanted.
• Underground
  • January 2021 – Crews have completed 3 of 4 HDD drill paths at the I-66 crossings. The final bore is nearly complete. Crews have installed approximately 2/3 of the duct bank in open-trenching sections.
• Substation
  • January 2021 – Construction at Haymarket Substation is ongoing.

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.
