Dominion Power will be formally filing their application to the Virginia State Corporation Commission (SCC) for approval of their Haymarket Transmission and Substation Project, Friday, naming the I-66 overhead route as their “Preferred Route.”

The preferred route is shown in dark blue on the map.

Chuck Penn, a spokesperson for Dominion Power, explained their choice of the I-66 overhead route.

“The Company chose the I-66 overhead route that runs parallel to Interstate 66 as its Preferred Route because it provides an opportunity to maximize co-location with existing infrastructure (primarily I-66), and presents a reasonable cost compared to the other Alternative Routes, and it provides the shortest and most direct route to the proposed Haymarket Substation.”

Penn said that after receiving “extensive feedback from the community, VDOT and VRE,” Dominion has made some slight tweaks to the I-66 overhead route from what was shown at the July Open House.

The most significant change is that “the route now parallels the north side of I-66 for the first three miles instead of running along the south side where the alignment was previously.”

Tweaks were made “to address potential pinch points between Dominion, VDOT and VRE,” Penn said.

Penn provided the additional details below.

Regarding Alternatives in our SCC application:

As previously presented in our July Open House, the I-66 Overhead/Underground “Hybrid” Route, Railroad Route, Carver Route and Madison Route are presented in the application as alternatives.
We clearly note that the New Road Route, Northern Alternative and Wheeler Route are rejected options.
Further details can be found in the application and the routing study once the application is filed and made public.
We will post the filing to the project page on
Regarding SCC process:

Once we file, the next steps are:
1. SCC creates a public electronic docket on the case that will be available on its website for Case No. PUE-2015-00107 (we will link to the docket as well from

2. SCC will assign a Hearing Examiner to precede over the case.

3. It typically takes about three weeks or so from the time of filing for the Commission to issue an order setting out the procedural schedule, which includes when the public comment period opens and closes, any public hearing dates and locations, when interested parties can formally join the case, when SCC Staff and Dominion testimony is due, and when the Evidentiary Hearing will be held.

4. The entire process could take up to, on average, 18 months for a decision to be rendered by the Commission.

“We cannot thank the many people – residents, public officials, community leaders – enough for their valued input,” Penn said.
