Possum Point – Smoketown Electric Transmission Improvement Project

We are committed to continually reviewing and analyzing our energy infrastructure to provide the most safe and reliable electric service to our neighbors. It has become necessary for us to address two existing transmission lines that have been in operation for nearly 70 years.

Project Update

On February 5, 2018, the Virginia State Corporation Commission (SCC) issued it final order approving this project. In its final order, the SCC found, among other things, that there is a need for the rebuild and that using the company’s proposed solution using a 230 kV designed transmission line (operating at 115 kV) using galvanized monopoles (please see renderings below) and existing rights of way reasonably minimizes adverse effects.

Benefits

  • Requires no new right of way
  • Replaces the lines consistent with current electrical and safety standards
  • Creates flexibility in the network to address potential future needs
  • New structures are generally comparable in height and location to the existing 230kV lattice structures

Overview

Dominion Energy has an existing electric transmission corridor that runs from its Possum Point facility in Prince William County up through Dumfries and north into the Dale City area west of I-95. In this corridor, there are two 115 kilovolt (kV) electric transmission lines that exclusively serve three NOVEC substations which provide power to more than 11,000 NOVEC customers.

Purpose

The key purpose of this project is to replace old infrastructure. The 115kV lines were originally built in 1948 and 1954 on wooden poles. Although well maintained, it has come time to completely replace these old transmission lines before they become a reliability concern.


SCC Approval Process

The State Corporation Commission (SCC) is responsible for verifying the need, determining the route and reviewing the environmental impact of certain transmission lines in Virginia.

On June 5, 2017, Dominion Energy submitted its application regarding the Possum Point-Smoketown Project and on February 5, 2018, the SCC approved the project. Documents related to the case are available to the public on the SCC Docket Search section of the SCC website, in the "Search Cases" section – Case No. PUR-2017-00078. In addition, interested parties may comment directly to the SCC by sending an email to sccinfo@scc.virginia.gov.
