Spring Hill to Tysons 230 kV Underground Transmission Line Project

At Dominion Energy, we are committed to continually reviewing and maintaining our energy infrastructure to provide safe and reliable electric service. We believe solutions should always account for future energy needs while continuing to balance cost and impacts.

Project Overview

This project will replace a portion of an existing 230-kilovolt (kV) above-ground line in Tysons with a new 230kV underground line running from the existing Tysons substation on Tyco Road and terminating at a structure near the Future Spring Hill Substation southwest of Leesburg Pike and Spring Hill Road.
