The Liberty-Cannon Branch 230 kV Upgrade Project is necessary to maintain safe and reliable electric service for our customers and comply with mandatory standards for the electric transmission system. This project involves uprating existing 115 kilovolt (kV) lines between Liberty and Cannon Branch substations to 230 kV and removing existing 115 kV lines between the City of Manassas’ Dominion and Lomar Delivery Point substations.
For the line upgrades, most of the existing transmission structures and wires, or conductor, can accommodate the voltage increase and will not be changed or replaced. Construction needs for this portion of the project are limited to upgrading and reconfiguring equipment in and around the substations along the project route. For the line removals, we will remove the conductors and 14 structures within approximately 1,800 feet of right of way and restore the impacted areas to their preexisting conditions.
