At Dominion Energy, we are dedicated to maintaining reliable and secure electric service in the communities we serve. The Carson-Locks 230 kilovolt (kV) Electric Transmission Rebuild Project proposes to rebuild and reconductor 10.34 miles of existing 230 kV transmission lines that run from the Carson Substation on Ellington Road in Dinwiddie County to the Locks Substation on Rawlings Lane in the City of Petersburg.
To maintain reliable service for our customers, we need to rebuild the existing transmission line from the Carson Substation to the Locks Substation. In addition to replacing the current 230 kV wires, a process known as reconductoring, we will also need to replace the transmission structures. Reconductoring will increase the ampacity, or maximum current carried, on the line. The line will be rebuilt within the existing right of way; therefore, no new permanent right of way is required. The lines were built primarily with wooden H-frame structures. We are proposing to rebuild these with mostly weathering steel (brown) H-frame structures, which require less maintenance and have a longer service life. The new structures will be, on average, approximately five feet taller than the existing structures. This project will ensure the continued safety and reliability of the electric grid.
