As we remain focused on reliability and resiliency, we have identified a transmission corridor in Colleton and Hampton counties near U.S. Highway 17-A (Hendersonville Highway) that will be enhanced to meet the growing energy needs of our customers. 
 
Dominion Energy contractors will add new self-supporting steel poles to support two new 230 kilovolt (kV) lines. These new poles will run parallel with the existing wooden h-frame line along established rights of way.  Dominion Energy will then convert the existing wooden structures to a 115kV line to efficiently carry more load on the system.
