Wilmington Northeast Reliability Project

Fostered by the expansion of Highway 17 and the future expansion of Military Cutoff Road, electric demand is growing northeast of Wilmington. Additional capacity on the electric distribution lines that serve area homes and businesses is needed. To meet this anticipated demand, a new substation and transmission line are planned.

The new substation will be built on Duke Energy-owned property located off Porters Neck Road. This station will house new technologies designed to enhance electric power reliability, increase available electricity and increase resiliency during severe weather events.

To power the substation, a new 4.6 mile, 230-kilovolt (kV) transmission line will be constructed. The new transmission line will tie to the Castle Hayne-Folkstone 230-kV line.
