Transmission lines are a system of electrical wires that carry large amounts of energy over long distances. These wires can run from generation stations to substations where energy is converted to lower distribution levels to serve homes, schools, hospitals and businesses in the community. If you’ve ever heard a reference to the energy grid, that’s the network of the transmission and distribution systems. View a short video to learn more about the importance of the electric transmission system.

The company first identifies potential corridors and seeks feedback from the community. A corridor is a study area that represents the potential path of a transmission line. The specific transmission routes will be much narrower and located in easement areas negotiated with property owners. These specific locations will later be determined following public input and further study. This additional study examines land use, connectivity to other power lines, engineering construction and complexity, and ecological and cultural resources, such as wetlands and historic sites.

We are in the preliminary stages of selecting the preferred route for the transmission line, where we’re seeking public input. We hope to finish construction by July 2025.

This project will involve the relocation of steel tower structures and double-circuit 345-kilovolt (kV)/138-kV transmission lines. Some tower structures may be replaced with steel pole designs.

Once we select the preferred route for the new transmission lines, we will negotiate with landowners to obtain the required easements – or land rights – for the new transmission lines.

An easement is a legal agreement that gives Duke Energy the right to use, not own, specific portions of land for certain purposes. Easements get recorded on the property deed and remain in effect after properties are sold to a new owner.

Easement area widths are expected to be 150 feet. We will work directly with property owners who are affected by easement acquisition.

Trees and other woody vegetation growing near overhead electric lines create safety hazards for workers as well as the public when they are at risk of causing an electrical outage. Duke Energy will work directly with property owners if tree removal is needed on their property to safely relocate the transmission line.

Many factors are considered when building a new transmission line. Part of this phase involves gathering information about the project area to properly design the project. Get a look at some of these activities in this short video.

Many studies have examined EMF from power lines, household appliances and other devices with an electric current. After decades of research, scientists have not established a conclusive link between EMF exposure and its effects on human health. Learn more about electric and magnetic fields.
