Woodmont Transmission Line Routing Study

Formerly Canterburry Transmission Line Routing Study
Duke Energy is committed to providing safe, reliable and affordable energy to customers. Maintaining a robust system for supplying and delivering electricity is critical to ensuring the continued reliability and economic prosperity of the region.

About the Woodmont Substation and Transmission Line Routing Study

Duke Energy has identified a need to upgrade the transmission system in Greenville County. 

To meet our customers' increasing demand for energy, the company plans to construct an estimated 1-mile, single-circuit, 100-kilovolt (kV) transmission line to connect a new substation to our existing bulk transmission infrastructure.

We are conducting a transmission line routing study to gather data to determine the least impactful route. This three-phase transmission line routing study is widely utilized within the electric utility industry as the most comprehensive method to identify a future transmission line corridor.

Duke Energy this month was planning to host an open house notifying residents of the upcoming Woodmont project. Due to the Hurricane Michael and impending inclement weather, the open house was postponed until October 30th.

Project Description

  • Perform a transmission line routing study to include an open house to gather public input for consideration.
  • Determine a preferred route based on the routing study analysis and announce the preferred route to the community in the first quarter of 2019.
  • Construct a new 100-kV transmission line from a tap point along existing transmission infrastructure to the proposed substation. 
  • The proposed new 100-kV transmission line is estimated to be 1 mile in length. Conclusion of the routing study analysis will determine the length.
  • The line will be built using concrete and/or steel monopoles approximately 80 to 110 feet tall. 

Benefits to the Community

New transmission infrastructure in the area:

  • Enhances the ability for Duke Energy and neighboring utilities to provide safe and reliable energy to homes, community facilities and businesses in the area.
  • Enhances capacity to meet the demands of growing energy needs in Greenville County.
  • Ensures more flexibility for providing critical energy needs to communities in the region and maintains a robust system for supplying and delivering energy, which is integral to ensuring continued economic prosperity in the region.

Public Informational Meeting

Duke Energy appreciates feedback from the community and remains committed to conducting an open route-selection process. The company will ensure the route selected has the least overall impact on property owners, the environment, and the community. The public informational meeting was held in Greenville County in 2018. Duke Energy is also collecting comments by phone, email and an electronic comment form on the Duke Energy website.
