Meeting the growing energy needs of Anderson County

Project Overview

Residential, commercial and industrial development in northeastern Anderson County has increased energy demands in the area. To keep pace with the growing needs, Duke Energy plans to upgrade the transmission system in Anderson County by constructing a new 100k/12.5-kV substation along with a 100-kilovolt (kV) transmission line.

The site for the new substation is on an undeveloped parcel on Highway 81 North.  The facility is one of several projects in the region designed to strengthen the grid, improve reliability and enhance service to Duke Energy customers. These improvements will help support economic and community growth, make the grid more resilient to power outages and prepare the system for future energy opportunities.

Project Timeline

  • Transmission Line Study

    We will conduct a transmission line siting study, gathering 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.

  • Substation Site Development Construction Activities (2024)

    • Construction entrance established
    • Vegetation and tree removal for substation pad, transmission, and distribution corridors on-site
    • Grading site in preparation for substation construction
    • Contractors mobilizing heavy equipment and materials to the site

    Substation Construction Activities (2026)

    • Continue receiving delivery of materials
    • Coordinate traffic management measures
    • Install substation security fence on the site
    • Erect steel for substation equipment
    • Install substation equipment within a fence

Frequently Asked Questions

  • Currently, vegetation removal is expected to begin in 2023. Site grading and civil construction are expected to begin in 2025. Construction is expected to be complete by 2026. (The project timeline should be applicable to both the entire project and the transmission line.)

  • Safety risks to the community will be negligible, and similar to any other small-scale land development project during construction.  The only measurable safety risks will be associated with temporary construction traffic.  After construction the substation will be virtually dormant within the community.  Traffic in and out of the site will be minimal, and it will likely only include one or two visits a month by Duke Energy personnel.

  • A normal increase in construction-related traffic is expected. Typical construction work hours are 7 a.m.—7 p.m. Monday through Friday. Following construction, the substation will be an unmanned facility, with maintenance activities resulting in 1 - 2 trips a month to the substation.

  • The site will be secured by a 7-foot chain-link fence. During construction, the contractor will take appropriate steps to secure the site.

  • Duke Energy will take all reasonable measures to avoid impacts and/or intermittent disruptions of power during construction of this project. Minimal potential impacts could be related to outage requirements on the existing transmission line that could affect larger businesses. However, if outages are anticipated we would work them to mitigate any impacts. However, there should be no impact to distribution customers.
