Mount VernonTransmission Line Rebuild Project

AEP Ohio representatives plan power grid upgrades in Knox County.

The Mount Vernon Transmission Line Rebuild Project involves:

  • Rebuilding about 4 miles of 69-kilovolt (kV) transmission line between West Mount Vernon Substation off Pleasant Valley Road, Pittsburgh Avenue Substation off Pittsburgh Avenue and Mount Vernon Substation off Roundhouse Lane.
  • Removing a half-mile of 69-kV transmission line between Arch Avenue and North Mount Vernon Substation off Garden Aly.
  • Upgrading West Mount Vernon, Pittsburgh Avenue and Mount Vernon substations.
  • Upgrading South Mount Vernon Switch, located off Terrace Avenue.

Company representatives plan to rebuild the power line in the existing right-of-way, which may require acquiring new or updating existing property easements. Easements are defined land rights that property owners grant the utility to allow for the safe construction, operation, and maintenance of the power line.

This project upgrades local transmission lines and vintage 1950s equipment that needs to be replaced. Upgrading the infrastructure to modern standards reduces the need for frequent maintenance and speeds recovery of service when outages occur.

Crews expect construction to begin spring 2023 and conclude summer 2025.
