WheelersburgArea Improvements Project

AEP Ohio representatives plan to upgrade the electric transmission network serving customers in Scioto County.

The Wheelersburg Area Improvements project involves:

  • Building about 5 miles of 138-kilovolt (kV) power line
  • Rebuilding about 2 miles of 138-kV power line
  • Removing about 10 miles of transmission facilities
  • Installing two switch poles to control the direction of electricity flow throughout the lines
  • Replacing Wheelersburg Substation located on Earwood Lane with Sweetgum Substation located near OH-522 and Mill Road
  • Building Althea Substation located off Gallia Pike in Franklin Furnace

The project provides an additional power source to the area and enhances electric service reliability to customers. The additional power source allows crews to retire about 10 miles of deteriorating power line that dates back to 116. Company representatives plan to build Sweetgum Substation to replace the aging Wheelersburg Substation to allow for adequate space for the modern equipment needed to continue serving area customers. Adding switch poles to the area provides the ability to isolate equipment from the power grid, speeding recovery of service when an outage occurs.

Company representatives plan to evaluate study segments in the area. Study segments are multiple alternatives presented to determine a line route. Company representatives do not build all study segments, rather, they select one route to build based on public feedback and feasibility.

This project requires Ohio Power Siting Board (OPSB) approval.
