Southeast ColumbusArea Improvements Project

AEP Ohio representatives plan to upgrade the electric transmission network serving customers in southeast Columbus and Groveport.

The project involves:

  • Building approximately 5 miles of 138-kilovolt (kV) transmission line between Groves and Shannon substations
  • Rebuilding approximately 4.5 miles of 138-kV transmission line between Astor and Shannon substations
  • Rebuilding approximately 4.5 miles of 138-kV transmission line between Bixby and Shannon substations
  • Expanding Shannon Substation near the intersection of Shannon Road and Brice Road

We are requesting feedback on possible route options. Your feedback is important to us and helps our team determine a power line route that minimizes impact to the community and environment.
