Southern FostoriaTransmission Improvements

AEP Ohio representatives identified a need to upgrade the power grid in Seneca and Hancock counties to support increasing electricity demand.

Southern Fostoria Transmission Improvements involves:

  • Building Iron Triangle Switch along the Howard Fostoria 138-kilovolt (kV) transmission line
  • Building approximately 3 miles of 138-kilovolt (kV) transmission line
  • Adjusting .2 miles of power line to accommodate the new swith pole

The project provides power to North Central Electric Cooperative’s (NCE) Loudon Substation on Township Road 217 in Fostoria. The proposed switch pole and power line connects the new substation to the existing power grid. Creating a stronger transmission grid benefits the local distribution companies and electric cooperatives who receive power from the transmission lines.


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