Guernsey-HarrisonPower Improvements

The Guernsey-Harrison Power Improvements upgrades about 24 miles of 69-kilovolt transmission line in Cambridge, Center, Wills, Madison and Londonderry townships in Guernsey County and Freeport Township in Harrison County. The project is needed to update the transmission line to improve electric reliability for area customers by decreasing outages. The project includes rebuilding about 19 miles of the existing line in the current right-of-way. The remaining 5 miles will require construction in new areas to accommodate a line reroute and require acquiring new easements. We are asking for input on the proposed study segments so we can determine a route for the new section of line.

The line will use primarily steel single pole structures that will be about 80-feet tall. AEP Ohio anticipates completion of this project in late 2020. Early estimates show this is an approximate $25 million investment.

Project Timeline



Proposed structures will vary depending on location. The project will use several structure types, including steel H-frame and single poles that will be between 70-85 feet tall. The structures will be placed in the center of an approximate 100-foot wide right-of-way corridor.
