Guernsey-Harrison Power 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 Updates

AEP Ohio and its affiliate, AEP Ohio Transmission Company, hosted a public informational open house on September 26. Visitors offered input, asked questions of project team members and learned more about the new transmission line. The project team will work on selecting a line route for the new 5-mile section. Field work will begin this fall on the rebuild portion of this project.
