Conesville-West Millersport 765kV Transmission Line Project

AEP Transmission representatives plan to upgrade the transmission grid in Coshocton, Muskingum, Licking, and Fairfield counties to help keep electricity flowing safely and reliably now and into the future.

This project involves upgrading approximately 50 miles of existing 345-kilovolt (kV) transmission line within existing right-of-way to 765-kV capacity, and constructing up to 14 miles of new 765-kV transmission line to connect the line to the proposed West Millersport Substation.

Some property owners may have received communications from Grid Growth Ventures about a separate transmission project in the area. Both projects help address regional transmission needs identified through PJM's planning process, which oversees the transmission grid in Ohio. While the projects are being developed by different companies, both are designed to support future electric reliability. If you have questions regarding potential property impacts associated with a Grid Growth project, please visit GridGrowthVentures.com for more information.

Project Updates

Fall 2026: AEP Transmission hosted two in-person open houses on October 13 and October 14 discuss the project and obtain feedback from the community. A virtual open house is available on the right side of the page. Company representatives are accepting feedback through Wednesday, October 28.

As the project continues to develop, field studies are needed to help the project team decide on the final line route, as well as support engineering and environmental efforts. As part of this work, landowners may be contacted by Contract Land Staff (CLS), the right-of-way company working on behalf of AEP Transmission. Field studies do not confirm a line route but are a tool used to help the team during the evaluation process.
