Clendenin – Walton Area Improvements

Transource Energy plans to shore up the electric transmission grid in parts of West Virginia with a $75 million electric grid expansion. The anchor of the project is a new transmission line and key substations that will be constructed and owned by Transource, an affiliate of American Electric Power.

The Clendenin – Walton Area Improvements Project includes construction of approximately 25 miles of new 138-kilovolt (kV) transmission line, three new substations and making additional upgrades to other transmission facilities in the area. The proposed work will provide this region of West Virginia with a robust transmission grid capable of handling the area’s increase in demand while ensuring continued reliable service to local customers in Kanawha and Roane counties.

PJM Interconnection, the regional transmission organization responsible for monitoring the electric grid in 13 states including West Virginia, identified the need for the project in its 2014 Regional Transmission Expansion Plan. In 2015, PJM awarded the project to Transource, a partnership between AEP and Great Plains Energy. In June 2016, the Public Service Commission of West Virginia granted Transource approval to construct the project. Appalachian Power and First Energy will construct additional facilities to incorporate with the grid upgrades. Construction is expected to start in 2017 and be completed in 2019.

Project Updates

Transource has finalized the routing process of the transmission line. Emerald Energy, the company’s right-of-way representative, will now start contacting landowners.
