Patina - MirkwoodTransmission Project

AEP Ohio representatives plan power grid upgrades in Madison County. The project involves building Patina Station, Mirkwood Station, and about 11 miles of transmission line to provide power to a customer facility and help meet the area’s growing electrical load demand.

The project involves:

Building Patina Station near the intersection of Rosedale-Plain City Road and State Route 38 and Mirkwood Station near the intersection of State Route 161 and Cemetery Pike.
Building two 11 mile 345-kilovolt (kV) double circuit transmission lines connecting Patina and Mirkwood stations.
Transmission improvements connecting AEP Ohio and customer facilities to the power grid.

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

Company representatives plan to evaluate study segments in the area for the proposed power line corridors. Study segments are multiple alternatives presented to determine line routes. Company representatives do not build all study segments, but rather they select two transmission line routes based on public feedback and feasibility.
