Monroe Transmission Line Extension Siting Study

Transmission Investments

Duke Energy’s electric system is essential to meeting our customers’ needs. We’re also committed to the development, stability and economic growth of the communities we serve. With that in mind, Duke Energy Ohio is planning to extend an existing 69-kilovolt (kV) transmission line to the Duke Energy-owned Dayton Tech Substation – located at Deneen Avenue in Monroe – and the Worthington Steel company-owned substation on North Garver Road in Monroe.

Project Need

Both substations presently are served by only one Duke Energy-owned transmission line. By adding this separate transmission line loop into the substations, this project will add capacity for future growth in the region, as well as increase reliability by providing alternatives for routing power during severe weather events. These alternatives help reduce outage and restoration durations.

Project Description

The extension of the transmission line is approximately 1 mile. Public input is invited as part of this project as the study factors land use, ecological and cultural resources and complexity of engineering and construction. This three-phase process is considered a comprehensive, fair and balanced approach toward selecting potential routes for transmission lines.


Community engagement is a vital part of our siting process. It allows us to receive and consider public input and to share information with the community about this project.We invited landowners within 500 feet of the study area to send us their feedback.

The public comment period was held from Aug. 24 to Sept. 22, 2021.

After examining public comment and additional study on how to best approach the project with the least impact to property owners, the community and the environment, Segments 7, 6. 5 and 3 were identified as the preferred route.

We believe this option will have the least overall impact on property owners, businesses, historic areas and the environment. The precise location of the transmission line and pole structures within the easement will be determined following easement negotiations with affected landowners, a detailed route survey, additional field study and completion of the engineering design of the route.
