OPSB approves new electric transmission lines in Miami, Wood counties

COLUMBUS, OHIO (Jan. 16, 2020) – The Ohio Power Siting Board (OPSB) today authorized Dayton Power and Light (DP&L) and American Transmission Systems, Inc. (ATSI) to construct 138 kilovolt electric transmission lines in Miami and Wood counties, respectively.

In Miami County, DP&L will construct the West Milton-Eldean Transmission Line. The transmission line route, spanning 16.7 miles between the existing West Milton and Eldean substations, will be located in parts of the village of West Milton, the city of Troy, and unincorporated Union and Concord townships. The transmission line is needed to mitigate a potential violation of mandatory electric reliability standards and to meet electric safety code requirements. The $16 million project will improve electric service reliability in the northwest portion of DP&L’s transmission system.

ATSI will construct the Wood County Reinforcement Project, a 6-mile transmission line connecting the Lemoyne-Midway Transmission Line to the Brim Substation. The transmission line route spans parts of Middleton and Plain townships. The $8.4 million project will improve the quality and reliability of electric service and expand the transmission system to meet anticipated growth in Wood County.

Additional information about today’s OPSB decisions, including maps of the approved transmission line routes in case numbers 18-1259-EL-BTX and 18-1335-EL-BTX, is available at www.OPSB.ohio.gov.


The Ohio Power Siting Board reviews applications for the construction of major utility facilities in Ohio. Together with Ohio’s elected officials, citizen stakeholders, and the energy industry, the Board strives to build a strong and competitive foundation for Ohio’s future.
