Working to improve the reliability of your electric service in Butler County.

Visit our virtual open house.

Project overview

The Ross Transmission Line Extensions Project will help improve the reliability of the electric transmission system by building four 69-kilovolt (kV) transmission lines in and out of a new electric switching substation. The Ross Substation is under development on Duke Energy property along Ross Millville Road (U.S. 27). Four transmission lines will run in and out of the substation. Two new 69-kilovolt (kV) transmission lines will exit directly to U.S. 27 on Duke Energy-owned property. Two of the new transmission line extensions will involve easement acquisition.
