Reliability is a responsibility that Duke Energy takes very seriously. We are working on building a smarter energy grid, which includes upgrading the electric transmission system in southwest Ohio.
The Duke Energy transmission project at the City of Hamilton Substation, located on North Gilmore Road, will improve the reliability of electric service for customers in Butler County.
The project will enable Duke Energy to perform any future repairs inside the substation without service disruption to customers in the city of Hamilton. The present setup inside the substation demands a great deal of coordination between Duke Energy and the city when repairs become necessary. The upcoming restructuring of the City of Hamilton Substation will provide service reliability and flexibility of operations.
The proposed project involves modernizing and restructuring equipment inside the substation and relocating a 138-kilovolt (kV) transmission line to divide energy into multiple sources, rather than the present single-source system inside the substation. This will allow flexibility for repairs without advanced scheduling and planning. Two steel 138-kV transmission poles will be relocated on the city-owned property outside the substation, along with approximately 200 feet of 138-kV transmission line. The steel monopoles are approximately 180 feet tall.
Construction is scheduled to begin in mid-February 2020, with completion in June 2020.
In relation to this project, a notice to construct, operate and maintain this project is now pending before the Ohio Power Siting Board (OPSB) in Columbus, Ohio.
