Oakley Underground Line Relocation

Restoration Schedule (Schedule may fluctuate depending on circumstances such as weather conditions)

• Additional work at the sites of the manholes is planned for early 2025. We’ll provide an update when the 2025 schedule is finalized. This work will not have significant traffic restrictions.

Reliability is a responsibility Duke Energy takes very seriously. As part of our commitment, we are repairing an existing 138,000-volt (138-kV) transmission line buried under Madison Road in Oakley (Hamilton County).

The trench or tunnel that houses the underground transmission line was installed in the 1940s. Previous efforts were unsuccessful for repairing the transmission line in place. As a result, we will relocate a 0.3-mile (~1,700 feet) section of the new transmission line in another area under Madison Road to make the repairs. The transmission line is a vital component of our electric system in Greater Cincinnati.

Project Description

This work will involve excavation under Madison Road to install the new section of transmission line. The repaired transmission line will be installed in protective plastic sleeves, which are then fully encased in steel-reinforced concrete.

An application to construct, operate and maintain this project has been approved by the Ohio Power Siting Board (OPSB). Letters also were sent to neighboring property owners and tenants, explaining how they could participate in the process. View the copy of the application filing.
