Marysville-Hyatt 345 kVTransmission line Rebuild Project

AEP Ohio representatives plan power grid upgrades to improve electric reliability for customers in Delaware and Union counties.

The Marysville-Hyatt 345 kV Transmission Line Rebuild Project involves:

• Rebuilding approximately 19 miles of power line between Hyatt Substation in Powell off Sawmill Parkway to an existing transmission structure located off Harmon Patrick Road in Richmond.
• Rebuilding nearly 4.5 miles of power line from Marysville Substation off Reed Road in Marysville to an existing transmission structure located off Harmon Patrick Road in Richmond.

Company representatives plan to rebuild the power line in the existing 150-foot-wide right-of-way corridor. Existing easements may need to be updated to ensure the safe construction, operation and maintenance of the line.

* This project requires regulatory approval from the Ohio Power Siting Board (OPSB)
