AES Ohio is proposing the construction of the Franklin substation and 138 kilovolt (“kV”) expansion project, located in Franklin Townships, in Shelby County, Ohio.

The proposed project involves the construction of the new 138kV Franklin substation of approximately two acres, located on a private access road east of Wenger Road (SR-50), and associated transmission line work. The proposed project is nearly entirely located on properties currently owned by both AES Ohio and Honda Development and Manufacturing of America (“HDMA”). Transmission work includes dividing the existing 138kV transmission line, 13827 Amsterdam-Shelby into two segments: 13827 Shelby-Franklin and 13853 Franklin-Amsterdam. Both segments will connect to the new Franklin substation as well as the new 138kV circuits intended as part of this project. The new transmission lines are 13860 Franklin-Honda I, 13861 Franklin-Honda II, and 13854 Sidney-Franklin. Also, in order to extend the 13827 Shelby-Franklin circuit to the Franklin substation, a single structure located in an existing right of way (“ROW”) on the east side of the new substation will be replaced. Transmission lines 13860 and 13861 will connect the Franklin substation to the existing Honda substation, 0.6 miles to the east.

The proposed project is needed to improve the resilience and reliability of the area power system, increase operational flexibility, and to meet the requirements of HDMA and the surrounding transmission network.
