AES Ohio is proposing the construction of the new electric transmission, Madison 345 kilovolt (kV) substation project, located south of South Charleston, in Madison Township, within Clark County, Ohio.
The proposed project involves the construction of the new 345/69k V substation of approximately seven acres, located on South Charleston Pike (SR-41). The project will tap into the existing Greene-Beatty 345 kV transmission line and will install eight 345 kV breakers arranged in a breaker-and-one-half configuration, three 69 kV breakers also arranged in a ring bus, a 345/69kV transformer and associated equipment. The proposed project is located entirely on AES Ohio-owned property.
This project is needed to provide reliability in the southeastern portion of the AES Ohio service territory through a new source to radial substations.
The Madison 345 kV substation is located on SR-41 (South Charleston Pike), south of South Charleston, in Madison Township, within Clark County, Ohio.
