American Electric Power’s (NYSE:AEP) AEP Ohio Transmission Company (AEP Ohio Transco) on Jan. 4 filed with the Ohio Power Siting Board (OPSB) a pre-application notification letter for the Vigo-Pine Ridge Switch 138-kV Transmission Line Project, which is part of the overall Jackson-Ross Area Improvements Project.
A portion of the existing Berlin-Ross 69-kV line would be rebuilt to a 138-kV transmission line that connects the Vigo substation in Ross County to the Pine Ridge switch in Jackson County, the company said.
The Vigo-Pine Ridge project would be about 10.5 miles long, the company said, noting that the line would run through Jefferson Township in Ross County and Liberty Township in Jackson County.
AEP Ohio Transco said that it estimates that the project would cost about $21m.
The new line would have steel monopoles or H-frame structures; conductor; shield wire; and associated hardware.
Separately on Jan. 4, the company filed a pre-application notification letter with the OPSB for the Pine Ridge Switch-Heppner 138-kV Transmission Line Project, which is also part of the overall Jackson-Ross Area Improvements Project.
The company noted that a portion of the existing Berlin-Ross 69-kV line would be rebuilt to a 138-kV transmission line that connects the Pine Ridge switch to the proposed Heppner station in Jackson County.
The Pine Ridge Switch-Heppner project would be about four miles long, the company said, adding that the line would run through Liberty and Coal townships in Jackson County.
AEP Ohio Transco said that it anticipates building the new line using several structure types, including steel H-frame and monopoles. The line would also have conductor, shield wire, and associated hardware, the company said.
The company noted that it estimates that the project would cost about $9m.
In both filings, the company said that it plans to hold a public information meeting about the projects on Jan. 25 in Jackson, and that it expects to file – for each project – the application for a certificate of environmental compatibility and public need with the OPSB in the spring.
