AEP Ohio Transco: Construction of 138-kV project to begin March 6

Construction of the Barnesville-Summerfield 138-kV Transmission Line Project will begin on March 6, American Electric Power’s (NYSE:AEP) AEP Ohio Transmission Company (AEP Ohio Transco) told the Ohio Power Siting Board (OPSB) on Feb. 21.

As TransmissionHub reported, the OPSB, in a Feb. 2 order, approved and adopted stipulations related to two rebuild projects that were filed by regulatory staff and AEP Ohio Transco, including the Barnesville-Summerfield project, which involves building the Barnesville-Summerfield transmission line in Belmont, Guernsey, and Noble counties.

The line will run from the existing Summerfield distribution substation and a planned Barnesville substation, which would replace the existing Barnesville substation. The OPSB also said in its order that the project will rebuild the existing Barnesville-Summerfield 69-kV Transmission Line that services the village of Barnesville and was built in 1943.

The preferred route for that project is about 15.8 miles long and predominantly parallels the existing Barnesville-Summerfield 69-kV Transmission Line. The route, the OPSB added, would be offset by about 25 feet from the centerline of the existing 69-kV line in order to ensure safer construction and reliability, as well as to allow the existing line to remain in service during construction.

The preferred route exits the existing Summerfield substation and follows the existing 69-kV line to the northwest for about 1,200 feet, then turns to the northeast along State Route 513 for about nine miles, the OPSB said. The route continues along State Route 147, State Route 513, and then cross-country, for an additional six miles before running south of Sycamore Street in southern Barnesville, to the planned Barnesville substation. The OPSB also said that the preferred route deviates from the existing 25-foot offset of the existing Barnesville-Summerfield Transmission Line at certain locations in order to avoid residential structures and other sensitive land use features.

AEP Ohio Transco estimates that the total applicable intangible and capital costs for the Barnesville-Summerfield project is about $32.6m.

As noted in the Feb. 2 order, the other project involves installing in Belmont County a new 138-kV overhead electric transmission line between the existing Speidel substation and a planned Barnesville distribution substation. The project would rebuild the existing Speidel-Barnesville 69-kV Transmission Line, which services the village of Barnesville and was built in 1914, the OPSB said.

The preferred route is about 3.7 miles long and predominantly parallels the existing Speidel-Barnesville 69-kV transmission line, the OPSB said, adding that the route would be offset by about 25 feet from the centerline of the existing 69-kV line in order to ensure safer construction and reliability, as well as to allow the existing line to remain in service during construction.

The preferred route exits the existing Speidel substation and follows the existing 69-kV line to the south and southwest for about 2.8 miles, the OPSB said. The preferred route splits off the existing 69-kV route just south of Grace Avenue, the OPSB said, noting that for 0.9 miles, the preferred route traverses open pasture and wooded land to the south and southwest, until it reaches the planned Barnesville substation, south of the village of Barnesville.

AEP Ohio Transco estimates that the total applicable intangible and capital costs for the Speidel-Barnesville project is about $16.6m for the preferred route.
