The Harrison Power 138-kV Transmission Line Project involves a new approximately 4.5-mile, 138-kV transmission line that would deliver energy from the Harrison Power Plant switchyard to the bulk power system. The proposed 138-kV transmission line point of interconnection would be American Electric Power’s existing Nottingham substation. The project’s estimated cost is $20m, with a proposed construction period of six months to be commenced in late 2018. Public Utilities Commission of Ohio staff on Aug. 28 recommended that the Ohio Power Siting Board (OPSB) recommended that the OPSB find that the basis of need for the project has been demonstrated and therefore complies with certain requirements, provided that any certificate issued by the OPSB for the proposed facility include certain conditions.
