    Amsterdam-West Moulton 138kV improvements

    AES Ohio is proposing the construction of a new 138kV line extension that will tap into existing substations, located in German and Saint Mary’s Townships within Auglaize County, Ohio

    The project will consist of the rebuilding of approximately 12.6 miles of the existing 6630 Amsterdam-St. Mary’s and 6665 St. Mary’s-West Moulton 69kV lines, the replacement of the existing transmission line pole structures, and the addition of the new Amsterdam-West Moulton 138kV circuit on these existing segments, resulting in a 69kV / 138kV double-circuit configuration when complete. The rebuilt line will run 12.6 miles generally along County Roads 33A, 61, 53A, and 66A. The project is needed to support overall reliability of the power system in this area under various operational conditions and to reinforce the electrical supply to the Honda Development and Manufacturing of America (HDMA) that has grown significantly since the original interconnection to the power transmission system.
