Public Hearings Scheduled for NYPA Transmission Line Rebuild

Dec. 5, 2018
NYPA proposes to divide the project into two phases.

The New York State Public Service Commission held public statement hearings in the Town of Croghan, Lewis County and the Towns of Canton and Massena, St. Lawrence County, to receive comments on a request by the New York Power Authority to rebuild its existing 230 kV Moses-Adirondack 1 and 2 transmission lines. The transmission lines extend approximately 86 miles from NYPA's Robert Moses Power Dam Switchyard in the Town of Massena, St. Lawrence County, to the Adirondack Substation in the Town of Croghan, Lewis County.

NYPA proposes to divide the project into two phases. Phase One would consist of replacing 78 miles of the two lines currently configured as single circuits on separate wooden H-frame structures with two new single-circuit lines on steel monopoles. Although NYPA intends to design and construct the transmission lines with the capacity to operate at 345 kV, the initial operating voltage would be 230 kV.

Phase Two would involve replacing the remaining length of the transmission lines with two single circuits on steel monopoles and upgrading the Moses Switchyard and the Adirondack Substation to operate at 345 kV. Prior to commencing Phase Two, NYPA intends to submit an Environmental Management and Construction Plan and petition to amend the certificate to permit the project to operate at 345 kV. Except for an approximately one-mile reroute at the State University of New York at Canton campus, NYPA proposes to construct the project entirely within an existing right-of-way that it maintains.

The application may be viewed at www.dps.ny.gov (search using the case number) or at public libraries in the following municipalities: Canton, Croghan, Edwards, Hermon, Harrisville, Massena, Madrid, Norfolk, Potsdam and Russell.
