North Country power transmission project gets state approval


A plan to rebuild an 86-mle-long electricity transmission line from a hydropower plant on the St. Lawrence River to a Lewis County substation has won state regulatory approval.

The New York State Public Service Commission approved a certificate of environmental compatibility and public need to the Moess-Adirondack 1 and 2 transmission line plan proposed by the New York Power Authority on Thursday, the commission announced.

The 230-kilovolt transmission lines extend from the Robert Moses Power Dam Switchyard in Massena, St. Lawrence County, to the Adirondack Substation in Croghan. Upgrades to the Moses switchyard and the Adirondack Substation were also in the April 2018 application. The Power Authority, a quasi-public agency created in the mid-20th century to distribute hydropower in western and northern New York, will work nearly entirely within an existing right-of-way it maintains or on other of its property.

The Public Service Commission said the project is necessary to rebuild facilities that are well past their design lives to make them more resilient and reduce maintenance costs.

The proposed transmission lines are needed to deliver
electricity, including carbon-free hydroelectric power, from northern New York to the rest of the state, to help head off widespread outages, and to increase capacity to meet state clean-
energy goals.
