NYPA’s high-voltage transmission assets include a 765-kilovolt (kV) line that stretches more than 100 miles from the Canada–US border to the Clark Energy Center and almost 1,000 miles of 345-kV power lines that crisscross New York State, including the Marcy South line and a 26 miles transmission project, that follows an underground and underwater path from Westchester County to Long Island.
