B. Jarvis Plant in Oneida County and the Vischer Ferry Plant in Schenectady and Saratoga counties. Gas-fired generation Other generating facilities include two highly efficient natural gas-fueled combined cycle power plants: the 150-MW Richard M. Flynn Power Plant, in Holtsville, Long Island and a 500-MW facility, in Astoria, Queens. Additionally, NYPA operates ten small power plants also fuelled by natural gas. Those sites – six in New York City and one in Long Island – have combined output of 460-MW. Electric transmission lines The hub of NYPA’s statewide power transmission facilities is the Frederick R. Clark Energy Center, in Marcy, New York. 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 transmission project, that follows an underground and underwater path from Westchester County to Long Island. New York State Canal Corporation The New York Power Authority has been financially responsible for the New York State Canal Corporation since April 2016 and has owned it since January 1, 2017. History New York Governor Roosevelt signed the Power Authority Act into law on April 27, 1931 that established the Power Authority of the State of New York (PASNY); the name was later changed to New York Power Authority (NYPA). St. Lawrence-Franklin D. Roosevelt Power Project The International Joint Commission granted its approval for a cross-border construction project in 1952. In 1953, the Federal Power Commission issued a license for NYPA to develop the U.S. portion of a power dam crossing the Canada–US border. On May 13, 1954, President Dwight D. Eisenhower signed legislation that cleared the way for construction of both a hydroelectric facility and the St. Lawrence Seaway. First power was achieved in July 1958, and on June 27, 1959, Queen Elizabeth II and Vice President Richard M. Nixon formally dedicated the St. Lawrence Project as a symbol of international cooperation. In 1981, NYPA’s half of the cross-border power dam was renamed the St. Lawrence-Franklin D. Roosevelt Power Project in honor of the man who founded the Power Authority half a century earlier. Niagara Power Project In 1956, a rock slide destroyed most of the Niagara Mohawk Power Corporation's Schoellkopf hydropower plant, resulting in a power shortage that endangered thousands of local manufacturing jobs.
