In 1961, when the Niagara Falls hydroelectric project went online, it was the largest hydropower facility in the Western world. Today, Niagara is still the largest electricity producer in New York state, with a generating capacity of 2.4 GW. Up to 1,420 cubic metres (380,000 US gal) of water a second is diverted from the Niagara River through conduits under the city of Niagara Falls to the Lewiston and Robert Moses power plants.
