Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of {{convert|2675|MW|abbr=on}}. Named for New York city planner Robert Moses, the plant was built to replace power production after a nearby hydroelectric plant collapsed in 1956. It stands across the river from Sir Adam Beck Hydroelectric Power Stations in Queenston, Ontario, Canada. HistoryOriginsThe land that the Robert Moses Niagara Power Plant occupies has a long history of use. In 1805, Augustus and Peter Porter of Buffalo, New York, purchased the American Falls from New York in a public auction, and later acquired the rights to the eastern rapids above the falls as well, but died before they could bring their vision of a canal and power plant to reality. Several other companies later attempted similar projects without success.[1] In 1853, the Niagara Falls Hydraulic Power and Manufacturing Company was chartered; in 1861, it completed a {{convert|35|ft|adj=on|abbr=on}} wide and {{convert|8|ft|adj=on|abbr=on}} deep canal. The powerhouse finally opened in 1874, but produced little electricity even by the standards of the day.[1] In 1877, Jacob F. Schoellkopf purchased the canal, along with the water and power rights, for $71,000. He improved the canal and put the powerhouse to commercial use. In 1881, his company completed Schoellkopf Power Station No. 1; it would operate until 1904. In 1891, Schoellkopf Power Station No. 2 opened directly in front of the original, in the gorge below the falls, with a higher {{convert|210|ft|adj=on|abbr=on}} drop. In 1914 and 1918, the company built Schoellkopf Stations No. 3A and 3B respectively.[2] In 1886, the competing Niagara Falls Power Company, owned by the Cataract Construction Company, built the Adams Power Plant. Between 1900 and 1904, the company built the Powerhouse No. 2, bringing its total generators to 11.[2] In 1918, World War I led the power companies to merge into the Niagara Falls Power Company. From 1921 to 1924, the company built Schoellkopf Station No. 3C next to the previous ones. It contained three 25 Hz generators with a total capacity of {{convert|210000|HP|MW|disp=flip|abbr=on}},[2] bringing the Schoellkopf Power Stations to 19 generators with a capacity of {{convert|450000|HP|MW|disp=flip|abbr=on}}. On June 7, 1956, water seeping into a back wall caused the collapse of two-thirds of Schoellkopf Power Station No. 3b and 3c, killing one worker and causing an estimated $100 million in damage.[3] Construction{{main|Schoellkopf Power Station}}To replace the antiquated and now partially destroyed Schoellkopf power stations, the New York Power Authority (NYPA) planned an $800 million power plant that would produce 2.4 GW. During planning, it was called the Niagara Power Project; later, it was named for NYPA head Robert Moses. In 1957, the United States Congress approved the project. Construction began that year, although its completion would require the NYPA to gain the rights to {{convert|550|acre}} of Tuscarora Indian Reservation for a new {{convert|1900|acre|adj=on}}, {{convert|22|e9USgal|m3|adj=on}} reservoir. This it did in 1960, through a United States Supreme Court decision, the Federal Power Commission v. Tuscarora Indian Nation.[1][4] During construction, over 12 million cubic yards of rock were excavated and twenty workers died. Construction was complete in 1961.[1] When it opened in 1961, it was the Western world's largest hydropower facility.{{Citation Needed|date=July 2018}} The generation facilities were listed on the National Register of Historic Places in 2017.

Water enters the forebay via tunnels from the Niagara River controlled via the International Control Dam upstream of the natural falls. Water in the forebay is then either pumped up into the upper reservoir or immediately sent down over the escarpment downstream of the natural falls into the Robert Moses Power Station turbines. The Lewiston Pump-Generating Plant {{coord|43|08|33|N|79|01|18|W|name=Lewiston Pump-Generating Plant}} houses 12 electrically powered pump-generators that can generate a combined {{convert|240|MW|abbr=on}} when water in the upper reservoir is released. At night, a substantial fraction ({{convert|600,000|USgal|m3|abbr=on}} per second) of the water in the Niagara River is diverted to the forebay by two {{convert|397|ft|adj=on|abbr=on}} tunnels.[6] Electricity generated in the Moses plant is used to power the pumps to push water into the upper reservoir behind the Lewiston Dam. The water is pumped at night because the demand for electricity is much lower than during the day. In addition to the lower demand for electricity at night, less water can be diverted from the river during the day because of the desire to preserve the appearance of the falls. During the following day, when electrical demand is high, water is released from the upper reservoir through the pump-generators in the Lewiston Dam. The water then flows into the forebay, where it falls through the turbines of the Moses plant. Some would say that the water is "used twice". This arrangement is a variant of what is called pumped-storage hydroelectricity. Engineers copied what had been built by Ontario Hydro, across the river, when a similar system was built during construction of the Sir Adam Beck generating station II in the 1950s. This system allows energy to be stored in vast quantities. At night, the potential energy in the diverted water is converted into electrical energy in the Moses plant. Some of that electrical energy is used to create potential energy when the water is pumped into the reservoir behind the Lewiston Dam. During the day, part of the potential energy of the water in the Lewiston reservoir is converted into electricity at the Lewiston Dam, and then its remaining potential energy is captured by the Moses Dam, which is also capturing the potential energy of the water diverted from the river in real-time. Beginning in 2012 and continuing through 2020, the pump-generating plant will be undergoing a $460 million modernization that will increase the plant's efficiency and service life. The Robert Moses Plant was refurbished in 2006.[7] Contamination of the site areaDuring the mid-1980s, the New York Power Authority began an expansion project at the site, known as FERC (Federal Energy Regulatory Commission) Project 2216. Soon after, the project was halted due to discovery of hazardous chemicals such as dioxins, which had been dumped underground by chemical companies which had owned the land previously. A civil lawsuit was filed in the State of New York against the New York Power Authority, Occidental Petroleum, Hooker Chemicals, Bechtel Corporation, and Parsons Brinckerhoff, which was settled out of court in 1999.[8] Subsequent testing near the Lewiston Reservoir near the project still confirms mercury and organic contamination which restricts the consumption of fish.[9] Niagara Power Visitors CenterThe Niagara Power Visitors Center is located four miles downstream of Niagara Falls, with an observation deck along Niagara Gorge. The Center features interactive exhibits about hydroelectricity and its history in the Niagara Frontier. See also{{stack|{{Portal|New York|Water|Renewable energy}}}}
