Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods.
Grand Coulee Dam is a concrete gravity dam on the Columbia River in the U.S. state of Washington, built to produce hydroelectric power and provide irrigation water. Constructed between 1933 and 1942, Grand Coulee originally had two powerhouses. The third powerhouse ("Nat"), completed in 1974 to increase energy production, makes Grand Coulee the largest power station in the United States by nameplate capacity at 6,809 MW.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
Indian Point Energy Center (I.P.E.C.) is a now defunct three-unit nuclear power station located in Buchanan, just south of Peekskill, in Westchester County, New York. It sits on the east bank of the Hudson River, about 36 miles (58 km) north of Midtown Manhattan. The facility permanently ceased power operations on April 30, 2021. Before its closure, the station's two operating reactors generated about 2,000 megawatts (MWe) of electrical power, about 25% of New York City's usage. The station is owned by Holtec International, and consists of three permanently deactivated reactors, Indian Point Units 1, 2, and 3. Units 2 and 3 were Westinghouse pressurized water reactors. Entergy purchased Unit 3 from the New York Power Authority in 2000 and Units 1 and 2 from Consolidated Edison in 2001.
The James A. FitzPatrick (JAF) Nuclear Power Plant is located in the Town of Scriba, near Oswego, New York, on the southeast shore of Lake Ontario. The nuclear power plant has one General Electric boiling water reactor. The 900-acre (360 ha) site is also the location of two other units at the Nine Mile Point Nuclear Generating Station.
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand.
Long Island Power Authority is a municipal subdivision of the State of New York that owns the electric transmission and electric distribution system serving all of Long Island and a portion of New York City known as the Rockaways. LIPA was originally created under the Long Island Power Act of 1985 to acquire the Long Island Lighting Company (LILCO)'s electric and natural gas infrastructure after the cancellation of the Shoreham Nuclear Power Plant. LIPA acquired LILCO's transmission system in May 1998, while the remainder of LILCO's natural gas-related infrastructure merged with Brooklyn Union Gas to form KeySpan Energy.
Sir Adam Beck Hydroelectric Generating Stations are two hydroelectric generating stations in Niagara Falls, Ontario, Canada. Sir Adam Beck Generating Station I, Sir Adam Beck Generating Station II and the Sir Adam Beck Pump Generating Station are all owned by Ontario Power Generation. Following the development of several smaller generating stations around Niagara Falls in the late 19th and early 20th centuries, the Province of Ontario authorized the construction of the first major publicly owned generating station in the province. At the time it was built, it was the largest hydroelectric generating station in the world.
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. 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 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and a capacity factor of 71.9%.
The Blenheim–Gilboa Pumped Storage Power Station is a pumped-storage hydroelectricity plant in the Catskill Mountains of New York State. The plant is part of the New York Power Authority, and can generate over 1,100 megawatts (1,500,000 hp) of electricity. It is used daily to cover peak demand. There are two reservoirs that are involved in the project, both with a capacity of 5 billion US gallons (19,000,000 m3); one at the foot of Brown Mountain in the Schoharie Valley, and another one at the top of the mountain. The power station has an accumulated capacity of about 12,000 megawatt-hours (43,000 GJ) after storing up to 17,000 megawatt-hours (61,000 GJ).
Ontario Power Generation Inc. (OPG) is a Crown corporation and "government business enterprise" that is responsible for approximately half of the electricity generation in the province of Ontario, Canada. It is wholly owned by the government of Ontario. Sources of electricity include nuclear, hydroelectric, wind, gas and biomass. Although Ontario has an open electricity market, the provincial government, as OPG's sole shareholder, regulates the price the company receives for its electricity to be less than the market average, in an attempt to stabilize prices. Since 1 April 2008, the company's rates have been regulated by the Ontario Energy Board.
New York has 2,192 MW of installed wind power capacity as of 2022. Most of New York's wind power is located in upstate New York as onshore wind farms. New York has set a goal of developing 9,000 MW of offshore installed wind power capacity by 2035 that will power an estimated 6 million homes. As of October 2022, New York has five offshore wind farms in development with approximately 4,300 MW installed capacity.
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity in the United States. In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity.
The Grand River Dam Authority (GRDA) is an agency of the state of Oklahoma created to control, develop, and maintain the Grand River waterway. It was created by the Oklahoma state legislature in 1935, and is headquartered in Tulsa, Oklahoma. GRDA was designed to be self-funding from the sales of electricity and water. The state of Oklahoma was to provide no funding from taxes. The Authority was authorized to issue revenue bonds to fund large-scale capital investments.

The Moses-Saunders Power Dam, short for Robert Moses-Robert H. Saunders Power Dam, is a dam on the Saint Lawrence River straddling the border between the United States and Canada. It is located between Massena in New York and Cornwall in Ontario. The dam supplies water to two adjacent hydroelectric power generating stations, the United States' 912 MW St. Lawrence-Franklin D. Roosevelt Power Project and Canada's 1,045 MW R.H. Saunders Generating Station. Constructed between 1954 and 1958 as part of the larger Saint Lawrence Seaway project, the dam created Lake St. Lawrence. Aside from providing significant amounts of renewable power, the dam regulates the St. Lawrence River and affords passage for the navigation of large vessels. Despite the enormous economic advantages to the dam, it required the relocation of 6,500 people and caused harm to the surrounding environment. Efforts have been made over the years to improve shoreline and fish habitats.
