A hydropower resource can be evaluated by its available power. Power is a function of the hydraulic head and volumetric flow rate. The head is the energy per unit weight (or unit mass) of water. [5] The static head is proportional to the difference in height through which the water falls. Dynamic head is related to the velocity of moving water.
This is a list of operational hydroelectric power stations in the United States with a current nameplate capacity of at least 100 MW.. The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936.
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity (behind wind power) in the United States. [1] In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2]
Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2] 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 ...

Water is required for all life, but since ancient times, mankind has also employed this natural resource for other specifically human productive uses. Millennia ago man learned to navigate on water, learned to dam and divert it for irrigation and build aqueducts and canals to carry it where possible, and learned to convert the power of moving water to mechanical energy to perform work. [1]
Each unit of power is expected to cost the consumer US$0.049 for the first 10 years of the life of the power station, after which the price will drop down to US$0.020 per unit, for the next 15 years. Three new substations, one each at Karuma, Kawanda and Olwiyo, are part of the construction contract.
Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
