Small power plant of Licq-Athérey (Pyrénées-Atlantiques, France). An 1895 hydroelectric plant near Telluride, Colorado.. Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. [1]

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. Since then numerous other hydroelectric power stations have surpassed the 1,000 MW threshold, most often through the expansion of existing hydroelectric facilities.
In relation to rural development, the simplicity and low relative cost of micro hydro systems open up new opportunities for some isolated communities in need of electricity. With only a small stream needed, remote areas can access lighting and communications for homes, medical clinics, schools, and other facilities. [16]
The upper reservoir can hold about 1.5 billion US gallons (4,600 acre-feet; 5.7 million cubic metres) of water behind a wall nearly 100 feet (30 m) tall. [12] It sits 760 feet (230 m) above the 450 MW hydroelectric plant, which gives it a greater head than that of Hoover Dam.
Although a dam-like structure is required, no area is enclosed, and therefore most of the benefits of 'damless hydro' are retained, while providing for vast amounts of power generation. Low-head hydro is not to be confused with "free flow" or "stream" technologies, which work solely with the kinetic energy and the velocity of the water.
This is a list of electricity-generating power stations in the U.S. state of Utah, sorted by type and name.In 2022, Utah had a total summer capacity of 9,627 MW through all of its power plants, and a net generation of 39,386 GWh. [2]
The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
