Micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. The installation is often [when?] [where?] just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing. In low head sites, [example needed] generally water wheels and Archimedes' screws ...
An example of a small hydro power plant, Sveta Petka. A final noted advantage of small hydro over larger hydropower developments or fossil fuel plants is an element of environmental justice. In a number of communities which lack essential electricity access small hydro offers a reliable and clean source of electricity.
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

An example would be the 1995 1,436 MW La Grande-1 generating station. Previous upstream dams and reservoirs were part of the 1980s James Bay Project. There are also small and somewhat-mobile forms of a run-of-the-river power plants. One example is the so-called electricity buoy, a small floating hydroelectric power plant. Like most buoys, it is ...
The Three Gorges (22,500 MW - 32 × 700 MW and 2 × 50 MW) is operated jointly with the much smaller Gezhouba Dam (2,715 MW), the total generating capacity of this two-dam complex is 25,215 MW. The Itaipu on the Brazil–Paraguay border has 20 generator units with overall 14,000 MW of installed capacity, however the maximum number of generating ...
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]

The largest hydroelectric power station is the Three Gorges Dam in China, rated at 22,500 MW in total installed capacity. After passing on 7 December 2007 the 14,000 MW mark of the Itaipu Dam, the facility was ranked as the largest power-generating facility ever built. The dam is 181 m (594 ft) high, 2,335 m (7,661 ft) long and 115 m (377 ft ...
