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.

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.
In Switzerland one study suggested that the total installed capacity of small pumped-storage hydropower plants in 2011 could be increased by 3 to 9 times by providing adequate policy instruments. [42] Using a pumped-storage system of cisterns and small generators, pico hydro may also be effective for "closed loop" home energy generation systems ...
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 ...
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 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.
