An additional defining feature of small hydro is known as run-of-river, or that the physical impact of the project is relatively minuscule compared to major hydroelectric dams which require a water storage lake. Little water is stored behind the project, if at all, and the river is usually able to continue flowing.
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.
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 anchored to the ground, in this case in a river.
Urumi 1 Weir is small diversion dam constructed across Poyilingalpuzha in Koodaranji village of Kozhikode district in Kerala, India. [1] This weir is constructed for power generation in a Small Hydro Electric Project and is constructed across the Poylingalpuzha which is a tributary of Chaliyar river .
At the time it was by far the largest hydroelectric plant in the state. [1] In 1924 it was rebuilt as a 60 cycle plant with 15,000 kilowatts (up from the original 10,500 kW). [2] In 1957 it was raised to regulate the flow from the larger Buford Dam, 36 miles (58 km) upstream, in order to give Atlanta water during the hours it was needed most. [3]
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.

The Colley Wobbles Power Station is a hydroelectric power facility located approximately 30 km east of Dutywa in the Amathole District Municipality of the Eastern Cape of South Africa. Water is drawn from behind a dam on the Mbhashe River and diverted through a penstock to the Colley Wobbles Power Station. The power station discharges into the ...
Micro hydro in northwest Vietnam. Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. . Installations below 5 kW are called pico hydr
