Since it has a low price, and good regulation, cross-flow turbines are mostly used in mini and micro hydropower units of less than one thousand kW and with heads less than 200 m (660 ft). Particularly with small run-of-the-river plants , the flat efficiency curve yields better annual performance than other turbine systems, as small rivers ...

Three Gorges Dam (left), Gezhouba Dam (right). This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed.
Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, [1] which is more than all other renewable sources combined and also more than nuclear power. [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]
US EIA monthly capacity factors 2011-2013. The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1]

Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy production.
The European Network of Transmission System Operators for Electricity distinguishes run-of-the-river and pondage hydropower plants, which can hold enough water to allow generation for up to 24 hours (reservoir capacity / generating capacity ≤ 24 hours), from reservoir hydropower plants, which hold far more than 24 hours of generation without ...
