v. t. e. 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 ]
The Beles Hydroelectric Power Plant, sometimes referred to as Beles II or Tana Beles, is a run-of-the-river [ 1] hydroelectric power plant in Ethiopia near Lake Tana. The power plant receives water from the lake through the Tana-Beles interbasin transfer and after utilizing it to produce electricity, the water is then discharged into the Beles ...
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage.
The Bath County Pumped Storage Station is a pumped storage hydroelectric power plant, which is described as the "largest battery in the world", [3] with a maximum generation capacity of 3,003 MW, [4] an average of 2,772 MW, [3] and a total storage capacity of 24,000 MWh. [3] The station is located in the northern corner of Bath County, Virginia ...
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] Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further ...
The Three Gorges Dam in Central China is the world's largest power-producing facility of any kind. Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 14% of the world's electricity, almost 4,210 TWh in 2023, [1] which is more than all other renewable sources combined and also ...
The pumped-storage hydroelectric scheme consists of an upper and a lower dam 4.6 kilometres (2.9 mi) apart and is connected to a power station by tunnels. The power station uses 4 Francis pump turbines rated at 333 MW each, giving it a total rating of 1332 MW installed capacity.
Old Pelton wheel from Walchensee Hydroelectric Power Station, Germany. The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [ 1 ][ 2 ] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot ...
