Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, 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 ...
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]
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.
Opened in 2011, this OWC power plant can generate approximately 300 kW at proper conditions (enough to power 250 houses) with its 16 Wells turbines. The turbines were provided by Voith, a company which specializes in hydropower technology and manufacturing. [8] The collecting chambers and turbines are housed in a breakwater.
Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
Work began in the second half of 2013 and was expected to last five years. Construction costs were to be jointly funded by the Ugandan and Chinese governments. [19] [20] [21] In June 2014, the Exim Bank of China committed in writing to fund 85 percent of the construction costs, in the form of a concessionary loan repayable in five years. The ...
The Nelson River DC Transmission System, also known as the Manitoba Bipole, is an electric power transmission system of three high voltage, direct current lines in Manitoba, Canada, operated by Manitoba Hydro as part of the Nelson River Hydroelectric Project.
