  2. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    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.

  3. Upper Kotmale Dam - Wikipedia

    en.wikipedia.org/wiki/Upper_Kotmale_Dam

    The 220kV transmission line of the Upper Kotmale Hydro-power Project connects the power station located at Niyamgamdora, Kotmale, to the national grid via Kotmale switch yard located in Atabage, Gampola. The line consists of 45 towers and has a length of 15.5 km. The double circuit transmission line has a capacity of 220 MW per circuit.

  4. Hydrostatic head - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_head

    As shown in this drawing, the hydrostatic head is the vertical distance between the water level in the reservoir and the turbine that is turned by the flowing water. When generating hydropower, the head is the distance that a given water source has to fall before the point where power is generated. Ultimately the force responsible for ...

  5. Run-of-the-river hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Run-of-the-river...

    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.

  6. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    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 15% of the world's electricity, almost 4,210 TWh in 2023, [ 1 ] which is more than all other renewable sources combined and also ...

  7. Hydraulic engineering - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_engineering

    Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges ...

  8. List of hydroelectric power stations in the United States

    en.wikipedia.org/wiki/List_of_hydroelectric...

    This is a list of operational hydroelectric power stations in the United States with a current nameplate capacity of at least 100 MW. 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 ...

  9. Conduit hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Conduit_hydroelectricity

    Conduit hydroelectricity (or conduit hydropower) is a method of using mechanical energy of water as part of the water delivery system through man-made conduits to generate electricity. Generally, the conduits are existing water pipelines such as in public water supply. [1] Some definitions expand the definition of conduits to be existing ...
