  2. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    The first Edison hydroelectric power station, the Vulcan Street Plant, began operating September 30, 1882, in Appleton, Wisconsin, with an output of about 12.5 kilowatts. [16] By 1886 there were 45 hydroelectric power stations in the United States and Canada; and by 1889 there were 200 in the United States alone. [13]

  3. Pumped-storage hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Pumped-storage...

    In this regard, a storm-water basin has been concretely implemented as a cost-effective solution for a water reservoir in a micro-pumped hydro energy storage. [7] Such plants provide distributed energy storage and distributed flexible electricity production and can contribute to the decentralized integration of intermittent renewable energy ...

  4. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...

  5. Power plant efficiency - Wikipedia

    en.wikipedia.org/wiki/Power_plant_efficiency

    The higher the heat rate (i.e. the more energy input that is required to produce one unit of electric output), the lower the efficiency of the power plant. The U.S. Energy Information Administration gives a general explanation for how to translate a heat rate value into a power plant's efficiency value. [4] Most power plants have a target or ...

  6. Capacity factor - Wikipedia

    en.wikipedia.org/wiki/Capacity_factor

    The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind, the sun or hydro-electric installations. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of ...

  7. Small hydro - Wikipedia

    en.wikipedia.org/wiki/Small_hydro

    Small power plant of Licq-Athérey (Pyrénées-Atlantiques, France). 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]

  8. Draft tube - Wikipedia

    en.wikipedia.org/wiki/Draft_tube

    The draft tube works by converting some of the kinetic energy at the exit of the turbine runner into the useful pressure energy. [2] Using a draft tube also has the advantages of placing the turbine structure above the tail race so that any required inspections can be made more easily and reducing the amount of excavation required for construction.

  9. Energy return on investment - Wikipedia

    en.wikipedia.org/wiki/Energy_return_on_investment

    The issue is still subject of numerous studies, and prompting academic argument. That's mainly because the "energy invested" critically depends on technology, methodology, and system boundary assumptions, resulting in a range from a maximum of 2000 kWh/m 2 of module area down to a minimum of 300 kWh/m 2 with a median value of 585 kWh/m 2 according to a meta-study from 2013.
