  2. Pondage - Wikipedia

    en.wikipedia.org/wiki/Pondage

    24-hour inflows and plant operation would have a pondage factor of one. If power is used for twelve hours per day and during the inactive hours, relatively all inflows can be stored, then power can be doubled during active hours. In 12 hours there are 43,200 seconds and in 1 acre⋅ft (1,233 m 3) there are 43,560 cu ft (1,233 m 3). This gives ...

  3. 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 ...

  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. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    90–95% (multiply by the energy efficiency of electricity generation to compare with other water-heating systems) Electric heater: Electrical to thermal ~100% (essentially all energy is converted into heat, multiply by the energy efficiency of electricity generation to compare with other heating systems) Others: Firearm: Chemical to kinetic

  6. Power plant engineering - Wikipedia

    en.wikipedia.org/wiki/Power_plant_engineering

    All power plants are created with the same goal: to produce electric power as efficiently as possible. However, as technology has evolved, the sources of energy used in power plants has evolved as well. [1] The introduction of more renewable/sustainable forms of energy has caused an increase in the improvement and creation of certain power ...

  7. Load-following power plant - Wikipedia

    en.wikipedia.org/wiki/Load-following_power_plant

    Load-following power plants can be hydroelectric power plants, diesel and gas engine power plants, combined cycle gas turbine power plants and steam turbine power plants that run on natural gas or heavy fuel oil, although heavy fuel oil plants make up a very small portion of the energy mix. A relatively efficient model of gas turbine that runs ...

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

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

    There are also small and somewhat-mobile forms of a run-of-the-river power plants. One example is the so-called electricity buoy, a small floating hydroelectric power plant. Like most buoys, it is anchored to the ground, in this case in a river. The energy within the moving water propels a power generator and thereby

  9. Pumped-storage hydroelectricity - Wikipedia

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

    The energy storage in gigawatt-hours (GWh) is the capacity to store energy, determined by the size of the upper reservoir, the elevation difference, and the generation efficiency. Countries with the largest power pumped-storage hydro capacity in 2017 [ 65 ]
