    What are the different types of hydro power plants?

    Date:2018-4-27 11:27

    There are four broad hydro power typologies:

    1.Run-of-river hydro power:

    A facility that channels flowing water from a river through a canal or pen stock to spin a turbine. Typically a run-of-river project will have little or no storage facility. Run-of-river provides a continuous supply of electricity (baseload), with some flexibility of operation for daily fluctuations in demand through water flow that is regulated by the facility.

    2. Pumped-Storage Hydro power:

    Provides peak-load supply, harnessing water which is cycled between a lower and upper reservoir by pumps which use surplus energy from the system at times of low demand. When electricity demand is high, water is released back to the lower reservoir through turbines to produce electricity.

    3. Storage Hydro power:

    Typically a large system that uses a dam to store water in a reservoir. Electricity is produced by releasing water from the reservoir through a turbine, which activates a generator. Storage hydropower provides base load as well as the ability to be shut down and started up at short notice according to the demands of the system (peak load). It can offer enough storage capacity to operate independently of the hydrological inflow for many weeks or even months.

    4. Offshore Hydro power:

    A less established but growing group of technologies that use tidal currents or the power of waves to generate electricity from seawater.
