Best answer


A hydroelectric damrelies on water flowing through a turbine to create electricity to be used on the grid. In order to store energy for use at a later time, there are a number of different projects that use pumps to elevate water into a retained pool behind a dam 鈥?creating an on-demand energy source that can be unleashed rapidly.

  • What type of energy is produced from a dam?

  • Hydroelectric Dam. Hydroelectric dams are a very common form of hydroelectric generation used today and usually consists of large turbines that require a high volume of water flow. Hydroelectric dams use a reservoir of water to capture and flow water through a hydro turbine generator to create electricity.

  • How does a hydroelectric power plant store energy?

  • Pumped hydroelectric storage facilities store energy in the form of water in an upper reservoir, pumped from another reservoir at a lower elevation. During periods of high electricity demand, power is generated by releasing the stored water through turbines in the same manner as a conventional hydropower station.

  • How are dams used to control river flow?

  • In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding. In some rivers, small scale dams known as weirs are built to control and measure water flow.
