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.

  • How do hydroelectric dams work?

  • Hydroelectric dams work by reserving a river’s water and potential energy. The hydraulic head, created by the depth of the water and the water’s velocity as it travels through the dam’s penstock, enables the turbine in the hydroelectric plant to spin.

  • 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.

  • Where is the water stored in a hydro dam?

  • In the penstock the water is stored where there is usually some sort of gate that separates the reservoir with the intake valve and penstock which controls the amount of water that is allowed to flow through the dam. (3) The intake valve is what leads the water towards the blades of the hydro turbine blades.
