What is the function of reservoir in hydroelectric power plants?

A hydroelectric reservoir is a large collection of water behind a hydroelectric dam that makes use of potential energy of water for generating electricity. This water is held back by the dam and a small amount is allowed to fall down the base of the dam to generate electricity when it is needed.

What are the functions of reservoir?

In a system, all basic functions of a reservoir can be made use of: storage, water conservation, flood control, water treatment, and aquatic environment. Reservoir systems can be either single- or multi-purpose systems.

What is a hydroelectric reservoir?

The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.

What are three benefits of a hydroelectric reservoir?

Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water.

What is reservoir in hydrothermal power plant?


The geothermal reservoir is an aquifer with hot water or steam. A geothermal heating system is illustrated in Figure 16.1. A production well is used to withdraw hot water from the geothermal reservoir, and an injection well is used to recycle the water. Recycling helps to maintain reservoir pressure.

What is the function of reservoir in nutrient cycle?

The function of the ‘reservoir’ is to meet the deficit which occurs due to an imbalance in the rate of influx and efflux.

What are 4 functions of a hydraulic reservoir?

Hydraulic System Components

  • Reservoir. The purpose of the hydraulic reservoir is to hold a volume of fluid, transfer heat from the system, allow solid contaminants to settle and facilitate the release of air and moisture from the fluid.
  • Pump. …
  • Valves. …
  • Actuators. …
  • Vane Pumps. …
  • Piston Pumps. …
  • Gear Pumps. …
  • Hydraulic Fluids.

Where is hydroelectric used?

Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17% (International Energy Agency) of total electricity production. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).

Is hydro electricity Green?

But new information on the role of hydro-dams and reservoirs as a source of significant greenhouse gas emissions has made clear that they are also not the “green,” carbon-neutral sources of energy we once thought—and hoped—they were.

What kind of hydroelectric power plant does not require a reservoir?

Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided.

What type of energy is stored in a reservoir?

The water in a reservoir behind a hydropower dam is another example of potential energy. The stored energy in the reservoir is converted into kinetic energy (motion) as the water flows down a large pipe called a penstock and spins a turbine.
