Things Everyone Must Know About A Hydro Power Plant

More than seventy per cent of the surface of the earth is covered with water. This water is present in seas, oceans, rivers, groundwater, rainwater, etc. Water is a renewable resource whose energy can be used to produce electricity. Thermal power plants produce electricity from the energy of fossil fuels such as coal. Similarly, the hydro power plant is used to produce electricity by using the kinetic energy of the flowing water.

Types Of Hydro Power Plant:

Hydro Power Plants constructions are usually over dams. Because they offer a flow of water from a height which can easily run the turbines. They can be of various types, which are as follows:

1. Impoundment Hydropower Plant

To begin with, it is a large Hydro-power plant system that uses a reservoir to store the river water. Then, the stored water can be used to maintain a constant level of reservoir water or to meet the daily electricity demands.

2. Pumped Storage Hydropower Plant

This type of plant integrates a reservoir with a system that can drive water back into a turbine. These types of plants allow re-usage of water for electricity generation. These plants are usually smaller in size than Impoundment Hydro Power Plants.

Moreover, there are several other types of hydro power plants available that are built keeping in mind the needs of the geographical area where they are being installed.

How Does A Hydro Power Plant Produce Electricity?

 As the name suggests, a Hydro Power plant generates electricity by using the energy of flowing water. The pressure created due to the flow of water is used to run turbines which in turn generates electric power. This happens through a series of systematic steps:

  1. First, the water from a dam or other source falls on the blades of a turbine causing the blades to turn with great speed. This motion is similar to the movement of turbine blades when hot steam produced in a thermal power plant is incident on the blades.
  2. In the next step, the turbine spins the generator to produce electric energy.
  3. This electric energy is either stored or made to travel over long distances through electric lines to homes, offices and other places.

Advantages Of Using Hydro-Electric Power

Unlike other natural resources such as coal, petroleum, natural gas, etc. that are exhaustible in nature, the water is a resource that is renewable and inexhaustible. The main advantage of using water resource to generate electricity is that it is a sustainable resource and is non-polluting.

  1. Hydropower is a clean fuel source. Its usage doesn’t release any harmful/poisonous chemicals, gases or pollutants in the environment.
  2. It is a more affordable energy resource than fossil fuels as it relies on the energy of the sun which is the driving force behind the cycle of water.
  3. A Hydro Power Plant facility can assist in flood control and water supply for activities such as irrigation. Moreover, it can provide opportunities for recreational activities such as fishing, swimming, boating, etc.

Disadvantages Of Using Hydroelectric Power

Although hydroelectric power is a clean energy fuel, this doesn’t mean that it cannot have harmful effects on the environment.

  1. Moreover, hydroelectric power plants constructions are over rivers which disrupt aquatic ecosystems of the rivers. Often a huge number of the fishing population gets driven into reservoirs causing huge devastation. This affects the fishes and marine life during the breeding season.
  2. Although, construction of dams requires a huge area of land. Usually, forests are cleared for construction. Hence, this causes bad effects on the natural ecosystem and the natural flora and fauna of the region get affected greatly.
