Thermal Power Plants in India In today’s sky, electricity has become an important part of our life. Where everything from lights to fans, from phones to ACs runs on electricity. To supply this electricity, India takes help of various sources, one of the important sources of which is – thermal power plants. These plants produce electricity by using heat. Let us take a little deeper to understand how thermal power plants work and why they are so important for India.
A thermal power plant, also known as a thermal power station, is a type of power generation plant where electricity is generated using thermal energy. These plants mostly use non-renewable sources such as coal, oil, gas or nuclear fuel. The operation of a thermal power plant is simple and efficient, in which water is converted into steam by burning fuel. This steam is passed through a turbine, which is connected to a generator and electricity is generated in the process.
What is a Thermal Power Plant?
A thermal power plant is a system set up to convert thermal energy into electrical power/energy for domestic and commercial use. During electricity production, steam-driven turbines convert heat into mechanical and then electrical power. In a thermal power plant, heat energy produced through the combustion of solid fuel (often coal) is used to generate steam at high pressure and temperature. The turbine shaft connected to the generator rotates with the help of this steam. The generator then converts the kinetic energy of the turbine’s rotor into electrical energy.
How Does a Thermal Power Plant Work?
Thermal power plants basically work by converting heat into electricity. It involves several steps:
1.Fuel Combustion: Fuels such as coal, natural gas or oil are burned in a boiler. The heat from burning heats water to form steam.
2.Steam Generation: The hot steam is taken to the turbine. Several blades fitted in the turbine rotate due to the pressure of steam.
- 3.Conversion of Mechanical Energy into Electrical Energy: The rotating turbine is connected to a generator. In the generator, mechanical energy is converted into electrical energy using magnets and conductors.
- 4.Electricity Distribution: Finally, the electricity produced is transmitted to distant places by stepping up or down the voltage with the help of transformers. This is a simple process, but in reality thermal power plants are quite complex. It uses pollution control systems to reduce pollution and various technologies to increase efficiency.
Types of Thermal Power Plants in India
There are many types of thermal power plants used for electricity generation in India. Let us know a little about these different types:
1.Coal-Based Thermal Power Plant: These are the most common thermal plants in India. In these, steam is produced by burning coal, and then electricity is generated from this steam. However, burning coal causes pollution, so the government is promoting the adoption of clean coal technology.
2.Gas-Based Thermal Power Plant: These plants use clean fuel like natural gas. Burning gas causes less pollution than coal, but natural gas is a relatively expensive fuel.
3.Diesel-Based Thermal Power Plant: These plants are usually small and are used to supply electricity in emergency situations or remote areas. Diesel fuel is even more expensive than other options, so they are rarely used.
4.Geothermal Thermal Power Plant: These plants generate electricity using the heat present within the earth. Geothermal energy is not used much in India yet, but it can play an important role as a clean energy option in the future.
5.Biomass-Based Thermal Power Plant: These plants generate electricity by burning organic matter such as agricultural residues or wood chips. Biomass is a renewable fuel, but it can cause some amount of pollution when burned.
As we just discussed, there are three main types of thermal power plants that are used to generate electricity in India. Let’s take a look at the installed capacity data as of January 2021:
Coal: 206404.50 MW – As we know, coal-based plants are the most common in India, and they also represent the largest share of the total capacity.
Gas: 24956.51 MW – Cleaner than coal, gas-based plants account for a significant share of the total capacity.
Liquid fuel (diesel): 509.71 MW – As we know, diesel is the most expensive fuel, so it is used less frequently and its contribution to the total capacity is quite low.
If we look at the overall capacity, the total installed capacity of all thermal plants in India as of January 2021 was 231870.72 MW. That’s quite a huge amount! And more importantly, the power produced by these plants is 71% of the total power generation of the country. This shows how important role thermal plants play in power generation in India.
