Energy resources and list of power plant in tamil nadu


Resources from which energy can be obtained for heating and lighting are called energy resources.

They are divided mainly into two types

1. Conventional Power Resources
2. Non-Conventional Power Resources

Conventional power resources

Conventional source of energy are those which have been traditionally used by mankind for a long time. It usually includes fossil fuels like coal, natural gas, oil as well as nuclear power.

There are three major conventional energy sources :

  • Thermal Power Resources
  • Hydel Power Resources
  • Atomic Power Resources

Thermal power resources

Power is generated from nonrenewable energy socrces such as coal, oil and Natural gas is known as thermal power.

Thermal power is produced by heating the water. The steam thus formed spins the turbine to produce electricity.

1 Neyveli Lignite Corporation Cuddalore Coal 2490
2 North Chennai Thermal Power Unit-I Thiruvallur Coal 1200
3 Thuthukudi Thermal Power Plant Thuthukudi Coal 1000
4 Mettur Thermal Power Station Thuthukudi Coal 1000


Hydropower Energy

Hydro power has been with humanity for a long time. Energy in a rushing river is captured through a wheel as mechanical energy.

Atomic power station

Atomic energy is the energy produced from a nuclear reaction, a process in which two nuclei or nuclear particles collide, to produce electrical energy by nuclear reactors.

S.No Name of the plant Capacity in MW
1 Kalpakkam 500 MW
2 Kudankulam 2000 MW



Non-Conventional Power Resources

Non-conventional power Resources are known as renewable resources. Sun is the biggest source of non-conventional energy. Energy is in the form of photos. India receives abundant sunlight for about 250-300 days in a year. The non-conventional energy resources are :

  • Solar Energy
  • Wind Energy
  • Tidal Energy
  • Geo-thermal Energy
  • Bio-fuel Energy
  • Energy from Baggasse


Solar Energy

Solar power is generated from sunlight. This can be used as direct power with photovoltaic (PV) cells, or indirect with concentrating solar power (CSP), Sun's energy is focused to boil water is then used to generate power.

Wind Passes

Wind power is the conversion of wind energy into a useful form of energy. It is generated using wind mills and wind pumps for pumping water or drainage and used to propel ships.
