A Thermal Power Plant converts the heat energy of coal into electrical energy. Coal is burnt in a boiler which converts water into steam. The expansion of steam in turbine produces mechanical power which drives the alternator (generator) coupled to the turbine. Thermal Power Plants contribute maximum to the generation of Power for any country.
