Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.

We take a coal price of around 65 / Ton. The cost of coal consumed by 100 MW power plant is ( x 65) 3497 /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) cents per unit. The cost of fuel is the main factor in the cost of a unit of electricity.
