Energy content of coal is given in terms of Kilojoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal. Efficiency Energy conversion takes place in two stages. The first part of the conversion is efficiency of the boiler and combustion.

How to Calculate the Coal Quantity Used in a Power Plant We take a coal price of around 65 \$ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 \$ /hr. A 100 MW unit produces 100000 units of electricity. So the cost of coal per unit of electricity is (3497/100000) 3.5 cents per unit.
