How to Calculate the Coal Quantity Used in a Power Plant

 · Coal trader s web sites give base prices in the international market. 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 100 000 units of electricity. So the cost of coal per unit of electricity is (3497/100 000) 3.5 cents per unit.
