Oct 15, 2009  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.
