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.

Jan 28, 2012. #9. In comparisons remember coal is about 25,000,000 BTUs per ton, pellets are about 14,000,000 per ton. If coal is 300 per ton and pellets are 200 per ton then 300 of coal is about 350 of pellets for the same BTUs. This does not take into account the efficiencies of the stove. I burn coal and wood.
