The price of coal can depend on the type of transaction. Most of the coal sold for electric power generation is sold through long-term contracts. Supplies are supplemented with spot purchases of coal. In addition to producing electricity, coal is also used to produce coal coke, or coke, which is used in smelting iron ore to make steel.
