Coalfired power. In general, two different methods are used to change coal plants to natural gas. The first method is to remove the coalfired power plant and replace it with a new natural gas combined cycle plant (NGCC). Meanwhile, the second method is to convert the boiler of a coal steam plant to burn other types of fuel, such as natural gas.
