The plant, still under construction, is designed to use a soft form of coal called lignite in a gasification process to generate power.

Legal challenges brought by the Sierra Club have led regulators to block Mississippi Power Co. from billing customers for the costs so far, although the Southern Co. subsidiary got closer to that goal with a favorable lower court ruling earlier this month.
Southern CEO Thomas Fanning stands by the plant. He says Southern's own technology will mitigate its environmental impact and the need to exploit coal as a hedge against uncertainties in the future cost of natural gas, which is currently cheap and abundant.
