While containing less sulfur, PRB coal contains more water, generates less heat and burns less efficiently than the type of coal it replaced. In fact, though overall emissions have been reduced, the plant now requires more throughput to ensure the same generating capacity. Even more vexing, due to several of the inherent properties of PRB coal, it is prone to sudden, spontaneous combustion.
