Coal fired Plants: Pros and Cons Bright Hub Engineering

One of the greatest advantages of coal fired plants is reliability. Coal's ability to supply power during peak power demand either as base power or as offpeak power is greatly valued as a power plant fuel. It is with this fact that advanced pulverized coal fired power plants are designed to support the grid system in avoiding blackouts.
