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.

Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).

Charcoal is stable and durable. It is capable of persisting in the soil for a very long time. Of course how long may depend on the type of charcoal, conditions, soil etc. but it is no doubt capable at times of persisting for millennia. While some of the minerals in ashes may be persistent, ash is essentially a very short term fertilizer.
