Coal fired Plants: Pros and Cons
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 off-peak 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.
Thermal performance study of tower solar aided double reheat coal-fired …
Introduction. Coal-fired power generation is still the main power source all over the world at present [1]. And developing the coal-fired power generation technology with high parameters and large capacity is the crucial method of efficient energy conservation and pollution reduction [2].

Hydroelectric Power: How it Works | U.S. Geological Survey
In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the …

Gas is cheap. With renewables, the "fuel" is free; and all methods of power generation require costly plants and equipment. Coal power plants cannot compete with a combined-cycle natural gas plant and can no longer even compete with wind and solar. Power generators have not built any new coal-fired power plants over the past decade.
