Generation

Power generation is the process of producing electric power from sources of primary energy. Energy resources can be classified in three categories namely renewable, fossil, and nuclear. Within the generation categories renewable comprise of wind, solar, geothermal, biomass, and hydropower. Fossil fuels include coal, petroleum, natural gas For utilities in the electric power industry, generation is the stage prior to the delivery of power to end users (transmission, distribution, etc.) or its storage (using, for example, the pumped-storage method). Electricity generation is carried out in power stations also called power plants.
