A power plant is used to generate electricity from various renewable energy sources as well as conventional sources of energy. A hydro electric power plant makes use of running water to generate electricity or hydropower. Wind turbines that convert wind energy to electricity are used in wind farms. But the majority of power plants run on steam. Steam as a geothermal power product is used to run turbines that in turn power a generator to produce electricity. The steam used is obtained from geothermal reservoirs in the earth to produce electricity.
There are three types of geothermal power plants that are used to generate electricity that can meet the power needs of a rural or urban area. A dry steam geothermal power plant uses steam that is directly pumped from underground wells into the power plant as a geothermal power product. The steam is then used to drive a turbine and generator unit to produce electricity.
Flash steam geothermal power plant uses geothermal reservoirs as the geothermal power product to get geothermal energy. The Hot water from the geothermal reservoirs moves upwards and a small part of it condenses to form steam. Water and steam are separated in the power plant and the steam is used to run a turbine and a generator that produce electricity.
Binary cycle geothermal power plants use water as a geothermal power product. A working fluid which is usually an organic compound is heated by the hot water. The heated working fluid changes to steam and is used to run a turbine to produce electricity.
