At present, most of the operational geothermal power plants are flash power plants. These plants work similar to dry steam plants; the only difference is steam production step. Steam is produced from flashing, a separation process for the two‐phase fluid, and then passed into the turbine. Flash plants are of three types, single, double and triple depending upon the capacity of the plant. In a single flash plant, condensate resulting from the turbine is re‐injected into the well while in a double‐flash plant, the condensate is directed for further separation at lower pressure to generate more steam. In a triple‐flash plant, the process of flashing is repeated one more time. Flash power plants are suitable for those reservoirs which possess well temperature >180 °C (IRENA 2017). Triple‐flash plants have the maximum power capacity (60–150 MW) followed by double (2–110 MW) and then single having the least capacity between 0.2–80 MW (www.platts.com).
