These plants are established for the reservoirs which possess well temperature between 100 and 170 °C. These plants use a process fluid which obtains heat from the geothermal fluid through heat exchangers in a closed loop. Depending upon the well‐matched boiling and condensation points of the geothermal fluid, different process fluids can be used such as ammonia/water mixtures used in Kalina cycles or hydrocarbons in organic Rankine cycles (https://iea‐etsap.org). The capacity of these plants varies between <1 MW and 50 MW (www.platts.com).
