Geothermal energy creates less environmental pollution, is renewable and sustainable, avoids importing energy resources, benefits remote areas, adds to energy source diversity, creates less waste disposal and has a long life span.

Geothermal energy is produced by drilling a well into the ground where thermal activity is occuring. Once a well has been identified and a well head attached, the steam is separated from the water, the water is diverted through a turbine engine which turns a generator. Usually the water is injected back into the ground to resupply the geothermal source.

Garut Regency has the potential for geothermal energy is big enough that total is estimated to reach 1045 MW (Mwe). Geothermal energy sources can be used either directly or indirectly. As renewable energy, geothermal can be relied upon as a long-term supply. Adjacent to the power plant, this energy can be used for drying agricultural products, preservation of fisheries and tourism. Commercial utilization of the new direct to therapy and recreation, such as in Cipanas, while not directly for the use of power in the new developed area Darajat (350 MW). This of course makes the opportunities for development in the future.

Darajat geothermal project began in 1984 when signing Amoseas Join Operation Contract (Joc) with Pertamina and Energy Sales Contract (ESC) with PLN to build geothermal resources in Garut West Java. Until now, there are three units of Darajat geothermal energy, as follows:
