Turkey is located on the Alpine-Himalayan orogenic belt, which have high geothermal
potential. The first geothermal researches and investigations in Turkey started by
MTA in 1960’s. MTA discovered 170 geothermal fields where 95% of them are low-medium
enthalpy fields and suitable mostly for direct-use applications. In addition about
1,500 hot and
mineralized natural springs and wells exist in Turkey. 170 geothermal fields which
can be useful at the economic scale and about 1,500 hot and mineral water resources
which have the temperatures ranged from 20-242°C (spring discharge and reservoir
With the existing springs (600MWt) and geothermal wells (2,693MWt), the proven
geothermal capacity calculated by MTA is 3,293MWt (discharge temperature is assumed
to be 35°C). The geothermal potential, on the other hand, is estimated as 31,500MWt.
The installed heat capacity is 1,077MWt for direct-use and 20.4MWe for power
production in Turkey with total production of 104.6GWh/yr. A liquid carbon dioxide
and dry ice production factory is integrated to the Kizildere power plant with a
40,000 tons/year capacity.
