GEOTHERMAL ENERGY POTENTIAL OF TURKEY AND RESEARCH STUDIES

Geothermal energy is clean, cheap and environmentally friendly, which is our domestic energy source. Turkey is located on an active tectonic zone as geological and geographical location,  and for this reason our country is rich in terms of geothermal energy resources. Our country have approximately 1000 geothermal springs that located all over the country that have various of temperatures.

The geothermal capacity of our country is very high. 78% of these geothermal fields are situated in Western Anatolia, 9 in Central Anatolia, 7% in the Marmara Region, 5% in Eastern Anatolia and 1% in the other regions. 90% of our geothermal resources are low and medium enthalpy Geothermal areas which are suitable for direct applications (heating, thermal tourism, industrial usage, etc.), while 10% are suitable for indirect applications (generation of electricity).

Geothermal sources have widespread uses in Turkey. Today geothermal energy is used for electricity production, heating (greenhouse and residences), thermal and health tourism, industrial usages, fish farming, for drying purposes and etc.. First geothermal electricity generation held in Kızıldere geothermal field by MTA in 1975 and was initiated by Kızıldere power plant with 0.5 MWe power.

The installed capacity of geothermal energy as of year 2018 was 14.9 GWe. Top five countries in this area are the USA, Philippines, Indonesia, Turkey and New Zealand. Total direct use of geothermal energy in the World with same reference is higher than 70.000 MWt as of year 2018. Top 5 countries in direct usage applications are USA, China, Sweden, Belarus and Norway.

Geothermal resource explorations had been started at 1962 by MTA and brought up to date with  287.5 ° C temperature with scientific researches that conducted also by MTA.

Unfortunately, because of some political reasons, geothermal activities come to a halt from 1990 to 2004 years. In order to develop existing resources and to search for new resources/fields, which is our ministry projections also, MTA’s geothermal budget increased about ten times for geothermal energy explorations and drillings reached from 2.000 meters to 28.000 meters.

In 2005, with the support of our ministry, the development of existing geothermal resources initiated and began to search for new potential areas. Due for this mobilization, our usable geothermal heat capacity increased eith MTA’s drilling activities, 173 discovered geothermal fields reached to 239 fields which 10 of them are suitable for electricity production. So far, total of 634 drillings with total of 412.500 meters of depth performed by MTA and approximately 5000 MWt of heat energy (including natural springs) obtained from these wells.

In 2008, after the Geothermal Resources and Natural Mineralized Waters Law come into force, private sector began to introduce development and investment of geothermal projects also. With this development, the country's total geothermal heat capacity (visible amount of heat) reached to 35.500 MWt.

From the year 2008 till today, totally 101 geothermal fields which is 16 of them are suitable for electricity generation, has been tendered to private sector. This geothermal development provides the highest contribution to the economy and also employment.
