Turkey - Electricity Generation

A significant development was achieved in Turkey in geothermal electricity production and direct uses (district, greenhouse heating and thermal tourism) during last five years, also due to the new Geothermal Law, its regulations and the feed in tariff. About 225 geothermal fields have been discovered in Turkey, and today electricity production has reached almost 400 MWe, with more than 350 MWe of new plants. A liquid carbon dioxide and dry ice production factory is integrated to the Kizildere geothermal power plant. The existing plants are in the following areas: Çanakkale-Tuzla 7 MWe, Aydin-Hidirbeyli 68 MWe, Aydin-Salavath 35 MWe, Aydin-Germencik 98 MWe, Aydin-Gümüsköy 7 MWe, Denizli-Kizildere 107 MWe, Aydin-Pamukören 48 MWe, Manisa-Alasheir 24 MWe, Denizli-Gerali 3 MWe) (Mertoglu, et al., 2015).

Development since WGC2010: in impressive amount of new units, for a total of about 350 MWe.

Installed capacity 397 MWe                   
Geothermal Electricity 3,127 GWh/y

Installed geothermal generating capacity (December 2009) in MW 


Since 2005 several construction activities have been carried out. Three new binary units of about 8 MW each have been realized, two for exploiting medium enthalpy reservoir (Dora - MB group, in Aydin-Salavatli area, at 167°C and Tuzla - Dardanel Energy, at Canakkale, still under construction) and one on the downstream of the separated brine (140°C) from the Kizildere plant, before its use for district heating, operated by Bereket .

The old plant of Kizildere, after the privatization, now owned by Zorlu group, has been refurbished and it is operating at full capacity (15 MW as the generator capacity, while the turbine is 20 MW), and a new 60 MW plant is under construction. The reservoir temperature is about 240°C. The plant is producing also 120,000 ton/year of pure CO2 for the food industry. 
A new 47 MW double flash unit has been commissioned in 2009 at Germencik, by the Gurmis group, with the option of a further 47 MW as potential expansion. It is one of the biggest plant in Europe, following only the Italian standard 60 MW units. The brine temperature is 230°C.

Several additional areas have been allocated to private companies for further surface and deep exploration. Since 2005 an increase of 60 MW, corresponding to an impressive 300%, has been achieved. The target for about 200 MW in year 2015 is solid and achievable.
