Sanko Enerji has set a new industry record by discovering Türkiye’s hottest geothermal resource to enter production, reaching a temperature of 308°C.
Sanko Enerji, a subsidiary of Sanko Holding, has discovered Türkiye’s hottest geothermal resource to date that has reached the production stage. With a temperature reaching 308°C, this new resource once again highlights the country’s significant geothermal energy potential.
In a statement made by the Geothermal Power Plant Investors Association (JESDER), they said: “After a determined and challenging exploration process, we proudly learned that Türkiye’s hottest producing geothermal well, reaching a temperature of 308°C, has been successfully discovered.” JESDER emphasized that this important development once again underscores the strategic role of geothermal energy among renewable energy sources.
In Türkiye, geothermal resources suitable for electricity generation typically range in temperature from 103°C to 295°C. Lower-temperature resources are generally used for thermal tourism and heating purposes. On a global scale, geothermal resources considered suitable for investment in energy production range from 140°C to 370°C.
While Sanko Enerji’s discovery stands out as the hottest geothermal resource in Türkiye to have reached the production stage, previous exploration activities in the country had also recorded high temperatures. In this context, a well drilled by 3S Kale Enerji within the Nigde-Aksaray license area reached a depth of 3,957 meters, with a bottom-hole temperature measured at 341°C. Right before this, the company had drilled into a 295 °C resource, also in the same field.
