Activity in the field of geothermal energy in Turkey started in 1961 with an inventory of Turkey's hot springs by the Mineral Research and Exploration General Directorate (MTA). Subsequent investigation revealed the great potential of geothermal energy. To enable full utilization of this potential, Turkey was divided into six geothermal regions which are being individually and systematically developed. In 1963, the first geothermal exploration drilling took place in the Agamemnun (Balcova) field which is west of Izmir. At the depth of 40 meters (130 feet) the well yielded a mixture of hot water and steam at the temperature of 124°C (255°F). The first geothermal field which was utilized for electricity production is in Denizli-Kizildere. Exploration of this field started in 1968. A power plant which has a generation capacity of 20 MWe is now in operation. Another well known geothermal field that was explored in 1982 is Aydin-Germencik field with a temperature of 231°C (448°F). The names of other well known geothermal fields are lzmir-Seferihisar, Afyon-Omer-Gecek, Canakkalellala, lzmir-Dikili-Bergama, Kutahya-Sima y, and Ankara-Kizilcahamam
