Geothermal Energy in Greece

Geothermal localities in Greece

Greece has a great geothermal potential. This potential has been confirmed and verified by the discovery and exploration of new geothermal fields during the past five years (1995-1999). During this period the geothermal research and applications were mainly related to low enthalpy fields.
The areas of research include Northern Greece (Thrace, Macedonia), NW Greece (Epirus), Chios and Lesvos islands (Aegean Sea). In Thrace, near the village Aristino, a new geothermal field was discovered, the temperature of which approaches 92oC. At the area of Sappes (Thrace), some very promising fields were identified through a series of exploration and production wells. Very interesting fields were also discovered in Central Macedonia (Sani and Neo Ryssio district). In NW Greece (Sykies, near Arta, Epirus) the exploration wells brought to light another geothermal field whose temperature is 48ºC. Finally, in Chios Island the recently discovered geothermal field gave temperatures up to 90ºC.

As is already known (Fytikas 1988; Fytikas et al, 1995 and 1999; Chiotis et al, 1990) there are two high enthalpy geothermal fields in Greece, namely Milos and Nisyros, where seven deep wells identified temperatures of 320ºC and 350ºC respectively. In addition, low enthalpy (T<100ºC) geothermal fields abound in Greece, mainly in the east and north parts of the country, as well as in many Aegean islands. Present data yield a low enthalpy potential exceeding 400 MWt proven and 800 MWt probable.

In 1995 geothermal applications were limited to spas and greenhouses. Greece is rich in geothermal waters, since the greatest part of the country is situated on a geodynamically very active area.
Even in Western Greece, which is the least favorable territory in terms of geothermics, and particularly in the areas of Antirrio and Sykies, promising data have been acquired.
