Title: Research and development of geothermal resources in Greece: present status and future prospects

Conference · · Geothermics; (United States)
OSTI ID:6138114

Geothermal energy in Greece is attracting attention as a potentially important contributor to the national energy sources. The geological structure of this country is such that favourable conditions exist for geothermal resources. Hydrothermal systems have already been identified on the islands o Milos and Nisyros (Aegean Sea). Results of preliminary production tests in the five existing geothermal wells on Milos can guarantee the operation of geothermal electric condensing units to a total capacity of about 24 MW. The first exploratory wildcat well, drilled on Nisyros (caldera area) to a depth of 1816 m, confirmed the existence of a very high temperature deep reservoir. Integrated interpretation of prospectings carried out in the areas of second priority order (Lesbos, Loutraki-Sousaki, Platystomon, Aedipsos, Poros, etc.) is now under way, aimed atdiscovering other economically exploitable geothermal fields. The northern part of Greece, where the active tectonic of Macedonia (Strymon Valley and Langadas-Volvi zone) has favoured the existence of medium to low enthalpy geothermal systems, which can be exploited for direct heat applications. By the end of 1984 the first Greek geothermal power-plant of 1.5-4 MW will be installed on Milos, and by the end of 1986 a 4 - 5 MW pilot plant could be installed on Nisyros, providing the second well proves productive. The maximum geothermal electric potential of Milos has been estimated at 100-200 MW. Therefore the electric energy produced could be transmitted economically from Milos to a significant number of islands in the Aegean Sea and to the mainland by means of a system of a.c. submarine cables by 1992. The availability of local geothermal sources on the islands of the Aegean Sea could thus represent appreciable savings in imported oil.
