Abstract: Greece has a lot of geothermal energy fields. Due to legal inefficiencies, the exploitation of this renewable energy source remains at very low levels. In this work, the operation of a cogeneration (hot water and electricity) geothermal plant that could be built in Eratino, Greece, is analysed. The research on the development of a low enthalpy geothermal field is investigated as a very essential investment. The building of small geothermal power plants to supply mini-grid power in remote locations with geothermal resources, has proved to be very important. Exergy analysis is used for the evaluation of the efficiency of the exploitable unit. The environmental impacts of the geothermal plant are also examined.

Keywords: environmental impacts; exergy; exergy efficiency; geothermal energy; Greece; cogeneration; co-generation.
