A recent meeting highlighted the potential of geothermal energy exploitation in Phiotidis, a region north of Greece's capital of Athens. It pointed to the opportunities by geothermal for heating purposes for residences, baths and agricultural purposes.

The exploitation of geothermal energy in the area of Phthiotis (Fthiotida) was the main forum for discussion, which took place last week in Kamena Vourla by the Central Union of Municipalities (KEDE) in cooperation with the local municipalities. The point of reference for the event was the role of local government in the exploitation of geothermal fields. Scientifically substantiated proposals from geothermal scientists have demonstrated the potential of geothermal energy for the development of the area in many areas of economic activity.

As far as Phthiotis is concerned, there is a huge potential for exploitation, especially in the primary sector, to reduce production costs and increase productivity.

The data presented during the workshop showed that in many parts of the Sperchi basin there are surface thermal sources that indicate the existence of geothermal potential. According to IGME data, the areas that have the greatest geothermal interest in the Sperchius basin are the Lamia region of Stylida of the Hypath of Thermopylae, as well as Kamena Vourla.


The direct uses of geothermal energy in the wider region include a large field of business activity. Geothermal can be used for temperatures of 30 to 150 degrees Celsius for heating countries, hot baths, greenhouses, aquaculture, as well as for other agricultural and industrial processes.

From a specific study in the Damasht district, it is clear that in an area of 2.5 square kilometres the depth of the reservoir is from 50 meters to 350 meters, its temperature is 43.5 degrees Celsius and the estimated flow rate is 115 cubic meters per hour . It has been estimated that the cost of the thermal energy produced is EUR 13.5 per MWh, which is very low compared to conventional minerals.

Similar data and studies exist for other areas of ??Phthiotis with enormous potential. Business ideas and suggestions have begun to attract the attention of many stakeholders, but unfortunately they are hampered by existing legislation, which is a brake on growth.
