| Abstract |
In the meantime between the W.G.C. of 2005 and present day, some developments have been done in the whole sector of geothermal energy in Greece. New geothermal fields have been located, studied and reported. In 2003 the legislation governing the exploration and exploitation of geothermal energy has been changed with a new law, followed by the signing of a number of Ministerial Decisions for its application, finalized by the 2006. The country?s geothermal potential has been increased by the location of new fields over the whole country. The new located fields are found in the Aegean islands (Chios Island), the Western Greece (Sykies Arta and Antirio fields), the Macedonia region (Kavala Akropotamos and Volvi fields), the Central Greece (Nikaia, Damasta, Aedipsos and Yaltra fields). The studied fields are of low enthalpy with the temperatures ranging between 35 and 84oC. The main advance in the new legislation was the special provision for licensing the use of Ground Source Heat Pumps. Up to now there was not any provision for it. This sector of geothermal heat/cooling is the most fast developing in the country during the last two years. Electricity production has not seen any progress, except the actual deep drilling of Public Power Corporation (P.P.C.) in NW part of Lesvos Island for high enthalpy field. Direct uses have not undergone any development mainly due to the new legislation which has been finalized at 2005, and some applications for district heating are still pending. GSHP have seen a rapid development due to the change of legislation |
