ELECTRICITY GENERATION
 
There is no installed geothermal generating capacity as for December 2009.

Geothermal energy in Greece, despite of its relative high potential in the volcanic arc islands, does not have encountered a favorable support from government and local population. The small 2 MW unit at Milos, installed in 1987, has been decommissioned and dismantled. Several other projects are under evaluation (Nisiros, Tracia), both from PPC/Renewables and foreign investors, but the authorization process is still slowing the development. The most advanced is the 8 MW binary plant project in Lesvos, where few wells have already been drilling, identifying a shallow promising resource.

The first half of the present decade was characterized by a diversification of direct applications with new uses such as aquaculture, spirulina production, outdoor pool heating, water desalination and fruit and vegetable dehydration. However, in the past few years there has been a rapid expansion of geothermal heat pumps, with the increase in installed capacity since WGC2005 has been almost solely attributed to geothermal heat pumps.

There have been some reduction in use, mainly with the greenhouses and desalination plant on Kimolos Island being taken out of operation, and the 2.0 MWt project for heating and cooling several public buildings in Langadas (Thessaloniki) has been abandoned. The fate of a novel desalination project on Milos Island is still unclear, despite the completion of eight production and injection wells. Space heating is practiced only in two spa buildings, in a hotel in Milos, in several individual houses, and in a high school.

Approximately 21 ha of greenhouses are heated, mainly for vegetable and cut flower growing, with 27 greenhouse units in the country run by 21 operators. Some soil heating, especially for asparagus, has increased significantly and is now 17 ha. There are more than 60 thermal spas and bathing centers in operation. A tomato dehydration unit has been operating since 2001 producing more than 1,000 kg of dehydrated tomatoes per day. Geothermal water is used for frost protection for a number of aquaculture ponds during the winter. Approximately 350 geothermal heat pump applications are located in the country with about 65% being of the open loop configuration.

The figures for the various direct uses are:

1.5 MWt and 16.5 TJ/yr for individual space heating;
34.8 MWt and 340 TJ/yr for greenhouse heating;
9.0 MWt and 71.5 TJ/yr for fish farming;
0.3 MWt and 1.8 TJ/yr for agricultural drying,;
39.0 MWt and 238 TJ/yr for bathing and swimming;
50.0 MWt and 270 TJ/yr for geothermal heat pumps.

The total for the country is 134.6 MWt and 937.8 TJ/yr
