Country Update: The country has a high potential of geothermal resources, some of which has been in use since ancient times. The major areas of utilization are balneology resorts, local heating systems, the processing industry and greenhouses. No estimates were made for installed capacity and annual utilization, thus in correspondence with the authors, the following estimates are made:

Currently, the water low in minerals (45 to 50oC) is used in the central area of the capital by the Tbilisi Balneological Health Resort and the hygienic bath houses. The high temperature water (57 to 74oC) in the Lisi and Sburtalo area of Tbilisi is used for hot-water supply and for the heating of residences and offices. In addition, there is farming and other complexes under construction at Lisi Lake. Future plans are to install a central distribution system in Tbilisi so as to eventually supply all of the city with geothermal heated water for heating.

The various applications are:

12.57 MWt and 345.09 TJ/yr for individual space heating;
7.74 MWt and 224.79 TJ/yr for district heating;
2.20 MWt and 59.36 TJ/yr for greenhouse heating;
2.00 MWt and 30.00 TJ/yr for bathing and swimming.

The total is 24.51 MWt and 659.24 TJ/yr.
