| Abstract | 250 geothermal boreholes were drilled with summarized heat capacity to 427 MW(t). On most scales geothermal heat supply was developed in Kamchatka, Krasnodar region and Dagestan. Heat capacity of geothermal heat supply of these regions is 122 MW(t), 77 MW(t), 71 MW(t) respectively. Heat supply [110 MW(t)] from geothermal resource use is in second place after green-house heating [160 MW(t)]. In Russia, the Krasnodar region is leading by volume of geothermal heat supply (18 deposits, 86 boreholes, summarized potential heat capacity to 250 MW(t). Business plans geothermal heat supply for five cities, including Labinsk [100 MW(t), 4 MW(e)]. Construction of demonstration geothermal project in settlement Rozoviy (5 MWt) is being conducted. Heat carrier from two boreholes with temperature 100ºC goes to a central heat point, where its temperature potential is extracted down to 30ºC cascaded and goes to ponds (mineralization 2g/l). Reinjection of the used geothermal heat carrier is provided for the second stage. Construction of two solar stations with capacity 30 m3/day with pump drive from photoelectrical modules is provided to decrease the consumption of geothermal water in summer time. For bad weather there was provided installation of heat pumps of “air-water” heating water after solar stations. |
