Primary Investigations
The Karkar site was selected for exploratory drilling on the basis of field investigations for the prospective sites of Jermaghbyur and Karkar, which were recognized as the most promising by local and international gethermal experts. In 2006, the World Bank Energy Invest PIU contracted "Ameria" CJSC, a professional advisory and insurance services company registered in Armenia, in the framework of the Global Environmantal Facility (GEF)/World Bank (WB) TF 053910 program to draft a detailed feasibility study for the construction of the Karkar GTPP. The study was executed in the framework of a governmental plan aimed at diversifying energy sources in Armenia and achieving greater independence from foreign imported energy sources. The results of the "Jermaghbyur geothermal power plant feasibility study" demonstrated the possiblility of constructing a Flash type geothermal power plant functioning on the basis of 6 production boreholes at 2.5-3km depth and 2 boreholes for return flow at 3km depth with installed capacity of 25MW. The necessary investments were estimated in the amount of 17.6 billion Armenian Drams (AMD), with specific costs per kilowatt of installed capacity at 1564 US Dollars (USD). At the time of the study the annual average electricity production was though to be 199.4 million kWh. That number has today grown up to 250 million kWh. The study demonstrated the stratigic importance and effectiveness of using geothermal energy in Armenia for the provision of heat supply and the generation of electric power. The field investigations at the prospective sites were supported under the Geofund 2: Geothermal Project financed by the Global Environmental Facility (GEF), which was completed in 2012. The field investigations works included: (a) field scouting; (b) magneto-telluric sounding (MT) study; (c) independent interpretation of the results of the MT study; (d) three-dimensional (3D) MT study, and (e) independent interpretation of the results of the 3D MT study.
