The exploration right of the Kawu Geothermal Field covers an area of approximately 105 square kilometres. The surface water temperature in the boiling spring area ranges from approximately 62°C to 86°C and there are more than 100 springs surrounding by rich sulphur, salt frost and large travertine.
Based on the geological structure and geochemistry preliminary analysis, it is estimated that the geothermal pay zone of the Kawu Geothermal Field might be at depth from 1,500 to 2,000 metres with possible temperature ranges from approximately 170°C to 240°C. The field has the characteristics of shallow burial depth of geothermal energy resource and abundant groundwater, which are supportive for the geothermal fluids collection, and is one of the developing regions with the best geothermal energy resource potential in the Tibet Autonomous Region, the PRC.
According to the "Validation Survey Report of the Proposed New Geothermal Energy Exploration Right in Kawu, Sa'gya County, the Tibet Autonomous Region" dated 10 September 2018 prepared by the Bureau of Geologic Exploration and Mineral Development of the Tibet Autonomous Region, the PRC, the Kawu Geothermal Field has an estimated power generation potential of up to approximately 80 megawatts, representing a larger scale potential geothermal energy development project in the PRC.
