Abstract

Eastern part of peninsular India has exposed Precambrian metasediments, granitic gneissic rocks, basic and ultrabasic intrusives. More than 30 thermal springs issuing through these rocks have been located in the states of Bihar, Jharkhand, and West Bengal. Based on chemical geothermometry of these thermal waters, the reservoir temperatures are estimated to be in the range of 100–195 °C. The area has high heat producing granites with the heat flow values ranging from 59.8 to 119.5 mW/m2. The area is suitable for hosting wet as well as a dry geothermal system. Using Organic Rankin Cycle, a minimum potential of Eastern Peninsular India is estimated to be of 2566 MWe capacity. The exploitation of these geothermal systems in the area can help reduce greenhouse gases. Approximately 6 × 105 tons of CO2 emissions per year can be reduced as well as carbon equivalent revenue of 106 million USD per year can be generated with the installation of geothermal power plants. Furthermore, geothermal fields in the region can also be utilized for fish farming, cold storage, greenhouses, etc.
