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.

印度东部半岛地热潜力评估的初步调查

印度半岛东部已暴露出前寒武纪沉积物，花岗岩片麻岩岩，基本和超基性侵入岩。在比哈尔邦，贾坎德邦和西孟加拉邦分布着30多个通过这些岩石发出的温泉。根据这些热水的化学地热法，储层温度估计在100–195°C的范围内。该地区有大量产热花岗岩，其热流量范围为59.8至119.5 mW / m ²。该区域适合于容纳湿地和干地热系统。使用有机兰金循环，印度东部半岛的最小潜力估计为2566 MWe。在该地区开发这些地热系统可以帮助减少温室气体。约6×10 ⁵通过安装地热发电厂，每年可以减少₂ 万吨的CO ₂排放量，每年可以产生1.06亿美元的碳当量收入。此外，该地区的地热田还可以用于养鱼，冷藏，温室等。
