Renewable energy in India is growing leaps and bound under government ambitious plan of enhancing renewable capacity to 175 GW by 2022. While solar and wind continue to drive this initiative, new and upcoming technologies such as geothermal, ocean and tidal are being promoted to enhance renewable share to 25 % in energy mix, from current 7 %.
Geothermal Potential in India
India is blessed with good potential for geothermal energy. India is considered to have Low (<100 Degree C) to medium (100- 200 Degree C) enthalpy regions. Surveys done by Geological Survey of India have earmarked 340 hot springs within temperature range of 34 Degree C to 98 Degree C. The major potential areas for geothermal energy (both thermal and power) in India are identified as under:
- Northern India:
Puga, District: Leh, State of Jammu and Kashmir
(Temperature range is between 30 degree C to 84 degree C, which is boiling point at Puga and discharge is around 300 liters/minute).
District Manikaran, State of Himachal Pradesh & Chhumathang, State of Jammu & Kashmir.
- West India:
Tattapani, State of Chattisgarh (highest potential in country)
State of Gujarat (Cambey Graben), Maharasthra (district: Unai and Jalgaon).
Tattapani region in India has the highest potential for geothermal in India as Thermal manifestation is very intense in an area of 0.05 sq.km with several hot spots, hot water pools and marshy land. The surface manifestations show occurrence of white to dirty white deposits identified as silica and moderate to low sag activity.
Geothermal potential in Kutch region in Gujarat (west India) is being explored, and geological faults and crustal structure have been mapped in Kutch by Institute of Seismological Research (ISR).
- East India:
State of West Bengal (district: Bakreshwar)
For More details on Geothermal Potential.
India does not have any installed geothermal. However India is in process of setting up first geothermal project in West India (State of Chhattisgarh) by National Thermal Power Corporation (Public Utility in Power Generation). Non availability of machinery and equipment for deep drilling has been holding up commercialization of geothermal energy.
Mission and Vision in Geothermal for India
Indian government is developing roadmap to achieve following targets in geothermal energy
|Target Year||Geothermal (Energy) MW||Geothermal (Power) MW|
The Indian Government has identified following targets wherein geothermal energy can be used
- Promote geothermal heating solution by Retrofitting of HVAC systems with Geo Exchange based system.
- Ground source heat pumps (16-29 degree temp) to provide heating and cooling solution for homes, commercial and Industrial purpose
- Electricity generation
- Machinery and equipment for deep drilling
- Oil and Natural Gas Corporation, India is looking for technology providers, manufacturers, strategy partners for geothermal projects in their exhausted oil wells
Incentives by Government to Promote Geothermal
The Indian Government is finalizing National Policy on Geo-Thermal Energy and Guidelines for development of Geo-Thermal Energy in India and the draft versions have been released. The Policy promotes Geothermal through a series of incentives and waivers to geothermal developers both for electric generation and heat energy.
Few Proposed Incentives are:
- 30 % subsidy on capital cost for the installation of geothermal projects.
- For Research, Development and Deployment and Demonstration projects, 50 % subsidy has been proposed.
- Involvement of foreign companies to be encouraged for exploration and development (provided foreign collaboration is ted up with technology transfer) as 100 % FDI already allowed in renewable energy sector.
- 80 % depreciation allowed for heat pumps in 1st year itself.
- Import, excise and tax benefits on equipment and machinery to be allowed.
- RDD & D opportunities in use of geothermal purpose of cooling, heating, drying, greenhouse cultivation, industrial processes, cold storage, mushroom farming, fish farming etc., Retrofitting HVAC system by geothermal based system.
- Suitable demonstrations site to be granted by Government for geothermal projects (both thermal and electric).
- Land at cheaper rates (same rates as provided to government bodies).
Ministry of New and Renewable Energy, India (MNRE) is keen on exploring projects in new and innovative technology areas of renewable energy such as geothermal, ocean thermal energy and tidal and wave energy. Ministry shall facilitate projects in geothermal energy using technologies which are sustainable, scale able and make economic viability.
Innovation Norway India shall be pleased to assist Norwegian companies in geothermal space and help in market entry in India.
