Arunachal studies geothermal energy potential in Himalayan terrain

Itanagar, Oct 3 (UNI) Arunachal Pradesh is examining the feasibility of tapping its geothermal resources for clean-energy generation, with particular focus on remote and border areas of the state.
State's Science and Technology Minister Dasanglu Pul, accompanied by Centre for Earth Sciences and Himalayan Studies (CESHS) Director Tana Tage and departmental geologists, visited the ONGC Geothermal Project at Puga Valley in Ladakh to gain first-hand insights into geothermal exploration, drilling and power generation in high-altitude Himalayan terrain.
The visit comes amid ongoing studies of geothermal prospects in Tawang district, particularly the Mago-Thingbu belt, where the state has estimated potential of around 10-15 MW.
Arunachal has been studying its geothermal resources for several years. CESHS, in collaboration with the Norwegian Geotechnical Institute and Iceland-based Geotropy, conducted field investigations and geological structural mapping of hot-spring sites in Mago, Thingbu and other areas in March 2024.
Further investigations and pre-feasibility studies involving surface and subsurface assessment have been undertaken by CESHS and Oil India Limited at Mago, Thingbu, Damteng and Tsechu. Field investigations have also been conducted at five geothermal sites in Tawang—Damteng, Grengkhar, Mago, Thingbu and Tsechu—with samples collected for geochemical analysis.
The studies are examining the potential use of geothermal resources for electricity generation as well as heating and cooling, agricultural produce drying and other locally suitable applications.
Pul said the experience gained from the Puga project would provide useful technical insights for Arunachal’s geothermal exploration efforts, particularly in remote and strategically located areas.
“Arunachal Pradesh is blessed with immense natural resources, and our endeavour is to harness this potential responsibly for a sustainable future,” Pul said.
The minister also appreciated ONGC and its execution partner SEROS for sharing their technical expertise and field experience with the Arunachal team.
