Arunachal Explores Geothermal Power for Remote Border Areas
Arunachal Pradesh is studying whether heat from underground can provide clean energy.
The state hopes this could help people in remote and border areas get reliable local power.
Minister Dasanglu Pul visited a geothermal project in Ladakh to learn about exploration and drilling.
Scientists have also studied hot-spring areas in Tawang district.
The state estimates that the Mago-Thingbu area may have potential for around 10 to 15 megawatts.
More studies are being planned to understand what the resource can do.
It might be used to make electricity, heat or cool places, and dry farm produce.
The studies have not yet established that a power facility will be built.
Arunachal Pradesh is assessing geothermal energy as a source of clean, reliable, locally generated power, especially for remote and border areas.
Science and Technology Minister Dasanglu Pul visited ONGC’s geothermal project in Puga Valley, Ladakh, with CESHS Director Tana Tage and departmental geologists.
The state estimates geothermal potential of around 10–15 MW in the Mago-Thingbu belt of Tawang district.
Investigations have included geological mapping and fieldwork at hot-spring locations, with samples collected at five Tawang sites for geochemical analysis.
CESHS and Oil India Limited have moved towards pre-feasibility studies; possible uses include electricity, heating, cooling and agricultural produce drying.
