Where were India's first two geothermal wells commissioned?
- A.Tattapani, Chhattisgarh
- B.Puga Valley, Ladakh
- C.Manikaran, Himachal Pradesh
- D.Ankleshwar, Gujarat
Correct answer
Explanation
The correct answer is Puga Valley in Ladakh. The backgrounder records that the ONGC Energy Centre commissioned the country's first two geothermal wells there in July 2026. The valley lies at over 14,000 feet above sea level, is known for its hot springs and underground heat reserves, and is among India's most promising geothermal sites. Each well goes down about 1,000 metres, and together they pave the way for India's first 1 megawatt demonstration geothermal power project. Option A, Tattapani, and option C, Manikaran, are genuine and well known Indian geothermal fields, which makes them the strongest distractors in any question of this kind, but neither is the site of these first wells. Option D, Ankleshwar in Gujarat, does appear in the same backgrounder, but in a different role: it hosts a pilot project evaluating electricity generation by retrofitting unproductive oil and gas wells. Attach the words first two wells firmly to Puga Valley.
