India Commissions First Geothermal Wells in Puga Valley, Ladakh

India has commissioned its first and deepest geothermal wells at Puga Valley in Ladakh, marking a significant step in the country’s clean-energy transition and Ladakh’s goal of becoming carbon-neutral. This development is crucial for UPSC aspirants, especially for GS Paper 3, which covers energy and environmental issues. Last Updated: 22-07-2026

Key Facts About the Project

• Location and Depth: Both wells have been drilled to a depth of 1,000 metres at an altitude of more than 14,000 feet in Puga Valley, a promising geothermal energy location in India.
• Power-Generation Target: The wells will support the proposed 1 MW pilot geothermal power plant, marking India’s first demonstration-scale geothermal power project.
• Working: The project will harness heat naturally stored beneath the Earth’s surface to generate reliable, round-the-clock renewable electricity, unlike weather-dependent solar and wind power.
• Temperature: A maximum temperature of 135°C has been recorded at a depth of 400 metres, with further testing underway to assess higher temperatures and the reservoir’s commercial potential.
• Executing Agency: The project is being implemented by the ONGC Energy Centre in collaboration with the Ladakh Administration and the Ladakh Autonomous Hill Development Council, Leh.

India's Clean Energy Transition

The commissioning of geothermal wells in Puga Valley is a significant milestone in India's clean energy transition, aligning with the nation's strategic goal of achieving carbon neutrality. This project not only enhances India's renewable energy portfolio but also positions the country as a leader in sustainable energy solutions. With the global geothermal power-generation capacity reaching 15.4 GW by the end of 2024, India is poised to tap into its estimated 10,600 MW geothermal potential, contributing to its economic and environmental objectives.
