Oil and Natural Gas Corporation (ONGC) will conduct India’s first geothermal field development project to be carried out in Ladakh Puga region.

On February 6th, the ONGC Energy Center (OEC) signed a Memorandum of Understanding (MoU) with Ladakh and the Ladakh Autonomous Hill Development Council, Leh.


This project will be implemented in three phases.

The Phase-1 involves exploratory-cum-production drilling of wells up to 500 metres depth and setting up of a Pilot Plant of up to 1 MW power capacity.

Phase-II would involve deeper and lateral exploration of geothermal reservoir by drilling of optimal number of wells and setting up of a higher capacity Demo Plant and preparing a Detailed Project Report.

Phase-III would involve commercial development of the geothermal plant, the energy company said.

The MoU was signed in Ladakh on 6 February 2021: ONGC

Ladakh Lt. Governor R K Mathur reckons the area can support a power generation capacity of 250 MW.

Puga and Chumathang area in Ladakh are deemed as the most promising geothermal fields in India. These areas were discovered in 1970s and initial exploratory efforts were made in the 1980s by Geological Survey of India (GSI).

Geothermal energy is a renewable source of energy stored beneath the surface of the Earth in the form of heat. This energy is clean, sustainable, carbon free, continuous, uninterrupted and environment-friendly
