VK Saxena, the Lieutenant Governor of Ladakh, has commissioned India's first and deepest two 1,000-metre geothermal wells at Puga Valley, Ladakh. These wells, executed by the Oil and Natural Gas Corporation Ltd (ONGC) Energy Centre, are critical for the 1 Megawatt (MW) Pilot Geothermal Power Plant.
This project is India's first demonstration-scale geothermal power project situated at an altitude of over 14,000 feet. It is to be noted that the wells reached a maximum temperature of 135°C at a depth of 400m.
