Union Consumer Affairs and New and Renewable Energy Minister Pralhad Joshi on Sunday, 19 July 2026 announced that India has commissioned its first-ever geothermal wells at Puga Valley, Ladakh, marking what he called 'a landmark milestone in India's clean energy journey.' The wells, drilled 1,000 metres deep at an altitude of over 14,000 feet, are intended to power the country's first 1 MW geothermal power project.

Context

Puga Valley, located in eastern Ladakh, has been recognised as one of India's most promising geothermal sites since surveys began in the 1970s. The valley's natural hot springs and subsurface heat resources drew early attention from the Geological Survey of India and ONGC, though commercial exploitation remained elusive for decades due to technical and logistical challenges posed by the region's extreme terrain and altitude.

Ladakh, a Union Territory carved out in 2019, faces persistent energy access difficulties owing to its remoteness and harsh winters. Diesel generators have historically served as the primary backup power source, making the shift to indigenous geothermal energy particularly significant for local communities.

Policy Backdrop

India's geothermal push is part of a broader diversification of its renewable energy portfolio following the country's pledge at COP26 in 2021 to achieve net-zero emissions by 2070. While solar and wind have dominated India's clean energy expansion, both are intermittent sources. Geothermal energy, by contrast, offers round-the-clock baseload power unaffected by weather or daylight cycles, making it a valuable complement to variable renewables.

The Ministry of New and Renewable Energy, which Joshi heads, has been tasked with broadening India's clean energy mix to include less conventional sources. The Puga Valley project represents the ministry's first concrete step toward establishing geothermal as a viable component of that mix. Joshi stated the breakthrough 'strengthens India's renewable energy ambitions and supports the vision of a Net Zero and carbon-neutral future.'

Stakeholders and Impact

For Ladakh's residents, a functional geothermal plant would mean more reliable, cleaner electricity — reducing dependence on costly diesel imports that must traverse difficult mountain roads. The extreme cold of Ladakhi winters makes uninterrupted power supply a necessity rather than a convenience, and geothermal heat can also be harnessed directly for space heating.

Renewable energy developers and the broader clean-tech sector are watching the project closely. A successful 1 MW demonstration could open the door to larger geothermal capacity bids under future policy rounds, while also providing a replicable model for other high-altitude geothermal sites identified across the Himalayan arc. The project also carries strategic significance, as energy self-sufficiency in Ladakh supports India's broader infrastructure development goals in a sensitive border region.

What's Next

The commissioning of the wells is a preparatory step; the 1 MW plant itself must still be built, tested, and connected to the local grid. Observers will track the project's construction timeline and whether the Ministry of New and Renewable Energy announces dedicated geothermal policy guidelines or competitive bidding rounds to scale capacity beyond this pilot. India's experience at Puga Valley could inform geothermal exploration at other identified sites, potentially adding a new, weather-independent pillar to the country's renewable energy architecture ahead of its 2070 net-zero target.
