NTPC signs PPA with Indian Army for solar-hydrogen microgrid in Ladakh

NTPC Limited has signed a Power Purchase Agreement (PPA) with the Indian Army for the sale of 200 kW round-the-clock renewable energy from a solar-hydrogen-based microgrid in Chushul, Ladakh. 

The 25-year agreement aims to enhance energy security in remote defence installations and reduce reliance on fuel transportation in challenging terrains.

The solar-hydrogen microgrid will replace existing diesel gensets, cutting carbon emissions by 1,500 tonnes annually. 

This initiative supports the decarbonisation and modernisation of defence infrastructure in border regions.

In October 2024, NTPC and the Indian Army partnered to establish the 200 kW microgrid at 4,400 meters altitude, providing stable power during extreme winters while improving energy self-sufficiency and reducing logistics challenges.
