NTPC has signed a power purchase agreement with the Indian Army to supply renewable power from its solar-hydrogen based microgrid project at Chushul, Ladakh. The project, offering 200 kW of power round-the-clock, intends to replace the Army's diesel gensets, thereby eliminating the need for fossil fuel logistics and reducing CO2 emissions by 1500 tons annually. This initiative is considered the world's most unique hydrogen-based off-grid microgrid project, situated at an altitude of 4400m with temperatures dropping to -30°C in winters. NTPC believes that once operational, this project will mark a significant shift towards decarbonisation and modernization in the defense sector at the Himalayan border regions. The 25-year agreement highlights a major advancement in promoting energy security and sustainability in the challenging terrains of Ladakh.
