In a landmark development under the National Green Hydrogen Mission, the first-ever auction conducted by Solar Energy Corporation of India (SECI) for the procurement of Green Ammonia under the SIGHT Scheme (Mode-2A) has achieved a record low price discovery of INR 55.75/kg. ACME Cleantech Solutions emerged as the winning bidder.
This auction covers the supply of 75,000 metric tonnes per annum of Green Ammonia to Paradeep Phosphates Ltd., Odisha. It is the first in a planned series of 13 auctions over the coming month, under a tender aggregating a cumulative procurement capacity of 7.24 lakh MT/year, shared SECI in a statement.
It further added that the discovered price translates to approximately USD 641/MT, a substantial drop from the previously discovered price of USD 1,153/MT in the H2Global auction. With Grey Ammonia prices reaching USD 515/MT (as of March 2025), this 10-year fixed-price bid provides strong economic rationale for offtakers to initiate their clean energy transition journey.
“This price discovery marks a watershed moment in India's Green Hydrogen journey and reinforces the country’s vision of becoming a global hub for Green Hydrogen production. The auction witnessed intense competition, reflecting the strong investor and developer confidence in India’s green energy transition framework,” stated SECI.
It further added that the cost-discovery-based model deployed here directly addresses one of the sector’s biggest barriers – offtake assurance for Green Hydrogen derivatives. “With robust payment security mechanisms in place, the scheme unlocks confidence across the value chain and enables large-scale adoption of Green Ammonia and other derivatives,” it said.
