Developers that won SIGHT production incentives and supply contracts - they own the electrolyser plants and sell green hydrogen or ammonia.
A producer combines renewable power, electrolysers and (for ammonia) a synthesis loop at one site, then sells hydrogen by pipeline or ammonia by ship. SIGHT pays a bid incentive per kg for the first three years of output; SECI and refiners sign 10- to 25-year supply contracts.
Production awards first totalled 8.62 lakh tonnes a year across two tranches (4.12 lakh tonnes in Jan 2024 and 4.5 lakh tonnes in Mar 2025, the latter with up to ₹2,239 Cr of incentives); MNRE's Aug 2026 figure is ~7.56 lakh tonnes a year to 16 companies. Winners include Reliance, L&T, Waaree, AM Green, ACME, Greenko, JSW Neo, CESC, Sembcorp's Green Infra and others.
The largest pool in the chain by capex - AM Green's Kakinada complex alone plans 7.5 GW of renewables and ~1.95 GW of electrolysers. Returns depend on contracted prices, capacity utilisation of electrolysers and the cost of firm renewable power.
