India's wind power sector is driven by a strong indigenous industry with a manufacturing capacity of 18,000 MW annually. As of January 31, 2025, the country ranks fourth globally in installed wind capacity, reaching 48.37 GW. According to MNRE, India's wind potential is estimated at 695.50 GW at 120 meters and 1,163.9 GW at 150 meters (source:MNRE). SECI plays a key role in harnessing this potential by implementing large-scale wind projects nationwide. It issues tenders to select renewable energy developers through a competitive tariff-based e-bidding process. SECI then signs 25-year Power Purchase Agreements (PPAs) with developers and back-to-back Power Sale Agreements (PSAs) with DISCOMs.This approach has optimized wind power tariffs, fostering industry competition and enabling cost-effective wind energy procurement across states, thereby promoting large-scale inter-state power transfer.
