The Solar Energy Corporation of India (SECI) has successfully concluded the auction for 1,200 MW of Inter-State Transmission System (ISTS)-connected wind power projects under Tranche XlX, marking an important development for India’s wind energy sector. The auction highlights growing interest from developers and rising confidence in the country’s renewable energy market.
The bidding was conducted through a tariff-based competitive bidding process, with discovered tariffs ranging between ₹3.67 per kWh and ₹3.69 per kWh. A total of seven companies emerged as winners, reflecting healthy competition in the tender.
KP Energy secured 100 MW at the lowest tariff of ₹3.67 per kWh. GANEKO THREE ENERGY (Zelestra), Waaree Forever Energies, and Opera Energy won capacities at a tariff of ₹3.68 per kWh. Vena Energy Aura and Refex Holding secured projects at ₹3.69 per kWh. Among all bidders, Waaree Forever Energies emerged as the largest winner, securing 300 MW at ₹3.68 per kWh. Opera Energy won 50 MW at the same tariff.
The Tranche XIX tender was initially issued by SECI in October 2025 for 600 MW of wind power capacity. Due to strong market interest, the capacity was increased to 1,200 MW in December 2025. The projects will be connected to the ISTS network, allowing power to be supplied across state boundaries and supporting grid-level renewable energy integration.
SECI, a Government of India enterprise under the Ministry of New and Renewable Energy, plays a key role in implementing India’s clean energy targets. The successful completion of this auction underlines SECI’s efforts to accelerate wind power deployment through transparent and competitive bidding mechanisms.
With competitive tariffs and strong participation from developers, the Tranche XIX auction is expected to support India’s renewable energy goals, enhance energy security, and contribute to the country’s transition toward a low-carbon power system.
