Torrent Green Energy (Torrent Power) has won Solar Energy Corporation of India’s (SECI) auction to set up 600 MW interstate transmission system (ISTS)-connected wind power projects under Tranche XVIII.

Torrent has won 300 MW at a tariff of ₹3.97 (~$0.046)/kWh.

The tender was floated in March 2025 for 400 MW, which was later increased to 600 MW.

Out of the total 600 MW capacity that was tendered, only 300 MW was awarded because the total eligible bids received were significantly lower than the floated capacity. Per the tender clause, when the total techno-commercially qualified capacity is less than or equal to 600 MW, SECI can award only up to 80% of that capacity.

If the remaining capacity falls below the mandated minimum of 50 MW allotment requirement, it will not be awarded to the bidder.

The projects must be completed within 24 months.

The successful bidder must set up the wind projects and the transmission network up to the interconnection/delivery point. The power will be primarily supplied to SECI.

The scope of work also includes operation and maintenance services for 25 years.

If the projects are set up in Gujarat and Rajasthan, Torrent Green Energy must abide by the Supreme Court’s orders and the Ministry of New and Renewable Energy’s guidelines on retrofitting of transmission lines and wind turbines to avoid bird collision in the Great Indian Bustard habitat.

The projects will be executed with an investment of ₹26.5 billion (~$309.69 million).

With this project win, Torrent Power’s renewable energy capacity under development has increased to over 3.3 GW.

Torrent Power is an integrated power utility with a power distribution network in Gujarat, Union Territory of Dadra and Nagar Haveli and Daman and Diu, Maharashtra, and Uttar Pradesh.

In 2024, SECI’s 500 MW wind power (Tranche-XVII) was won by by Powerica and Adyant Enersol (a subsidiary of Datta Infra).  Powerica and Adyant Enersol were both awarded  50 MW at tariffs of ₹3.81(~$0.0450)/kWh and ₹3.82(~$0.0451)/kWh respectively.

According to Mercom India Research, India added 1.8 GW of wind energy capacity in the first quarter of the calendar year 2025, an increase of 63% year-over-year from 1.15 GW. The capacity additions rose 134% quarter-over-quarter.
