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

The Ministry of New and Renewable Energy (MNRE) issued guidelines setting the validity of the prototype certificate for a wind turbine at three years. The guidelines include a framework for installing prototype wind turbine models. They will apply to all wind turbine manufacturers in India and will be implemented by the National Institute of Wind Energy, Chennai.

The Central Electricity Regulatory Commission (CERC) approved tariffs of ₹3.25 (~$0.037)/kWh and ₹3.26 (~$0.038)/kWh for Solar Energy Corporation of India’s (SECI) 600 MW interstate transmission system-connected wind-solar hybrid power projects (Tranche IX). CERC, however, refused to award a trading margin of ₹0.07 (~$0.008)/kWh. It stated that since the awarded capacity had not yet been tied up, the trading margin would be determined according to the power sale agreement that would be signed between SECI and the distribution licensees.
