KP Energy, Ganeko Three Energy (an SPV of Zelestra), Waaree Forever Energies (a subsidiary of Waaree Energies), Opera Energy, Purvah Green Power, Vena Energy Aura (a subsidiary of Vena Energy), and Refex Holding have won Solar Energy Corporation of India’s (SECI) auction to develop 1.2 GW of interstate transmission system (ISTS)-connected wind power projects across India under Tranche XIX.

KP Energy was awarded 100 MW at a tariff of ₹3.67/kWh (~$0.405/kWh). Ganeko Three Energy, Waaree Forever Energies, and Opera Energy won 180 MW, 300 MW, and 50 MW, respectively, at a tariff of ₹3.68 (~$0.0407)/kWh.

Purvah Energy and Vena Energy Aura won 250 MW and 124 MW, respectively, at ₹3.69 (~$0.0408)/kWh, while Refex Holding secured 196 MW under the bucket-filling method, also at ₹3.69 (~$0.0408)/kWh.

The tender was floated in October last year for a total capacity of 600 MW. In December, the capacity was increased to 1.2 GW.

The projects can be located anywhere in India. The selected bidders must sign a power purchase agreement (PPA) with SECI for 25 years.

The scope of work includes setting up the wind projects and establishing the transmission network up to the interconnection or delivery point. It also involves land identification, securing ownership, and obtaining all approvals and clearances from state and local authorities.

The project developers must conduct site selection at their own discretion and cost. Each project must be connected to the ISTS grid at a minimum voltage level of 220 kV.

The scope of work also includes operation and maintenance of the projects for the PPA period.

In June last year, Torrent Green Energy won SECI’s auction to set up 600 MW ISTS-connected wind power projects under Tranche XVIII. Torrent has won 300 MW at a tariff of ₹3.97 (~$0.046)/kWh. Of the 600 MW tendered, only 300 MW were awarded because the eligible bids received were significantly lower than the floated capacity.

Earlier, SECI’s 500 MW wind power (Tranche-XVII) was won 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.

India added 6.3 GW of wind power capacity in 2025, an 85.2% YoY increase from 3.4 GW in 2024, according to Mercom India Research. The additions marked the highest annual wind installations recorded in the country. India’s wind power market improved in 2025, supported by higher tender activity, stronger bidder participation, and more competitive tariffs.
