The tender was oversubscribed yet again with total capacity bids reaching 2,325MW.
Ostro Energy, a part of ReNew Power, (300MW), Adani Renewables (250MW), Srijan Energy, a unit of Continuum backed by Morgan Stanley (150MW), Powerica (50.6MW) all won capacity at INR 2,820/MWh ($39.5/MWh).
SB Energy backed by Japanese financer Softbank, and Ecoren Energy bid for 600MW and 125MW, respectively, for a tariff of INR 2,830/MWh ($39.64/MWh).
However, SB Energy was allocated only 324.4MW, the balance left from the 1.2GW on offer.
Other unsuccessful bidders included ReNew Power (300MW), Engie (250MW), Enel (300MW), and EDF Renewables (300MW).
The results of the tender indicate revival of interest from the government and the developers, particularly foreign players.
The significant increase in tariff from INR 2,760/MWh ($38.66/MWh), discovered in the fifth auction awarded in September, suggested project developers may be moving to states, other than Gujarat and Tamil Nadu, with weaker wind regimes.
On the heels of the sixth tender, SECI has already announced the seventh federal tender for a further 1.2GW.
In line with the past tenders, the tender has set a ceiling tariff of INR 2,830/MWh ($39.64/MWh) and has set maximum individual bid capacity of 600MW.
SECI also expanded its mandate beyond onshore wind by signing an agreement with the Gujarat government to conduct auctions for a 1GW offshore wind project.
India has been quite keen on developing offshore wind power projects off the state of Gujarat.
The Ministry of New and Renewable Energy (MNRE) issued an Expression of Interest from offshore wind energy developers last year.
This drew interest from more than 30 companies including Greenko, Mytrah Energy, Inox Wind, Suzlon Energy, and ReNew Power plus a host of foreign firms like Ørsted, Alfanar, E.on, Macquarie Group, Shell, and Senvion.
