The government plans to auction wind power projects of about 4 gigawatt (GW) capacity in tranches this year, a senior official said on Friday. “The first batch of such auction is being planned next month,” said Ashvini Kumar, managing director, Solar Energy Corporation of India. The SECI is the nodal agency for holding the auctions this fiscal, part of government’s plan to set up wind power capacity of 60 GW by 2022. “There should be auction of 5-6 GW wind power capacity every year after this fiscal for meeting the target of 60 GW wind energy by 2022,” Kumar said. The government has decided to go the bidding route as the first ever auction of wind power projects in February 2017 had seen power tariffs falling to all-time low of 3.46 per unit. Wind power capacity of 1 GW was auctioned by SECI in February. Power minister Piyush Goyal in February had indicated that the government could go for more such auctions in future as the average wind tariff, that was hovering above Rs 5 per unit earlier.
