1 GW Auction Yields India’s Cheapest Wind Power At 5.2¢/kWh

Four developers secured rights to develop a cumulative of 1,000 megawatts in first-ever wind energy auction held in India.

According to media reports, the four project developers were allocated 250 megawatts capacity each at a tariff of Rs 3.46/kWh (5.2¢/kWh) in the auction organised by the Solar Energy Corporation of India. Mytrah Energy, Green Infra, Inox Wind and Ostro Energy were the successful bidders.

Mytrah Energy and Green Infra are expected to set up projects in the state of Tamil Nadu while Inox Wind and Ostro Energy would likely set up projects in the state of Gujarat. The companies shall sell electricity generated to Power Trading Corporation of India which will in turn sign power sale agreements with interested utilities across the country.

All companies except Inox Wind are project developers while Inox Wind is a turbine manufacturer. Another project developer Adani Enterprises also placed a bid of Rs 3.46/kWh (5.2¢/kWh) but could not get any capacity allocation.

The tariff discovered in the auction is lower than feed-in tariff offered by any state. The lowest tariff offered is Rs 4.16/kWh (6.2¢/kWh) in Tamil Nadu, although Rs 3.82/kWh (5.7¢/kWh) is also offered in the state of Maharashtra at sites with low wind speeds.

Apart from Inox Wind, another turbine manufacturer participated in the auction. Gamesa India quoted a tariff of Rs 3.68/kWh (5.5¢/kWh) and failed to make the cut. ReNew Power Ventures, one of the leading project developers in India, also failed to grab any capacity as it quote a tariff of Rs 3.47/kWh.

Wind follows solar’s trend

The sharp correction in the price of wind power comes just days after India saw its lowest ever solar power tariff in an auction of 750 megawatts capacity. Solar power tariffs in the auction for Rewa solar power park collapsed from previous low of Rs 4.34/kWh (6.5¢/kWh) to Rs 2.97/kWh (4.5¢/kWh) although the levellised tariff for 25 years period will be Rs 3.30/kWh (4.9¢/kWh).

Indian bids in-line with global trends

The tariff bids seen in India’s first-ever auction are in-line with those prevalent in other markets. According to the International Renewable Energy Agency (IRENA), tariff bids for wind energy projects have converged around 4.0¢/kWh. Auctions held in Mexico, Egypt, Chile and Morocco were around the 4.0¢/kWh mark. Interestingly, tariff bids in developed countries – United Kingdom, Italy, Australia and Canada – were above 6.0¢/kWh.
