US based SunEdision Inc has won a bid to sell solar power in India at a record low tariff of 4.63 rupees ($0.0706) per kilowatt-hour, an Indian government official said, which could make the renewable energy cheaper than fossil fuel-derived electricity. The company won the auction for a 500 megawatt project in the southern state of Andhra Pradesh, Upendra Tripathy, new and renewable energy secretary, told Reuters on Wednesday. The previous low was 5.05 rupees per kilowatt-hour, he said. SunEdision could not immediately be reached for comments outside regular US business
