Solar power in India is a growing industry. As of 6 April 2017, the country's solar grid had a cumulative capacity of 12.28 GW. India quadrupled its solar-generation capacity from 2,650 MW on 26 May 2014 to 12,289 MW on 31 March 2017. Solar power tariffs in India have found a new floor at Rs 2.97 per unit, sinking below the average cost of Rs 3 for electricity supplied by state-run generation utility NTPC from its coal-fired plant.

India’s solar power tariff hit a new low of Rs2.44 per unit on Friday at the auction of 500 megawatt (MW) of capacity at the Bhadla solar park in Rajasthan. The tariff Rs2.44 per kilowatt-hour (kWh) and Rs2.45 per kWh which is a "Historic low tariff for India,”

“Green future": Latest solar power auction at Bhadla Solar Park 3 sets "new record with electricity tariff of Rs2.44/unit,” Piyush Goyal, minister for new and renewable energy, power, mines and coal, said in a tweet.

The last recorded lowest tariff was Rs2.62 per kWh discovered earlier for Adani Power’s 250 MW solar park, also being developed at Bhadla.
