was installed in India. To reach the goal of 100 GW of installed solar capacity by 2022, Modi's government has set a target to auction at least 77 gigawatts of additional solar power capacity by March 2020. A total of 1.2 GW of solar power is tendered in the first week of 2018 and a solar power tender of 20 GW, world's largest so far, is to be auctioned off in one go in 2018. Several large grid-scale solar parks are in operation, several of which are among the world's largest such as Kurnool Ultra Mega Solar Park with the capacity of 1,000 MW, the Kamuthi Solar Power Project with the capacity of 648 MW, the 345 MW Charanka Solar Park, the 480 MW Bhadla Solar Park with a proposed capacity of 2,255 MW and the Gujarat solar parks with a combined capacity of 605 MW. In July 2017, Indian Railways rolled out trains with rooftop solar to power the lights, fans and displays inside the coaches. Cochin International Airport, seventh busiest in India, is the first one in the world to run entirely on solar power, handling more than 1,000 flights a week. Similarly, the Union Territory of Diu is fully run by solar power. Solar power features prominently in Modi government's US$2.5 billion SAUBHAGYA scheme launched in July 2015 to electrify every Indian household by 2019 — a huge task considering around 300 million people were without electricity. The use of local mini-grids run on solar power is “a big part of the push, with 60 percent of new connections expected to be to renewable power", according to a report by the International Energy Agency. The government provides subsidy of up to 90% of the upfront capital cost to install solar-powered water pumping systems for irrigation and drinking water.[32] As of 30 November 2017, more than 142,000 solar pumps have been installed to irrigate the agricultural fields.[33] This scheme weans farmers away from diesel-powered pumps and generates extra income for them by allowing to sell surplus power to the grid. It is one of the innovative ways that the government is empowering the rural population with the help of solar energy by addressing specific issues such as water availability. The solar panels are being built over the irrigation canals to preserve water from evaporation in drought-prone sunny areas. The world's first canal-top solar project was set up on
