Solar tariffs jumped to Rs 3.48 per unit at the latest auctions for 1,000 MW, conducted by the Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA), on account of higher land costs and lower irradiance in the region. According to people close to the development, Mahoba Solar (UP), an Adani Group firm, quoted the lowest tariff of Rs 3.48\/kWh to develop 250 MW of projects.
