O2 Power, Azure Power, Tata Power, and Amp Energy have together won 1,170 MW of projects in NTPC Limited's auction for 1.2 GW of the interstate transmission system (ISTS) connected solar projects. According to Mercom's sources, O2 Power, Azure Power, and Tata Power were awarded 400 MW, 300 MW, and 370 MW of projects, respectively, at a tariff of ₹2.43 (~$0.0325)/kWh. Amp Energy secured 100 MW of projects at ₹2.44 (~$0.0327)/kWh. ReNew Power also placed bids for 300 MW of projects but was not awarded any capacity. Mercom earlier reported that the tender was oversubscribed, but due to some bids not making it through the technical qualifications, only 80% of the received bids were auctioned by NTPC. Background: In February 2020, NTPC floated an invitation for bids for the selection of solar power developers to set up 1.2 GW of ISTS-connected solar projects. The tender was announced with a ceiling tariff set at ₹2.78 (~$0.037)/kWh.
