The challenges were stark in the case of Adani Green (ADNA.NS), India's largest renewable energy company, which took nearly 3-1/2 years to strike supply deals with buyers for the entire 8 gigawatts (GW) of solar power capacity it won in a tender widely publicised as the country's biggest.

Gautam Adani was charged with allegedly paying US$265 million in bribes related to power supply contracts in Indian states.

India's renewable energy output has seen growth, with solar generation reaching 115.97 TWh in 2023, up from 102.02 TWh in 2022, as per Global Data insights. However, renewables still account for only 21.6 per cent of the country’s total electricity generation, indicating that much work remains to meet the nation’s clean energy targets.
