This report, commissioned by NITI Aayog’s Expert Group, explores the financial, policy, and regulatory measures required to achieve India’s ambitious target of 175 GW renewable energy (RE) capacity by 2022, focusing on scaling up solar, wind, small hydro, and bioenergy. It identifies challenges such as financing, grid integration, and managing RE variability, and outlines potential solutions like accelerated depreciation, generation-based incentives, and interest subvention. Additionally, the report emphasizes the importance of ecosystem-level interventions, including long-term policy stability, institutional capacity building, and reduced project risks, to enable cost-effective RE deployment and ensure tariff reductions for end-users.
