The Government of India, through its Jawaharlal Nehru National Solar Mission (JNNSM), Modified Special Incentive Package Scheme (MSIPS), National Manufacturing Policy (NMP) and Make in India, has announced several measures and incentives favouring renewable manufacturers. The National Wind Mission and the Renewable Energy Law also include a variety of measures that would benefit domestic manufacturers. This report comprehensively examines the manufacturing supply chain of different components used in Renewable Energy (RE) systems, especially wind and solar technology, in India. The study proposes several measures in finance, standards and benchmarking, materials and technology, and research and development to promote and support domestic manufacturing in solar and wind technology. In addition, interventions to address issues such as local content requirement, export promotion, auxiliary industry promotion and logistical challenges (in the case of wind technology) have also been proposed. A component-wise policy recommendation concludes the study.
