India’s clean energy push is no longer emerging; it is defining the global transition. The country added a record 55.3 GW of non-fossil capacity in the starting of FY26, taking its total to 283.46 GW and overtaking Brazil to become the world’s third-largest renewable energy market. Solar alone contributed 44.61 GW in a single year, while renewables met over 51 percent of peak electricity demand in July 2025, signaling a structural shift in how India generates and consumes power.

Leading this momentum are some of the largest renewable developers in India, including Adani Green Energy Limited, ReNew Power, Sterling and Wilson Renewable Energy Limited, Tata Power Renewable Energy Limited, and NTPC Green Energy Limited. These companies are scaling capacity across solar, wind, hybrid, and storage projects, driven by strong pipelines, EPC capabilities, and integrated energy solutions.

Here’s the state-wise breakdown for Azure Power Global Limited:

Growth of the renewable energy sector in India 2026

India’s renewable energy sector entered a record growth phase in FY26, driven by strong policy backing, rising electricity demand, and rapid project execution. The country added 55.3 GW of non-fossil fuel capacity during the year, nearly doubling the 29.5 GW added in FY25. This pushed total non-fossil installed capacity to 283.46 GW as of March 2026, allowing India to surpass Brazil and rank third globally, behind China and the United States.

Record capacity addition and global position

Solar energy remained the primary growth engine, accounting for the majority of new capacity additions. India’s cumulative solar capacity reached 150.26 GW, with a record 44.61 GW added in FY26 alone. This exceeded government targets and nearly doubled the additions in the previous year. 

Utility-scale projects continued to dominate, but distributed solar saw significant traction, contributing 16.31 GW, or about 36 percent of total solar additions. This included strong growth in rooftop installations and agricultural solar under government-backed programs. The expansion of distributed solar indicates a shift toward decentralized energy systems, reducing grid dependency and improving energy access.

Policy push and government initiatives

Government initiatives played a critical role in accelerating deployment. Programs such as PM Surya Ghar Yojana and PM KUSUM Scheme drove large-scale adoption across residential and rural segments. The PM Surya Ghar program alone reached over 3.4 million households, with a target of 10 million installations by FY27. 

Meanwhile, KUSUM installations more than doubled year-on-year, reaching a cumulative capacity of 13.1 GW. Policy refinements, including updated guidelines and extended timelines for project execution, helped address financing and operational challenges, improving overall sector momentum.

Wind energy also recorded its strongest annual performance, with 6.05 GW of new capacity added in FY26, a 46 percent increase from the previous year. Total installed wind capacity crossed 56 GW, placing India among the top global markets. 

Growth in this segment was largely driven by commercial and industrial consumers, which accounted for nearly 75 percent of new additions. This reflects a broader trend of corporate decarbonization, where industries are increasingly adopting renewable energy through captive and open-access models.

Manufacturing and infrastructure scale-up

Beyond generation capacity, India made significant progress in manufacturing and supply chain development. Solar module manufacturing capacity more than doubled from around 74 GW in FY25 to 172 GW in FY26, strengthening domestic production and reducing import dependence. Wind turbine manufacturing capacity also reached about 24 GW. 

At the same time, investments in transmission infrastructure, supported by government funding, improved grid readiness to handle higher renewable penetration. These developments are critical for maintaining grid stability as renewable capacity continues to scale.

Power generation trends and key milestones

Electricity generation trends further highlight the transition. Total power generation reached approximately 1.85 trillion units in FY26, of which 29.2 percent came from non-fossil sources. In July 2025, renewables met over 51 percent of peak electricity demand, marking a key milestone in India’s energy transition. 

Notably, the country achieved 50 percent of its installed power capacity from non-fossil sources in June 2025, five years ahead of its Paris Agreement target. Looking ahead, India aims to increase this share to 60 percent by 2035 while significantly reducing emissions intensity, reinforcing its position as one of the fastest-growing renewable energy markets globally.

A breakdown of India’s non-fossil capacity highlights the dominance of solar and the growing contribution of other clean sources:
