India’s Solar Surge Generates 16,811 MU, Contributing ~70% To Renewable Energy In March 2025

In March 2025, India reached a major milestone in its renewable energy journey, with solar power making up nearly 69.64% of the country’s total renewable energy generation, excluding large hydropower. The country generated 16,811.38 million units of solar energy, showing a strong focus on clean and sustainable power. This growth was supported by government policies, financial incentives, and improvements in solar technology.

By the end of March 2025, India’s total renewable energy capacity, excluding large hydropower, reached 172,368.18 MW. Out of this, solar power contributed 105,646.49 MW, showing a sharp rise in solar adoption and strengthening India’s position in the global renewable energy sector. This increase was due to more project installations, better photovoltaic system efficiency, and strong financial support from both the public and private sectors.

Wind energy also played a key role, contributing 21.26% of the total renewable generation in March 2025. Wind farms produced 5,133.63 million units of electricity, backed by an installed capacity of 50,037.82 MW. While there was a slight increase in wind power generation compared to last year, it continues to face seasonal challenges. Unlike solar, which benefits from longer daylight hours during summer, wind power varies with monsoon patterns and regional wind speeds. This makes it difficult to maintain a steady supply and highlights the need for better forecasting, energy storage, and grid flexibility.

Other renewable sources like biomass, bagasse, and small hydropower made up 9.1% of the total renewable energy generation. Even though their share is smaller, they help in creating a balanced and reliable energy mix. A mix of different renewable sources is important to reduce the risk of relying too much on one source. In total, India generated 24,141.26 million units of renewable energy in March 2025, excluding large hydropower. This was a 19.55% rise from February and a 25.19% increase compared to March 2024. The growth in solar generation was supported by longer daylight and stronger sunlight in the summer, while wind energy faced seasonal limits.

While solar power continues to grow rapidly, the drop in wind production raises concerns about supply stability. To address this, India needs to focus more on energy storage and better grid management. The country aims to reach 500 GW of renewable capacity by 2030, but issues like financing, grid integration, and transmission need attention. Working together on storage systems, smart grids, and steady policies will be key to meeting these goals.
