India’s leap toward a sustainable energy future hinges on forward-thinking firms expanding renewable energy capacity, pioneering technology, and driving large-scale impact. Here’s a curated list of the top ten companies transforming India’s clean energy landscape:
1. Adani Green Energy Ltd. (AGEL)
One of India’s largest renewable energy firms, AGEL leads with a diversified portfolio across solar, wind, and hybrid projects. As of 2025, it commands over 13 GW in installed capacity, targeting 50 GW by 2030. Its ambitious roadmap and mega solar parks in Rajasthan and Gujarat underline its dominant role in India’s green transition.
2. Tata Power Renewable Energy Ltd. (TPREL)
Tata Power’s renewable arm focuses on solar, wind, hydro, rooftop solar, and EV infrastructure. With approximately 10.9 GW installed, TPREL is pushing for 70% renewable energy penetration by 2025, showcasing strong innovation and national reach.
3. ReNew Energy Global (ReNew Power)
A leading independent power producer, ReNew operates 10–10.6 GW of renewable capacity across solar, wind, and hydro. It’s expanding toward 19 GW by end-2025, and its innovation in green hydrogen and energy storage positions it at the forefront of India’s energy evolution.
4. Greenko Group
Greenko’s strengths lie in hybrid energy solutions and pumped hydro storage, stabilizing the grid amid growing renewables. With over 7 GW in clean energy assets, Greenko is pivotal in balancing India’s rapidly expanding green grid.
5. Suzlon Energy
A premier wind turbine manufacturer, Suzlon has installed over 20 GW globally and maintains a strong presence in India and overseas. Its R&D investments continue to shape wind energy efficiency and deployment.
6. Azure Power Global
Azure Power, with over 7 GW of solar assets, develops utility-scale projects paired with stable PPAs. Known for its reliability and execution, the company is critical to India’s solar adoption.
7. NHPC Limited
A hydropower giant, NHPC now also invests in solar, wind, and pumped storage. With 7+ GW in renewable capacity, it combines hydro legacy with new-age renewables.
8. JSW Energy
JSW is expanding its renewable portfolio and venturing into green hydrogen. Aiming for 20 GW capacity by 2025 and carbon neutrality by 2050, the company exemplifies future-focused energy diversification.
9. Hero Future Energies
As part of the Hero Group, this firm plans a staggering $20 billion investment to scale its renewable capacity from 1.9 GW to 30 GW by 2030, leveraging global investor support.
10. Emmvee Group
A Bengaluru-based powerhouse in solar manufacturing, Emmvee has ramped up to 6.6 GW of module capacity and 2.5 GW of solar cell output. Its vertically integrated model and R&D boost India’s solar self-reliance.
