From 0 to 10 GW: How Sumant Sinha’s ReNew Power turned India’s energy future green, listed on NASDAQ and is now cutting green-hydrogen costs by 30%
In 2011, when the world still largely regarded solar and wind energy in India as experimental, ReNew Power (now “ReNew”) was founded by Sumant Sinha with a bold vision: to build India’s largest clean-energy company and accelerate the shift to a fossil-free future.
Today, ReNew stands tall as one of India’s most influential clean-energy firms, generating nearly 10 gigawatts (GW) of wind and solar power — a major step in the country’s renewable transition. Sinha’s leadership has transformed ReNew into a global player that blends business strategy with climate responsibility.
The company’s journey began modestly with a 25 MW wind project in Gujarat. Drawing on Sinha’s background in finance and his experience in corporate leadership, ReNew raised early capital to scale operations across India. Within a decade, the company became India’s largest renewable-energy producer.
In 2021, ReNew achieved a historic milestone — becoming one of the first Indian renewable-energy companies to list on NASDAQ, with a valuation of nearly US $8 billion. This marked a turning point, showcasing the confidence global investors had in India’s clean-energy growth story.
By 2025, ReNew’s revenues exceeded US $2 billion, underscoring its position as a key player in India’s energy transformation. Yet, scale alone is not the story — innovation is. Under Sinha’s direction, ReNew has expanded its focus beyond just generating clean power to investing in green hydrogen, energy storage, and digital decarbonisation solutions.
One of its most notable breakthroughs lies in green hydrogen — a fuel produced using renewable electricity. Through extensive research and pilot projects, ReNew has managed to cut the cost of green-hydrogen production by around 30%, a leap that could redefine clean industrial energy in India. This move positions ReNew as a technology-driven decarbonisation partner rather than just a power-producer.
ReNew’s transformation reflects a broader strategy — moving up the clean-energy value chain. From building solar parks and wind farms to integrating electrolyser technology, manufacturing, and digital monitoring systems, the company is driving a holistic approach to sustainable energy.
Sumant Sinha has also been a strong voice in India’s global energy diplomacy, advocating for unified carbon pricing, renewable financing, and large-scale manufacturing of clean-tech equipment within India. ReNew’s operations now span over 10 Indian states, managing more than 150 utility-scale projects and impacting industries ranging from heavy manufacturing to agriculture.
Of course, challenges remain. Renewable-energy companies like ReNew must navigate fluctuating tariffs, power-purchase agreements, and grid-integration issues while maintaining profitability. However, its focus on research, efficiency, and diversification gives it a competitive edge in an increasingly crowded sector.
Looking forward, ReNew’s push into green hydrogen may be its most ambitious bet yet. If its cost-cutting success continues, it could transform sectors like steelmaking, fertilizers, and transportation — making India a global hub for low-carbon industries.
In many ways, the story of ReNew Power is a story of modern India itself: innovative, forward-looking, and determined to lead the global clean-energy transition. From a single wind farm in Gujarat to a multi-billion-dollar, NASDAQ-listed renewable giant, ReNew Power stands as proof that sustainability and scale can go hand in hand.
Whether it’s solar, wind, or hydrogen, ReNew Power under Sumant Sinha is not just producing clean energy — it’s powering the future of India’s green economy.
