ReNew Energy Global Plc, a decarbonization solutions provider listed on Nasdaq, has achieved a major milestone by commissioning around 2.4 gigawatts (GW) of renewable energy capacity during the 2025–26 fiscal year. This marks the highest annual capacity addition in the company’s history and strengthens its position as one of India’s leading renewable energy operators.
The newly added capacity includes a mix of solar and wind projects, with about 1.75 GW coming from solar power and 0.62 GW from wind energy. The expansion also features 25 megawatts (MW) and 100 megawatt-hours (MWh) of battery energy storage systems, showing the company’s focus on improving grid stability and integrating storage solutions into its portfolio.
As of March 31, 2026, the company’s total operating capacity has reached around 12.6 GW. This figure comes even after the company completed the strategic sale of 600 MW of assets during the year. Beyond operational assets, ReNew’s total gross capacity, including projects under development and construction, has grown to approximately 20 GW. In addition, around 450 MW of projects have already been built and are expected to become operational soon.
Sumant Sinha, Founder, Chairperson, and CEO of ReNew, described the year as a defining period for the company. He highlighted strong execution and the increasing attractiveness of India’s clean energy sector as key drivers behind this growth. He also pointed out that rising electricity demand and supportive government policies continue to create a stable environment for long-term expansion, even amid global economic uncertainties.
The company has also made progress in the corporate and industrial (C&I) segment through its arm, ReNew Green. This business currently manages 2.5 GW of committed capacity, with more than 2.0 GW already operational. It has partnered with global companies like Google, Microsoft, and Amazon, and recently secured a $95 million equity investment led by LeapFrog Investments.
In manufacturing, ReNew operates 6.5 GW of solar module capacity and 2.5 GW of solar cell capacity. It plans to add another 4 GW of solar cell manufacturing capacity by December 2026, strengthening its supply chain and supporting India’s push for self-reliance in green technologies.
With its current operations, ReNew can supply clean energy to nearly 24 million households and help avoid about 23 million tonnes of carbon dioxide emissions every year, playing an important role in India’s transition to a sustainable energy future.
