Indian firm ReNew Energy Global Plc commissioned approximately 2.4 gigawatts of renewable energy capacity in the fiscal year ended Mar. 31, its highest-ever annual addition, lifting its total operating portfolio to about 12.6 GW, the second-largest in India, the company said in a statement on Wednesday.
The figure reflects an adjustment for 600 megawatts of assets sold during the year. The newly commissioned capacity includes around 1.75 GW of solar, 0.62 GW of wind, and 25 MW/100 MWh of battery energy storage systems. The company added that roughly 450 MW of fully constructed capacity is expected to be commissioned soon. Its total gross capacity stood at about 20 GW at fiscal year-end.
ReNew, which has operated in India's clean energy sector for more than 15 years, continues to expand across both utility-scale and commercial and industrial segments. Its commercial and industrial arm, ReNew Green, has about 2.5 GW of committed capacity, with more than 2.0 GW already operational. The division counts major global firms, including Microsoft, Amazon, and Google, among its partners. In March 2026, ReNew Green secured $95 million in equity funding from a consortium led by LeapFrog Investments.
In solar manufacturing, ReNew reported 6.5 GW of module capacity and 2.5 GW of cell capacity currently in operation, with plans to expand cell capacity by an additional 4 GW by December 2026.
During FY2026, its facilities produced over 4.1 GW of modules and nearly 1.86 GW of cells. Earlier in the year, the manufacturing business received a $100 million equity investment from British International Investment.
The company operates more than 150 renewable energy sites and three solar manufacturing facilities across 10 Indian states, employing roughly 4,500 people. At its current operating capacity, ReNew said it generates enough clean energy to power approximately 24 million households and avoid about 23 million tonnes of carbon dioxide equivalent emissions annually.
