Suzlon was founded by Tulsi Tanti, who had originally run a textile business in Gujarat. Faced with unreliable and expensive grid power, Tanti installed wind turbines for captive use, an experience that led him to set up a dedicated wind energy company. Suzlon began by importing turbine technology and gradually built indigenous design, manufacturing and project execution capabilities, positioning itself as an integrated wind energy company offering end-to-end solutions from site identification to long-term operations and maintenance.
Suzlon manufactures wind turbine generators across multiple capacity classes, along with key components such as rotor blades, nacelle covers, tubular towers and control systems. Its manufacturing facilities are located in several Indian states, including Gujarat, Tamil Nadu and Daman. The company also provides:
Suzlon has installed wind capacity for utility, independent power producer and corporate customers, and its turbines have been deployed in countries across Asia, Europe, the Americas, Africa and Australia.
Suzlon is widely regarded as a pioneer of India's modern wind energy industry. By developing domestic manufacturing for wind turbines and large utility-scale wind farms, it helped establish wind power as a mainstream component of India's electricity mix and supported the country's renewable energy targets. Its rise also marked one of the earliest cases of an Indian engineering company building a globally competitive position in clean technology through cross-border acquisitions, while its later financial difficulties became a frequently cited example in studies of leveraged international expansion by Indian firms.
