Tulsi Tanti is the chairman and managing director of Suzlon Energy, a US $2 billion market capwind power based company. He, along with his three siblings, own 58% of the company.He is from Rajkot, Gujarat where he started his first venture which was in textiles in Surat called Sulzer Synthetics P. Ltd. later changed name Suzlon Synthetics Ltd. And there after Suzlon Fibres Ltd., then he moved into wind energy production and founded Suzlon Energy. He was worth $930 million as per Forbes in November 2008. However an 85% drop in share price of his Suzlon Energy, precipitated by the global recession and reliability issues with Suzlon's wind turbine blades, caused his net worth to drop to $400 million.
In 1990, Tulsi Tanti invested in two Vestas wind turbines and realized their huge potential. In 1995, he formed Suzlon and gradually quit textiles. Suzlon Energy is the fifth largest wind turbine manufacturer in the world (combined with REpower) and the largest in Asia. It is presently building what will be among the world's largest wind parks of its kind at 1,000 MW capacity.
Suzlon is currently concentrating on a global expansion drive. In 2006, it acquired Hansen Transmissions, a Belgian maker of wind-turbine gearboxes, which it subsequently sold to ZF Friedrichshafen in 2011. Suzlon is also building a rotor-blade factory in Minnesota and has invested $60m in a factory in Tianjin, China.
