Suzlon Energy (BSE: 532667, NSE: SUZLON) is a global wind power company based in India. In terms of market share, the company is the fifth largest wind turbine manufacturer in Asia (and the 8th largest worldwide). In terms of net worth, it is the world's most valuable wind power company, but measured by market value, the company is smaller than Vestas and possibly GE, Gamesa Corporación Tecnológica, Enercon and Siemens, of which the market value is harder to know because they are not traded as independent entities.

Suzlon was founded by Tulsi Tanti in 1995, when he was working in a family-owned textile company. In that year, India's shaky power grid and the rising cost of electricity offset any profits the company would make. With the help of some of his friends of Rajkot, he moved into wind energy production as a way to secure the textile company's energy needs, and founded Suzlon Energy. In 2001, Tanti sold off the textile business, so he could focus on the development of his wind energy business. In 2009, Suzlon is still actively run by Tulsi Tanti, now in the role of Chairman and Managing Director.
In 2003, Suzlon got its first sale in USA, with an order from DanMar & Associates to supply 24 turbines in southwestern Minnesota.
Suzlon Rotor Corporation in 2006 began producing the blades in Pipestone, Minnesota in the United States. Among its clients is Wind Capital Group.
In the year 2006, Suzlon reached a definitive agreement for acquisition of Belgium firm Hansen Transmissions, specializing in gearboxes for wind turbines, for $565 million. In 2007, the company purchased a controlling stake in Germany's REpower which valued the firm at US$ 1.6 billion.
In June 2007, Suzlon had signed a contract with Edison Mission Energy (EME) of US for delivery of 150 wind turbines of 2.1 MW in 2008 and a similar volume to be delivered in 2009. EME had an option not to purchase the 150 turbines due to be delivered in 2009, which it has chosen to exercise.
In November 2009, the company decided to sell 35% stake of Hansen for $370 million as part of its debt restructuring program, through placing new shares. It appointed Bank of America Merrill Lynch and Morgan Stanley as the managers and book runners for the same.
In January 2011, Suzlon received an order worth $1.28 billion for building 1000MW of wind energy projects from the Indian branch of the Lord Swaraj Paul-owned Caparo Energy Ltd.
