Suzlon Energy Ltd. is a wind turbine supplier based in Pune, India. Formerly ranked as the world's fifth largest supplier,[2] it has since then dropped out of the Global top ten rank as of 2014.[3] The company claims to have over 14,800 MW of wind energy capacity installed globally, with operations across 19 countries and a workforce of over 7,000.[4]

The company is listed on the National Stock Exchange of India (NSE:SUZLONEQ) and on the Bombay Stock Exchange (BSE:532667).

Company structure[edit]

Suzlon is a vertically integrated wind power company. Suzlon makes and installs wind turbines.[5] The company manufactures blades, generators, panels, and towers in-house and large or offshore turbines through its subsidiary Senvion. The company is integrated downstream and delivers turnkey projects through its project management and installation consultancy, and operations & maintenance services. Suzlon has offices, R&D and technology centres, manufacturing facilities and service support centres spread across the globe.

Suzlon has design and R&D teams and facilities in India, Germany, Denmark and The Netherlands. The international sales business of Suzlon is managed out of Aarhus, Denmark, while its global management office is in Pune, India. Suzlon has eight manufacturing facilities across the country, and a workforce of over 10,000 employees globally.


In 1995, founder Tulsi Tanti was managing a 20-employee textile company. Due to the erratic availability of power locally, and its rising costs, the highest business expenditure after the raw materials was electricity.[6] The cost of electricity also offset any profits made by the company.[7] After providing electricity for his own company, Tanti moved into wind energy production as a way to secure the textile company's energy needs, and founded Suzlon Energy.[8] Suzlon adopted a business model wherein clients would be responsible for 25% of the up-front capital investment and Suzlon would arrange the remaining 75% on loan. Initially banks were hesitant to fund loans for this model, but by 2008 40-50 Indian banks were financing wind power projects for Suzlon clients.[6]

In 2001, Tanti sold off the textile business; Suzlon is still actively run by Tulsi Tanti, now in the role of Chairman, Suzlon Group.

In 2003, Suzlon got its first saddles order in USA, with an order from DanMar & Associates to supply 24 turbines in southwestern Minnesota.[9] Also in 2003 Suzlon set up an office in Beijing.[6]

Suzlon Rotor Corporation in 2006 began producing the blades in Pipestone, Minnesota in the United States. Among its clients is Wind Capital Group.[10]

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 Senvion (then operating as REpower Systems) 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 megawatts 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.[11][12][13]

In January 2011, Suzlon received an order worth US$1.28 billion for building 1000 megawatts of wind energy projects from the Indian branch of the Lord Swaraj Paul-owned Caparo Energy Ltd.[14]

In May 2011, Suzlon announced returning to profitability after the financial crisis of 2009 [15]

In October 2011, Suzlon sold its remaining 26.06% stake in Hansen Transmissions International NV to ZF Friedrichshafen AG for 8.9 billion (US$140 million). [16] In the same month, it also achieved full control of its German subsidiary REpower Systems (now Senvion) by acquiring the remaining 5% stake held by minority shareholders that resisted the takeover. The takeover was completed through the squeeze-out procedure by paying EUR 63 Million. [17]

It has to redeem 500 million worth of FCCB's (foreign currency convertible bonds) in 2012 in tranches of 300 million in June and 200 million in October respectively. In line with the previously announced strategy to dispose of non-critical group assets to reduce long-term debt, Suzlon Chairman said that Suzlon Energy, will sell stake in its China manufacturing unit to China Power New Energy Development Company Limited for 3.4 billion rupees ($60 million).[18]

On 30 November 2013 the Suzlon Group subsidiary REpower Systems (now Senvion SE) won an Engineering, Procurement and Construction (EPC) contract from Mitsui & Co (Australia) Ltd to deliver 52 wind turbines with a total rated output of 106.6 MW for the Bald Hills wind farm in Victoria, Australia.[19]

As of August 2014, Suzlon's debt was over 8000 crores.[20] On 22 January 2015, Suzlon announced the sale of Senvion SE, its wholly owned subsidiary, to Centerbridge Partners, a private equity firm in a deal valued at 7200 crores.[21] The deal is expected to ease Suzlon's debt burden.[21] In a further equity infusion, Dilip Shanghvi Family and Associates (DSA), run by Dilip Shanghvi, the founder and managing directory of Sun Pharmaceutical, agreed to purchase a 23 percent stake in Suzlon for a sum of 1800 crores.[22] The deal will see Tanti's holding shrink to 24 percent, but management control will still remain with the Tanti family.[22] Its total borrowings stood at Rs 11430.76 crore in FY16 from Rs 17810.96 crore FY15.[23]

On 17 January 2017 - Suzlon Energy achieved 10,000 megawatts installed wind energy milestone in India. Suzlon's 10,000 MW of wind installation is capable of powering over 5 million households per annum and offsets approximately 21.5 million tonnes of Carbon Dioxide (CO2) emission annually which is equivalent to planting over 1500 million trees. [24]

Wind parks[edit]

Globally, Suzlon has installed over 25000 MW of wind power capacity in 31 countries.[25]


Suzlon crossed 10,000 megawatts of cumulative installations in India. [26] Suzlon has cumulatively added over 7,600 megawatts of wind power capacity for over 1,700 customers in India across 40 sites in eight States. Suzlon accounts for nearly half of the country's total wind installations.[27]

Its notable installations in India include:

In 2012, Suzlon signed an Expression of Interest with the government of Karnataka to develop 2500 MW of wind power in the state between 2012 and 2017.[33]
