Continuous innovation, a hallmark of Suzlon, led to the development of the S9X suite of wind turbines, which were launched to a global audience at the AWEA Wind Power 2011 conference。 Improvising on its product offering, the company produced a variant – the S97 2。1MW wind turbine generator (WTG), built with a hybrid tower (lattice/tubular combination) and a hub-height of 120 meters in 2012。
The S111 2。1MW WTG suite, part of the S9X series, also received certification from TÜV NORD for its 50 Hz and 60 Hz variants in 2015。 This certification was awarded for conforming to standards and regulations for design, testing, and manufacturing of the WTG。
New investors, impressed with Suzlon’s growth story, also joined hands. In 2015, Suzlon signed definitive agreements with Dilip Shanghvi Family and Associates (DSA) for equity investments of Rs.1,800 crore in Suzlon Energy Limited for equity infusion to accelerate growth. Suzlon attained other major milestones too during the period. It commissioned its 10,000th WTG at the Artilleros wind farm in Uruguay.
Suzlon’s landmark initiatives, Pure Air Lovers' Society (PALS) and a state-of-the-art training centre for wind technicians in North America were successful in their objectives – creating a community of people supporting wind energy in the case of PALS and preparing for future manpower needs in the latter case。
