The Suzlon Group STRONG product backed by proven performance, efficient processes, and a customer focused team, under the umbrella of a global company with local reach. Suzlon is one of the leading manufacturing groups in the world, with a presence in 32 countries on six continents and over 17 GW of installations. While S9X's hallmark is its variable speed technology, the company's holistic design strategy was developed with strong features and components based on the experience of more than 8,000 wind turbines that Suzlon has installed globally. The Started in 1995 in India, the group is today a true multinational organization committed to sustainability. inherent company culture of ongoing client interaction has allowed for transparent customer dialogue and specific input regarding the S9X product development. With a philosophy of sustainable ecological, economical and social development at its heart the group today employs more than 13,000 people of over 35 nationalities in wind turbine and wind turbine component R&D, manufacturing, sales, development, OMS and project management services. Over 4,100 MW of S88 wind turbines across 11 countries S9X: Making profitable and efficient wind energy Spain 233.1 MW China accessible 2.1 MW Sweden As the high wind speed sites across the world become saturated the focus has shifted to providing efficient wind turbine 4.2 MW solutions that operate at a lower wind spectrum. Suzlon's S9X wind turbines meet these needs.

Taking into consideration the stated dynamics of wind energy, Suzlon has created the S9X suite of turbines - S95 and S97, with a 2.1 MW rating for all markets, which is an evolutionary advancement over the successful S88 wind turbine. The S9X's design starts with the current S88, boasting over 4,100 MW of installed capacity in 11 countries and globally averages over 97% availability, making it Suzlon's most robust turbine until now. USA Portugal 2,274.3 MW 102.9 MW Key inclusions in the S9X design are:

1. DFIG convertor featuring variable speed Nicaragua 2. Larger swept area with rotor diameters; 95 and 97 meters 63 MW 3. 80-meter, 90-meter and 100-meter hub heights India 470.4 MW Brazil 384.3 MW Turkey 31.5 MW

Bulgaria Australia Doubly Fed Induction Generation 12.6MW 594.3 MW

Suzlon’s S9X wind turbines utilize well-proven DFIG technology that has been deployed in more than 5,000 units around the world. Vetted through Suzlon’s S9X Suzlon's talent value chain truly optimizes wind farm operations. From the start, the knowledgeable, can-do sales team is by prototype phase, the SEG Woodward’s CONCYCLE Power Convertor System has your side through the complex stages of a wind power project and is strongly supported by outstanding OMS, SCADA and continuously evolved within the industry to adapt to market and grid requirements. 24/7 monitoring teams. This strength is further leveraged with a global team holding deep international experience to enhance Suzlon's value chain. S95 & S97
