Designed and engineered to power customer aspirations

S9X: Making profitable and efficient wind energy accessible

As the high wind speed sites across the world become saturated the focus has shifted to providing efficient wind turbine

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.

Key inclusions in the S9X design are:

1. DFIG convertor featuring variable speed

2. Larger swept area with rotor diameters; 95 and 97 meters

3. 80-meter, 90-meter and 100-meter hub heights

The Suzlon Group

Suzlon is one of the leading wind turbine manufacturing groups in the world, with a presence in 32 countries on six

continents and over 17 GW of wind power installations.

Started in 1995 in India, the group is today a true multinational organization committed to sustainability.

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, wind

farm development, OMS and project management services.

Doubly Fed Induction Generation

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

prototype phase, the SEG Woodward’s CONCYCLE Power Convertor System has

continuously evolved within the industry to adapt to market and grid requirements.

STRONG product backed by proven performance, efficient processes, and a customer focused team, under the

umbrella of a global company with local reach.

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

inherent company culture of ongoing client interaction has allowed for transparent customer dialogue and specific input

regarding the S9X product development.

Suzlon's talent value chain truly optimizes wind farm operations. From the start, the knowledgeable, can-do sales team is by your side through the complex stages of a wind power project and is strongly supported by outstanding OMS, SCADA and 24/7 monitoring teams. This strength is further leveraged with a global team holding deep international experience to enhance Suzlon's value chain.

SMART enhancements, innovation and comprehensive design driven through the entire technology platform for

better reliability.

Suzlon turbines are smart throughout the entire technology value chain by wisely meeting industry standards that utilize

solid design, advanced engineering, and efficient production and distribution.

Smart S9X innovation and comprehensive design increases energy yield, improves serviceability and ease of maintenance

for this latest generation of wind turbine.

Smart features:

Generator: A compact and modular DFIG design allows ease of serviceability and meets the latest grid requirements for

smoother power plant connectivity that accommodates fluctuating utility demands.

Blades: Suzlon has consciously pursued two different blade designs for the S95 and S97 to operate on a wider wind speed

spectrum. Moreover, Suzlon is one of the few OEMs to own a blade testing facility that boasts GL certified static and dynamic

testing. Our blades are tested to exceed industry baseline by simulating total life cycle (1 million cycles) in the most extreme

on-site conditions. Tested like no other blade in the industry!

Tower: A variety of hub heights are also available due to customer demand, which include 80, 90, and 100m towers at 15%

less weight while still allowing higher power generation in low to medium wind speeds.

Improved $/kWh return on investment

Our systematic approach to the S9X platform, supported by customer feedback and the proven reliability of our

existing fleet, reduces the risks normally associated with the introduction of a new turbine. You can be assured of a

strong product and warranty, backed by smart comprehensive design and a safe company culture that will help you

gain a higher return on investment.

SAFE culture of the company is captured in all aspects: product, people, processes and documentation.

The S9X includes enhanced safety features that aim at making maintenance easier and more cost-effective. Nacelle access

doors and an extended beam crane to lower components to the ground make for improved workability with the option of

emergency hatch, should the need arise. An internal long-bended crane-rail system makes for convenient handing of parts

inside the nacelle.

All Suzlon technicians are trained in the work practice requirements that exceed regulatory standard. All employees are

expected to join together to make Suzlon a successful, accident-free and a healthy place to work. That's why we create the

leadership capability needed to support a safe company culture.

Long bended crane rail system inside nacelle makes for safe and convenient handling of parts
