Suzlon Group produces its first blade for the New S111 2.1 MW Turbine

  • Suzlon Group completes the design & production of its first blade for S111 2.1 MW Turbine: the SB54 Blade
  • Measuring 54.8 meters in length, the blade is ~80% longer than one wing of a Boeing 777
  • S111 can deliver a 20% increase in AEP(Annual Energy Production)
  • Group stays firm to its commitment “Driven by Technology & Innovation“

Pune, India: Suzlon Group, the world’s fifth largest* wind turbine maker, today announced that
it has successfully completed the production of its first blade for its best in class S111 2.1 MW
turbine. The S111 is a technologically advanced product of the S88 and S97 2.1 MW family. This
product has been specifically designed for Suzlon’s next generation 2.1 MW turbine and is
engineered to deliver a 20% increase in AEP (Annual Energy Production) at the same hub height
compared to Suzlon’s S97 wind turbine model.

The S111 is built on the proven reliability of the S88 and S95/97 2.1MW family that currently
has over 3100 turbines installed in fifteen different countries with over 68,000,000 operating
hours. The blade is designed to harness the optimal available wind resources and deliver higher
energy productivity, which in turn ensures higher ROI to customers. Suzlon turbines have been
setting industry benchmarks across the entire technology value chain by meeting new

Mr Laurens van der Sande, Project Manager, S111/SB54 blade said: “The first SB54 blade is
the longest and cleanest aerodynamic profile Suzlon has ever produced. This milestone has
been achieved due to an effective integration between the product design, production unit and
the tool design. The result is reflected in a shorter production timeline with a high yield

This innovative product is a testament of our unique integral design approach and our rigorous
New Product Development Stage Gate Process. We have surpassed our last three power curves
and expect the S111 to follow the same suit”.

Mr Tulsi Tanti, Chairman – Suzlon Group, said: “We believe in offering optimal energy
solutions to our clients, which is why we continue to leverage on our technological edge and
create products that derive maximum energy yield. The S111/SB54 blade is based on previous
Suzlon designs with innovative and optimized improvements.

The turbine design makes it ideal for low wind sites in growth markets like the US and India. We
stand committed to offer new age products and best in class services that to deliver high
energy yields products.“

The first S111 turbine prototypes are being assembled and will be erected and tested later this
year in India and in the USA. Certification is expected in the first half of 2015.
