Suzlon Energy designs and manufactures India's longest wind turbine blade

Rotor blade measures 63 meters in length for new S128 series of wind turbine

Suzlon Group has designed and manufactured the country's longest wind turbine blade at its Padubidri Rotor Blade Unit. The advanced blade (SB 63) measures 63 meters in length and has been specifically developed for Suzlon's new S128 wind turbine family with a rotor diameter of 128 meters, 1.5 times taller than the India Gate monument in terms of height.

This blade has been engineered with a carbon girder which provides the capability to utilize thinner aerodynamic profiles and provides higher lift with less drag to contribute to the turbine's excellent performance in low wind sites. The blade also incorporates flat back technology at the root that minimizes drag and saves additional weight and cost. The S128 series offers ~33% more swept area (12,860 m2) and is expected to deliver ~32% more energy generation compared to the S111. With an increase in the swept area Suzlon's next generation turbine is well equipped to improve energy yield and support competitive tariff environment in India while protecting our customers return on investment.
