Suzlon Group, India's largest renewable energy solutions provider, has designed and manufactured the country's longest wind turbine blade at its Padubidri Rotor Blade Unit in Karnataka's Udupi district.

The blade is 63 metres long and has been developed for the company's new S128 wind turbine family which has a rotor diameter of 128 metres, 1.5 times taller than the India Gate monument in Delhi.

The turbine blade uses carbon girder for improved strength; it provides the capability to utilise thinner aerodynamic profiles and provides higher lift with less drag. The blade is lighter and cost effective too.

"It has been our continuous endeavour to reduce the levelised cost of energy by leveraging technology. Our R&D efforts are focused on developing technologically advanced and innovative products. The new blade will offer higher aerodynamic performance and improved annual energy production (AEP) and will harness the optimal available wind resources," said J P Chalasani, Group CEO, Suzlon.

The new blade offers 33 per cent more swept area and is expected to deliver 32 per cent more energy generation compared to previous generation turbine blades.

"The SB 63 blade is the longest and most efficient aerodynamic blade Suzlon has ever produced. We have introduced carbon fiber in the new generation of blades. This simultaneously reduces the weight of the blade and allows us to design even more aggressive airfoils. This creates a win-win solution for our turbine and our clients," said Duncan Koerbel, Chief Technology Officer (CTO), Suzlon Energy.

These rotor blades will be transported using an innovative two-fold transport system, which will use a specialised 'Adapter Trailer' for the first time in India.
