Indian manufacturer Suzlon has produced the first 54.8-metre blade for its S111 2.1MW wind turbine.
The S111 evolved from the S88 and S97 2.1MW family and is engineered to deliver a 20% increase in annual energy production over the S97, the company said.
Project manager Laurens van der Sande 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 product.”
Suzlon Group chairman Tulsi Tanti added: “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 first S111 turbine prototypes are being assembled and will be erected and tested later this year in India and in the US. Certification is expected in the first half of 2015.
