Suzlon S95 2.1 MW receives type certification; Delivers 102% of estimated power curve
Pune: Suzlon Group, the worlds fifth largest wind turbine maker*, announced
completion of testing and certification of its S95 STV (Standard Temperature
Version) turbine in its 50 Hz and 60 Hz variants. The testing was carried out by
independent third party testing agencies, and the certification by Germanischer
Lloyd, a global leader in certification.
The S95, with a rotor diameter of 95 meters and tower heights of 80, 90 and 100
meters, is specially designed for medium wind speed sites (Class II wind regimes).
It is part of the S9X suite of turbines, which has already seen over 1,000 MW in
orders since its launch in April, 2011.
The S95, in testing and validation, delivered 102 percent of its estimated power
curve, translating to higher than projected power generation, and improved returns
for customers - an increase in energy yield of over 3 million kilowatt-hours over the
Speaking on the development, Mr. John OHalloran, President, Technology
Suzlon Energy Limited, said: This is a phenomenal achievement; it is incredibly
rare that a complex product like a wind turbine with over 2,000 parts and weighing
over 250 tonnes generates more power than was even projected. This increase is
mainly attributed to our new smart aerodynamic technology and efficient control
systems. We are pleased to report that the S9X suite is consistently delivering 97
percent plus uptime on all installations, over a period of more than 10 months now.
This result is a testament to our ability to build on our vast global operating
experience. We have continuously evolved our technology and products to deliver
ever improving returns to our customers.
Added Mr. Tulsi Tanti, Chairman Suzlon Group: We are pleased to present
these findings to the market. Our customers have already placed more than 1 GW of
orders with us for the S9X suite of turbines, and this result clearly underscores that
we have delivered a product that exceeds their demanding standards.
I firmly believe that technology is the key differentiator in our industry; and the key
to market leadership. Our focus has been to consistently lower the cost of wind
energy, and as a result we are today achieving parity with conventional sources like
coal and gas. At Suzlon Group, we have a wind turbine for every kind of wind site in
the world, and our focus remains to generate more energy from the same resources,
creating more profit for our customers and more green energy to power the global
The S9X suite builds on Suzlons long experience in the 2 MW space with its fleet of
over 2,000 S88 turbines translating to over 4,000 MW of power generating
capacity operating around the world. The S9X builds on the robust track record of
the S88 and was designed with exhaustive customer input to customize the product
and service offerings to meet the exact needs of customers and operators around the
