Largest rotor in the 2 MW to 3 MW turbine segment delivers around 25%
increased wind farm yield
ZARAGOZA, Spain, Sept. 28, 2011 /CNW Telbec/ - Alstom announces the
launch of the ECO 122 - a 2.7MW onshore wind turbine that combines high
power and high capacity factor1 to boost energy yield in low wind regions worldwide.
The ECO 122's leading efficiency and high yield set a new benchmark for
low wind sites. At a wind speed of 7.5 m/s the turbine delivers a net
wind farm capacity factor of up to 42%, equivalent to 3,600 full-load
hours each year. Its 122-metre rotor diameter and swept area of 11,700
m2 - the largest in the 2 MW to 3 MW turbine segment - maximise the
harvest of energy and the return on investment to create new business
opportunities for customers from low wind sites.
Alfonso Faubel, Senior Vice President of Alstom's wind business, said: "Research and innovation are at the heart of our business. With the ECO
122 and other turbines in our ECO 100 platform, we're leading the
development of the new generation of high power, high-efficiency
turbines to increase value for our customers. Longer blades capture
more power more effectively, and with its swept area much larger than
current generation machines, the ECO 122 has set a new standard for low
wind sites around the globe."
The ECO 122 produces about 25% increased wind farm yield on a given
piece of land compared with today's 1.5 - 2 MW turbines, and fewer
turbines need to be installed. As an example, on a typical low wind
site, six current generation 1.5 - 2 MW turbines will produce around 40
GWh/year2, compared with more than 50 GWh/year with only five ECO 122 turbines.
This yield advantage also means significant capital expenditure savings.
An ECO 122 powered wind farm can reduce balance of plant costs by
10-15%, compared with a farm using typical 1.5 - 2 MW machines, due to
fewer foundations, platforms and roads, and less cabling.
The ECO 122 is the latest evolution of Alstom's proven ECO 100 turbine
platform, and the result of more than 30 years of experience in wind
turbine design. The ECO 100 platform now has more than 350 MW installed
or under construction worldwide and over 200,000 cumulative operating
hours since 2008. All Alstom wind turbines are based upon the unique
and proven ALSTOM PURE TORQUE® rotor support concept that protects the
drive train from deflection loads, ensuring higher reliability and
lower maintenance costs.
The first ECO 122 will be installed in mid 2012 with first commercial
deliveries expected in early 2013.

About Alstom's Wind Business
Alstom designs, assembles and installs a range of onshore wind turbines
spanning 1.67 MW to 3 MW and is currently producing the Haliade 150-6MW
- the first new generation offshore turbine. The company has been at
the forefront of wind technology development for the last 30 years with
innovations such as the unique ALSTOM PURE TORQUE® rotor support
concept that protects the drive train from deflection loads. Alstom has
installed or is installing over 2200 wind turbines in more than 120
wind farms, corresponding to a total capacity of over 3000 MW.
1 Capacity Factor is an indicator of how much energy a wind turbine
produces in a particular location, over a year. Since wind speed is not
constant, a wind turbine's annual energy production is never as much as
its MW rating multiplied by total hours in a year. Capacity factor is
the ratio of the actual energy produced in a year, to the theoretical
maximum possible if the turbine is running full time at full power
2 GWh = Gigawatt Hour. 1 GWh = one thousand megawatt hours
