Alstom launches the 3 MW ECO 110 wind turbine

Paris, June 9, 2010 — Alstom, a global leader in power generation, today announces the market introduction of its 3 MW ECO 110 wind turbine, designed to ensure the highest energy production on low to medium wind speed sites throughout Europe and worldwide.

The ECO 110 features a 110m-rotor diameter, one of the largest rotors available today for onshore applications — to capture even greater amounts of wind on a given site, maximizing the energy yield of the turbine.

Its 53 meter-long blades are designed to capture more power more effectively. This means fewer turbines and less land space are required to generate the same amount of renewable power.

Alstom‘s wind turbines are based upon the unique Alstom Pure Torque rotor support concept, which protects the gearbox and other drive train components from deflection loads.

The concept fully separates the gearbox from the supporting structure ensuring that only torque is transmitted through the shaft to the gearbox, and all deflection loads are transmitted directly to the tower.

While most conventional rotor support concepts tend to turn gearboxes into consumables, Alstom Pure Torque continuously delivers higher gearbox reliability, higher operational availability, and lower maintenance costs. Alstom is confident that the majority of its wind turbines could operate with their original gearbox for their whole design lifetime.

The ECO 110 has been designed to reduce its installation, operation and maintenance costs. Its modular design allows the use of industry standard transport and installation equipment.

The ergonomic design of its nacelle leaves room to perform easy maintenance of all components, and allows direct access from the nacelle to the hub.

The ECO 110 has also been designed to also minimize noise emission. By keeping the rotor speed below 13.7 rotations per minute, Alstom Wind’s innovation team has designed one of the most silent wind turbines available on the market.

ith its low noise emission, the ECO 110 is ready to contribute to the continuous and harmonious development of onshore wind power, particularly in Europe where this parameter is becoming critical.
