Paris, March 16, 2011 — Power generation equipment and services company Alstom, announced the upgrade of its 3 MW onshore ECO 100 platform.
Alstom's robust ECO 100 wind turbine platform, comprising the ECO 100 and ECO 110 turbines, is among the most proven multi-megawatt platforms in the marketplace with over 150,000 cumulative operating hours since 2008, and more than 300 MW installed or under construction. Both the ECO 100 and ECO 110 wind turbines are fully type certified.
To maximize available wind resources and further reduce wind power's cost of energy Alstom is upgrading both existing turbines of the platform and will also introduce a new machine to specifically address low wind speed sites across the globe.
The ECO 100 turbine, currently positioned for medium to high wind sites, is being upgraded to a high wind (IEC Class I-A) turbine that will have one of the leading capacity factors for turbines in this wind class.
The ECO 110 turbine, currently suitable for Class III sites, is being upgraded to a medium wind (IEC Class II-A) turbine. Its 110-meter rotor diameter is one of the largest available for class II sites and maximizes the energy yield of the turbine.
Longer blades capture more power more effectively. This means fewer turbines, and less land space, are required to generate the same amount of power. It can be thought of as more megawatts generated per square meter of land.
Hub heights of the platform are 75 m, 90 m, and 100 m, with higher towers planned for 2012. Both turbines are being offered now for deliveries from mid-2012.
Alstom will complete the range with a new high capacity factor low wind (IEC Class III-A) turbine, the ECO 11X, with a larger rotor diameter. The exact rotor diameter, in the range of 115-125m, will be released in the second half of 2011. At that time this turbine will be offered for deliveries starting in 2013
