Alstom upgrades onshore 3MW-range ECO 100 wind turbine platform
By Anthony Capkun
February 5, 2013 – To maximize available wind resources and further reduce wind power’s cost of energy, Alstom says it has upgraded its ECO 110 turbine—currently designed for medium (Class II-A) wind sites—to a medium and high winds (IEC Class II-A, and IS Class) turbine. The ECO 122 turbine—currently suitable for Class III sites—is being upgraded to a medium and low winds (IEC Class III-A, and II B Class) turbine. This upgrade, says Alstom, increases the net capacity factor to up to 48% for both turbines. With rotor diameters of 100 m, 110 m and 122 m, Alstom’s says its ECO 100 Platform wind turbines allow developers to select the best rotor location for each specific site. The combination of two or even three of these wind turbine models at the same wind farm has been named by Alstom as ‘Powerof3’; the company provides common spare parts, and standardized operation and maintenance procedures for the whole site.
