Alstom signed a contract worth approx. EUR 120M with Tractebel Energia Brasil, the private power generator in Brazil, to supply 36 units of ECO 122 wind turbines to Trairí II project, a wind farm located in Ceará State, Northeast of Brazil. The commissioning of Trairí project is scheduled for mid-2016 and will generate 97.2MW. Alstom’s scope includes the supply of 36 units of ECO 122 wind turbines of 2.7MW each. In addition, Alstom will be in charge of the operation and maintenance of the wind farm for ten years.
For the first time, Alstom’s wind turbines will feature 119m concrete towers specifically designed for ECO 122, delivered in consortium with Freyssinet. This new tower will be made of precast concrete sections to be erected using a crane-less installation method based on proven hydraulic lifting techniques used in civil engineering. The nacelles of the wind turbines will be manufactured at Alstom’s plant in Bahia, taking full advantage of the company’s investments in the country.
The ECO 122 wind turbine has one of the biggest rotor diameters within the 2MW–3MW onshore turbine market segment. The ECO 100 platform now has more than 1000 MW installed or under construction worldwide and over 200,000 cumulative operating hours since 2008.
