Trairí II Project, Brazil: Wind Turbines Announced

While we all may be gripped in World Cup Fever in Brazil, wind project deals stop for no-one, not even the semi-finals.

It has just been announced that Alstom have signed a contract with Brazil’s largest private power generator, Tractebel Energia Brasil to supply 36 ECO 122 wind turbines tom the Trairí II project; a wind farm located in Ceará State, Northeast of Brazil. The contract is worth around 120 million Euros. The power generation totals 97.2MW derived from the 2.7MW ECO 122 Turbines.

Alstom will not only supply the turbines but be in charge of the operation and maintenance of the wind farm for ten years.

The ECO 122 wind turbines will have 119 metre concrete towers tailor-made for them. The tower will be composed of 11 concrete sections, with the lowest one, for the first block of the base, being 7.2 metres in diameter. We are told that a unique installation method will be used based on hydraulic lifting techniques used in civil engineering  to facilitate the assembly of the nacelle and tower at their final height.

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.

 

Yves Rannou, Senior Vice President of Alstom Wind business since 1 April this year (picture above), said: 

“The Trairí II project will be the first to use our new 119m towers that allow us to better harness wind resources regardless of wind characteristics. As such, it confirms the value our customers place on our investments in developing innovative wind turbines.”

Here are some facts about the ECO 122 wind turbine:

  • It has one of the biggest rotor diameters within the 2 MW to 3 MW onshore turbine market segment.
  • It combines high power and high capacity factor to boost energy yield in low wind regions- ideally suited to Brazilian wind conditions.
  • It is the latest evolution of Alstom’s proven ECO 100 turbine platform and the result of  30 plus years of experience in wind turbine design.
  • The ECO 100 platform now has more than 1000 MW installed or under construction across the globe and over 200,000 cumulative operating hours since 2008.
  • All Alstom wind turbines are based upon the unique and Alstom Pure Torque® rotor support concept that protects the drive train from deflection loads, ensuring higher reliability and lower maintenance costs.
