New technologies ensure demand for wind generation remains high
Demand for wind generators remains high, particularly as new technologies can be optimised for lower-wind situations. Sean Ottewell reports.
La demanda de los generadores eólicos permanece alta, especialmente a medida que las nuevas tecnologías puedan optimizarse en situaciones con poco viento. Informa Sean Ottewell.
Die Nachfrage nach Windkraftanlagen bleibt hoch, insbesondere da neue Technologien für Verhältnisse mit Schwachwind optimiert werden können. Sean Ottewell berichtet.

n February, Alstom Renewable Power signed a memorandum of understanding with leading Brazilian wind power provider Renova Energia to supply, operate and maintain around 440 onshore wind
turbines in Brazil worth in excess of €1 billion. Ranging from 2.7-3MW each, these turbines
will represent a minimum of 1200MW new wind power generation capacity. Tey will equip Renova’s wind farms in the state of Bahia and will be delivered from 2015 onwards, over an estimated period of three to four years. Alstom’s ECO 100 3MW onshore wind turbine range was selected as one of the most proven machines on the market, with turbines running since 2008. It offers high yield and
leading efficiency across all wind classes, with its rotor diameter from 100-122 metres. Tis allows developers to select the best rotor for every position. Te combination of two or even three models of the range (ECO 100, 110, or 122) within the same wind site optimises the capacity factor of a project while reducing the balance-of- plant cost. Renova Energia carried out a thorough
process for the selection of the manufacturer, using ‘clean sheet’ cost assessment model and comparative analysis. “Alstom presented the best combination of price and technical performance, allowing for greater competitiveness in our projects, said Mathias Becker, ceo of Renova Energia. “Tis
