Vestas Launches New Multi-MW Turbines

At the HusumWIND 2003 trade fair in Germany, Danish wind turbine company Vestas will be launching its very latest turbines: the V90-1.8 MW, V90-2.0 MW, and V90-3.0 MW. All three models have been subjected to a period of in-depth testing and serial production of the turbines will start at the beginning of 2004.

Ringkøbing Denmark – September 24, 2003 [SolarAccess.com] “There is no doubt that our V90 turbines will contribute to improving the competitiveness of wind power and thus be a major step towards achieving our vision of making wind power one of the significant sources of energy in the world,” said Svend Sigaard, President and CEO of Vestas Wind Systems. According to Vestas, the V90-3.0 MW turbine, which features a new nacelle design, can present a range of solutions that sets new standards for wind turbine technology. “As transportation costs are closely linked to the total weight of the turbine, we have followed unconventional paths in our search for a lighter nacelle,” said Sigaard. “Our new design eliminates the need for a conventional main shaft thus appreciably lowering the weight of the nacelle.” The 44-meter blades of the V90-3.0 MW turbine are the longest Vestas has ever produced, and the company has introduced new materials into the blade construction. In a number of areas, light carbon fiber components have replaced those traditionally made of fiberglass. “This means that the 44-meter blades are lighter than their 39-meter predecessors,” said Sigaard. “At the same time, the new blades feature an advanced aerodynamic profile that helps to minimize the loads on the nacelle and the tower. Reduced weight means reduced loads which results in improved efficiency.” Combining the further development of the V80-2.0 MW turbine with the new 44-meter blade designed for the V90-3.0 MW turbine has led to development of the two other new turbines in the V90 range, the V90-1.8 MW and the V90-2.0 MW. The launch of the 1.8 MW and 2.0 MW models complete Vestas’ new V90 range, allowing the company to supply the best possible turbines for any kind of wind regimes. According to Vestas, the V90-1.8 MW and V90-2.0 MW are particularly well-suited to areas with modest wind conditions and are primarily intended for the markets of Central and Southern Europe. “I am convinced that the market will respond very positively to these new turbine models, especially because all three meet the desire for an efficient way to more power,” said Sigaard.
