GE has recently announced a wind farm contract with German project developer Energiekontor AG for four wind power generating projects comprised of 41 2.75-103 wind turbines. Using a proprietary 50.2-meter blade with a proven aerodynamic shape, GE’s 2.75-103 wind turbine provides a larger blade swept area giving wind developers greater energy capture and improved project economics.
The new 2.75-103 wind turbine generator features an improved electrical system and has been fitted with 50.2-meter rotor blades that incorporate GE’s own design. Compared to the 2.5-100 model, the blades used on the new unit are capable of increasing the annual energy output by more than 9 percent at a wind speed of 7.5 m/s.
More energy, low noise emissions
The turbines will feature a 98.3-meter-high tower and a rotor diameter of 103 meters to capture more energy. The new units will boost GE’s contribution to clean and efficient energy production by generating some 250 million KWH of electricity a year—enough to supply more than 70,000 German households.
GE expects to commission seven turbines in 2013 in North Rhine-Wesphalia and 34 turbines in 2013 in the Cuxhaven area. All 41 wind turbines will be manufactured in Salzbergen in Lower Saxony.
Peter Szabo, Energiekontor’s managing director said, “GE is meeting the project’s strict noise control regulation requirements by using optimized trailing-edge serrations on its 2.75-103 range wind turbines. The technical design of these high-performance wind generators with their low noise emission levels is one of the main reasons we have chosen GE as our project partner.”
