The new 2.75-103 wind turbine generator also sports an improved electrical system and has been fitted with 50.2-meter rotor blades of GE’s 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% at a wind speed of 7.5 m/s.
A major U.S. turbine OEM says it has a contract with a leading German project developer, Energiekontor AG, for four wind-power generating projects comprised of 41, 2.75 MW-103 wind turbines. Using a proprietary 50.2-m blade 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 units will boost GE’s contribution to clean and efficient energy production by generating some 250 million kWh of electricity a year
The 41 wind turbines will be manufactured in Salzbergen in Lower Saxony. The turbines will feature a 98.3-meter-high tower and a rotor diameter of 103 meters to capture more energy.
“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,” said Peter Szabo, Energiekontor’s managing director.
Energiekontor also signed a service agreement with GE including an extended spare parts and servicing contract for maintenance, routine inspections, and remote monitoring, along with manual resets to be undertaken by on-site service technicians and technical measures for troubleshooting and fault rectification.
