Spanish turbine manufacturer Gamesa showcased its new wind turbine, the G136-4.5 MW Class III, which has a 136 metre rotor diameter and a 120 metre tower, at the 2011 Hanover trade fair this week.
The new turbine has the same design standards as the G128-4.5 MW Class IIA and a modular design making it as easy to transport and assemble as a 2 MW turbine. But its larger turbine increases its annual energy output by 8% compared with the G128-4.5 MW at low-wind sites.
"The G136-4.5 MM, now commercially available for installation in 2012, benefits from the exhaustive validation and testing programme conducted on the G10X-4.5 MW platform," said Javier Perea, Gamesa sales and projects general manager.
Technology giant GE, meanwhile, has introduced taller towers – over 130 metre – for its onshore wind turbine range to increase annual energy production and reduce the impact from turbulence.
The taller towers will initially be available for GE’s 2.5 MW turbines.
"With taller towers, more sites become attractive wind farm locations," said Stephan Ritter, general manager of GE Renewable Energy Europe. "The increased height also offers more customer value through higher winds and a reduction in the impact of turbulence resulting in higher annual energy production."
GE says it will target Germany, Scandinavia, Poland, Romania and Canada as the first key markets for the new taller towers.
