GE has introduced its new, five-legged space frame tower for multi-megawatt wind turbines. The company says the new product enables towers up to 139 meters to be built in locations that were once difficult to access.
‘The space frame tower helps our customers go taller in new locations, further enabling the growth of wind energy,’ says Cliff Harris, general manager of GE's renewable energy business in Europe. ‘This next innovation in wind turbine technology is a stepping stone toward towers taller than 150 meters in Europe."
GE is introducing the space frame tower with its new 2.75-120 wind turbine and has demonstrated it in a full-scale turbine at the company's prototype site in Tehachapi, Calif. The company explains that the lattice tower is assembled at wind farm locations and then wrapped in an architectural fabric to provide familiar solid structural aesthetics.
According to GE, the tower's five legs offer additional down-tower space, allowing for storage within the turbine and making it easier to perform maintenance, site organization and balance of plant. Furthermore, the company says the tower has a "maintenance-free" bolting system.
