GE Successfully Proves Technology to Extend Wind Turbine Blades

May 6, 2014 (GE Water & Power)

“GE’s renewable energy business announced a technology demonstration of a 7-meter blade extension, taking GE wind turbines from a 77-meter rotor to a 91-meter rotor. The extension increases the swept area of the rotor by 40 percent and increases the energy production by more than 20 percent…[T]wo prototypes that have been in operation for 10 months…[at Noble Environmental Power’s] Clinton Wind Park in Clinton, New York…The technology upgrades GE 1.5-77 turbines to GE 1.5-91 turbines…[to] achieve significant increase in power output on their existing fleet…[GE] filed more than 16 patent applications and developed custom tooling for the extension installation…The extended blades have undergone testing beyond IEC requirements, including static strength tests that are standard for all GE-engineered blades and fatigue tests totaling more than 6 million cycles…” click here for more
