GE renewable energy business has 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. There are currently two prototypes that have been in operation for 10 months, which were completed with Noble Environmental Power at Noble’s Clinton Wind Park in Clinton, New York. The technology upgrades GE 1.5-77 turbines to GE 1.5-91 turbines utilizing the entire existing blade asset
