GE Wind Energy
Summary
GE Wind Energy is a branch of GE Renewable Energy, a subsidiary of General Electric. The company manufactures and sells wind turbines to the international market. In 2018, GE was the fourth largest wind turbine manufacturer in the world.
The entity was created as developer (not manufacturer) Zond in 1980 by James G.P. Dehlsen, who also formed Clipper Windpower in 2001. Enron acquired Zond and the German manufacturer Tacke Windtechnik in 1997.
In 2002, while gas turbine sales were declining, GE acquired the Enron Wind, the only surviving US manufacturer of large wind turbines at the time, during the bankruptcy proceedings of its parent, Enron. GE increased engineering and support for the Wind Division and doubled its annual sales to $1.2B in 2003.
By acquiring Zond, GE gained a very important patent for variable-speed systems (), which had a major impact on the North American market. Enron had continued production of the 1 MW and 1.5 MW wind turbines of Tacke Windtechnik and GE has expanded production in Germany.
GE acquired ScanWind in 2009, and in 2011 Wind Tower Systems LLC, a manufacturer of space frame wind turbine towers.
After the acquisition of Alstom's energy generating assets (2015) GE's wind portfolio was expanded to include the 6-megawatt 'Haliade' offshore turbine (at that time one of the world's most powerful turbines) from Alstom Wind. This became GE Wind (offshore). The same year, GE added Blade Dynamics Ltd., a designer and manufacturer of modular wind turbine blades with principal facilities on the Isle of Wight and in Southampton.
GE acquired LM Wind Power from Doughty Hanson & Co for an enterprise value of €1.5 billion in April 2017.
The GE platform began development with the creation of the 1.5-megawatt series of wind turbines that were developed with the cooperation of the United States Department of Energy. It consisted of three fibreglass blades attached to a horizontal axis hub. The hub is connected to the main shaft that turns a multi-stage system of gears.
