Many participants in wind power technology
Wind power suppliers: There is a large community of manufacturers and developers whose scope of supply ranges from complete wind turbine systems to hardware and software components and to numerous auxiliary subsystems that make up a wind farm. See list, photos, links.
Electric power generation from wind energy is a relatively young but growing industry. In some parts of the world it has shown remarkable growth. Looking ahead, realities of market economics and political issues may not support the same continued growth—at least in some parts of the world.
This article updates the original one posted on CE’s Web site in August 2009. (Link to that and many related wind turbine articles below, including videos.)
The focus here is on direct-drive (DD) wind turbine technology that eliminates the gearbox from the drivetrain (see August 2011 CE article on DD wind turbines linked below).
The following is a selected listing of supplier companies to the multimegawatt (MW) wind turbine market. Only DD turbine offerings are listed, but all companies in the first table also make geared turbines, with the exception of Enercon GmbH. The list is not comprehensive—and does not include turbine erection or maintenance services.
