Wind Power Companies
See also: Renewable energy industryWind turbine manufacturers design, test, manufacture, and assist with the operation and maintenance of wind turbines. Important choices facing them include turbine design (generator type, gearbox vs. gear-less, materials) and how much control to maintain over component supplies (internal vs. external). They must be concerned with maintaining their extensive fleets of operating turbines while at the same time developing newer and ever-larger models. The largest wind turbine manufacturers are based in Denmark, Germany, Spain, India, and USA.
Wind farm developers develop and sometimes own and operate wind farms. This involves purchasing or leasing land, installing meteorological equipment to quantify the wind resource, and securing transmission, power sales, turbine supply, construction, and financing agreements. Some small wind farm developers, lacking the "muscle" and financing necessary to secure major turbine supply contracts, will develop a project in order to "flip" it and sell to larger developers such as wind power managing owners.
Wind farm construction companies construct and sometimes assist with the operation and maintenance of wind farms.
Wind farm finance companies sell loans and other financial products to wind farm developers and wind turbine manufacturers. Most of these companies are large banks with experience in providing financing to other large industrial projects.
Wind power consulting companies offer consulting services to the wind power industry, including wind turbine design and certification, technical Due Diligence (or acting as the "Owner's engineer"), wind resource maps, wind resource assessments, wind power forecasting, and wind turbine power performance testing. Most of these companies maintain financial independence (no ownership stake) from wind farm projects in order to guarantee unbiased service to their clients.
Wind power research organizations provide research and development to the wind power industry. They are usually part of government agencies or universities and conduct research on aspects of wind power that are currently cost-prohibitive for the private industry to invest in.
Wind power managing owners are responsible for the operation and maintenance and administration of wind farms which they develop or acquire. All or part of these responsibilities may be subcontracted to third parties. Wind power managing owners, along with other financing parties and equity partners, typically sell the electricity generated from wind farms to public utilities under long-term Power Purchase Agreements (PPAs) where they receive a fixed price for the electricity.

Famous quotes containing the words wind, power and/or companies:
“I have hardly begun to live on Staten Island yet; but, like the man who, when forbidden to tread on English ground, carried Scottish ground in his boots, I carry Concord ground in my boots and in my hat,—and am I not made of Concord dust? I cannot realize that it is the roar of the sea I hear now, and not the wind in Walden woods. I find more of Concord, after all, in the prospect of the sea, beyond Sandy Hook, than in the fields and woods.”
—Henry David Thoreau (1817–1862)
“Ours is the old, old story of every uprising race or class or order. The work of elevation must be wrought by ourselves or not at all.”
—Frances Power Cobbe (1822–1904)
“Socialite women meet socialite men and mate and breed socialite children so that we can fund small opera companies and ballet troupes because there is no government subsidy.”
—Sugar Rautbord, U.S. socialite fund-raiser and self-described “trash” novelist. As quoted in The Great Divide, book 2, section 7, by Studs Terkel (1988)
