Gamesa Corporación Tecnológica (Spanish pronunciation: [gaˈmesa korpoɾaˈθjon teɣnoˈloxika]), formerly Grupo Auxiliar Metalúrgico, is a manufacturing company principally involved in the fabrication of wind turbines and the construction of wind farms.
It was formerly headquartered in Vitoria-Gasteiz, Spain, but subsequently moved in 2010 to Zamudio, Biscay in northern Spain. Gamesa develops, manages and sells wind farms, for which it also supplies wind turbines. It is the market leader in Spain and the fourth largest wind turbine manufacturer in the world (2011). 
The company has installed more than 10,000 MW of production in four continents, saving the equivalent of 51.9 millions of tons of carbon dioxide annually. It presently has over 20,000 MW of production in development in Europe, America and Asia and it is also involved in the construction and development of photovoltaic power stations.
Gamesa began operations in 1976 focused at that time on developing new technologies and applying them to emerging activities. These included robotics, microelectronics, aeronautics and the development of composite materials. In 1994, Gamesa Eólica was created as a subsidiary specializing in the manufacture of wind turbines. The company became involved in the development, construction and operations of wind farms in 1995 and completed its first wind farm the following year.
The Corporation was officially listed on the stock exchange on October 31, 2000 and joined the selective IBEX 35 on April 24, 2001.
Since 2006, the company has focused on technologies associated with sustainable energy, principally wind power. It has divested of its interests in aeronautics, which were sold off to form a new company known as Aernnova, and in services, which were sold off to form a new company known as Global Energy Services.
As part of the United Kingdom's move to expand its production of offshore wind energy production, Gamesa has committed to the expenditure of £133.7M on a production factory and other facilities in the UK, and will also move its offshore wind division headquarters to London.
Gamesa is listed on the Dow Jones Sustainability Index, the FTSE4Good Indexx which is concerned with corporate social responsibility on the KLD Global Climate 100 Index, and on the Global 100 Index of the 100 most sustainable companies in the world.
