Gamesa started its business more than 40 years ago. The company's focus was on emerging activities such as robotics, aeronautics, and composite materials.
Years 1976 - 1980

1976: Gamesa is incorporated under the name of Grupo Auxiliar Metalúrgico, working on the management of industrial projects and technology for emerging businesses.

1980: Bonus Energy (later to be acquired by Siemens AG) was founded in Denmark, when the irrigation system manufacturer Danregn diversified into the wind turbine business.

One of the first modern wind turbines developed by Bonus Energy with an output of 95 kW. Almost 40 years later, onshore wind turbines produce over 40 times more electricity.
Years 1981 - 1990

1981: Bonus Energy builds its first 22 kW, 10 m blade diameter turbine (that was still generating power in 2016!).

1982: Bonus Energy delivers its first turbines to the American market.

1986: Gamesa commences activities in the aerospace sector.

1990: Iberdrola invests in Gamesa.

Vindeby was the world’s first offshore wind farm. The 11 Bonus 450 kW wind turbines were installed in 1991. After 25 years in operation the wind turbines were dismantled in 2017.
Years 1991 – 2000

1991: Bonus Energy builds the world's first offshore wind power plant at Vindeby, with a total capacity of 4.95 MW that can provide clean energy to around 2,000 households.

1993: Gamesa participates in the construction of a new aircraft for Embraer.

1994: Gamesa enters the wind energy sector.

1995: Gamesa installs its first wind farm in the hills of El Perdón in Spain.

1999: Installations by Gamesa reach the 1 GW mark.
