History of Siemens Wind Power A/S started in 1980, when Danish irrigation system manufacturer Danregn diversified into the windturbine business. Its first wind turbines were machines with rotor diameters of around with generator powers of . In 1981, the wind activities were separated into newly established company Danregn Vindkraft A/S, established by Peter Stubkjær Sørensen and Egon Kristensen in

The company changed its name from Danregn Vindkraft to Bonus Energy in 1983, an easier name for the English speaking North American market. In 1991, eleven 450 kW Bonus turbines were installed in the Vindeby Offshore Wind Farm, the first offshore wind farm in the world. The company sourced its first blades from Viborg based company Økær Vind Energi. Later it sourced blades from

), and announced an additional facility near Paull, East Riding of Yorkshire, east of Hull which would manufacture rotor blades for turbines. In 2014 the planned factory at Paull was abandoned, with all production to be concentrated at the Alexandra dock site. Revised plans for the site submitted April 2015 included only a blade manufacturing factory at the site with no nacelle production. In 2015 Siemens upgraded its 6 MW offshore design to a rated 7 MW power with a larger permanent magnet generator, and further to 8 MW in 2016. The first order for the 7 MW design was awarded in October 2015 for 47 turbines in the Walney 3 offshore. In early 2015 Siemens announced it had reached agreements to build 2 GW of wind turbines in

Merger

On 17 July 2016 Siemens and Gamesa announced their plan to merge their wind businesses, with the 59% stake of Siemens and the 41% stake of former Gamesa shareholders in the resulting company. Siemens paid €1 billion cash for its stake in Gamesa. The resultant company was headquartered in Spain, with an offshore operations headquartered in Hamburg, Germany and Vejle, Denmark. The combined business was the largest wind turbine manufacturer worldwide by installed capacity (~69 GW). The merger became effective on 3 April 2017.

Post-merger

In 2018, Siemens Gamesa won the wind turbine supply contract for the largest offshore wind farm in the world. It is a project of the Danish group Ørsted located in English waters, specifically 89 kilometers from the east of the coast, in which it will also carry out maintenance, and will install its SG 8.0-167 DD model turbines, with a total capacity of 1,386 MW. In the company's history, it is the largest project, ahead of Hornsea One (1,218 MW), also developed by Ørsted. In 2018, Taiwanese manufacturer Swancor began supplying wind turbine resin to Siemens Gamesa. In 2019, Siemens Gamesa agreed to purchase
