Siemens Wind Power, (formerly Danregn Vindkraft A/S and Bonus Energy A/S) is a wind turbine manufacturer established in 1980 as Danregn Vindkraft. Bonus Energy was acquired by Siemens of Germany in 2004. The organisation became a separate division of Siemens in 2011, with headquarters established in Hamburg, Germany.
In 2015 Siemens Wind had a combined market share of 63% of European offshore wind turbines (nearly 75% in 2009 by capacity and number). In 2011, Siemens Wind Power had 6.3% share of the world wind turbine market, and was the second largest in 2014.
In 2016 Siemens Wind and Gamesa agreed a 59:41 merger of their wind businesses.
History of the company 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 10 m (33 ft) with generator powers of 20 to 30 kW (27 to 40 hp). In 1981 the wind activities were separated into newly established company Danregn Vindkraft A/S, established by Peter Stubkjær Sørensen and Egon Kristensen in Brande, Denmark, with a capital of 300,000 kroner; the company's product was a 55 kW (74 hp), 15 m (49 ft) blade diameter turbine.
Between 1982 and 1987 the company exported wind turbines to the USA in collaboration with Difko AS, in response to a wind farm building boom promoted by government subsidies; 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 (Denmark), 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 LM Wind Power. In the late 1990s Bonus began to develop its own blades, beginning production in the early 2000s in Aalborg.
Bonus AS was sold to Siemens in 2004 for an undisclosed amount, but before the sale the value was assessed to be somewhere between DKK 1.5 (USD 240 million) and 2.5 billion (USD 400 million). The sales and project management headquarters moved to Hamburg, Germany in May 2009.
