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 2009 it had a market share of nearly 75% of European offshore wind turbines 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.〔Badstue Pedersen, Maria Berg. "(BTM: Vestas stadig nummer et )" ''Energy Supply'', 30 March 2015.〕 ==History== 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 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 Brande, Denmark, with a capital of 300,000 kroner; the company's product was a , 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 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.〔Sources: * *〕 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).〔(Wind turbine concern Bonus Energy is up for sale ) ''Ministry of Foreign Affairs (Denmark)'', 25 June 2004. Retrieved: 18 October 2010.〕 The sales and project management headquarters moved to Hamburg, Germany in May 2009. Between 2004 and 2011, Siemens grew wind power from 0.5% to 5% of the combined Siemens turnover, with employees growing from 800 to 7,800, of which 5,200 are in Denmark, and 1,000 in Germany.〔 The growth included the expansion of production, warehousing and offices at its Brande site in 2005/6; acquisition in 2006 of a former LM Glasfiber wind turbine blade factory in Engesvang, Denmark; construction of a blade factory in Fort Madison, Iowa, USA in 2007;〔 a hub factory in Ølgod began production in 2008; and a nacelle manufacturing plant was established in Hutchinson, Kansas, USA between 2009 and 2010, opening in December 2010.〔Sources: * *〕 Additionally Bonus Energy sales and service partner company ''AN Windenergie GmbH'' in Bremen (Germany) was acquired in 2005.〔 In mid-2008 the company began testing of development prototypes of direct drive wind turbines; units based on the geared SWT-3.6-107 were installed in 2008 with a permanent magnet generator directly replacing the gearbox and alternator; Successful tests led to development of a new production design by 2009.〔 A prototype of the new direct drive design, an IEC 61400 wind class IA, 3MW machine (SWT 3.0-101 DD) was installed near Brande, Denmark in 2009. The 3MW design was launched as a product in April 2010 and significantly reduced complexity (half the components)〔 and lower nacelle weight than earlier 2.3MW designs. A 2.3MW version for lower wind speeds (SWT-2.3-113) was launched in 2011. In 2010 Siemens Wind Power acquired 49% of A2SEA (an offshore wind farm installation company) from DONG Energy for a price of DKK 860m.〔 〕 A factory established by Siemens Wind Power Blades (Shanghai) Co., Ltd. (SWPB) in Linggang near the Yangshan Deep Water Port began production in 2010.〔Sources: * *〕 Additionally in December 2010 Siemens announced it would install a blade factory at an existing unused facility in Tillsonburg, Ontario, Canada. In early 2011 Siemens and ABP announced the development of a £210 million turbine assembly plant, and dock development at Alexandra Dock, in Kingston upon Hull, UK. In 2011 Siemens' wind power operations were split into a separate division, 'Wind Power'; with its other renewable energy activities place into a 'Solar & Hydro' division, the divisions headquarters were established in Hamburg on 1 October 2011, the European offshore wind headquarters remained in Brande, Denmark. In July 2012, the company agreed to supply Dong Energy with 300 direct drive, 75m blade, 6 MW SWT-6.0-154 turbines for the English offshore market from 2014. Two turbines are to be installed for testing at the Gunfleet Sands offshore wind farm. The value of the contract was estimated at over £2 billion. In September 2012 Siemens Wind announced the lay off of 615 of a workforce of around 1650 workers in the United States, citing reduced demand for wind turbines due to uncertainty concerning future tax break incentives in the USA for wind power. In March 2014 Siemens and Associated British Ports (ABP) finalised the 2011 MOU to build a turbine factory in Hull, UK ('Green Port Hull'), 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 early 2015 Siemens announced it had reached agreements to build 2GW of wind turbines in Egypt, and to construct a blade factory in that country, as part of a larger power generation agreement. The €8 billion, 16.4GW energy development deal was signed in June 2015, including a ~1000 worker blade factory in Ain Soukhna and 12 wind farms (600 turbine, 2GW) in the Gulf of Suez and west Nile areas of Egypt. In August 2015 Siemens announced it was to construct a new nacelle manufacturing plant at Cuxhaven, Germany, an investment of £200 million. The plant was expected to become operational mid 2017, and employ 1000 people. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Siemens Wind Power」の詳細全文を読む スポンサード リンク
