Horns Rev (also known as Horns Reef) is a shallow area (glacial and sea deposits of sand〔(Horns Rev ), GEUS News nr 4, 2003. Retrieved March 2010.〕) in the eastern North Sea, about 15 km / 10 miles off the westernmost point of Denmark, Blåvands Huk. == Horns Rev 1 offshore wind farm == The reef contains the first large scale offshore wind farm in the world, Horns Rev 1 (160 MW from 2002),〔〔(Horns Revolution ), Modern Power Systems 5 October 2002. Retrieved 11 March 2010.〕 and is four times larger than the previous largest offshore wind farm in the world, the Middelgrunden at 40MW.〔Morgan, Colin. (Offshore Wind - State of the Art ) page 24 ''Garrad Hassan'', 20 October 2004. Retrieved: 19 November 2010.〕〔Larsen, Jens H. (The World´s largest off-shore windfarm, Middelgrunden 40MW ) ''Copenhagen Environment and Energy Office (CEEO)'', 2001. Retrieved: 19 November 2010.〕 At Horns Rev the Danish Energy company Elsam (now DONG Energy) built the first offshore wind farm in the North Sea. A total of 80 Vestas V80-2.0 MW units, capable of producing 160 MW, were installed by the Danish offshore wind farms services provider A2SEA in 2002 with the last turbine coming into operation on 11 December 2002. It receives a guaranteed price of 45.3 øre/kWh for the first 42,000 hours, paid by electricity consumers.〔"(Fremskrivning af PSO-udgifter )" page 4. ''Danish Energy Agency'', 19 May 2014. Accessed: 17 January 2015.〕 Since 2005, the wind farm has been owned and operated by Vattenfall. It cost DKK2bn.〔(【引用サイトリンク】url=http://www.power-technology.com/projects/hornsreefwind/ )〕 A radar has shown details of the wind patterns, improving local short-term forecasting.〔Pinson, Pierre. (Radar@Sea )〕〔(PossPOW: Possible Power of Offshore Wind power plants ) ''Technical University of Denmark''〕 Turbines are laid out as an oblique rectangle of 5 km x 3.8 km (8 horizontal and 10 vertical rows). The distance between turbines is 560 m in both directions. The main method of transport to the first wind park is an adapted Eurocopter EC-135 helicopter when winds are less than 19 m/s.〔http://ing.dk/artikel/horns-rev-laerte-vattenfall-lektien-173671〕 Hoisting the workers to and from a small platform on each turbine allows access to the park regardless of sea conditions which would otherwise prevent sailing in the area for a large part of the year. Vattenfall can change a gearbox in a day, and the farm has an availability of 96-97%. Two turbines are burnt out, and are uneconomic to replace with less than 10 years left.〔 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「Horns Rev」の詳細全文を読む スポンサード リンク
