Riffgat Offshore Wind Farm



公開日: 2013/05/05

This turnkey project involves the engineering, fabrication and offshore installation of a 33/155 kV offshore high-voltage substation to connect 30 pieces 3.6MW wind turbines with the German grid. With a total installed capacity of 108 megawatts (MW) the wind farm will supply approximately 100.000 German households with ecofriendly electricity.

Borkum Riffgat (also known as OWP Riffgat) is an offshore wind farm under construction 15 kilometres (9.3 mi) to the north-west of the German island of Borkum. The wind turbines are built across an area of 6 square kilometres (2.3 sq mi). It will consist of 30 turbines with a total capacity of 108 megawatt (MW), and is expected to generate enough electricity for 112,000 households. The project will entail investment of around €480 million (US$616 million) and construction work is likely to be completed in 2013.^[1][2]
Early 2011, the Dutch government stated that the wind farm was partly in Dutch territory and protested against the issuing of construction licenses by the German government.^[3]

Wind power in the European Union

In 2012, installed wind power capacity in the European Union totalled 105,000 megawatts (MW) - enough to supply 7% of the EU's electricity.^[1] 11,895 MW of wind power was installed in 2012 alone, representing 11.4% of new power capacity. The EU wind industry has had an average annual growth of 15.6% over the last 17 years (1995-2011).^[2]
A European Environment Agency report, entitled Europe's onshore and offshore wind energy potential confirms wind energy could power Europe many times over.^[3] The report highlights wind power’s potential in 2020 as three times greater than Europe’s expected electricity demand, rising to a factor of seven by 2030.^[4]
The EWEA estimates that 230 gigawatts (GW) of wind capacity will be installed in Europe by 2020, consisting of 190 GW onshore and 40 GW offshore. This would produce 14-17% of the EU's electricity, avoiding 333 million tonnes of CO2 per year and saving Europe €28 billion a year in avoided fuel costs.^[5][6]
In order to get a true picture of the 'CO2 cost saving' the calculations need to include the CO2 produced during manufacturing, installing and running the wind power units. And, that needs comparing with the CO2 costs of manufacturing, installing and running other electricity generators such as gas fired power stations etc. Lifetime CO2 costs should also be included as some sources of electricity generation may last longer than others. Finally, 'decommissioning CO2 costs' also need including. These may be quite high for some methods of electricity generation.
Research from a wide variety of sources in various European countries shows that support for wind power is consistently about 80 per cent among the general public.^[7]


Wind power in Germany describes wind power in Germany as part of energy in Germany and renewable energy in Germany. In 2011, the installed capacity of wind power in Germany was 29,075 megawatts (MW), with wind power producing about 8 percent of Germany’s total electrical power.^[12] According to EWEA in a normal wind year, installed wind capacity in Germany will meet 10.6% at end 2011 and 9.3% at end 2010 of the German electricity needs.^[13][14]
More than 21,607 wind turbines are located in the German federal area and the country has plans to build more wind turbines.^[15][16] As of 2011, Germany's federal government is working on a new plan for increasing renewable energy commercialization,^[17] with a particular focus on offshore wind farms.^[18]



List of offshore wind farms

http://en.wikipedia.org/wiki/List_of_Offshore_Wind_Farms

This page lists the top 25 offshore wind farms that are currently operational, rated by nameplate capacity. Also listed are the ten largest offshore wind farms which are currently under construction, the ten largest proposed, and offshore wind farms with notability other than size.
As of August 2013, the London Array in the United Kingdom is the largest offshore wind farm in the world at 630 MW, followed by the Greater Gabbard Wind Farm (504 MW), also in the UK. The Gwynt y Môr wind farm (576 MW) is the largest project currently under construction. The biggest producer of wind energy is the Greater Gabbard. In 2012 it produced 1,195 GigaWatt-hours (GWh). The second largest producer is Horns Rev 2 with 956 GWh produced in 2012. In terms of total production since introduction Horns Rev 1 remains the largest with 5,877 GWh produced since the park opened. Nysted 1, also in Denmark, is the second largest wind farm in the world in terms of total energy produced. Nysted 1 has produced 5,097 GWh since its start. Third is Horns Rev 2 with 2,959 GWh produced.^[1]
