London Array

F2

London Array is an offshore wind farm off the east coast of England, which will be built in two phases. The planning was begun in 2001 and approved the project in November 2007. A total of up to 341 wind turbines are planned to be built over a period of four years and will have a total power of about one gigawatt.

The first stage with 175 wind turbines and a total capacity of 630 MW was completed in December 2012, the plant started up in April 2013. On 4 July 2013 London Array was officially opened as at the time the largest offshore wind farm in the world of Prime Minister David Cameron. The entire project should sein.Vorlage of 2016: Future / In 2 years

General

London Array will be the initially largest wind farm in the North Sea. The site is located in the outer mouth region of the Thames off the coast of the English counties of Kent and Essex and covers an area of ​​245 square kilometers in water depths of up to 23 meters. Project is being developed by the consortium of London Array Limited. Participants include the British subsidiary E.ON, Dong Energy and the Mubadala Development Company, which took over 2008 20 percent of the shares of E.ON. Participation was initially home to the Royal Dutch Shell energy companies, but withdrew in 2008. When completed annually to 3400 GWh of energy produced, which corresponds to the energy needs of 750,000 households.

Phase 1

The first stage with 175 wind turbines (WT ) and a total capacity of 630 MW, was completed in December 2012. The turbines were supplied by Siemens Wind Power. Were installed turbines of type SWT 3.6-120 3.6 MW rated power, the plants have a rotor diameter of 120 meters and a hub height of 87 meters. The total height of a wind turbine is 147 meters.

The monopile foundations of the wind turbines and two substation platforms built Bilfinger Berger together with the Danish partner Per Årslev. In the two substations of originating from the WEA stream of medium voltage (33 kV) is transformed to 150 kV and directed via submarine cable to a purpose-built substation in Cleve Hill, where connection is made to the 400 kV network. A total of 210 km 33 kV cable and 220 km 150 kV cables were laid.

The total investment amounted, according to the investors to 2.2 billion pounds, or about 2.5 billion euro.

Phase 2

The total cost after completion of Phase 2 with additional 240 megawatts are estimated at 3 billion pounds. Funding is secured additionally by the European Investment Bank. The British government is pursuing the goal of increasing the share of renewable energies in the electricity supply by 2015 to 15.4 percent.
