The London Array, a large-scale wind energy project that began construction in 2009, was switched on July 5. Siemens supplied the 175 wind turbines and the grid connection for London Array. Together with Dong Energy, Siemens will also be responsible for the service of the wind turbines through a long-term agreement.
The wind power plant owned, developed and built by a consortium consisting of Dong Energy, E.On and Masdar has a total capacity of 630 MW and will generate enough power to supply 500,000 British households with clean electricity. London Array will reduce annual carbon emissions by about 900,000 tons, which equals the emissions of 300,000 passenger cars.
The London Array offshore wind farm is located in the Thames estuary, about 20 kilometers off the Kent and Essex coast. Siemens supplied and installed the 175 wind turbines, each with a rotor diameter of 394 feet and a rating of 3.6 MW.
In addition, the company supplied the grid connection with one onshore and two offshore substations in the North Sea. The electricity generated by the wind turbines is bundled at sea and transported via high-voltage submarine cables to the coast. The wind farm will be operated and maintained from a purpose-built base at Ramsgate Port.
