Siemens to provide 175 wind turbines for the London Array

Siemens Energy will supply 175 SWT-3.6-107 turbines to the London Array offshore wind project, which is owned by DONG Energy, E.ON and Masdar. Upon completion, the London Array project will be the largest offshore wind farm in the world with a capacity of 630 megawatts (MW). There is also an option to further expand the wind farm up to 1,000 MW in the future.

London Array is set to become the first 1-Gigawatt offshore wind farm, supplying enough power for approximately 750,000 homes – or a quarter of Greater London homes - and displace 1.9 million tonnes of CO2 emissions per year.

The wind farm will be located approximately 20 km off the coast of Kent and Essex in the Outer Thames Estuary. The project forms part of the UK's second round group of offshore projects. The wind turbines that Siemens will deliver under the supply agreement, which Siemens has signed with DONG Energy, have a capacity of 3.6 MW each.

The Siemens scope of supply includes delivery, installation and commissioning of the 175 wind turbines, including a five-year service agreement, which will see the company being responsible for servicing the offshore farm to ensure the turbines keep running effectively. The turbines will be produced in Denmark and are expected to be shipped to the site for installation in 2011 and 2012. The turbines will be installed in water depths of up to 23 meters and the site has an average wind speed of 9.2 meters per second. The wind turbine foundations and the grid connection are expected to be completed in 2011.
