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 MasdarUpon 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

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 outlook for the offshore market is positive,“ said Wolfgang

Dehen, CEO of Siemens Energy Sector. Siemens is already installing wind

turbines this year at five offshore wind farms in Great Britain and

Denmark. “By improving the political framework, the UK government has

laid the foundation for the continued expansion and investment in

offshore wind energy. Projects are now more profitable and hence more

attractive for investors. In addition to the London Array offshore

project, Siemens expects that more offshore projects will be

commissioned in the near future,“ added Dehen. With an installed

offshore capacity of more than 600 MW and an order backlog totaling

more than 3,300 MW, Siemens is the leading supplier of wind turbines

for offshore applications.

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.
