A Fresh Wind for Siemens
The Siemens Energy Sector and Dong Energy signed an agreement for the supply of up to 500 offshore wind turbines on 6 March 2009. “The agreement with Dong Energy is one of the biggest orders in the history of Siemens,” said René Umlauft, CEO of the Renewable Energy Division of Siemens Energy. Anders Eldrup, CEO of Dong Energy, said that the agreement was the largest single offshore wind turbine supply agreement ever concluded, adding that Dong Energy had built approximately half of all offshore wind farms worldwide in operation today.
The wind turbines, which Siemens will deliver under the supply agreement, have a capacity of 3.6 megawatts, like those in operation at Dong Energy’s Burbo Banks offshore wind farm in Great Britain. These wind turbines are also being installed by Siemens at Dong Energy’s Gunfleet Sands I+II project. Wind turbines with a total capacity of up to 1,800 megawatts are planned for future Dong Energy offshore projects in Northern Europe.
In 1991 the two companies Siemens and Dong Energy constructed the world’s first offshore wind farm at Vindeby in Denmark and have since then worked together on many offshore projects including, for example, Middelgrunden near Copenhagen (Denmark), Nysted in Southern Denmark, Burbo Bank in Liverpool Bay (UK) and the soon to be installed Gunfleet Sands I+II (UK) and Horns Rev 2 (Denmark).

This is the strongest machine built in series for offshore parks, and thus for the use on the high seas. With Burbo wind farm Siemens installed the first offshore park with 3.6 megawatt turbines and a total capacity of 90 megawatts – in just one and a half months. Since the end of 2007 the wind farm has been supplying more than 80,000 households with clean power.
