Dong Energy inaugurates Borkum Riffgrund 1 offshore wind farm in Germany

CTBR Staff Writer Published 12 October 2015

Dong Energy inaugurated its Borkum Riffgrund 1 offshore wind farm with an installed capacity of around 312MW in Germany.


Located 37km north of the German island Borkum and 54km from the German coast, the offshore wind farm features 78 units of Siemens SWT-3.6-120 wind turbines, each with a capacity of 3.6MW and a rotor diameter of 120m.

The clean electricity generated at the wind farm will be enough to power around 320,000 households.

The project will contribute to the German government's aim to install nearly 6.5GW of offshore wind energy by the end of this decade.

Dong Energy owns a 50% stake in the project, while the remainder 50% is jointly owned by the investors Kirkbi Invest and William Demant Invest.

Commenting on the development, Dong Energy board of directors chairman Thomas Thune Andersen said: "Borkum Riffgrund 1 is our first operational project in Germany and I'm very satisfied with the fact that we can now harvest the fruits of the investment we have put into this project.

"We are currently building another two offshore wind projects and have a number of other projects in our pipeline that will allow us to demonstrate the skills and competences we have gained and will allow us to continue to show the trust we have in the German offshore wind market."

Siemens will provide service and maintenance for the turbines at the project for an initial period of 10 years.

The Borkum Riffgrund 1 is Siemens' sixth offshore wind power plant to be inaugurated this year.

Siemens wind power and renewables division offshore CEO Michael Hannibal said: "Installation of our offshore projects in Europe is continuing at full speed.

"Siemens has already erected an offshore capacity of more than 5.8GW, with two gigawatts going online in the last fiscal year alone. We are making considerable progress in the industrialization of offshore wind power. Our goal is to drive power generating costs from offshore wind down below 10 euro-cents per kilowatt-hour by 2020."

Siemens inaugurated 288MW Dan Tysk, 576MW Gwynt y Môr, 210MW Westermost Rough, 288MW Butendiek and 288MW EnBW Baltic 2 offshore wind projects this year.
