Siemens has received an order to supply 71 turbines for the 497MW Hohe See offshore wind farm to be located off the coast of German North Sea.

The order has been placed by Energie Baden-Württemberg (EnBW), which recently sold a stake of 49.9% in the Hohe See offshore wind farm to Canadian energy company Enbridge.

The total estimated cost of the wind farm is about €1.8bn.

Siemens will supply SWT-7.0-154 turbines, each with a capacity of 7MW. The nacelles will be manufactured at Siemens’ new facility in Cuxhaven by mid-2018 and will be shipped to the project harbour in early 2019.

Commissioning of the wind farm is expected to take place in the third quarter of 2019.

Electricity generated from the wind farm is expected to be about two billion kilowatt hours and this will be enough to power about 560,000 German households annually, while offsetting about 1.5 million tonnes of CO2.

Once the commissioning is complete, Siemens will also be offering service and maintenance of the turbines for a period of five years.

Connection to the grid will be established via the BorWin 3 high-voltage DC link and BorWin Gamma converter platform to be installed by Siemens for grid operator Tennet.

Siemens Wind Power Offshore CEO Michael Hannibal said: “We are happy to apply our full scope of engineering services at EnBW Hohe See offshore wind project.

“The extended scope makes this 497-megawatt wind power plant one of the largest projects that we have ever executed. Our customer thereby benefits from the proven experience of a multinational company along the entire value chain of large offshore wind projects.”
