Plans for the 497 MW Hohe See offshore wind farm in Europe’s North Sea are underway this week, with owner EnBW announcing its final investment decision and contractors identified.

Canadian energy infrastructure group Enbridge has acquired a 49.9 per cent stake in the €1.8bn ($1.9bn) project and the two companies are set to jointly build the windfarm, while EnBW will handle its operation and maintenance.

Located around 90 km north of the German island of Borkum, the 42 square km windfarm represents Germany’s largest offshore wind project to date and is planned to power around 560,000 households.

Siemens has been tapped to supply 71 of its 7 MW turbines plus foundations. The company said the contract represents the first time it will provide complete offshore wind power plant solutions including the foundations, the design of which it has been working on since last year.

The result was the development of a large monopile design with a length of up to 80 metres and a weight of up to 1500 tonnes, Siemens said.

Dutch subsea cable firm VBMS will provide the cabling under a contract which includes supply, installation and burial as well as termination and testing of 79 33 kV inter-array cables. A consortium consisting of Engie Fabricom, Iemants NV and CG Holdings Belgium will build the offshore substation.

Construction is scheduled to begin in early 2018 and the project is expected to come online the following year.
