north sea windfarm borkum II green light offshore wind power


Construction of the Trianel Windpark Borkum II (TWB II) offshore windfarm in the German sector of the North Sea has been given the green light. The approval followed a final investment decision by 20 German and Swiss bankers.

The windfarm – formerly known as Borkum West II – is being built by Trianel Energie. Trianel is a joint venture owned by a number of German banks and electrical utilities, energy and gas providers, EWE AG and most recently a number of Swiss bankers. With a generating capacity of 203 megawatts (MW) it is equal to its predecessor Trianel West Borkum. The windfarm will be capable of generating enough power for roughly 200,000 homes. The project is expected to cost about €800 million.


Despite a slow start in the offshore wind sector, Germany has emerged as the strongest market for new projects in recent years. Europe’s offshore wind sector attracted a record-breaking €18.2 billion in 2016, with Germany leading the way. For 2016, installations were concentrated mainly on three countries: Germany (813 MW), the Netherlands (691 MW) and the UK (56 MW).

“By 2020, 6.5 gigawatts (GW) of offshore wind power are to be installed in the North Sea and Baltic Sea,” said Dr. Jörg Buddenberg, managing director of EWE. “With the Borkum II North Sea windfarm, municipal energy suppliers contribute to the development of the offshore sector.”


“The development of offshore wind is an important cornerstone for the success of the “Energiewende” [Germany’s energy transition],” added Sven Becker, chief executive officer (CEO) of Trianel GmbH.


Construction of the foundation structures (monopiles) for the Borkum II North Sea windfarm is planned for spring 2018. Commissioning is expected by the end of 2019. It will use 32 wind turbines, each with a rated output of about 6.3 MW. They will be installed in a water depth of 25 to 35 metres.
