Trianel Windkraftwerk Borkum II GmbH & Co. KG has issued a tender invitation for production, installation, and turnkey installation of the inner park cabling within an offshore wind farm in the EEZ.
The Trianel Windpark Borkum is the first offshore wind farm to have been established under the direction of Trianel Windkraftwerk Borkum GmbH & Co. KG with the exclusive involvement of 33 municipal utilities and regional energy suppliers.
In mid-July 2015, Trianel had put 40 wind turbines with a capacity of 200 megawatts, which are located approximately 45 kilometres off the coast of the North Sea island of Borkum, into full operation. In October last year, the municipally anchored EWE AG from Oldenburg and the cooperation of municipal utilities Trianel from Aachen have sealed a joint venture for the collaborative development of the second expansion stage of the Trianel wind farm Borkum (TWB II) with 200 MW.
The second stage, with a further 40 turbines, should boost the capacity to supply about 200,000 households with eco-electricity.
