But the developers have now awarded the service contract to Deutsche Windtechnik, which will maintain the 32 Senvion 6.2M152 turbines, which will operate in 6.3MW power optimised mode.
Rival manufacturer Siemens Gamesa is in advanced negotiations to takeover some of Senvion's onshore European assets, while other parts of the embattled German firm are also expected to be sold off imminently.
Deutsche Windtechnik's main tasks will include guaranteeing the turbines’ availability, eliminating remote faults, managing spare parts, and providing logistical services from Borkum or Emden, Germany.
The independent service provider’s board director Matthias Brandt explained that the company was awarded the contract due to its "extensive experience" in maintaining Senvion turbines. It also maintains Senvion turbines at the 62MW Alpha Ventus project and the 200MW Trianel Borkum Windpark I.
Trianel Borkum Windpark II is expected online by the end of the year. It is a 203MW extension of the 200MW wind farm with the same name, which was commissioned in 2015.
They were both approved under Germany's old feed-in tariff scheme prior to the start of the country's auction regime.
The site's are owned by the Stadtwerke-Kooperation Trianel (37.99%) — a consortium of municipal energy companies — utility EWE AG (37.5%) and a joint venture of the City of Zurich Electricity Company and Swiss investors Fontavis AG (24.51%).
