What our clients say about us
We have transitioned our Siegbach wind farm, which comprises three Nordex N100 Gamma turbines, from partial maintenance to a full maintenance contract with Deutsche Windtechnik AG – with very good results. In addition to the high level of commitment of the people at Deutsche Windtechnik, the flexible design of the contract was a deciding factor for us.
Moritz Moeller
Head of Renewable Energies Department at Mainova
Responsiveness, commitment and technical competence together with the right price were decisive factors for us when we chose the service provider for our wind farm in Gunnarby. We want to have a partner who treats our turbines like their own, offers constant service and proactive work and can ensure good maintenance as well as clean, competent work in an uncomplicated way. We hope that our cooperation with Deutsche Windtechnik will be characterised by respect, commitment and further development. These qualities are central to everything we do. The most important success factors for this agreement are clear communication and short response times.
Kaj Lamton
Operations Manager Wind Power at Wallenstam
At Leeward, we are committed to achieving the highest levels of safety, reliability and performance at our wind farms and value a strong partner like Deutsche Windtechnik to help us achieve these goals. We look forward to expanding our relationship and working together to lower the cost of energy by enhancing the performance of our assets.
Jason Allen
Chief Executive Officer, Leeward Renewable Energy
Deutsche Windtechnik is an independent service provider with experience in numerous different brands that has a good sense for the market price for different services. In addition to the price, the quality was the most important factor in our choice of service provider, and with Deutsche Windtechnik's openness and transparency in how it operates, we can say that Deutsche Windtechnik fulfils all of our requirements for a service provider.
Lars Jacobsson
Operations Manager, Rabbalshede Kraft AB
Rotor blade work was due to take place soon at our wind farm. Our cooperation has been very good in the past, and our trust in Deutsche Windtechnik continues to be rewarded. The work was done more quickly than expected and was more cost-effective. So it was a win for everyone.
