Deutsche Windtechnik secures maintenance contract for 56 Bonus A/S turbines

Another major order in the UK

Deutsche Windtechnik’s flexibility and consultative approach has secured it yet another contract for wind turbine maintenance in the UK: Starting from 1st April 2024, Deutsche Windtechnik has been responsible for the maintenance of 56 Bonus A/S 600 turbines at the Carno Wind Farm in Wales, now operated by Carno 1 LLP, for another 3.5 years.


Deutsche Windtechnik has enjoyed a successful and trusting partnership with the Carno Wind Farm for many years already. The full-scope maintenance contract (excluding major components) for the 56 Bonus A/S 600 turbines first came into effect in December 2017. In early 2024, the wind farm’s assets were taken over by Carno 1 LLP, directed by Sion Thomas.

High standard of service and exceptional availability

Sion Thomas, Director of Carno 1 LLP, said: “We look forward to continuing with the long-standing relationship Deutsche Windtechnik has with the Carno 1 wind farm. Deutsche Windtechnik has provided a high standard of service along with exceptional availability at the site for many years. The company was able to tailor the contract to our specific needs and DWT Business Development Team’s personal approach and commitment has been key to the successful negotiation of this new contract. I have no doubt, with the technical expertise and the many years of experience at the site, Deutsche Windtechnik will continue to provide the highest standard of service and availability at Carno 1.”

“It was a real pleasure getting to know Sion, to understand his business needs and work closely with him to find a mutually agreeable contract. We are looking forward to continuing our service and maintenance activities at Carno and maximising the potential return to Carno 1 LLP,” said Mark Dryden, Business Development Leader of Deutsche Windtechnik Ltd. With this renewed contract, Deutsche Windtechnik now has 224 AN Bonus and Bonus A/S wind turbines under contract in the UK alone. Worldwide, more than 600 of the 7,600 turbines under Deutsche Windtechnik maintenance contract were built by AN Bonus and Bonus A/S and more than two-thirds of them have full maintenance contracts.
