DWT has been awarded a service maintenance contract for the Mynydd Clogau wind farm in Powys, Wales. The contract, effective 17 April 2026, marks the successful transition of 17 V52 850 kW turbines to DWT's independent multi-brand full-service portfolio.
Engineering for the long haul: what this means for Mynydd Clogau
With 20 years under their belts, Mynydd Clogau’s V52s are now entering a phase in which parts sourcing is becoming progressively more complex and costly and where parts obsolescence will increasingly require engineering solutions rather than off-the-shelf replacements. Having seen DWT’s engineering capabilities demonstrated over their seven-year partnership, Nadara had the confidence to turn to a proven partner when it was time to take this legacy fleet forward.
DWT addresses this challenge through its group-wide extensive engineering departments. Rather than replacing failed components with costly new parts, DWT operates a dedicated repair-and-refurbishment loop: components are recovered from the field, fully inspected and restored, and returned to service in tested condition. The cost savings compared to new OEM procurement are significant, and for Mynydd Clogau, this translates directly into lower operational expenditure and minimised downtimes.
Where parts reach end-of-life with no available replacement — a growing challenge across the industry’s ageing turbine fleet — DWT’s engineering team goes further, developing in-house-engineered alternatives to meet or exceed the original specification. This capability to resolve obsolescence without OEM dependency gives Nadara long-term assurance that a hard-to-source or unavailable part will not become an availability problem for the wind farm.
A trusted partner across the Nadara UK portfolio
The Mynydd Clogau contract is the latest chapter in a longstanding partnership between DWT and Nadara, which now spans more than 7 years. DWT currently provides service and maintenance across 16 Nadara wind farms in the United Kingdom, covering 297 turbines and a combined installed capacity of 303.25 MW, including Mynydd Clogau.
In their own words
“We are pleased to be strengthening our strategic partnership with DWT as they take on the service and maintenance of our Mynydd Clogau wind farm, marking the successful transition from a 20-year agreement with Vestas on our V52 850kW turbines. With over 14MW of installed capacity, this site remains an important part of our portfolio, and ensuring its continued safe, efficient, and high-performing operation is critical. DWT’s technical capability, flexibility, and collaborative approach give us confidence in their ability to support the asset through its next phase of operation, and we look forward to building on this partnership to deliver long-term value.”
— John Morris, Head of Asset Management, UK Portfolio, Nadara
Nadara's continued trust in DWT reflects a clear track record: local engineering teams with deep familiarity of multi-brand turbine platforms, regional warehousing and supply chain infrastructure that supports rapid response, and a collaborative working relationship built on consistent delivery. DWT's independence from any single turbine manufacturer means its engineers bring objectivity, flexibility, and broad technical experience to every site.
