Wind Turbine Generator Rewind

Grannell Community Energy (GCE) owns and operates a refurbished Enercon E48 wind turbine in Ceridigion, Wales. When the turbine failed, they contacted Houghton International to identify the cause of the failure and carry our repairs to return the generator to service.


The wind turbine was transported to Houghton International’s dedicated large machine shop for repair. With our 40 tonne cranage and 13 metre working height capability, the facility could comfortably accommodate the repair of the 26 tonne generator.


Considering the age, condition and previous work carried out, the Houghton International team recommended a full rewind of both the rotor and stator to minimise the risk of further faults and extend the operational lifespan of the turbine.


The operation was the first of its kind to be completed at Houghton International, requiring the manufacture of bespoke frame and motorised jig for the winding of over 50 miles (75 km) of continuous copper wire.

As a community energy group, we have invested significant time, effort and funds into our wind turbine project so when it came to repairs it was particularly important to us to find a repairer that could offer the highest quality of service.

From our first contact with Houghton International, we were impressed by their professionalism, enthusiasm and support for the project. Not only did they have the facilities to accommodate a project of this size, but they also gave us full confidence in their experience and technical expertise.

Throughout the project we received excellent communication from Chris Robson and the project team, who were always on hand to answer any queries, even outside of office hours. This gave us and our stakeholders great reassurance from start to finish.

The support from Houghton International even after the generator left their facility has been excellent. We were able to come back to them with further questions during the installation, and we are reassured to know they are on hand in future for any spares or maintenance support needed.

Having recently reinstalled the generator, initial impressions are that it is generating exceedingly well and we are optimistic it will meet our most ambitious projections for power generation. As a result of the comprehensive and diligent work carried out, we effectively have a brand new turbine in operation and we have every confidence that it will meet its 20 year lifespan expectation.
