Dutch utility Eneco has signed a deal with Vestas that will see the latter continue to maintain the 60 2.0MW turbines that power the Princess Amalia offshore wind farm.
The ten-year agreement means that Vestas will be responsible for scheduled and unscheduled maintenance of the V80 machines, having successfully sold Eneco its Active Output Management (AOM) 5000 service.
The deal requires Vestas to ensure that "the turbines are fully operational when the wind is blowing", the turbine manufacturer explained. This "energy-based availability" commitment appears to guarantee Eneco an unspecified generation capacity.
Vestas has been maintaining the Princess Amalia turbines since they were installed. The wind farm has been fully operational since 2008.
Like its competitor Siemens, Vestas appears to be pursuing long-term service agreements with operators of wind farms powered by the machines it originally produced. Earlier this year, Siemens announced a ten-year deal to maintain turbines at the as-yet-unbuilt Butendiek wind farm.
