The deal is for the Uckermark wind farm in Brandenburg. It is the third V112 contract for the wind turbine, and the second this week.
However, the order follows some well-publicised problems in testing with a V112 prototype.
Last week Vestas said the turbine suffered a setback in testing. According to reports, a 6-metre to 7-metre portion of a blade broke off the prototype yesterday.
After an investigation, Vestas said the failure was down to ‘human error’ as the blade was manually manufactured. The company said it had appointed an independent company to evaluate its findings.
Delivery is of the turbines is expected to be at the end of 2011. The contract also includes delivery, supply of spare parts and Vestas’ Scada turbine monitoring package.
Speaking about the deal, Enertrag president Jörg Müller said: "We consider the innovative new V112-3.0 MW to be the perfect turbine for our inland sites, where we aim for full load hours within the range of 3,000 per year.
"We have a long partnership with Vestas, based on our trust in Vestas’ technology, experience and knowledge in wind energy."
Yesterday’s Vestas announced a deal with German developer Prokon to supply 17 V112 turbines to a wind farm in Mecklenburg-Vorpommern, Germany. Delivery is scheduled for the end of 2011.
The biggest V112 deal came with the contract to supply 140 of the turbines for the Macarthur 420MW project in Australia. The development will be the largest in the southern hemisphere.
