Gamesa begins assembly of its G132­5.0 MW turbine

The blades of the G132­5.0 MW are reportedly the longest ever transported in Spain.

Gamesa (Zamudio, Vizcaya, Spain) has begun assembling its prototype G132­5.0 MW turbine, which will be equipped with one of the world's largest onshore rotors. The company has replaced the blades of the G128­5.0 MW, which has been in operation at the R&D facility in Alaiz (Navarre, Spain) for a year, with the G132­5.0 MW. Gamesa anticipates the turbine will begin to produce energy at the beginning of May.

This assembly job is quite the logistical challenge for Gamesa as the blades of the G132­5.0 MW are each 64.5 meters in length. In addition, the blades are the longest ever transported in Spain and were brought in a single piece from the factory in Aoiz to the R&D facility in Alaiz. The blades were transferred one at a time. 

Completion of the assembly work will begin the turbine validation and testing process with a goal to obtain type certification by the end of 2015, in order to accelerate its industrialization and commercialization.

In addition to the prototype's three blades, the company has made a fourth blade for testing at CENER, Spain's national renewable energy center. The static tests have already been completed and the fatigue tests (vertical and horizontal movements) are underway as these tests will take five months. All of these tests will also help to certify the blade to be installed in the G132­5.0 MW offshore model.

The prototype G132­5.0 MW, with a rotor diameter of 132 meters and a total height of 186 meters, generates 3% more power than the G128­5.0 MW and is capable of generating enough energy to supply 5,000 households for one year.
