The picture looks strange. You can see a ship through the turbine blade. That seems to be because ifisicence took a promotional picture with lettering and leaf decoration from here [1] and "cleaned it up" with some photo tool.
General Electric and Vestas both have 14 megawatt wind turbine prototypes in operation. This seems to be a prototype deployed in a large installation. It's not in the catalog yet.[2] Mingyang has been delivering some 12 megawatt units. Two years ago they announced a similar model with slightly shorter blades.[3]
