Gamesa in February said it was collaborating with U.S. defense contractor and shipbuilder Northrop Grumman to develop and supply European utility E.ON with an offshore prototype of its G11X-5.0 MW platform in 2012 (based on technology recently validated with the G10X-4.5 MW prototype). The Spanish firm is also developing another family of turbines, the G14X, anticipated to have a capacity of 6 to 7 MW. The pre-series for these larger turbines could be ready by 2014.
