The turbines will be split across two plants totalling 66.7MW in northern Poland, with delivery to commence next May and Siemens slated to commission the projects by late summer 2014. 

The German wind giant will stay on to maintain the projects for five years. 

With hub heights of 115 metres, and rotor blade diameters stretching to 108 metres, the turbines will be optimised for light- to medium-wind conditions.
