Proven technology for onshore wind projects: the Siemens Gamesa 5.X platform

The new Siemens Gamesa 5.X onshore platform has its roots in Siemens Gamesa technology, synonymous with innovation, know-how and reliability accredited through experience. The Siemens Gamesa 5.X platform incorporates proven technologies, minimizing risk and guaranteeing reliability for its two new product models: SG 6.6-155 and SG 6.6-170 wind turbines.

These include a doubly-fed generator and partial converter combination, a compact drive train design with a three-stage gearbox, and the use of components widely validated on our platforms. The result is a wind turbine design that gives optimum performance and LCoE.

Technological highlights

Reliable geared technology

Our onshore approach is focused on geared technology, in which we have extensive knowledge and expertise. The hallmarks of Siemens Gamesa turbines are: reliability, robustness and a modular, flexible design for optimum adaptation and maximization of production at any site and in all wind conditions.

OptimaFlex

Thanks to OptimaFlex technology, we go beyond the traditional off-the-shelf approach that results in products that are sub-optimal for many sites, and we deliver a uniquely tailored solution that is perfect for our customers’ specific needs. Optimized site design combined with a customizable product platform, based on flexible power rating, site specific towers and optimized BoP solutions, allow Siemens Gamesa to deliver reduced LCoE by increasing AEP while optimizing cost.

DinoTails® Next Generation

As an aerodynamic blade add-on, DinoTails® Next Generation reduces the sound power levels by using a serrated trailing edge mounted at the blade and adding finer combs in between the teeth. This world-leading noise reduction technology enables us to create value for our customers by maximizing AEP and reducing the LCoE in sites with noise constraints.
