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
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.
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.
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.
The solutions we provide are driven by the benefits they deliver. This applies as much to our pursuit of absolute safety as to maximizing your return. Whether by inventing a new technology, evolving an existing product, or simply finding a smarter way of working, we strive to lower costs and raise returns on investments.
Our experts are on hand to help with any questions you have. Email us or login to our customer portal. Here you’ll be able to monitor configuration, production, and agreements for your wind power plants, and find relevant news from Siemens Gamesa Renewable Energy.
Operating in around 90 countries, Siemens Gamesa offers an extensive range of onshore wind turbine technologies to cover all wind classes and site conditions. By listening to our customers - and backed up by almost 40 years of experience - we know just what it takes to develop and manage a successful onshore project.
