More than 30 years experience in the onshore wind power business and more than 25 years in offshore: choosing proven technology means you choose reliability and sustainability. We help to maximize your return on investment while leading the industry in delivering a lower cost of energy for everyone – no matter what type of wind turbine you are looking for.
Every site faces particular challenges, which call for the right choice. For high-wind locations or offshore sites, you need a different turbine compared to the application on flat land or in low-wind areas. Differences in, for example, tower height, rotor size, and nominal output can turn a simple wind power plant into a profitable investment.
To meet various needs, we offer two different main technologies. Geared turbines take the classical approach to wind power. The proven combination of gearbox and generator is an evolutionary design for high-energy yield at both full and partial loads. The gearless direct drive turbines boast simplicity. Replacing the gearbox, the coupling, and the high-speed generator with a low-speed generator eliminates two-thirds of the conventional drive-train arrangement. We chose a permanent magnet generator, which leads to high efficiency even at low loads.
All our products are custom-built, exceptionally tried and tested, and made with your needs in mind. To make it easier for you to choose the right product, all Siemens wind turbines are categorized in four product platforms answering different needs regarding site and technology: onshore geared, onshore direct drive, offshore geared, and offshore direct drive turbines.
With rotor diameters optimized for all wind classes and a nominal power of 2.5 MW, the geared onshore turbines are the right choice for low to high wind conditions on land – no matter the climate conditions. They are especially tailored to match capacity-limited site conditions. With more than 8,500 turbines installed with a total capacity of 20 GW, this product family is our showpiece. Best practices and lessons learned were incorporated in the design of these turbines, leading to a constantly high and still improving fleet availability.
More than 11.8 GW sold – investors worldwide are convinced that Siemens Onshore Direct Drive turbines are the ideal solution for all wind classes, in any onshore environment. The latest generation of these turbines is more proof of how Siemens innovates with your needs in mind. Following the idea of “the simpler the better,” the high-performance direct drive generator with its simplified modular design enables faster time to market without compromising quality. Real-time Power Optimization allows a new level of flexibility – by letting the SICS controller work together with the generator to readjust performance depending on the ambient environment, for continuous returns. The result: the highest AEP output in their class. In addition, the compact and lightweight design of the nacelle as well as the outer rotor helps lower your transportation and installation costs and therefore supports the quick amortization of your onshore wind power investment.
Prior to the development of the direct drive, the geared offshore turbines were the most popular Siemens product for application at high sea – with good reason. These high-output workhorses have a world-class track record regarding reliability and the highest capacity factor in the industry. The popular SWT-3.6 family, the predecessor of today’s geared offshore turbines, has been installed more often than any other offshore wind turbine family worldwide - more than 1,600 units altogether, with the first prototype installed in 2004. Since then, a fully developed supply chain with off-the-shelf components and optimized installation and maintenance concepts has been established. This reliability makes your wind power projects sustainable and helps to keep your long-term investment safe and profitable.
Two turbines for two different IEC classes: the direct drive offshore turbines suit challenging sites at sea where superior performance is key. The technology has been deployed successfully in the field for years, with many core components already in place in turbines produced in large volumes. This fact facilitates bankability and gives you a more viable business model. The low-weight standard made possible by the lean construction offers significant cost benefits in terms of substructure requirements, shipping, installation, and service. And it makes the Siemens Offshore Direct Drive turbines the lightest weight per megawatt in the industry. The simple drivetrain with fewer moving parts strengthens turbine resilience in harsh offshore environments.
