Search Home Siemens About us Sustainable development Environmental portfolio Renewable energy sources These and many other solutions, such as components for biomass power plants, are part of the Siemens environmental portfolio. Onshore wind farms Onshore wind turbines are a key contribution to sustainable and green energy. The use of wind energy is one of the most reliable and dynamically growing methods of generation based on renewable sources. Siemens has thirty years of experience in this field and is one of the market leaders in onshore and offshore wind turbines, with a total of more than 9,000 onshore wind turbines installed worldwide (2010 figures). Greener wind farms, compared to fossil fuel power plants (coal and gas), help reduce carbon dioxide emissions by several million tons annually and have a total capacity of over 11,000 megawatts. The company continues to actively increase its capacity and develop new production sites. At the moment, the technology is actively used in Europe, America and Asia. For several years, Siemens wind turbines have set the standard in terms of reliability, which distinguishes both supporting structures and a relatively low maintenance mechanical system. Wind turbines can be used with different wind strengths. The rated capacity of power plants ranges from 2.3 MW at low and moderate wind speeds to 3.6 MW at high speeds. The average rotor diameter ranges between 80 and 120 meters. Made with high quality fiberglass and epoxy resin, the rotor blades are manufactured using our proprietary IntegralBlade® technology. Unlike conventional methods, no adhesive joints are used in this case. As a result, the one-piece blades are extremely reliable and allow you to extract the maximum amount of energy at any wind speed. An important element is gearless wind turbines: they have half the number of components than in gear-driven counterparts. The NetConverter® conversion system, a standard part of all Siemens wind solutions, allows the amount of power generated to be tailored to the grid. The power of onshore wind turbines is comparable to that of many fossil fuel power plants. In addition, improvements in the efficiency of turbines and generators have made onshore wind power an economically viable solution, even in regions with moderate wind strength. At the moment, the trend of replacing turbines of the previous generation with new, more powerful units has also been actively developed.
