The 10 Biggest Wind Turbines in the World

THE 10 BIGGEST WIND TURBINES IN THE WORLD As wind energy pushes to reduce the cost of energy, manufacturers have increasingly sought to increase the size of turbines. Economically, and environmentally, it makes good sense. The larger the turbine is, the greener the electricity. 1. ENERCON E126 7.5MW Enercon's E126 7.5MW, is purely designed for the onshore sector. The initial 6MW second-generation Enercon E-126, introduced in 2007, featured a concrete tower with a 135-metre hub height, and segmented steel-composite hybrid blades with a 127-metre rotor diameter. It also holds a 12-metre diameter generator. Around 34 E-126 units are operational. 2. REPOWER 6M SERIES The turbine aims to build on the success of its 5MW predecessor, one of the largest when launched in 2004 and used in a number of North Sea and Irish Sea projects such as the 150MW Ormonde wind farm. The turbine's rotor width is 126-metres while offshore the tower height is between 85-95 metres. SIEMENS 3. SIEMENS SWT-6.0 150 Siemens' 6MW offshore machine only exists as an onshore prototype, it is set to have the world's largest blade at 75-metres long. Siemens have got off to a good start with the turbine, signing a 1.8GW €2.9 billion deal with Dong Energy. The machine has a lot to live up to, as its predecessor the SWT 120 3.6 is generally regarded as the best turbine in the offshore sector. SINOVEL 华 锐 风 电 4. SL6000. SINOVEL SL6000 The turbine has a 128 metre diameter rotor. It has been tested at -45 degrees Celsius, and a wind speed of 62.5 metres per second. It also has the low-voltage ride-through capacity, a necessity for installation in Chinese wind farms. The machine is descended from the SL5000, which is also being tested. 5. ALSTOM HALIADE Prior to Siemens 75-metre blade, the Haliade held the record with its 73-metre blades co-developed with LM Wind Power. The turbine, which is already set to form the bulk of France's 3GW offshore programme, uses a direct-drive permanent-magnet generator with a 7.5-metre diameter and has been installed Carnet in the Loire-Atlantique region. MULTIBRID M5000 ARENA 6. AREVA M5000 Originally developed by Aerodyn in the late-90s the 5MW machine is one of the few offshore turbines on this list that is in use commercially (at the Alpha Ventus project in the German North Sea). Last year, the Areva announced it was upgrading the turbine's rotor from 113-metres to 136-metres. It is set to be used on one of the French offshore projects in the English Channel. 7. BARD 5MW Independent manufacturer/ project developer Bard installed its first turbines in 2008 off the island of Borkum in the North Sea. Since then it has installed a large part of the 400MW project, although the company itself appears to be in difficulty and is looking for a buyer. Featuring a 122-metre rotor diameter, the Bard 5.0's box-type nacelle is 14 metres long, 8.5 metres wide and 8 metres high. XEMC 8. ХЕМС 5MW Like many nese bulk the design comes from Europe - in this case Darwind in the Netherlands.The turbine wind rotor is 100 metres above the ground and blades measure 115 metres in diameter. It is set to be the first Chinese turbine to be installed in European waters. It is also rumoured to be installed on the US Fishermen's Energy offshore project on the US east coast. 9. GAMESA G5MW Gamesa's 5MW offshore turbine is essentially a scale-up of its 4.5MW onshore machine. The turbine, which is currently being tested in Gran Canaria, has a 128-metre rotor and like most offshore turbines is designed for class I wind speeds. The 4.5MW version has a 136-metre rotor and is essentially designed for low wind sites, making it the largest turbine for that classification. E3 10. GE 4.1-113 GE's 4.1MW offshore turbine is currently being tested in Gothenburg harbour. The turbine is essentially a return to offshore for GE after ditching the sector back in 2003. Developed from technology acquired from Scanwind, the direct drive turbine has a 113-metre rotor.
