10 Biggest Wind Turbines

by Laurence Kellett in Lunchtime Read | posted:


Renewable energy sources are becoming more and more important around the world, as our energy consumption increases year-on-year, our natural energy sources deplete at a much quicker rate. Solar power, wind power, water turbines, biogas and many more are all ways that we are trying to combat the growing problem of depleting energy sources and global warming.

 Wind Turbines, in particular, have been cropping up around the world, on hills, in the sea and in wind farms for many years now. Part of the goal with wind turbines is not only to just produce green energy, but produce it more efficiently – manufacturers are constantly challenging themselves to make greener, larger power generating, wind turbines. A study by Swiss and Dutch Scientists showed that the larger the turbine is, the greener the energy.

The 10 biggest turbines in the world!

All of the turbines here exist, even if they are not commercially available yet – criteria is based on capacity and, where this is the same, on blade diameter.


10. Bard 5MW


Independent manufacturer, Bard, installed its first turbines in the North Sea, in 2008. Since then, it has played a huge part in the installation of the 400MW project. The company however is in financial trouble and has recently been put up for sale by its Russian owner.

Hub height: 90 Metres

Blade diameter: 122 Metres

Power: 5 Megawatt


9. Gamesa G5MW


Gamesa’s new 5MW turbine is essentially an upscale version of its 4.5MW onshore turbines, only a larger version. It is currently being tested in the Gran Canaria, and is designed for class 1 wind speeds and near-shore areas.

Hub height: 90 Metres

Blade diameter: 128 Metres

Power: 5 Megawatt


8. Areva M5000


The Areva M5000, at least in theory, is one of the oldest turbines in this top 10, and was originally developed by Aerodyn in the late 90’s. Last year the company announced it was upgrading the rotors on the M5000 from 113 meters to 136 meters, putting it at number 7 on our list. They also recently announced a new M5000-135, with a hub height of 130 metres!

Hub height: 90 Metres

Blade diameter: 136 Metres

Power: 5 Megawatt


7. Sinovel SL6000


Currently being tested in China, where it is the country’s largest wind turbine, at -45 degrees Celsius and a wind speed of 62.5 metres per second, this is robust and powerful turbine takes the number 6 spot on our list. Sinovel have also claimed to be in the latter stages of designing a 10MW machine!

Hub height: –

Blade diameter: 128 Metres

Power: 6 Megawatt


6. Alstom Haliade


Yet another 6MW offshore turbine, Alstom’s Haliade is currently being tested in France. Apart from being number 6 on our list, the Haliade used to hold another record of having the biggest blades, at 73-metres, before the introduction of Siemens’ 75 -metre blade.

Hub height: 100 meter

Blade diameter: 150.95 Metres

Power: 6 Megawatt


5. Siemens SWT-6.0 150


The Siemens SWT-6.0 150 only currently exists as an onshore prototype but will soon hold the title for the longest blade on a 6MW turbine at 75-metres long. Apart from being number 5 on our list, the turbine has a lot to live up to, with its predecessor, the SWT 3.6 120, is generally being  regarded as the best turbine in the offshore sector.

Hub height: 100 Metres

Blade diameter: 154 Metres

Power: 6 Megawatt


4. Repower 6M Series


Repowers 6.15MW onshore/offshore turbine is the largest turbine currently installed on the open sea, as it aims to build on the success of its 5MW predecessor, much like the Siemens, below.

Hub height: 85-95 Metres

Blade diameter: 126 Metres

Power: 6.15 Megawatt


3. Samsung S7.0 171 7MW


Samsung’s 7MW was only completed in October, and was built at a test site in Scotland. It has the world’s longest turbine blade, at almost 85 metres long!

Hub height:

Blade length: 85 Metres (Diameter approx. 175)

Power: 7 Megawatt


2. Enercon E126 7.5MW


Whilst a lot of these wind turbines are designed for the offshore market, or are capable of off and onshore placement, the Enercon E126 is purely designed for the onshore sector. It has a power rating of 7,580 kW, and works using a gearless, variable speed, single blade adjustment concept.

Hub height: 135 Metres

Blade diameter: 127 Metres

Power: 7.58 Megawatt


1. Vestas V164 8MW


The Vestas V164, sitting at No.1 on our list, and also the latest edition, came into the game in January, 2014 – almost 3 years after it was first unveiled in London. Curiously, the V164, an offshore turbine, is geared. It also features a lightweight nacelle that won the design innovation category in Wind power monthly’s annual wind turbine awards.

Hub height: Site specific

Blade diameter: 164 Metres

Power: 8 Megawatt
