LM wind power, in collaboration with Alstom want to develop the world's longest wind turbine blades. The new blades will be designed to fit Alstom's 6 MW wind turbine. The first prototype made out of polyester and glass fiber will be created in the company’s Danish factory in Lunderskov.

According to company officials, Alstom prototype sites from Europe will have such blades by the end of 2012.

The length of the new blade has not been specified, but will be longer than LM's longest blade, the 61.5 meters/202 feet 61.5P2, which is manufactured at the company’s Lunderskov factory in Denmark.

Mr Roland Sundén CEO of LM wind power said that "This new blade builds on the innovative features developed for our recent design, offering an additional annual energy production of 4% to 5% compared to standard blades."

Being one of the world’s largest supplier of blades, brakes and services to the wind industry, LM wind power has created about 130,300 blades over a time of 30 years.
