Siemens Gamesa has begun production of its 377-foot (115 metre) B115 blades at its Aalborg facility in Denmark.

The company said it is building its biggest wind turbine yet, the SG-14 236 DD. With a planned rotor diameter of 236m, this turbine will sweep an area of 43,500 square metres with each spin and generate 14MW of power with a power boost. The turbine’s capacity can even hit 15MW. 

The photo shows the mould that will be used to manufacture the blades. Siemens’ technology allows them to make the blade without any glued joints in one piece and engineers at the Denmark facility will use the mould to put together fibreglass and epoxy resin that majorly makes up the blade.

By using a recyclable resin that melts away, Siemens plans to make the components of its turbines recyclable and repurpose them completely by the year 2040. Once the B115 blades are manufactured, they will be tested in a prototype turbine by the company later this year.

As massive as this blade is, MingYang Smart Energy’s MySE 16.0-242 turbine will have 118m blades and a power output of 16MW.
