SGRE builds world’s largest wind turbine blade

Siemens Gamesa Renewable Energy (SGRE) has begun construction of the world’s largest wind turbine blade test stand in Aalborg, Denmark. The site will be capable of performing full-scale tests on the next generations of SGRE rotor blades and is expected to be fully operational before the end of 2019.

The investment in testing will generate more savings for wind turbine clients of Siemens Gamesa. Siemens Gamesa, the second largest wind turbine maker, will also gain from significant reduction in technical issues. It can also deliver more innovative and reliable wind turbines.

«The first tests will be on the 94 meter-long blades for the SG 10.0-193 DD offshore wind turbine, which are almost the same length as one soccer field. We are however building the test stand to accommodate the blade sizes that we will see in the future», said Vicente García Muñoz, Head of Validation Means Management at SGRE.

The gigantic structure in Aalborg will have more steel rebar reinforcement per square meter than a wind turbine foundation, so that it has the capability to accelerate the test and prove full reliability over the lifetime of the blade in the shortest possible time, while full respecting IEC regulations.
