Reports were released in June 2024 that Siemens Energy (Munich, Germany) was looking to introduce a 21-megawatt (MW) wind turbine platform to the market. Since then, several sources say there has been activity in Denmark at the company’s subsidiary, Siemens Gamesa’s (Zamudio, Spain), Østerild test center. Here, sources suggest that Siemens has completed installation of the blades of this “record-breaking” prototype. 

Last year, RenewBiz.com reported that the company had previously received €30 million in EU funding to test “the world’s most powerful wind turbine prototype.” Now, according to , a prototype certificate published recently by the Danish Energy Agency “has officially confirmed the model can produce up to 21.5 MW of power,” and that the model’s rotor diameter is 276 meters.

This power rating and rotor diameter would put the wind turbine manufacturer ahead, not only dwarfing its own existing 14-MW SG 14-22 DD 236 wind turbine, but also surpassing previous record-holder MingYang Smart Energy (Guangdong, China) that announced its 20-MW MySE18.X-20 platform in October 2024.

Details have not been verified by Siemens Gamesa itself, but the company released the following statement to : “The installation in Østerild, Denmark, is a test facility partly funded by the European Commission. We will only decide whether we will ultimately install a new product in a commercial project after careful testing. However, we fundamentally believe in the offshore market and the expansion of capacities at sea must be implemented quickly and consistently to reach the ambitious climate targets. Our 14-MW turbine has everything it needs for that.”
