Siemens Gamesa is producing new and bigger wind turbine blades to boost annual energy production. The Spanish-German wind giant has begun its production of the first B115 blades in Aalborg, Denmark, which will be used on their SG 14-236 DD offshore wind turbine. 

The blades will have 14 megawatts and a rotor diameter of 236 meters. While the SG-140236 prototype is 377 feet long and will be tested on the company's test stand in Aalborg and østerild test center later this year. 

It was in December last year when the SG 140222 DD prototype delivered electricity to the grid in østerild. 

IntegralBlade and RecyclableBlade Technology

Siemens Gamesa used its IntegralBlade technology to manufacture the blade. With this technology, the blades are cast in one piece and are made from fiberglass-reinforced epoxy resin without glued joints. The blades will also feature the ReclableBlade technology. 

The RecylableBlade is the world's first-ever recyclable wind turbine blade that shows the company's commitment to sustainability and circularity. 

The recyclable resin system allows blade recycling and recovery of reinforcement and the resin matrix. With that, the recovered blade materials can be repurposed and reused, while the resin is designed to slow reactivity, further improving processability and allowing it to cure faster compared to traditional materials. As a result, there is a lower cycle time in manufacturing the blades.

A Move to Perform Better?

Just recently, Siemens Gamesa received profit warnings and losses due to its underperformance which forced Siemens Energy to issue a profit warning and withdraw its guidance. Its share price fell over 50 percent in the past year. Moreover, Siemens Gamesa struggled with the release of the 5X, which did not perform well as expected. 

And it's not only that-the global supply chain crisis, increasing energy prices, and inflation have negatively impacted the company. 

Siemens Gamesa continues to expand its footprint as it will install three wind farms in the provinces located in northwest Spain with Greenalia.

The three wind farms will have 22 of Siemens Gamesa's 5.0-145 turbines, which is one of the most powerful models of the company and is suitable for areas that experience medium-level wind speeds. Along with the installation, the agreement between the two companies will include turbine maintenance for 25 years. 

This agreement will help strengthen Siemens Gamesa's relationship with Greenalia and will increase the company's footprint in Spain, one of its key markets. The three wind farms will provide electricity to power at least 90,000 households in the province of A Coruña. 

With these new blades and new projects, Siemens Gamesa may finally be able to move away from the eye of the storm.
