Siemens Gamesa has completed the installation of the largest wind turbine ever built. On April 2, 2024, the final blade was mounted at the Østerild test center in northern Denmark. This marks a major milestone in offshore wind technology.
Setting a New Record for Offshore Wind
The new model, SG DD-276, has a rotor diameter of 276 meters and a rated capacity of 21.5 megawatts. It is now the largest wind turbine installed in the world, surpassing China’s Mingyang Smart Energy 20MW turbine. The nacelle and hub together weigh close to 1,000 tons.
Compared to earlier 14MW models, the SG DD-276 offers a 50% power increase and a 37% larger swept area. This could boost Annual Energy Production (AEP) by 30–35% at the same site.
Supporting Europe’s Energy Future
Vinod Philip, CEO of Siemens Gamesa, said, “Europe needs wind energy, and wind energy needs Europe.” Offshore wind, powered by the largest wind turbine models, is key for Europe’s energy independence.
This project received €30 million from the European Innovation Fund, highlighting its strategic importance.
Careful Testing Before Commercial Launch
Despite the excitement, Siemens Energy has kept the SG DD-276 as a prototype for now. CEO Christian Bruch emphasized that the company will run full performance and safety tests first.
The Danish Energy Agency has already certified the model. The tests will continue until 2027 before a decision on mass production.
Industry Impact and Challenges
While larger turbines offer more power, they also bring challenges. Transport, installation, and maintenance costs rise with turbine size. Experts believe the success of the largest wind turbine will depend on its efficiency and reliability.
Still, the SG DD-276 shows Europe’s determination to stay competitive. Siemens Gamesa has taken a bold step forward, challenging China’s lead in offshore wind technology.
The world will watch closely as Siemens Gamesa’s largest wind turbine shapes the next era of renewable energy.
