Siemens Gamesa was formed in 2017 when Siemens Wind Power merged with the Spanish company Gamesa. The resulting entity became one of the world’s top three wind turbine manufacturers, with a particularly strong position in offshore wind. In 2023, Siemens Energy completed a full takeover, delisting the company and integrating it as a wholly owned subsidiary.
The offshore business is where Siemens Gamesa really shines. Its SG 14-222 DD turbine — a 14+ MW direct-drive machine with a 222-meter rotor — is among the most powerful in commercial production. Major offshore wind farms around the world, including projects in the North Sea, Taiwan Strait, and U.S. Atlantic coast, use Siemens Gamesa equipment. The direct-drive design eliminates the gearbox, reducing maintenance needs and improving reliability in harsh marine environments.
The onshore business serves markets across Europe, the Americas, India, and Africa with a range of turbines optimized for different wind conditions. Siemens Gamesa also runs a substantial service operation maintaining tens of thousands of installed turbines globally. The company has faced significant challenges — quality issues with onshore turbine platforms led to costly warranty provisions, and offshore supply chain delays created project overruns. These problems contributed to billions in losses at Siemens Energy. The company has roughly 28,000 employees and has been working through a restructuring program to restore profitability while continuing to deliver on its massive offshore order backlog.
