Direct Drive Technology

A turbine generator with a simplified and robust design that ensures efficiency even at high load returns.
Proven technology from the offshore wind industry, which has made Siemens Gamesa the global market leader in this segment.
High reliability and, as a consequence, an outstanding availability, confirmed by measurements on the more than 3.3 GW of installed onshore direct drive turbines worldwide.
