Siemens Gamesa, your trusted technology partner

The SG 2.9-129 wind turbine for medium to low-wind sitesThe SG 2.9-129 wind turbine is the latest Siemens Gamesa onshore turbine developed to meet the medium to low-wind site and market conditions of the American market. Theturbine is designed based on the foundation of the proven2.3 MW geared product series, one of the most robust andsuccessful turbine lines in the market, with over half of the10,549* units installed globally installed in North America(more than 7,300 units). The product configuration maintains a similar design, utilizing components from its predecessor, the SWT-2.625-120.

To deliver the lowest Cost of Energy and maximize performance across various sites in the U.S., the SG 2.9-129 is designed with the higher capacity factor our customers demand. This improved model demonstrates our ability to offer flexible solutions for every context while delivering a certified 25-year design lifetime, standard.

Proven technologyThe experience acquired through our latest products, specifically in the optimization of design, prototyping, validation and industrialization processes, along with enhanced design tools such as FEA, thermal modeling and grid analysis has been a key factor in the development of the SG 2.9-129 wind turbine.

Siemens Gamesa has incorporated proven technologies into this wind turbine, boosting capacity and simplifying maintenance.
