Siemens Gamesa introduces new turbine for the American market

With its beginnings in apple orchards, this company has returned to its green roots by machining large parts for the wind-power industry.


Siemens Gamesa Renewable Energy (SGRE) has launched the new SG 2.7-129 wind turbine designed to address the diverse wind conditions of the American market.

By optimizing turbine technology to deliver a higher capacity factor at a lower cost of energy, the powerful new turbine delivers sustainable value for the full lifecycle of the project.

Production of the SG 2.7-129 is targeted to commence in the U.S. in early 2019. The blades for this turbine will be manufactured at the company’s blade manufacturing facility in Fort Madison, Iowa, and the nacelles and hubs will be assembled at Siemens Gamesa’s nacelle facility in Hutchinson, Kansas.

The SG 2.7-129 was developed with an eye toward increasing energy production for sites with medium- to low-wind conditions in the U.S. It features modularized components for increased flexibility and reliability. It also employs advanced technology with a 129-meter rotor, boasting an increased swept area of 16 percent compared to its predecessor, the SG 2.6-120. Additionally, the SG 2.7-129 features a state-of-the-art drive train that has been optimized to deliver maximum energy capture.


The product design also incorporates several added safety and operational benefits related to the service and maintenance of the turbines, including increased accessibility of key components and access to the weather station from inside the nacelle.

“We are very excited to introduce the new SG 2.7-129 to our portfolio — the next generation in a fleet of turbines with a proven track record and high availability,” said José Antonio Miranda, Onshore Americas CEO, Siemens Gamesa Renewable Energy. “With an increase of more than 8 percent in annual energy production compared to its predecessor, this turbine will deliver greater returns and is another important step in reducing the levelized cost of energy. This product is also unique in that it was co-designed to include best practices from both former companies, making it a best-in-class wind turbine for the U.S.”

The SG 2.7-129 is the latest addition to the Siemens Gamesa 2.X product platform. Combined with the SG 3.4-132 and the SG 4.2-145 wind turbines, these products can address all of the diverse needs of the U.S. market.

With 73 GW of onshore installed capacity worldwide and several decades of joint experience, Siemens Gamesa combined proven design components and lessons learned from previous platforms into the development of the SG 2.7-129, taking another step toward increased competitiveness and continuously reducing the levelized cost of energy.
