Low power density, maximum profitability
The SG 2.1-114 power curve, showing electrical power output at different wind speeds.

Boasting a 114-meter rotor, tower options from 68 to 153 meters and nominal power of 2.1 MW, the SG 2.1-114 is one of the product proposals from the Siemens Gamesa 2.X platform.

This model is a benchmark thanks to its low power density, allowing maximum profitability at sites with medium and low winds. A backlog of orders and strong market presence are evidence of this.

Optimized solutions for Class S sites mean it can adapt to specific wind and environmental conditions in markets like India, China and Brazil.


Technological highlights
Our onshore approach is focused on geared technology, in which we have extensive knowledge and expertise. The hallmarks of Siemens Gamesa turbines are: reliability, robustness and a modular, flexible design for optimum adaptation and maximization of production at any site and in all wind conditions.
This turbine is equipped with blades made of fiberglass reinforced with epoxy or polyester resin. Together with the state-of-the-art aerodynamic profile, we can produce lighter blades having greater strength and improved dynamic behavior with less load transmitted to the rest of the components.
Turbine sensors continuously transmit data to our diagnostic centers, enabling the early detection of anomalies and preventing potential failures. By analyzing vibration patterns we can optimize your service plan and anticipate repairs before serious damage occurs.
