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.
