Intelligent evolution to boost energy production
The SG 2.6-114 power curve, showing an increase in output over the SG 2.1-114.
The SG 2.6-114 wind turbine is integrated into the Siemens Gamesa 2.X platform, a benchmark in the market thanks to its excellent capacity factors, high profitability, and installed base of over 50.7 GW. Designed for medium- and high-wind sites, it complements the Siemens Gamesa 2.1 MW offer in projects requiring higher nominal power. With a 114-meter rotor, various tower options and increased nominal power of up to 2.625 MW, it guarantees maximum efficiency at a reduced Levelized Cost of Energy.
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.
