Siemens Gamesa Sg 2.2-122 Wind Turbine
SG 2.2-122 WIND TURBINE
SG 2.2-122
Onshore Wind Turbine
The SG 2.2-122 has one of the greatest capacity factors in low-wind, low-turbulence sites, offering a 8% increase in annual energy production compared to the SG 2.1-114 model.
GREATER CAPACITY FACTOR IN LOW-WIND SITES
Boasting a 122-meter rotor combined with a 2.2 MW generator, the SG 2.2-122 is especially suited to Class S sites, thanks to its extremely low power density for a reduced Levelized Cost of Energy.
KEY FACTS
-Minimum power density and high efficiency for reduced LCoE -One of the greatest capacity factors for low-wind low-turbulence conditions -Proven technology with optimized design, prototyping, validation and industrialization processes -High reliability, with an average fleet availability greater than 98%

ONE OF THE GREATEST CAPACITY FACTORS IN LOW-WIND SITES
The SG 2.2-122 wind turbine is an addition to the Siemens Gamesa 2.X product platform, a benchmark in the wind power sector thanks to its excellent capacity factor, high profitability. Specifically optimized for low-wind, low-turbulence conditions, this model seeks competitive positioning in markets with locations of this type, such as China and India, through its low power density and reduced Levelized Cost of Energy.
TECHNOLOGY HIGHLIGHTS
REINFORCED FIBERGLASS BLADES
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.
REMOTE DIAGNOSTICS SERVICES
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.
RELIABLE GEARED TECHNOLOGY
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.
DINOTAILS® NEXT GENERATION
As an aerodynamic blade add-on, DinoTails® Next Generation reduces the sound power levels by using a serrated trailing edge mounted at the blade and adding finer combs in between the teeth. This world-leading noise reduction technology enables us to create value for our customers by maximizing AEP and reducing the LCoE in sites with noise constraints.
