SG 2.2-122

Onshore wind turbine

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.

Other models in the platform

Model	Rotor Dia.	Wind type
SG 2.1-114	114 m	For low to medium wind
SG 2.6-114	114 m	For medium to high wind
SG 2.9-129	129 m	For low to medium wind

A high performer in low-wind sites

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.

A 60-meter blade increases the swept area to 11,690 m2, while its aerodynamic profile helps to keep noise levels low. The electrical system is shared by all other solutions with 2.1 MW of nominal power.

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.

Technological Highlights

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.

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.
