2© 2014 Proprietary Information

Since entering the wind industry in 2002,

GE Power & Water’s Renewable Energy

business has invested more than 2 billion

dollars in next generation wind turbines.

Whether at the turbine, plant, or grid level,

GE continues to focus on providing more

value for our customers. Through the use of

advanced analytics, GE’s Renewable Energy

business is redefining the future of wind

power, delivering on proven performance,

availability and reliability. With the

integration of big data and the industrial

internet, the company is helping to manage

the variability of wind to provide smooth,

predictable power. Our current product

portfolio includes wind turbines with rated

capacities ranging from 1.6 MW to 3.2 MW

and support services ranging from

development assistance, site optimization

and operation and maintenance.

GE’s 1.7-103 Wind TurbineThe 1.7-103 is GE’s first brilliant wind turbine for India. It provides a 30% increase in annual energy

production (AEP) compared to its predecessor, with an increase in blade swept area that allows for

greater energy capture and improved project economics for wind developers and operators. In addition,

GE’s proprietary 50.2-meter blade uses the same proven aerodynamic shape as the blades on the

2.75-103 turbine.

How do you define brilliance? GE is redefining the future of wind power by integrating the Industrial

Internet with GE’s industry-leading power conversion technology, enabling “grid friendly” integration

of wind farms around the globe. By helping to manage the variability of wind, GE is working to provide

smooth, predictable wind power to the world regardless of what Mother Nature throws its way.

Building Upon the Proven PerformanceThe evolution of GE’s 1.5 MW turbine design began with the 1.5i turbine introduced in 1996. The

65-meter rotor was increased to 70.5 meters in the 1.5s, then to 77 meters in the 1.5sle turbine which

was introduced in 2004. Building on the exceptional performance and reliability of the 1.5sle, GE

introduced the 1.5xle with its 82.5-meter diameter in 2005. Subsequent improvements in design led to

the 1.6-82.5 turbine, introduced in 2008. Ongoing investment in this proven technology resulted in the

introduction of GE’s 1.7-103 wind turbine with a 103-meter rotor. This product evolution provides an

increased capacity factor while increasing AEP by ~30% at 6.5 m/s.

Incremental changes to the 1.7-103 wind turbine resulted in a significant performance increase. These

enhancements include greater blade length and controls improvements, resulting in an increase in AEP,

capacity factor and controlled sound performance. Designed with high reliability to provide continued

operation in the field, GE’s 1.7-103 delivers excellent availability comparable to the GE units operating in

the field today.

Best-in-class capacity factor


Technical DescriptionGE’s 1.7-103 wind turbine is a three-blade, upwind, horizontal axis wind turbine with a rotor diameter of

103 meters. The turbine rotor and nacelle are mounted on top of a tubular steel tower, providing a hub

height of 80 meters. The turbine uses active yaw control to keep the rotor pointed into the wind. The

turbine is designed to operate at a variable speed and has an active blade pitch control (designed to

regulate turbine rotor speed), and a doubly-fed induction type generator along with power electronic

converter system.
