GE’s 1.7-103 Wind Turbine
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

GE’s 1.7-103 Wind Turbine
The 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.
• Increased output – less downtime through turbine to turbine communication
• Productivity – enhanced diagnostics with Mark*VIe controller from GE
• Smooth grid integration – with wind farm to grid communication
• Improved grid voltage support in the area – with wind farm to wind farm coordination
• Technical support around the world – turbine to remote monitoring communication
• New revenue streams – advanced forecasting algorithms and storage ready
Building Upon the Proven Performance
The 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.

GE’s 1.7-103 Wind Turbine
Technical Description
GE’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.
Specifications:
• Designed and certified to IEC 61400-1
— IEC Class S
• Standard temperature option
• Standard tower corrosion protection; C2 internal and C3 external
with optional C4 internal and C5 external available
• Rotational direction: Clockwise viewed from an upwind location
• Speed regulation: Electric drive pitch control with battery backup
• Aerodynamic brake: Full feathering of blade pitch
Features and Benefits
• Highest capacity factor in its class for India
• Grid friendly options are available
— Enhanced Reactive Power, Voltage Ride Thru, Power Factor Control
• Wind Farm Control System; WindSCADA*
• GE proprietary 50.2-meter blade
• Available in both 50 Hz and 60 Hz versions for global suitability

GE’s 1.7-103 Wind Turbine
Construction
Towers: Tubular steel sections provide a hub height of 80 meters.
Blades: GE 50.2-meter blades.
Drivetrain components: GE’s proven design gearboxes, mainshaft, and generators with appropriate
improvements to enable the larger rotor diameter on the 1.7-103 machine.
Enhanced Controls Technology
The 1.7-103 wind turbine employs two enhanced control features:
• GE’s patented Advanced Loads Control reduces loads on turbine components by
measuring stresses and individually adjusting blade pitch
• Controls developed by GE Global Research reduce loads including at near rated
wind speeds to improve Annual Energy Production (AEP)
Optional Condition Monitoring System
GE’s Condition Monitoring System (CMS) and SCADA Anomaly Detection Services, a complementary suite
of advanced condition monitoring solutions, proactively detect impending drivetrain and whole-turbine
issues to enable increased availability and decreased maintenance expenses. Built upon half a century of
power generation drivetrain and data anomaly monitoring experience, this service solution is available as
an option on new GE units and as an upgrade.
