GE’S DIGITAL WIND FARM
Since entering the wind industry in 2002,
GE Power & Water’s Renewable Energy
business has invested more than $2 billion
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 to site planning,
operation and maintenance.

GE’s Digital Wind FarmGE’s Digital Wind Farm is a product portfolio comprised of GE’s newest wind turbines, predictive analytics,
and performance optimization controls, that over the course of a wind farm’s life will improve its energy
output by up to 20% compared to previous technology with a standard configuration. By using GE’s 2.0-
2.4MW wind turbine, combined with multiple rotor lengths and tower height options, a wind farm can be
optimized to address environmental effects such as sheer, wakes, and turbulence intensity. This 2.0-2.4MW
turbine model leverages a universal machine head, hub and DTA to simplify physical optimization of wind
farm layout, and reduce installation time and cost. By simulating site characteristics to select a unique
turbine configuration for every pad, the annual energy production (AEP) of a wind farm will increase when
compared to one built with a single turbine type.
The second portion of Digital Wind Farm is optimization of turbine performance and equipment life through
use of predictive analytics software. Predix, an open developer software platform, will provide the digital
infrastructure beneath the 2.0-2.4 turbine hardware of the Digital Wind Farm, allowing a customer to
connect, monitor, predict, and optimize both unit and site performance. Through constant collection of
real time data, weather, component messages, service reports, and performance of similar models in GE
fleets, a predictive model is built. This model serves as the basis for forecasting all maintenance needs and
creating a ‘plan of the day’ for wind farm operation. This digital feedback loop will allow the farm operator
to eliminate unplanned maintenance events, reduce operating expenses and capture higher power output
from machines that are operating more efficiently and reliably.
Finally, the Digital Wind Farm employs GE’s Wind PowerUp* Services, a combination of data analytics and
controls solutions, to maximize farm output. By understanding the real time environmental conditions the
wind farm is experiencing, PowerUp will instruct individual turbines to boost performance in response to
changes in wake, shear, and turbulence. This enables each turbine to produce more energy over the project
lifecycle, without compromising turbine design life.

GE’S DIGITAL WIND FARM
Building Upon Proven TechnologyThe 2MW Platform:The evolution of GE’s 1.5 MW turbine design began with the 1.5i turbine introduced in 1996. The 65-meter
rotor diameter turbine soon was increased to 70.5-meters in the 1.5s, then to 77-meters in the 1.5sle
turbine that 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 introduction of the 1.6-82.5 turbine in 2008—followed by the 1.6-87 in 2011, and ultimately the 1.85-
82.5 and 1.85-87 in 2013. Ongoing investment in the industry workhorse resulted in the introduction of
GE’s 1.6-100 and 1.7-100, wind turbines with a 100-meter rotor. This product evolution provides increased
capacity factor while increasing AEP by 20–24% over the previous models. Built from the maturity of its
predecessors, the 2.0-2.4MW platform evolution provides increased capacity factor while increasing AEP
and application space of GE’s 1-2MW platform of products.
Significant component enhancements to the 1.x models have resulted in a substantial performance
increase over previous technology, enabling the use of a 107m and 116m rotor on the 1.x series, and
a nameplate range of 2.0-2.4MW (with applicable rotor). These enhancements include: new [delete
“optimized”] aerodynamic design enabling a greater blade length (116m rotor), larger bedplate, generator
frame and gearbox, controls improvements, and enhanced power conversion capabilities resulting in
an increase in nameplate and AEP. Designed for high reliability, GE’s 2.0-2.4MW platform can provide
excellent availability, comparable with the 1.x series units operating in the field today.
