Project Motivation
Chambersburg is a unique smart-grid based self-sufficient electric utility in Pennsylvania. It is
a real-world example of how a small utility can be successful. Chambersburg is famous for its
low electric price rates and it is time to add another title to Chambersburg, “Green Energy
Generation”. In August 3, 2015, President Obama and EPA has announced a new Clean
Power Plan, which is requiring a dramatic reducing the Carbon pollution from power plants.
So it is a great opportunity to introduce wind power into Chambersburg energy portfolio, which
could not only resolve the carbon emission regulation issues but also can expand
Chambersburg’s electric generation profile.
Project Objects
a. A Detail Feasibility Study of Wind Turbine installation includes proper turbine
models and optimal pole heights
b. A Construction Strategy
c. An Output Study of The Designed Wind Turbine
d. A Financial Estimation of Possible Cost and Payback Period

3. Pennsylvania Annul Wind MapPennsylvania Annul Wind Map
From the Pennsylvania wind map we can see the location of Chambersburg is besides the town
of York and the annual average wind speed at 80m in Chambersburg is around 7 m/s. 7 m/s is a
relative low wind speed for construction of wind turbine farm. Comparing with other places in
Pennsylvania such as Sandy Ridge, Allegheny Ridge, and Mill Run, which have a higher wind
speed around 10 m/s, Chambersburg may require special designed low wind speed wind turbine
for an efficient energy output.

4. Recommended Turbine ModelRecommended Turbine Model
Reasons for Choosing NPS 60-24 Model for Chambersburg
•Low wind speed design
The Turbine is designed for specific low wind speed (10 m/s), which is suit to
Chambersburg low wind speed region.
•Easy to construction
The Turbine’s hub is designed in 23 meters, which is relatively convenient to
install and suit to the construction landscape.
•Plug and Play
The Turbine is design to simplify grid interconnect, because the construction
ground is located besides a transmission station, it is essential to consider that the
simplicity of plug and cut-off the wind turbine system.
•Quiet
The gearless design, advanced blades, and low rpm and tip speed, all contribute to
low noise levels. Considering the residential in Chambersburg, Quietness is a unique
benefit to Borough of Chambersburg, which may bring positive public image.
•Easier Permitting
The lower hub height helps Chambersburg to permit on site wind power
generation proposal.

Summary of Recommendations
Financially, the project cannot be justified due to the long payback period of time which is about 40
years. It will greatly exceed the wind turbine designed life which is 20 years.
The wind turbine may provide other benefits to Chambersburg such as improved public image through
green generation and being a new technology adaptor.
