The Beginning

  • In the spring of 2001 two groups formed thesis proposals dealing with wind energy

  • The two groups had two distinct goals and objectives

  • We combined two project proposals to form one with two main sections


Slide3 l.jpg

The Virginia State-Based Anemometer Loan Program (SBALP)

  • Purpose - spur the development of the Virginia’s wind resource

    • Help facilitate the development of widely distributed wind expertise throughout the nation

    • Allows landowners to measure their wind energy resource

    • Help Virginia and the National Renewable Energy Laboratory collected data that can be used to validate wind resource models

First megawatt turbine in operation (Vermont)

1980s

Large wind farms in US

1888

First electricity generating turbine constructed in Denmark

1000AD

Grain-grinding windmills in the Middle East

Slide6 l.jpg

What Is Wind?

  • Driven by the sun

  • Differences in pressure

  • Hadley convection cells

  • Coriolis Effect

Hadley Cell Model (Western Illinois University)


Slide7 l.jpg

Wind Basics

  • Wind speed increases with height

  • Small increases in wind speed result in large increases in power

  • Tall towers often needed for clearance above obstacles (turbulence)



Slide9 l.jpg

Wind Resource Assessment

  • Is there enough wind in a particular spot to support a wind turbine?

    • A year’s worth of data is usually the minimum study period

    • Class II needed for small wind, Class IV for large


Slide10 l.jpg

Siting of Wind Turbines

  • The concept of micrositing

  • Topographical maps

  • Freedom from obstructions

Slide19 l.jpg

Virginia interested

Over 200 inquiries

Approximately 70 applications

Expansion of program

Have groups continue the thesis in upcoming years

Wind Powering America (WPA) proposal

SBALP Conclusions


Slide20 l.jpg

SBALP Recommendations

  • Better outreach to public

  • More stringent application process, include more parameters

  • Expand website

  • Establish school contact, answering machine, mailbox, etc.


Slide21 l.jpg

Wind Energy Potential at JMU

  • 30-meter Meteorological (MET) tower that we have now can support a turbine

  • East (CISAT) campus in valley, but above immediate surroundings

  • Wind resource purely anecdotal

  • More data necessary

  • Potential for small-scale wind turbine exists



Slide23 l.jpg

30-Meter MET Tower

  • Installation next week

  • Wind speed and direction

    • Instruments at 10, 20 and 30 meters

  • Manufactured by Rohn

  • Specially designed for Bergey WindPower turbines

  • 700 Bergey Excel turbines installed


Slide24 l.jpg

Objectives

  • Analyze:

    • Relevant issues and public misconceptions

    • Preliminary economic analysis of wind turbine

    • Non-market benefits


Slide25 l.jpg

Regulations

  • No restrictions on proximity to roads, parking lots, etc.

  • Zoning, permitting, etc. handled by JMU

  • Federal Aviation Administration (FAA) requirements


Slide26 l.jpg

Turbine Testing and Safety

  • Proven technology – 150,000 small turbines around globe

  • Small turbine standards – American Wind Energy Association

  • Dynamic and duration testing through accredited test laboratory

  • Turbine failure extremely rare

  • Bergey – passive overspeed protection, heavy-weight material, and fiberglass blades


Slide27 l.jpg

Visual Perception

  • Barrier to wind turbine development

  • Misconception turbines will ruin landscape

  • Similar to other structures in area

  • Location already developed (parking lot, light towers)


Slide28 l.jpg

Avian Issues

  • Misconception on wind turbine impact

  • More problematic where there is a higher concentration of raptor species

  • Most studies on large-scale wind farms

  • Small swept-area


Slide29 l.jpg

Bergey Excel Noise

  • At 300 ft in 25 mph winds sound was measured at 54-55 dB

  • This means it would only be detectable if the ambient background noise were less than 52.5 dB

  • Ambient sound at parking lot measured at 65-70 dB standing on the tower platform

  • Dr. Chen lecture 20 ft away measured at 55-60 dB



Slide31 l.jpg

Required WAsP Inputs

  • Wind Atlas

    • Meteorological Tower, Observed Wind Climate

  • Turbine Site

    • Obstacles, power curve

  • Site Description

    • Topography, Roughness, Obstacles

  • Resource grid


Slide36 l.jpg

Economic Analysis

  • Cash flow analysis

  • Simple and discounted payback

  • Sensitivity analysis

    • Reduce JMU’s initial investment

    • Verify wind resource

  • Raise local and state awareness

  • Encourage wind energy use

  • Provide opportunity to educate


Slide47 l.jpg

Virginia’s electricity production on average emits 1.83 pounds of CO2 per kWh

Average tree consumes 14.7 pounds of carbon dioxide each year

The combustion of a gallon of gasoline produces 19.59 pounds of CO2

The average gas mileage of an American car is 17 mpg

WAsP model predicted annual energy output of 11.87 MWh

Equivalent to

21,722 lbs CO2 from power generation

1,478 trees

1,108 gallons of gasoline

18,850 automobile miles traveled

Emission Benefits


Slide48 l.jpg

East (CISAT) Campus Conclusions and Recommendations pounds of CO

  • Data very preliminary – obtain at least one year

  • Commonly perceived problems should not obstruct development at JMU

  • Likely will not pay back economically without discounts, grants, or other funding

  • Positive impact on education, reputation, and promotion of renewables
