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

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
slide4
Tower siting

Regulations

Safety

Visual impact

Wind modeling (WAsP)

Avian mortality

Maintenance

Noise

Grid connection

Economic analysis

JMU East (CISAT) Campus Study

  • More detailed site assessment dealing with issues such as:
slide5

5000BC

Sailboats on the Nile River

1940

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

1854

American windmill invented

1300AD

Windmills in the Netherlands

slide6

What Is Wind?

  • Driven by the sun
  • Differences in pressure
  • Hadley convection cells
  • Coriolis Effect

Hadley Cell Model (Western Illinois University)

slide7

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

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

Siting of Wind Turbines

  • The concept of micrositing
  • Topographical maps
  • Freedom from obstructions
slide13

Materials

  • Loan agreement
    • Borrowers eligibility
    • Borrowing process
  • Application
    • Site information
    • Purpose
  • Contract
slide14

Publicity

  • Website
  • Press release
    • Media relations
    • Written in a non-technical language
    • Distributed across the state
    • Contact information provided
slide15

slide19
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

SBALP Recommendations

  • Better outreach to public
  • More stringent application process, include more parameters
  • Expand website
  • Establish school contact, answering machine, mailbox, etc.
slide21

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

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

Objectives

  • Analyze:
    • Relevant issues and public misconceptions
    • Preliminary economic analysis of wind turbine
    • Non-market benefits
slide25

Regulations

  • No restrictions on proximity to roads, parking lots, etc.
  • Zoning, permitting, etc. handled by JMU
  • Federal Aviation Administration (FAA) requirements
slide26

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

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

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

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

Required WAsP Inputs

  • Wind Atlas
    • Meteorological Tower, Observed Wind Climate
  • Turbine Site
    • Obstacles, power curve
  • Site Description
    • Topography, Roughness, Obstacles
slide32

WAsP – Wind Atlas and Turbine Site

  • Meteorological station
    • Observed wind climate
  • Turbine site
    • Power curve (Excel and XL.1)
slide33

  • Mean speed (5.15 m/s)
  • Resource grid
slide36

Economic Analysis

  • Turbine cost
    • Bergey Excel (10 kW)
    • Bergey XL.1 (1 kW)
  • Cash flow analysis
  • Simple and discounted payback
  • Sensitivity analysis
slide42

Economic Conclusions

  • Bergey Excel and XL.1 are unlikely to pay back over lifetime
  • Ways the turbine may become more cost-effective
    • Reduce JMU’s initial investment
    • Verify wind resource
slide43

Non-Market Benefits

  • Education
  • Reputation
  • Promotion of renewable energy
  • Emissions benefits
slide44

Education

  • “The college seeks and creates new models through innovative curriculum development and uses the advancing knowledge of science and ever-evolving technologies to integrate the rapidly shifting world into the professional lives of faculty and students.”
        • Excerpt from CISAT mission statement
      • Growing, sustainable technology
      • Hands-on learning experience
      • Benefits for a variety of courses
slide45

Reputation

  • National and local recognition
  • Solar panels and wind turbine – technologically advanced university
  • Visible symbol for prospective students
slide46

Promotion of Renewable Energy

  • Raise local and state awareness
  • Encourage wind energy use
  • Provide opportunity to educate
slide47
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

East (CISAT) Campus Conclusions and Recommendations

  • 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
