    PURPOSE OF PRESENTATION
   Provide background on the challenge of wind
    resource evaluation
   Describe the wind prospecting process
   Explain the resource validation process
   Review the principles of wind plant micrositing
   Challenges facing utilities and developers in the
    Northwest on the resource side
   Opportunities on the resource side
    The Challenge of Wind Resource
              Evaluation
   Finding locations with strong, persistent, well behaved
    winds that:
   Are within the utilities area of interest or near the wind
    developers identified customer
   Are not more than 5 miles from transmission lines
   Have sufficient land area for an economically viable
    project
   Will not present any environmental or legal obstacles
    and resistance to development is not expected
  PROSPECTING FOR WIND
              Who has seen the wind?
                 Neither you nor I
       But when the trees bow down their heads
              The wind is passing by.

   PROSPECTING PROCESS

 ClimatologicalStudy
 Prospecting Survey

 Rating and Ranking the Sites
         CLIMATOLOGY
 Wind data collected by the National
  Weather Service, Coast Guard and the
  FAA
 Wind Maps

 Upper Air Data
THE PROSPECTING SURVEY
How do you find something that is invisible?


   Trees and stones will teach you that which
    You could never learn from the masters.
            St. Bernard of Clairvaux
    What makes a good wind site?
   Strong steady winds
   Good exposure to the wind
   Ridgelines oriented perpendicular to the
    prevailing wind direction
   Moderate slopes
   Low surface roughness or lack of vegetation
           TOOLS OF THE WIND
              PROSPECTOR
   Wind shaped trees and bushes
   Plants and trees characteristic of wind zones
   Active sand dunes and sand scours
   Persistent snow sweep
   Topographic features that favor the wind
   Judging wind exposure
   Talking with local people
   Satellite Imagery
   Aerial surveys
   Ground level Inspection
   Three dimensional Analysis

    VALIDATING THE RESOURCE
   Why?
   How?
   How many locations?
   What does it cost?
   How long do you measure the wind?
   What parameters do you measure?
   Who should analyze the data?
CHALLENGES IN THE PACIFIC
      NORTHWEST
   Very few great sites left that are feasible.
   Lack of transmission lines or transmission
    capacity near good resource sites
   Environmental constraints
   Institutional Constraints
   Political and Price Uncertainty
            OPPORTUNITIES
   Bigger and more efficient machines
   Increasing acceptance and understanding of
    wind by utilities
   Better forecasting of this variable resource
   Greater appreciation by utilities that a diverse
    energy resource stack is important
   The public’s willingness to pay slightly more for
    “green energy”
