Arizona Wind Resource Potential

• Wind Mapping
• August 2003 - 1st High Resolution Wind Power Maps
  (DOE, APS, TEP SRP funded)
• Developed by TrueWind Solution, validated by NREL
  and reviewed by APS, TEP SRP
• Mean annual seasonal wind speeds _at_ 30, 50, 70
  and 100 meters

Arizona Wind Resource Potential

• Wind Mapping
• Wind power density at 50 meters
• Validated by 50 measurement stations 30 year
  historical upper atmosphere and ground surface
  data
• Margin of error 10 speed and
• 20 power

Arizonas Wind Resource Potential

• Wind Maps represent regional information not
  micrositing
• Wind data shows good potential for load-following
  resource
• Major resource areas (Gray Mountain, Kingman and
  Springerville) have significant transmission

12
Development Activities

• Half dozen projects are in various development
  stages
• Wind monitoring is being conducted on private and
  public lands
• Transmission availability and adequacy is being
  studied

13
Development Activities

• NAU RD
• Anemometer loan program
• Wind mapping service
• Evaluating the Most Promising Sites for Wind
  Energy Development in Arizona, Acker, Norman,
  Duque 2004
• Findings Levelized bus bar cost of energy for
  three selected Arizona sites is 4.21 (class 5)
  -5.04 (class 3) cents/kWh without transmission,
  ancillary services or Production Tax Credit

Interwest Energy AllianceProposal

• Interwest Energy Alliance Letter of February 25,
  2004
• Interwest Energy Alliance recommends that the
  Arizona Corporation Commission increase its
  commitment to renewable energy significantly by
  implementing a 1,000 MW Renewable Energy
  Portfolio Standard, without a surcharge, for
  eligible renewable energy technologies.

15
Conclusions

• Arizona has complete statewide mapping for wind
  resources
• Maps demonstrate a significant developable wind
  resource with access to transmission
• There is considerable micrositing being conducted
  in the state
• Active competition among developers will create
  lower prices
• Costs are declining and technology is improving
  for slow speed wind (class 3)

16
Conclusions

• Developers will build projects in state due to
  Arizonas large market (population and
  electricity demand) and load growth
• 1,000 MW of wind development
• 1 billion in investment
• Significant resources of wind and other renewable
  technologies existing in Arizona that can provide
  large portion of CRRES
