Future Plans

• Continue to operate system effectively as a
  commercial business
• Current plan is to provide 1.25MW power to the
  entire island (including fish processors) with a
  high penetration wind system
• Long-range plan developing a commercial
  greenhouse and cold storage packing complex that
  would require a 2 MW Wind and Hydrogen power
  plant

Construction in 2007

Phase two increases system to 750kw of High
Penetration Wind Power

System shipped from Europe to California to St.
Paul

Wind-Diesel Economics

• System economics are dependant on
• Available wind resources
• Value use for the secondary load
• Delivered price of fuel
• Ultimate cost-of-energy is a function of
• Equipment capital costs
• Maintenance and fuel costs
• Diesel generated power costs are dominated by
  delivered fuel and on-site maintenance
• Wind power system costs are dominated by upfront
  capital costs

Wind-Diesel Economics
Financing Options Commercial standard loan
or lease based financing Grant funding
available for alternative energy
Variables to consider Requires upfront
capital costs and more expensive Reduces
expensive fuel use energy cost Proven
commercial technology

Clean, low Cost and Culturally sensitive
energy
