Green is Good
BUT..
Building a WTG is
an Economic Decision
Needs
• Wind
• Space
• Support
• and “all the other things”
Wind and Space
• Sufficient Wind to Generate Power– Wind Models or Met Tower?– Capacity Factor
• Wind Doesn’t blow all the time• Typically CF is 20%-30% over a year
• Space– NIMBY– Some concerns over catastrophic failure– Ice slinging– The higher the better
• Power proportional to cube of wind speed
Support• WTG is a ‘community investment’• Provide current and balanced information and address
“hot buttons”– Counter “misinformation” – Affect on wildlife– Sound– Visual affect
• Public Relations– Need initial buy in– Continual positive reinforcement
• Portsmouth did:– Web Site: updated frequently, FAQs– Mail Survey– Public Workshops– Referendum
• Create Community “Ownership”
… and All the Other Things• Wind Model• Economic Model • Choosing a contractor• Warranties• Insurance• Operation and Maintenance• How to Pay for It• Revenues - Distribution• Electric Interconnect• Public Utilities Commission• Federal Energy Regulatory
Commission• Funding
• Federal/State Legislation• Liaison with State Officials• Large Equipment Access
to Site• Geology• Environment/Health/DEM• Affect on Wildlife• Historical/Archeological • FAA• Town Zoning• Permitting• Risk Management• Project Management
