Portsmouth RI Town Wind Turbine Generator EBC RI Chapter Program RI Energy Programs – Federal Stimulus, RGGI and Renewable Energy Fund Presented by PEDC Sustainable Energy Subcommittee Gary Gump Chairman April 03,

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
