  1. Windplanner’s100kW Wind Turbine Project for CHRHS • Presented by: The Windplanners

  2. This presentation will address: • Education • Data • Projected Savings • Turbine Location and Details

  3. The first reason is education! • The turbine on campus and the data generated and the process to date has and will continue to provide a wide variety of authentic learning opportunities. • This will be a demonstration site for community-scale wind that is easily accessible in the midcoast. • We want our school campus to symbolize the kind of society we want and need to become.

  4. 6 years of History • New School - Incorporated some renewable technology (geothermal) despite this, operating costs were higher than expected. Efficiency measures taken. What else could we do? Windplanners was established. • MET data - UMass results: wind resource is marginal but viable for this site. • Town ordinance written • Data challenge • UMass third party review

  5. Data Summary *The analysis by UMASS is viewed as the Due Diligence for this project. The Adjusted Wind Speed corrects for any inter-annual variations of wind speed and the method UMASS used is an accepted method within the industry. **The adjusted speed of 4.38 m/s was calculated by Hillary Hanson and Bill Hopwood. The original work was misfiled, so the history of this calculation is lost. ***Output estimates were provided by Northern Power and UMASS.

  6. Wind Data February 2006 – July 2007

  7. What does $510,000 buy? • NPS 100 kW wind machine w/ controls: $380,000 • Transportation to site: $10,000 • Engineering and permitting: $20,000 • Electrical components: $15,000 • Site Work: $15,000 • Foundation: $25,000 • Turbine installation: $15,000 • Electrical Contractor: $25,000 • Startup and commission of machine: $5,000

  8. Funds Raised to Date Maine Community Foundation $7500 Unity Foundation $500 FMC $300 Stephen and Tabitha King Foundation* $35,000 Anonymous $40,000 Anonymous $60,000 Windplanner fundraisers* $1097 Individual Contributions* $457 Anonymous Matching Donor up to $200,000 *Some or all of these funds are being matched Total to Date: $211,000

  9. Projected Savings

  10. Operation & Maintenance Estimate of $3500/ yr after warranty Possible Revenue Options to cover O & M *Sell Renewable Energy Credits (REC) - $.03/kW 105,000kW would generate $3150/yr *Fundraise to establish a reserve *Pay from savings *Other?

  11. Siting the Northwind 100

  12. The Northwind 100 • Direct Magnetic Drive - quiet and cuts in at low wind speeds. • Warranty - 2 years • Reputation - “Best of Breed” for this size turbine. Design life (20 yrs) based on performance in the Arctic and Carribean. • Big jump to go smaller - there are no viable turbines in the 11 - 99 kW class. • Location - manufactured in VT, service and initial carbon impact minimized
