1. CIR I Wind Generation in Alaska: A Case Study Update on the Fire Island wind project

2. Introduction Fire Island : a case study for commercial-scale wind power development in Alaska: Project description Status update Project hurdles Lessons Next steps

3. Project Description Utility-scale wind generation development Project Entity: Wind Energy Alaska, LLC—a 50/50 joint venture between CIRI and enXco Location: Fire Island Current Status: Permitting and final design

4. Project Description 20 to 36 turbines 1.5 megawatts per turbine 30 to 54 megawatt project 3 mile undersea transmission intertie

5. Project Description Turbine facts GE 1.5 megawatt turbine information Towers: 264 feet tall Turbine blades:150 feet long Rotational speed: 18-21 rpm

6. Status Update 8+ years on-site wind and weather data 5 met towers collecting data Preliminary engineering and design completed Project permitting begun

7. Status Update Project timeline 2008-permitting, design & PPAs 2009-Final permitting, PPAs & construction 2010-Construction & commissioning

8. Project Hurdles VOR—VHF Omni-directional Radio Range Project impacts: Reduced number of turbines Reduced hub height Upgrade cost

9. Project Hurdles Permitting Army Corps of Engineers 404 permit ACMP consistency USF&W

10. Project Hurdles Power Purchase Agreements Railbelt utilities (e.g. CEA, HEA & ML&P) Up to 4 individual PPAs with utilities Up to 6 months to negotiate Crucial project item

11. Lessons "Alaska factors” Project development timeline Power integration issues (cost & engineering) Site selection & control

12. Next Steps Complete permitting & design Negotiate & Execute PPAs Construction

13. Conclusion Questions?
