CIRI Wind Generation in Alaska: A Case Study Update on the Fire Island wind project
Introduction • Fire Island: • a case study for commercial-scale wind power development in Alaska: • Project description • Status update • Project hurdles • Lessons • Next steps
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
Project Description • 20 to 36 turbines • 1.5 megawatts per turbine • 30 to 54 megawatt project • 3 mile undersea transmission intertie
Project Description • Turbine facts • GE 1.5 megawatt turbine information • Towers: 264 feet tall • Turbine blades:150 feet long • Rotational speed: 18-21 rpm
Status Update • 8+ years on-site wind and weather data • 5 met towers collecting data • Preliminary engineering and design completed • Project permitting begun
Status Update • Project timeline • 2008-permitting, design & PPAs • 2009-Final permitting, PPAs & construction • 2010-Construction & commissioning
Project Hurdles • VOR—VHF Omni-directional Radio Range • Project impacts: • Reduced number of turbines • Reduced hub height • Upgrade cost
Project Hurdles • Permitting • Army Corps of Engineers 404 permit • ACMP consistency • USF&W
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
Lessons • "Alaska factors” • Project development timeline • Power integration issues (cost & engineering) • Site selection & control
Next Steps • Complete permitting & design • Negotiate & Execute PPAs • Construction
Conclusion • Questions?
