Project Schedule
Project PhasesPhase I – Pre-Bid/FIT SubmissionObjectives: Evaluate Site
Obtain Access to LandPrefeasibility StudyPreliminary Wind StudiesVery High Risk Seed Capital
Observations: Balancing act – Need to spend enough to prove site potential but minimize pain of write off if unsuccessful
Timing: 2008-2009

Phase II – Design, Permitting & EngineeringObjectives: Determine Project Scope
Begin Detailed Wind Data Collection & AnalysisStart Permitting ProcessDo Preliminary LayoutCarry Out Lake Bed Soil TestingEvaluate Turbine OptionsBegin Successive Refinements of Budget &
SchedulesObservations: High Risk Capital
Tasks Must be Undertaken SimultaneouslyPhase Timing: 2010 - 2012

Summary
• Difficult but not impossible• Requires careful planning and execution• Special problems give rise to market
opportunities for Ontario & Great Lakes suppliers
• Possible opportunity to supply services to neighbouring Great Lakes states
• There are no insurmountable problems that are not opportunities.
• “Yes we can!”
