icfi.com 11 Current Status WIA contracted with ICF to develop a conceptual design of a collector system One meeting and several conference calls held to date Scope of Work is complete and ICF began work in October
icfi.com 12 Scope of Work Tasks 1. Technical Analysis* 1.1: Develop Analysis Scenarios* 1.2: Perform Reliability Analyses* 1.3: Update Energy Corridor Map 1.4: Estimate Costs* 1.5: Summarize the Collector System Design Alternatives* 2. Commercial Structure 3. Administrative/Outreach * Funded subtasks Start October 2009 Task 1 Technical Analysis Task 2 Commercial Analysis Task 3 Administrative Support Collector System Design Alternatives
icfi.com 13 Current Effort – Subtasks 1.1 and Develop Analysis Scenarios ( in progress ) Examining two wind resource development options Analyzing two collector system design options: radial vs. networked 1.2 Perform Reliability Analysis (start 11/09) Performing engineering feasibility analysis to ensure basic security and reliability of conceptual design for a 15GW system Developing a starting point for evaluating collector system design options from a cost basis
icfi.com 14 Going Forward
icfi.com 15 Going Forward 1.4 Estimate Cost of Collector Design Options Estimate cost of design options Rank options based on cost 1.5 Summary of Technical Analysis Identify collector system elements common to all scenarios Discuss possible integration with existing grid Discuss possible staged development of the collector system Describe radial and networked design options and discuss trade-offs
