Renewable Energy Development
• State Renewables Portfolio Standard (RPS)
– California 33% by 2020– Potential National RPS
• Production and Investment Tax Credits
• GHG Emission Reduction Legislation

Wyoming Proposed Transmission Lines
• 7 extra-high voltage• Issues: impact,
reliability, cost, and spacing of lines
• Spacing affects BLM ROW application processing

Transmission Line Separation
• WIA Board of Directors funds independent study to address issues
• Published August 2009

WGA and DOE - Western Renewable Energy Zones (WREZ)
• WREZ Phase I Report Published June 2009
• Includes Hub Map of Renewable Resource Potential

Western Area Power Administration and the ARRA
• TIP Purpose: “…constructing, financing, facilitating or studying construction of new or upgraded transmission facilities to deliver or facilitate delivery of renewable resources…
• Applications submitted April 2009

Wyoming Wind Collector and Transmission Task Force
• Develop a coordinated, staged, conceptual plan for a collector system
• Accommodate the interstate transmission lines and corridors required to collect and export these new resources

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

Current Effort – Subtasks 1.1 and 1.2
1.1 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

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

Going Forward (Cont’d.)
Considerations Outside Scope of Work• Integration of wind generation with other energy sources
