  • May 22nd meeting

    • Assimilated options into a single set of potential renewable transmission corridors

    • Discussed next steps/technical flow studies, etc.



Segment mileage and estimated cost
Segment Mileage and Estimated Cost

  • WGA WREZ model used for construction and right of way costs.

  • Construction cost: $1.8 Million per mile

  • Right of Way cost: $0.23 Million per mile











Bta utility evaluation process
BTA-Utility Evaluation Process

Individual Utility Evaluation of Renewable Resource and Transmission Options

  • Example Inputs to Economic Evaluation:

    • Resource Cost

    • Water Availability

    • Resource Capacity Available

    • Capacity & Energy Benefits

    • Transmission Cost

    • Timing

Utility Coordination & Common Projects Identification

  • Policy Issues:

  • Funding Mechanisms

  • Cost Recovery

  • Siting Constraints

  • Export Markets

File “Top 3” along with plans and funding mechanisms (Due 10/31/09)
