1. WREZ Model Demonstration: Pacific Northwest
Jerry has to leave – first chance to give feedback and talk about next steps; otherwise lets save that discussion until the end
Agenda: ~ 30 min walk through of the WREZ Dashboard concept
~ 15- min discussion of who is using the modal and how: Tom – feedback from users and planners (TEPCC long-term transmission planning); Tim – model users and training sessions
~15 min discussion of Next steps: LBNL is going to finish a report based on these results, do we want to make Dashboard concept available to others, at

4. Renewable Resource Ranking with Peer Analysis Tool
Portland (8.6 TWh/yr RPS demand by 2029)
Billings (1.4 TWh/yr RPS demand by 2029)
Spokane (1.5 TWh/yr RPS demand by 2029)
Seattle (10.5 TWh/yr RPS demand by 2029)
With and Without Federal Investment Tax Credit (ITC)
ITC is applicable to U.S. resources only
Examine Seattle resource ranking with 765 kV transmission lines
High voltage lines are proxy for lower unit cost of transmission

Seattle
Based on Peer Analysis Tool, resource regions that can supply significant amount of low cost energy include:
Washington (WA_SO)
Oregon (OR_WE, OR_SO)
British Columbia (BC_WC)

Seattle: No ITC in GTM
Peer Analysis Tool Results for “Seattle, No ITC” case suggest there are additional resources with an adjusted delivered cost of $50-$75 that should be considered in GTM

16. Consider Competition for Limited Quantity, but High-Quality Resources
Use Peer Analysis Tool to rank all resources for all load zones
Assign resources to loads to meet RPS demand while not over-allocating limited quantity resources
Assign resources to minimize adjusted delivered cost WECC-wide

18. WECC-wide 33% RPS Results
Base Case Assumptions:
All load zones meet a 33% RPS with energy delivered to their load
Federal ITC is available for U.S. resources
Transmission line cost based on 500 kV single circuit
