2- Hurdles
•
•
•
•
•
Lost Time: Lag from 2015 as Transition Year
Going Forward: Time availability of WECC Staff
WECC Re-Staffing
Budget for ABB Support
Uncertainty: Evolving TEPPC Protocol, IRAM
and TEPPC Role (FERC Order 1000)
• Need to develop 2016 Goals for Revised Study

4- Potential Work Plan Adjustments
Go Forward with Reduced/Deferred MWG Work Plan
• Size MWG Work Plan commensurate with WECC Staff availability
• Leverage MWG Gridview User’s/WECC-staff knowledge for
implementation of enhancements w/o ABB support
Position for Future Study Plan and 2026 Common Case
• Validation and Calibration 2024 CC for use in new 2026 Common Case
• Study Results (MWG Perspective): Deeper Dive to identify key metrics
• Analytic Platform: (1) Investigate practical translations between PCM and
PF; (2) support developemnt of zonal model
• Support Long-term Planning Tool: Validation/Calibration
• Support Development of New Resource Adequacy Tool (Gap Analysis)
• Out-reach to engage WECC Groups PCC & RCSG regarding modeling needs
• Host Vendors to share models and modeling techniques
