TEST Comment

Renewable Northwest recommends consulting with the Northwest Power and Conservation Council to fold in climate change adjusted datasets into the river flow and load forecast modeling for the 20-year Extended Planning Horizon scenarios. Using primarily historical data for river flows to project the next 20 years might not represent the system we will see going forward. An option could be studying the impacts of these datasets as a sensitivity. Please see our more detailed comment in Modeling and Data Questions and Recommendations section. Thank you for considering these comments. 

How will the study address IRPs that do not include most current public policy requirements (i.e PGE IRP)

How will the study deal with market purchases in IRPs? How will the study deal with IRP resource additions that are "generic" or not associated with a specific geographic region?  How will the study confirm that transmission exists (or not) for these market purchases or generic generation resources?

The study should explore whether

We recommend reliability studies to include 

• Summer
  • Peak load
  • Peak day sunset 
  • Peak day energy with storage charging
• Winter
  • Peak evening load
  • Peak day energy storage changing
  • Light load high renewable scenario

We recommend that the production cost modeling study start by developing a reference case that is based on a current vintage WECC Anchor Data Set (ADS) with any additional modeling updates or refinements that study team members wish to provide.  Then, scenario cases including test years further in the future could be developed.  The reliability studies could inform assumptions about additional constraints to monitor in the PCM study.
