Comments on 8/26 meeting

PacifiCorp appreciates the opportunity to comment on the working group discussion. PacifiCorp is supportive of the proposed plan and timeline. The Company also requests that the CAISO provide more information on the quality of the data being used in market simulation for testing the imbalance reserve configurable parameters.

PacifiCorp supports the CAISO’s working group plan and timeline. The plan and timeline support active participation from market participants and ample opportunity for the CAISO to share results from testing the configurable parameters.

PacifiCorp requests that the CAISO further discuss data quality during the next working group meeting. At this point in market simulation, PacifiCorp has not seen the CAISO use data that is of good enough quality to ensure the testing results are meaningful. PacifiCorp is unsure if this is because it is the beginning of the market simulation process, or because there are issues with the forecast data. Any further information the CAISO can provide on data quality related to the imbalance reserve product will help stakeholders understand what to expect from the results of testing the imbalance reserve product configurable parameters.
