ADS Update

ADS Scope Currently focus on 10 year base case Align major assumptions between PCM and Power Flow Other power flow cases will be created using existing process Utilize information from planning regions, TPs Information provided by planning regions, TPs will be used in both Power flow base case and PCM dataset Anticipated end products are 2028 PCM Dataset and power flow base case

ADS Scope More detail scope for ADS implementation needs to be developed Better understanding of ADS development process and end products Add more detail to the proposal Examples of issues that are being discussed Types of data to be submitted to WECC  Generators, Transmission, RPS resources, Stability data, anything else? Data format, Concept of Development of Data Quality Protocol (DQP) Roles/responsibilities

ADS Scope Coordination among planning regions, TPs, WECC, and data submitters Timeline, milestone Potential discrepancies between PCM and power flow Solutions issues etc
