The California ISO has revised the operating procedure referenced below.
3530I Stranded Load Scheduling - Public Attachment, version 2.4, effective April 21, 2020.
Cascade Scenario #1: ISO should supply energy to (PacifiCorp West (PACW) when serving Pacific Gas and Electric Company (PGAE) load, therefore, the Scheduling Description changed to remove the import to ISO part of the description, and removed CRAG resource IDs from the Valid Stranded Load IDs column. Import Tie: added Energy should stay in PACW to serve PGAE load. The Existing Transmission Contract Calculator (ETCC) limits were changed to 0/0, as in this scenario Cascade is out of service.
Cascade Scenario #2: In the ETCC Change column, replaced "PACW does have Transmission Ownership Rights (TOR) import rights at MALIN, right now they have 40 MW. The MW amount can change quarterly" with "Determined by operating conditions" because the TOR information is not relevant information and the Cascade limit could be full or derated. Import Tie: added Energy should stay in PACW to serve PGAE load. Removed the CRAG Import and MALIN500 Export resource IDs, as they are not needed for this scenario. Removed BPA from Adjacent BA(s) since it is not necessary to schedule through BPA for load #2.
Updates to Sandy Load #1  and Valley Electric Association (VEA) load #1. Removed VEA load #2. Added VEA Mitigation for no Under-Voltage Load Scheduling (UVLS).
