4. 4 COPS MAJOR DISCUSSION ITEMS-(June Meeting) CRR June monthly auction invoice issue  On May 17, the June Monthly CRR Auction Invoices for four NOIE CRR Account Holders were posted with duplicate CRR IDs  The four invoices were immediately removed from the MIS  Since the number of MPs impacted were less than 10, no Market Notice was send out, instead each MP’s AR was contacted directly  Settlements has implemented an automated validation to check for duplicate CRRIDs on Auction Invoices NERC vs ERCOT holidays  Request came from an MP to change the use of NERC Holidays instead of ERCOT Holidays for ERS procurement  Based on comparing the ERS Fleet load for the ERCOT holidays versus the NERC holidays the ERCOT holidays more closely align with non-business hours.  Adopting the NERC Holidays would place the ERS participants at risk of failing both availability and deployment metrics for those days  ERCOT will continue to use ERCOT holidays  However ERCOT Staff agreed to work with MP to provide a way of including the future holidays either in extracts or as a code so that MPs can use it in their shadow settlement system. (NPRR may be required) (
