3 COPS MAJOR DISCUSSION ITEMS cont. Discussed Emergency Response Service (ERS )Reporting  MPs raised concerns regarding the lack of back up data in the extracts.  For the pilot programs implemented, ERCOT used SAS code vs.Lode Star due to its flexibility.  Therefore pushing data to the extracts to be received by the MPs using the current delivery methods is not possible.  The MPs’ need for back up data to be provided in the extracts for the future projects including pilots need to be also taken into consideration. Use of NERC Holidays instead of ERCOT holidays for the ERS programs  MP may bring an NPRR in the following months to address this issue.
