3. 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.

Concerns voiced:  Decision to move to T+7 this summer with limited Final (59-day) Settlements to examine the change between Initial and Final settlement.  Move to T+7 without impacts of moving Data Aggregation up by one day.  Need more data analysis to estimate impact of moving data aggregation to an earlier date based on available data.  ERCOT Staff started providing more analysis on the impact the reduced timeline to 7 days and less to the availability of meter data during the weekly Monday Webex meetings.  http://www.ercot.com/committees/board/tac/cops/cswg/ key documents http://www.ercot.com/committees/board/tac/cops/cswg/ key NPRR509_20130520.xls (% of load data read by meter type AMS, NIDR, NOIE etc.) Reduced Settlement Timeline Issues List.xls Unless something significant is observed between now and July 2, 2013 (TAC), COPS will recommend to TAC moving as planned to reduce the timeline to 7 days starting with August 1, 2013 OD.
