4-CP Issue – July 2016

Randy Roberts presented information regarding the 4-Coincident Peak (4-CP) interval for July 2016, stating that there was an issue caused by a trip of the east Direct Current Tie (DC Tie) which resulted in deployment of additional generation over a nine minute period, and affected the 4-CP calculation. Market Participants discussed Public Utility Commission of Texas (PUCT) Docket No. 46604, Application to Set ERCOT Wholesale Transmission Service Charges for 2017, and possible solutions that could be implemented either through system changes or Protocol revisions.

Change impacting Day-Ahead Make-Whole Guaranteed Cost portion of Day-Ahead Make-Whole Payment Formula

Mark Ruane stated that in November, ERCOT Staff detected an increase in Day-Ahead Market (DAM) Make-Whole Payments following the implementation of Nodal Protocol Revision Request (NPRR) 617, Energy Offer Flexibility; and that the increased payments were the result of a data mismatch affecting Three-Part Supply Offers with null values for startup and minimum Energy for the day, which did not meet the criteria to be self-committed by DAM in paragraph (3) of Protocol Section 4.4.9.1, Three-Part Supply Offers. Mr. Ruane also stated that ERCOT analyzed all impacted Operating Days, and that none met the 2% threshold for resettlement of the DAM, a solution was implemented effective on the November 16, 2016 Operating Day, and ERCOT Staff is assessing ways to more rapidly identify Settlement anomalies going forward.

2% Resettlement Rule Discussion

Market Participants briefly discussed the resettlement threshold percentage. The topic was assigned to the Communications and Settlements Working Group (CSWG) for further consideration.
