NOTICE DATE: July 15, 2016 NOTICE TYPE: W-A071516-01 Extracts SHORT DESCRIPTION: Issue with DAM Aggregate Credit Exposure report INTENDED AUDIENCE: ERCOT Market Participants DAY AFFECTED: Certain Operating Days February 14, 2013 - present LONG DESCRIPTION: On February 14, 2013, ERCOT first published the Day-Ahead Market (DAM) Aggregate Credit Exposure report (EMIL ID NP4-411-CD). An issue has been detected with the calculation for combined cycle resources as part of the Three-Part Offer (TPO) exposure. In certain cases, the report was underrepresenting the credit that TPOs provide to overall credit exposure. This occurred when two combined-cycled resource offers yielded the same credit exposure calculation. The calculation used by DAM was not affected. ERCOT plans to release a fix the week of August 29 to correct this issue. Additional detail will be provided as information becomes available.
