SHORT DESCRIPTION: Report issue for Operating Day December 10, 2017

INTENDED AUDIENCE: ERCOT Market Participants

DAY AFFECTED: December 12, 2017

LONG DESCRIPTION: On December 12, 2017, the 2-Day DAM Bids and Offers Reports (EMIL ID NP3-909-ER, Report ID 13055) was posted with incomplete data. The file contained all the PTP Obligation Bid data, and the Total Cleared Energy Bids and Offers by Disclosure Area, but did not contain the csv with the system-wide sums for Total Cleared Energy Bids and Offers. The incomplete file has been removed from the MIS. A new file was posted today, December 13, 2017 at 15:18 (ext.00013055.0000000000000000.20171213.151823140.2_Day_DAM_Offers_and_Bids.zip) and includes the missed csv. The issue has since been resolved, and today’s file posted normally.

ERCOT recommends replacing the previously downloaded file with the updated file posted at 15:18 on December 13, 2017.
