ERCOT makes available, Retail Market Data of ESIID relationships, characteristics and usage data for the Market Participants to have greater visibility into what is used in the published Market Settlements. These daily updates are included in the SCR 727 ESIID Service History & Usage Data Extracts which may be utilized by LSEs, and TDSPs/MREs to shadow settle load volume and identify data discrepancies between ERCOT and an internal billing system and/or retail customer enrollment system to achieve a greater level of Settlement Statement accuracy.

Ask yourself the following:
How accurate is your internal Customer Enrollment and Usage Data?
Is ERCOT using the correct load volume to calculate your Energy Settlements?
What is the best approach to identify and log relationship and usage variance with ERCOT across multiple LSEs?
Are you loading the Retail Market Data that is published and available for download from ERCOT?

If you are unsure about any of these or feel like these areas could need optimization. We have a solution for you. For more information on how we can help you with ERCOT’s Data Definition Language (DDL) to load the daily .csv files to mirror the ISO sourced dataset for settling ERCOT’s energy market, email us at
