Texas Nodal

Current issues – EDS environment

• Querying submissions sent via API on the Market Manager – Must update the Bid ID field on the query page:

• If you submit via API, you must enter this to match the Bid ID of your submission

• Updating submissions sent via API on the Market Manager – Must use Bid ID of 051107 when submitting the transaction via API

• When attempting to update submission, a new transaction is created instead • Temporary workaround until fix in for Market Manager

• Intermittent issues with credit limit calculation– Some QSEs had issues with credit limit errors when submitting from

0700-1000 of the DAM• Intermittent issue- so please let us know if you had this problem and send the error• Several issues are the result of some individual data issues with ERCOT• All self-arranged AS transactions will be rejected from 0700-1000 –we are working

on a fix for Tuesday submission


Texas Nodal

Updates – Documentation

• A new version of the Market Manager User Guide is available – New Awards tab next to Notices [will appear soon]– Currently display GetAwardSet only; a download option available in

DAM Execution Status

• ERCOT build-out and migration to integrated EDS4 DAM 4.9.3 (MMS3) environment not yet fully complete

– Approach is to migrate/update from Taylor to Austin in integrated fashion– Submissions this week were supported on MMS2 platform in Taylor

• Move to Austin site supports next level of integration– MMS, MIS, Current Day Reports, Market Manager, API-submission

• Submissions were re-played from Taylor/MMS2 platform to Austin/MMS3 platform yesterday afternoon

– Some QSE received notifications from those migrated submissions– DAM execution still being worked, but parallel focus on completion of integration

in Austin

• Market Manager functionality to view Awards is in Austin, so when DAM successfully executes in Austin, the Market Manager awards will be made available in Market Manager


Texas Nodal

Update on next phase- EDS4 Initial DAM/RUC 4.9.3 Testing

Next week we will continue DAM submissions for Initial DAM Execution

– No changes to the supporting data• Use the same Load Forecast and AS obligations as this week• So for this Tuesday, re-submit the same data used this week with date of April 9
