867s Received on Cancelled Service Orders

3

SituationERCOT periodically receives 867_03 Finals and 867_04s for service orders that are Cancelled in ERCOT systems. The Service Order Sub-Statuses that are considered Cancelled are: CR Requested, Customer Objection, ERCOT Operating Rule, Manual, Permit Not Received, with Exception, Unexecutable and Rejected by TDSP. This can indicate an out-of-sync condition between the TDSP and ERCOT.

Mechanism for Handling 867 RCSO:Step 1: ERCOT produces 867RCSO data each Friday and submits a report file to each TDSP

and CR via the ERCOT PortalStep 2: The TDSPs review the report line items and take one of the following actions:

a) If the TDSP has cancelled the service order, no further action is requiredb) If the TDSP has completed the service order, they will initiate a day-to-day FasTrak issue and work with ERCOT to get ERCOT systems changed to complete. Completion of cancelled service orders will require the approval of the CR initiating the transaction.

(Note: For Cancel by Customer Objection, the TDSP will honor the cancel in their systems)
