TX SET finalized a redline correction of the Solution to Stacking which will be presented to RMS in October. Now that both the RMGRR and Stacking documents are finished, this issue is being closed.
Action Item: All TX SET members will need to take this issue and the redlined changes back to their internal teams for review and questions. All questions, issues or concerns will be needed at the September TX St meeting for discussions and/or correction. TX SET will have final sign-off on the redlined changes for this issue at the September meeting.
TX SET decided to go ahead and submit the rmgrr but hold off on finalizing any changes to the stacking document until they are reviewed again next month.

RMG and MIMO Stacking Document
Description:
The MIMO Stacking Document and the current Retail Market Guide are inconsistent with the current logic and should be updated.
Current RMG states Leapfrog (FRG) only occurs on completed orders.
MIMO Stacking Document states the logic occurs on completed orders or on orders that are pending with a later date than the date on the backdated transaction.
ERCOT’s system actually does a combination of the above. ERCOT will accept a back-dated transaction when there is a scheduled order if the pending (scheduled) order has not reached its evaluation window.
Reason:
Update the Retail Market Guide and the MIMO Stacking document to state what evaluation ERCOT systems currently perform. (Reject the transaction for FRG if the transaction is completed or has reached its evaluation window).
