11. We entered bilateral trades six days ago and the status still reads “Pending Credit Check”. Shouldn’t this have changed by now? Since the CRR system is not yet integrated with CMM, the CRR team needs market participants to tell us about pending bilateral trades because we have no way for us to know of them otherwise. The workaround until integration is for us to manually approve trades. However, if we don’t know about them, we can’t approve them. Please let us know when there are trades that need to be approved. 11 6/14/2016

12. What type of nodal pricing is available and in what format and how will CRR pricing be provided? Clearing prices for CRR Auctions will be provided in the downloads section of the CRR application (only for paths on which there were bids) immediately upon the conclusion/approval of each auction run and in the MIS shortly thereafter. As to format, I have attached the results from the last CRR auction in market trials in csv and xml format. 12 6/14/2016

13. Where on the MIS do I find the list of Settlement Points that are missing from the CRR Network Model On the Market Trials website, in the Key Documents section, there’s a Settlement Point file: http://nodal.ercot.com/readiness/markettrials/index.htmlhttp://nodal.ercot.com/readiness/markettrials/index.html Column B of this document represents all possible SPs. You will want to enter the CRR application and find the SP file for the auction you are researching – you’d do this from the Downloads link. Do a compare from the possible SPs to the ones found in this document to locate the missing SPs from the CRR Network Model for the auction in question. (Note however that CRR does not use the Combined Cycle Train Logical Resource Node types, so their absence on the CRR report is not an error. 13 6/14/2016
