NOTICE TYPE:  M-A100423-01 CRR

SHORT DESCRIPTION:  Mapping Documents updated within the CRR Network Models for the 2023.NOV.Monthly.Auction and 2024.1st6.AnnualAuction.Seq1

INTENDED AUDIENCE:  CRR Account Holders

DAY AFFECTED:  October 4, 2023

LONG DESCRIPTION:  ERCOT has updated the Mapping Documents within the Congestion Revenue Right (CRR) Auction Network Models for the 2023.NOV.Monthly.Auction and 2024.1st6.AnnualAuction.Seq1. No other changes were made to the models.

A recent upgrade to the CRR topology processor changed the naming convention for the transformers in the RAW file, which resulted in the Mapping Documents incorrectly identifying all the autotransformers as ‘Temporary Split Bus.’ A workaround is in place to correct the Mapping Documents until a long-term solution is implemented.

The updated Mapping Documents are available on the Market Information System (MIS) Secure Area.
