LONG DESCRIPTION:  The primary bid window for the 2013.2nd6.AnnualAuction.Seq1 Congestion Revenue Right (CRR) Auction will be extended until 17:00:00 CPT on Friday, May 3, 2013. ERCOT has removed a contingency definition (DBNDELM8) in the market systems that could have commercially significant impacts on future auction results. The CRR market now has one Business Day to consider any changes to their bid/offer submissions to reflect this model change for the Sequence1 Auction for July - December 2013.

An update to the CRR Network Model files will be published in the Market Information System (MIS) as soon as they are available, reflecting the removal of the contingency definition (DBNDELM8).

If a second round bid window is needed, it will open at 18:00:00 CPT on Friday, May 3, 2013, and will close at 17:00:00 CPT on Monday, May 6, 2013.
