NOTICE DATE:  December 1, 2017

NOTICE TYPE:  W-B120117-01 Operations

SHORT DESCRIPTION:  Settlement Points to be retired from Network Operations Model

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  January 4, 2018

LONG DESCRIPTION:  LONG DESCRIPTION:  The following Settlement Points will be retired with the January 4, 2018, Network Operations Model load: CTL_GT_104, CTL_PUN3, CTL_ST_101, and SIL_SILAS_5. These Settlement Points will be non-biddable in the January 2018 CRR Auction. Likewise, the Day-Ahead Market (DAM) will exclude bids and offers at these Settlement Points when they are effectively removed from the model.

Market Participants should not submit bids, offers, or trades that include any of these four Settlement Points for Operating Days January 4, 2018, and beyond. ERCOT will remove any bids and offers on these four Settlement Points prior to the DAM execution at 10:00 on January 3, 2018, for Operating Days January 4, 2018, and beyond. This will prevent DAM awards on points that will not exist in the Real-Time Market on and after January 4, 2018.

The model load is scheduled to be completed around 00:01 on January 4, 2018. Once the model load is complete, all market submissions will be validated against the data within the loaded model, which will not include these four Settlement Points.
