NOTICE DATE:  November 9, 2018
NOTICE TYPE:  M-C092917-04 CRR
SHORT DESCRIPTION:  Reminder – CRR system changes for the implementation of the remainder of NPRR831
INTENDED AUDIENCE:  CRR Account Holders
DAYS AFFECTED:  November 16 and 19, 2018
LONG DESCRIPTION:  On November 19, 2018, ERCOT will be implementing the remaining Protocol language related to Nodal Protocol Revision Request (NPRR) 831, Inclusion of Private Use Networks in Load Zone Price Calculations, in Sections 4.5.1, DAM Clearing Process, and Section 7.5.1, Nature and Timing. NPRR831 requires ERCOT to update market systems in order to calculate a net Load value for each Private Use Network that will be included in the Load Zone price for all markets, Day-Ahead Market (DAM), Real-Time Market (RTM), and Congestion Revenue Right (CRR) Market, when the Load is a net consumer from the ERCOT Transmission Grid.
As part of the CRR Market User Interface (MUI) Upgrade on November 19, 2018, the language in paragraph (5) of Section 4.5.1 and paragraph (3)(b) of Section 7.5.1 will be unboxed, and ERCOT will implement the following changes for the CRR portion of NPRR831.

·         Include the net Private Use Network Load distribution factors in CRR Auctions, when allocating CRR offers and bids with source and sink at a Load Zone.

·         Net Private Use Network Load data will be redacted from the CRR Network Model postings for CRR Auctions occurring after the implementation date.
Note that due to the timing of the MUI Upgrade implementation, net Private Use Network Load data will be redacted for the first time from the CRR Network Model postings for the following two models, which will both post on November 16, 2018, for auctions to be run after the upgrade is implemented.

·         2019.JAN.Monthly.Auction CRR Network Model

·         2020.1st6.AnnualAuction.Seq3 CRR Network Model
ADDITIONAL INFORMATION:  Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
