SHORT DESCRIPTION: Implementation Details for NPRR867
INTENDED AUDIENCE: Counter-Parties and CRR Account Holders
DAY AFFECTED: September 10, 2021
LONG DESCRIPTION: On September 10, 2021, Protocol language associated with Nodal Protocol Revision Request (NPRR) 867, Revisions to CRR Auction Credit Lock Amount to Reduce Excess Collateral, will be implemented. Following the implementation of NPRR867, ERCOT will assign the Available Credit Limit (ACL) locked for a CRR Auction for each Counter-Party participating in an auction as the lower of the Counter-Party’s:
a. Requested credit limit;
b. ACL at the time of the closure of the auction bid submission window; or
c. Pre-auction screening credit exposure amount.
The first auction for which the collateral reductions will take place will be the 2024.1st6.AnnualAuction.Seq6 CRR Auction, which will close on September 16, 2021.
This software release will also include updates to the public operator messages posted to the CRR Market User Interface (MUI) at the close of an auction bid window. Details about the number of submitted transactions and grouped baseload CRRs will be provided for each auction, including a separate message for each Time Of Use (TOU) for long-term auctions. These new messages with align with how ERCOT determines the need for a transaction adjustment period for long-term auctions in relation to NPRR972, Enhancing Existing CRR Transaction Limit Process, which was implemented in December 2019.
ADDITIONAL INFORMATION: Pursuant to Nodal 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.
NPRR867 and associated documents can be found on the ERCOT website.
