NOTICE TYPE: M-C062521-02 Settlements
SHORT DESCRIPTION: Implementation Details of NPRR905
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: August 1, 2021
LONG DESCRIPTION: On August 1, 2021, Protocol language associated with Nodal Protocol Revision Request (NPRR) 905, CRR Balancing Account Resettlement, will be implemented.
NPRR905 establishes a scheduled subsequent iteration of the Monthly CRR Balancing Account Invoice which will post on the first Business Day following the RTM Final Settlement posting of the last day of the month on the date specified in the Settlement Calendar. The subsequent iteration will utilize the RTM Final Monthly Load Ratio Share (MLRS) for the distribution of funds in the Load-Allocated CRR Amount (LACRRAMT) payments. For Resettlements to the CRR Balancing Account, the MLRS used will be the same one used for the most recently posted balancing account Invoices for the month.
The Settlement Calendar, located on the ERCOT website, has been updated to reflect the new scheduled “Final” settlement type iteration of the CRR Balancing Account Invoice.
With implementation of NPRR905, the Settlement Calendar field “Version” for all upcoming CRR Balancing Account Invoices will reflect the settlement type (INITIAL, FINAL or RESETTLEMENT) along with the save channel that corresponds to the CRR Balancing Account Invoice calculated Bill Determinants (example: INITIAL_1).
NPRR905 functionality will first be used beginning with the CRR Balancing Account Final Invoice for Operating Month June 2021, and will be posted on August 25, 2021.
The CRR Balancing Account Extract (EMIL ID: COMS-807 | Report Type ID: 12361) changes include:
No changes were required for the CRR Balancing Account Invoice XSD and XSL for NPRR905.
ACTION REQUIRED: Impacted Market Participants should implement changes to their shadow Settlement systems to incorporate the Protocol revisions made by NPRR905.
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.
The NPRR905 and its associated documents can be found on the ERCOT website.
